- HDMI Format — This item lets you set the HDMI output format.

To select the format, select HDMI Format from the Output submenu, then press any of the arrow buttons to step through the items. The choices are:

• Auto (based on the EDID of the sink) (default)
• DVI RGB 444
• HDMI RGB 444 Full
• HDMI RGB 444 Limited
• HDMI YUV 444 Full
• HDMI YUV 444 Limited
• HDMI YUV 422 Full
• HDMI YUV 422 Limited

All output rates include their correct H/V sync polarity per VESA or SMPTE specs, along with VIC codes for SMPTE resolutions.

- Input AFL — This item lets you turn the Extron Accu-RATE Frame Lock (AFL) on and off. The default is Off.

When enabled, this mode locks the output vertical refresh rate to the vertical refresh rate of the currently selected input using Accu-RATE Frame Lock technology. This ensures no frames of the input are repeated or dropped due to frame rate conversion. Input AFL mode can cause glitches or interruptions in the output sync when a new input is selected, or when a new signal has been routed to the selected input, as the DSC locks to the new vertical refresh rate.

NOTE: AFL locks the output refresh rate to similar input rates. If the input signal is locked on a rate that is not considered a standard HDMI output or that is very different from the current output setting, the DSC may not output a signal. The image may not display or may blink.

If no input signal is detected (AFL disabled), or if locking to the input signal is not possible, a free running pixel clock is generated by the DSC.

Output Submenu — DSC HD-3G A

This submenu allows you to configure the output of the DSC HD-3G A.

NOTE: The DSC HD-3G A has some different items on this submenu from DSC 3G-HD A (see Output Submenu — DSC 3G-HD A on page 24).

- Output Resolution — This item lets you select the resolution and refresh rate for the connected output display. The DSC HD-3G A has a range of factory-loaded resolutions and rates from which to choose (see the resolutions table below for the available resolutions and rates). Different refresh rates are available depending on the selected resolution.

1. Select Output Resolution from the Output submenu.
2. Press the ◀ or ▶ button to select a resolution.
3. Press the ▲ or ▼ button to select a rate for the resolution.
4. When you enter a new resolution, a message appears on the display, prompting you to press Enter to confirm your selection. If you do not confirm it within 15 seconds, the scaler returns to the previously selected resolution and rate.

Genlock/AFL —

• AFL (Accu RATE Frame Lock) locks the output vertical refresh rate to be to that of the applied HDMI input signal.
• Genlock locks the output vertical refresh rate to that of an applied reference sync signal.

NOTE: Genlock and AFL lock the output refresh rate to similar reference or input rates. If the input reference or the vertical refresh rate of the HDMI input signal do not adhere to SMPTE frequencies, the DSC may not output a signal, or the image may blink.

To select the genlock or AFL mode, select Genlock/AFL from the Output submenu, then press any of the arrow buttons to step through the items. The choices are:

• Off — The output runs at the selected output frame rate using an internally generated clock. This selection is the default.
• Input AFL — The output is locked to the vertical sync of the HDMI input signal. This is valid only if HDMI input frame rate matches that of the DSC scaled output rate.
• SDI Genlock — The genlock input and loop-out are used for sync reference. The Genlock input supports bi-level and tri-level sync.

SDI Genlock locks the output vertical refresh rate to the applied analog genlock input on the DSC HD-3G A. In the SDI Genlock mode, the output resolution and refresh rate of the scaler must be set to exactly match the applied analog genlock signal to ensure a true genlock to the applied SDI Genlock signal.

If the applied SDI Genlock signal does not exactly match the resolution and refresh rate of the DSC HD-3G A output resolution, the scaler locks its output vertical refresh to that of the applied SDI reference (frame lock), which may result in more jitter and may not work for some interlaced signals.

If no SDI Genlock signal is detected, or if the detected SDI Genlock signal would result in a greater than 165 MHz pixel clock, the DSC generates a free running pixel clock.

The Genlock and AFL status can be queried via SIS command (see the Genlock Offset and Input Lock (Accu-Frame Lock [AFL]) commands on page 55) or via PCS (see the DSC 3G-HD A and DSC HD-3G A Help File).

NOTE: If the applied Genlock reference signal differs in resolution or refresh rate from the DSC scaled output resolution, then proper genlock cannot be guaranteed.

- SDI Genlock Offset — This item lets you adjust the horizontal and vertical offset of the genlock signal. (This feature can be adjusted only if the DSC is set for SDI Genlock and actively locked to a reference input.)

Use the ◀ or ▶ button to adjust the horizontal (H) offset value. Use the ▲ or ▼ button to adjust the vertical (V) offset value.

DSC HD-3G A: Audio embedding

In PCM multi-channel mode, the DSC HD-3G A embeds up to eight channels of PCM HDMI audio onto the first four pairs of AES channels on the SDI output, in sequential order. In LPCM two-channel mode, the first pair of SDI audio channels is used (you cannot select a channel pair on the DSC HD-3G A).

All audio inputs on the DSC HD-3G A are automatically delayed to compensate for internal video processing.

The table below shows the channel pair mapping for the DSC HD-3G A.

SDI Embedded Audio	HDMI Audio Signal
Pair 1 – Channel 1	L – Left speaker
Pair 1 – Channel 2	R – Right speaker
Pair 2 – Channel 1	LFE – Low frequency extension (woofer)
Pair 2 – Channel 2	C – Center
Pair 3 – Channel 1	LS – Left surround
Pair 3 – Channel 2	RS – Right surround
Pair 4 – Channel 1	SBL – Surround back left

Figure 21. Advanced Submenu

The following items are available on the Advanced submenu:

- Test Pattern — This item lets you select a test pattern to use in setting up a display when outputting different resolutions. The following test patterns are available:

Color Bars (8) Crop Crosshatch Alt. Pixels Grayscale Blue Mode Audio Test

Figure 22. Test Pattern Items

NOTES:

• The Audio Test pattern displays a crop pattern with OSD text AUDIO TEST. It also outputs pink noise at 48 kHz, 24 bit.
• By default all test patterns except Blue Mode include a single pixel wide crop pattern line.

- Screen Saver and Timeout — This item lets you enable screen saver mode, in which the video output is muted to black or blue if there is no active input video signal. It also lets you specify the output sync timeout. Screen saver mode allows display devices (such as an LCD panel, plasma screen, or projector) to enter low power or standby state to increase panel or lamp life.

• To select the screen saver color, press the ◀ or ▶ button. The options are Black (default) or Blue.
• To set the sync timeout, press the ▲ or ▼ button. You can select a duration of 1 through 500 seconds before the output sync times out. The default is Never, meaning that the sync does not time out.

NOTE: The DSC exits screen saver mode when a front panel button is pressed or an active input is detected. If the unit is in front panel lock (executive) mode (see Locking the Front Panel (Executive Mode) on page 39), front panel button presses have no effect on screen saver mode.

- Aspect Ratio — This item lets you set the aspect ratio to Fill (fills the entire output screen) or Follow (follows the native aspect ratio of the input).

• In fill mode, if you want to set an aspect ratio adjustment for a single input rate, you can select the correct size and position manually from the Picture Controls submenu (Image Size and Position) (see Picture Controls Submenu on page 21).
• In follow mode, each input rate is displayed with its native aspect ratio (4:3, 5:4, 15:9, 16:9, 16:10) with the correct letter box or pillar box settings, visible under the Image Size and Image Position items on the Picture Controls submenu.

If you want a single input to fill the screen in follow mode, you can manually set the Image Position item on the Picture Controls submenu to , and set the Image Size to match the current output rate X,Y.

• Auto Memory — This item lets you enable or disable Auto Memory. When Auto Memory is enabled, the DSC stores the current input configuration and picture control values as an input preset. All values are stored except preset name, film mode, and audio gain or attenuation (see Auto Memories on page 37 for more information).
• Overscan — This item lets you select a default overscan mode to apply to SMPTE input rates (480i, 576i, 480p, 576p, 720p, 1080i, 1080p, and 2K). This zooms and crops SMPTE inputs to mask edge effects and ancillary data that may occur in broadcast signals. The selections are 0% (the default), 2.5%, and 5%.

NOTE: If the overscan mode is not 0%, when Auto-Image is performed on an SMPTE input rate, it refers to the default input values for sizing and centering instead of performing a true Auto-Image.

• Temperature — This read-only field shows the internal temperature of the unit in Fahrenheit (left value) and Celsius (right value).
• Factory Reset — This item lets you reset the unit to its factory-installed values (removing any user-defined values) while retaining the current firmware version.

To reset using the OSD, press and hold the Enter button until Factory Reset is displayed. The message remains for approximately 1 minute after the reset is complete to allow time for the display device to sync with the DSC output. (The equivalent SIS command is ZXXX <]>.) For other reset methods, see

Resetting on page 39.

Communication Screen

This read-only screen enables you to view the RS-232 remote port baud rate (left) and port type (right). The protocol for this port is 9600 baud, eight data bits, no stop bits, and no parity. You cannot change any of these port parameters. (This screen is the same on the DSC 3G-HD A and the DSC HD-3G A.)

Device Info Screen

This read-only screen provides a quick view of certain selections, parameters, and status information for the DSC. All these items are also on other DSC screens. However, the Device Info screen provides them all on a single screen for a system overview. This screen differs between the two DSCs as follows:

• The DSC 3G-HD A Device Info screen (see figure 23) shows the AFL On and Off status and the display resolution and refresh rate (no genlock information).
• The DSC HD-3G A Device Info screen shows the Genlock/AFL On and Off status (no separate items for AFL or the display rate).

Auto-Image

When Auto-Image is performed, the DSC attempts to size and position the image to fill the display screen (fill mode) or use the native aspect ratio of the input (follow mode). Using SIS commands or the OSD submenus, you can perform a one-time Auto-Image on the current input.

Only the horizontal and vertical positioning and the horizontal and vertical size are adjusted by the Auto-Image. All other controls are left unchanged.

• If the aspect ratio has been set to Fill, the H and V position returns to 0,0, and the H and V Size is set to match the current output rate.
• If the aspect ratio has been set to Follow, the H and V position and size are set to maintain the native aspect ratio of the input rate with respect to the current output resolution.

Auto-Image is useful in applications in which a variety of new input sources may be encountered (such as when a matrix switcher is connected). It is also useful for centering and sizing an image that has been adjusted out of default settings.

You can perform a one-time Auto-Image by the following methods:

• Front panel: While the OSD is not displayed, press the Auto-Image (▶) button twice. (The first press displays the message Press Auto to Confirm on the OSD. The second press initiates the Auto-Image.)
• OSD submenus: Select the Auto-Image / Press Enter to Auto-Image item from the Quick Setup Submenu (see page 17) or the Input Submenu (see page 22).
  • SIS commands (see the Auto-Image commands on page 48).

Changing the Output Resolution and Refresh Rate

In addition to the Output submenus (see pages 24 and 26), other options for setting the output resolution and refresh rate include resetting the output rate using the front panel ▼ button (see Resetting the Output Rate on page 36), SIS commands (see the Output Configuration commands beginning on page 53, and the PCS Configuration Program (see the program help file).

Custom Rates — DSC 3G-HD A Only

In addition to the 42 factory output resolutions, 3 custom user-defined rates are available for the DSC 3G-HD A via SIS commands (see the Output Scaler Rate commands on page 53 for the command format) or PCS (see the program help file). When no custom EDIDs are defined, these three resolutions and rates default to 720p @ 60 Hz. The OSD dynamically updates itself based on the current file stored in the custom EDID slot. For example, if a custom 720p EDID has been uploaded, the OSD would read C1: 720P @ 60 Hz.

Importing an HDMI EDID — DSC 3G-HD A Only

You can also import the EDID of a connected HDMI sink to use as a custom rate. This EDID can be saved and stored in one of three custom EDID slots, which are then available for custom EDID emulation or custom output rate generation (custom rate based on the EDIDs preferred timings) (see the Output EDID command on page 53).

NOTE: If an imported or custom rate is not a valid output resolution, the output reverts to the default (720p @ 60 Hz).

Changing the Output Resolution from the Front Panel — DSC HD-3G A Only

Depending on which Output LED is lit (2.97 Gbps for 3G-SDI, 1.485 Gbps for HD-SDI, or 270 Mbps for SD-SDI) you can press a combination of front panel buttons to cycle through the different levels of output signal format and change the resolution. This is helpful if you are not able to display an image on the screen.

To change the resolution using the front panel buttons:

1. With the scaler powered on, press and hold the Menu and Auto-Image (▶) buttons until the 1.485 Gbps (HD-SDI) LED lights (approximately 5 seconds), indicating that the unit is now outputting 720p @ 59.94 Hz. If a screen is connected, the following message is displayed:

Press Enter to confirm the new resolution. Unit will return to previous resolution in 15 seconds if not confirmed.

1. Press the ▲ or ▼ button repeatedly to cycle through the output resolutions typically associated with the HD-SDI output format.

NOTE: If you do not press a button within 15 seconds, the DSC reverts to the previous output rate and you must return to step 1 to select another resolution.

While the DSC is in resolution change mode, some of the front panel buttons have different functionality. The following table shows which buttons change function:

Front Panel Button Function
Menu	Cancel and exit. Returns to previous output resolution.
Enter	Confirm and exit. Sets the selected new resolution.
▲	Step through rates incrementally starting with 720p @ 59.94 Hz.
▼	Step through rates decrementally, starting with 720p @ 59.94 Hz.

1. To access more resolutions, continue pressing either arrow button. After you have stepped through the 1.485 Gbps resolutions, the unit moves to the next level (either the 270 Mbps or the 2.97 Gbps LED lights, depending on which arrow button you are pressing) and continues cycling through the available resolutions.

The following table shows the resolutions associated with each SDI signal type:

SDI Signal Type Resolutions
2.97 (3G-SDI) 1080p	@ 60 Hz
	1080p @ 59.94 Hz
	1080p @ 50 Hz
1.485 (HD-SDI) 1080i	@ 60 Hz
	1080i @ 59.94 Hz
	1080i @ 50 Hz
	720p @ 60 Hz
	720p @ 59.94 Hz
	720p @ 50 Hz
270 Mbps (SD-SDI) 480i @ 59.94 Hz

1. When you have arrived at the desired resolution, press Enter to confirm it.

Resetting the Output Rate

If an output image cannot be displayed due to an incompatible output rate, you can use the front panel buttons to toggle the output rate between 1024x768 @ 60 Hz and 720p @ 60 Hz for the DSC 3G-HD A or 1080i @ 59.94 Hz and 720p @ 59.94 Hz for the DSC HD-3G A.

To set the rate or toggle between the two available rates:

1. Ensure that the OSD is closed by pressing and holding Menu for 3 seconds.
2. Press and hold the ▼ button for approximately 5 seconds to toggle between the VESA and SMPTE rates (DSC 3G-HD A) or the 720p and 1080i rates (DSC HD-3G A).

NOTE: On the front panels, the ▼ button is labeled as follows:

• DSC 3G-HD A: Hold ▼ for XGA ↔ 720p.
• DSC HD-3G A: Hold ▼ for 720p ↔ 1080i.

Power Save Mode

In power save (standby) mode, all non-essential hardware is shut down in order to conserve power.

• To enable power save mode, enter the Power Save On SIS command (see the Power Save Mode commands on page 54).
• To exit power save mode, either enter the Power Save Off SIS command or press any front panel button. If the front panel is locked, this method does not work.

NOTE: The backup and restore functions available through the PCS control software are not accessible while the unit is in power save mode.

Presets

A preset is a set of input parameters that are either saved by you or automatically by the DSC as a files in DSC memory. Saved presets can be recalled and their settings implemented at any time. A preset saves time by enabling you to apply a group of settings to the DSC at one time.

The DSCs have three types of presets: Auto Memories, user presets, and global input presets.

Auto Memories

The DSC has 32 memory locations in which the current input configuration and picture control values are automatically stored as an input preset, when Auto Memory is enabled. An Auto Memory preset is recalled when an identical input resolution and rate is applied to the input.

Each Auto Memory preset is stored with a time stamp that is incremented each time its stored rate is detected. If all Auto Memory slots are occupied and a new rate is applied, the Auto Memory with the oldest time stamp is overwritten.

Auto memory can be enabled using the OSD (see the Auto Memory item of the Advanced submenu on page 32) and by SIS commands (see the Auto Memories commands on page 52).

The following information is stored in an Auto Memory preset:

• Contrast • Active lines (Vertical Active)
• Brightness • Horizontal image position
  • Detail • Vertical image position
  • Horizontal start • Horizontal image size (width)
  • Vertical start • Vertical image size (height)
  • Active pixels (Horizontal Active) • Total pixels

User Presets

Three memory slots are available for you to store certain input settings as a preset. You can then recall a saved preset and apply it to the current input.

NOTE: A user preset can be saved at one input resolution, then recalled at another.

User presets can be saved, recalled, and cleared via the OSD (see User Presets Submenu on page 19) or SIS commands (see the User Presets commands on page 52). The following values are saved in a user preset:

• Contrast • Active lines (Vertical Active)
• Brightness • Horizontal image position
  • Detail • Vertical image position
• Preset name • Horizontal image size (width)
  • Vertical start • Vertical image size (height)

NOTE: You can change the picture and image settings using the Picture Controls Submenu (see page 21) and Input Submenu (see page 22) or SIS commands (see the Presets commands on page 52). The preset name can be assigned only via SIS commands.

Input Presets

The DSC has 16 memory slots in which you can save input presets that are global to the HDMI or SDI input. These presets allow a matrix switcher with multiple types of video inputs (such as an Extron SMX) to be placed upstream from the DSC to expand the number of video sources. Input presets can be saved and recalled only through SIS commands (see the Input Presets commands on page 53).

Values for the following settings are saved in input presets:

• Contrast • Active pixels (Horizontal Active)
• Brightness • Active lines (Vertical Active)
  • Detail • Horizontal image position
• Film Mode • Vertical image position
• Audio gain and attenuation
• Horizontal image size (width)
  • Horizontal start • Vertical image size (height)
  • Vertical start • Total pixels

- Preset name

Saving a preset when using a matrix switcher

When using the DSC with a matrix switcher, do the following to save a preset:

1. Switch each input of the matrix to the input of the DSC.
2. Configure each input: size, position, detail, brightness, and contrast. (The remaining settings — horizontal start, vertical start, active pixels and lines, and total pixels — are not user-configurable, but are stored automatically as part of the preset.)
3. Save the settings to a preset for recall by the control system when that matrix input is routed to the HDMI or SDI input.

Locking the Front Panel (Executive Mode)

To prevent access by unauthorized users or accidental changes to the DSC settings, you can lock the front panel controls by placing the DSC in executive mode. In this mode, all front panel buttons are disabled and control is available only by SIS commands.

To lock the front panel, do either of the following:

• Press and hold the front panel Menu and ▼ buttons until the OSD displays the message Executive Mode Enabled (approximately 5 seconds). The message remains on the OSD approximately 2 seconds.
• Enter the Enable SIS command (see the Front Panel Lock (Executive Mode) commands on page 58).

To unlock the front panel, do either of the following:

• Press and hold the front panel Menu and ▼ buttons again until the OSD displays the message Executive Mode Disabled (approximately 5 seconds). The message remains on the OSD approximately 2 seconds.
• Enter the Disable SIS command (see the Front Panel Lock (Executive Mode) commands).

Resetting

Resetting the unit causes various settings to revert to the defaults that were set at the factory. Resets can be performed from the front panel buttons, the OSD, or SIS commands. The following resets are available:

• Factory defaults: This reset clears all user-specified settings but retains the latest firmware version. You can perform this reset by:
• Selecting Factory Reset from the Advanced submenu of the OSD (see the Factory Reset item on the Advanced submenu on page 32)
• Entering the Reset all device settings to factory default SIS command (see the Reset command on page 59)
  When the reset is complete, the message Factory Reset is displayed on the OSD.

- Factory firmware: This reset returns the unit to its factory default settings, including the original firmware with which it was shipped. All user settings are cleared.

To perform this reset, press and hold the Enter button for 20 seconds while applying power to the unit. When the reset is completed, the message Firmware Reset appears on the OSD.

NOTE: The Firmware Reset and Factory Reset messages are displayed for 1 minute after the reset to allow time for the display device to sync with the DSC output.

Remote Configuration and Control

This section describes the connections through which the DSC can be configured and controlled remotely via SIS commands and describes the commands that are available. It also provides the procedure for accessing the PCS configuration software. Topics include:

• SIS Commands
  • Product Configuration Software

SIS Commands

The DSC can be configured and controlled via a host computer or other device (such as a control system) attached to the front panel USB port or the rear panel RS-232 connector. Enter SIS commands using an application such as the Extron DataViewer, available at https://www.extron.com (see the DataViewer Help file to use this program).

For the RS-232 connection the scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control.

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the DSC determines that a command is valid, it executes the command and sends a response to the host device. All responses from the scaler to the host end with a carriage return and a line feed (CR/LF = 0) indicating the end of the response character string (one or more characters).

Copyright Information

The DSC sends the following copyright message upon connection to the host if the DSC is already connected via RS-232. (This message is displayed only with an RS-232 connection).

← (c) Copyright 20nn, Extron Electronics, DSC XX-XX A, Vn.nn, 60-130n-01

(20nn is the year, DSC XX-XX A is the model name, Vn.nn is the firmware version number, and 60-130n-01 is the unit part number.)

DSC-initiated Messages

When a local event such as a front panel selection or adjustment takes place, the DSC scaler responds by sending a message to the host. No response is required from the host. Example scaler-initiated messages are listed here.

- Reconfig

The DSC sends this response when a change in the input frequency is detected.

• Hplg0

The DSC 3G-HD A sends this response when a hot plug event on the output is detected (for example, when the unit is unplugged and reconnected).

Error Responses

When the DSC receives a valid command, it executes the command and sends a response to the host device. If the unit is unable to execute the command because the command contains invalid parameters, it returns one of the following error responses to the host.

E01 — Invalid input number
E06 — Invalid switch attempt in this mode
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid port number
E13 — Invalid parameter
E14 — Invalid command for this configuration
E17 — Invalid command for signal type
E22 — Busy

Using the Command and Response Table

The Command and Response Table for SIS Commands, beginning on page 48, lists the commands that the DSC scaler recognizes as valid, the responses that are returned to the host, a description of the command function or the results of executing the command, and an example of each command in ASCII.

NOTE: Unless otherwise stated, upper- and lowercase text can be used interchangeably in the commands.

3 = Verbose mode is on (enabled) and tagged responses are enabled and sent for queries.

NOTES:

- In verbose response mode, the DSC responds with more information than it usually would. For example, the DSC can send out a notice of a change in some setting without receiving a query via your PC. That change could have been a result of an internal process (a script execution), a selection made using a touchpanel or keypad, a change made using GV or a web page, or input from a connected sensor or switch.

That is an example of a verbose (wordy) relationship between the DSC and a connected device. Verbose mode creates more network traffic than usual, which can slow down network performance.

- If tagged responses are enabled, all read or view commands return the constant string plus the data. For example:

Command:

E\$NAV

Response: SsavM X40 (tagged mode)

or

X40 (untagged mode)

Mounting

This section contains information on mounting the DSC scaler. See

https://www.extron.com for available Extron mounting kits and ordering information. The DSC 3G-HD A and DSC HD-3G A scalers can be mounted by any of the methods described below. To mount the DSC using an Extron mounting kit, see the instructions provided with the kit.

Rack Mounting

Attach the DSC to a standard 19-inch rack shelf.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the DSC 3G-HD A or DSC HD-3G A in a rack.

CAUTION:

• Elevated operating ambient temperature — If the equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (TMA = +122 °F, +50 °C) specified by Extron.
• Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical loading — When mounting the equipment in the rack, ensure that uneven mechanical loading does not cause a hazardous condition.
• Circuit overloading — When connecting the equipment to the supply circuit, consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings when addressing this concern.
• Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

• Under-furniture mounting — Mount the DSC under the surface of a desk, table, or podium.
• Through-furniture mounting — Mount the DSC through a table or desk in which a hole has been cut to enable access to the front panel.

Free-standing

Attach the four rubber feet to the bottom of the DSC at the four corners and place the unit where desired.
