Frequently Asked Questions - ATW-1701P1 Audio-Technica

How do I pair the transmitter with the receiver?

Turn on the receiver and transmitter. Press the System ID button on the receiver to select an ID (1-8). Within 15 seconds, press and hold the Pair button on the receiver for about 1 second until the Pair light blinks green. Then, within 30 seconds, press and hold the Pair button on the transmitter. The receiver's Pair light will glow steady when pairing is successful.

What is the operating range of the ATW-1701P1?

The typical operating range is 30 meters (100 feet) radius, or 60 meters (200 feet) diameter in an open environment with no interfering signals. Actual range may vary due to obstacles or interference.

How long does the receiver battery last and how do I charge it?

The receiver's internal Li-ion battery lasts up to 12 hours depending on conditions. Charge it using the supplied AC adapter and USB cable. Connect the USB cable to the receiver's USB Power Input and plug the adapter into an AC outlet. The Power/Battery indicator glows red during charging and green when fully charged. Full charge takes about 4.5 hours.

Can I use multiple ATW-1701P1 systems together?

Yes, up to eight channels (transmitters) can be used simultaneously without frequency coordination issues. Each receiver-transmitter pair must be assigned a unique System ID number (1-8). Follow the pairing procedure for each transmitter.

What type of batteries does the transmitter use?

The body-pack (ATW-T1001) and handheld (ATW-T1002) transmitters both use two AA alkaline batteries (not included). Battery life is typically over 7 hours with alkaline batteries. Rechargeable AA batteries can also be used.

How do I adjust the audio level on the transmitter?

For the body-pack transmitter, slide off the battery cover and use the supplied screwdriver to turn the 'VOL' control. For the handheld, unscrew the lower body cover and adjust the 'LEVEL' control. Turn clockwise to increase gain; adjust so the AF Peak indicator on the receiver does not light at maximum input.

What does the mute function do?

Pressing the Power/Mute button on the transmitter toggles between muted (red LED) and unmuted (green LED). When muted, the transmitter still emits RF but no audio. Mute lock can be activated by pressing Pair then Power while off.

How do I mount the receiver to my camera?

Slide the camera shoe mount onto the receiver from the rear until it clicks. Then slide the mount bracket into the camera's hot shoe and tighten the nut. The bracket also has a 1/4-inch socket for tripod mounting.

What should I do if the receiver's Power/Battery indicator flashes green?

This indicates the receiver's battery needs charging. Connect the AC adapter and USB cable to charge the internal battery. While charging, the indicator glows red; it turns green when fully charged.

How do I clear a paired System ID?

To clear an individual ID, press the System ID button to select the blinking ID, then press and hold both Pair and ID buttons for about 3 seconds until 'o' appears. To clear all pairings, press and hold Pair and ID for 3 seconds to get 'o', then release and press and hold again for 3 seconds until 'A' appears.

RISK OF ELECTRIC SHOCK

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT REMOVE SCREWS. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THE APPLIANCE TO RAIN OR MOISTURE.

CERTIFICATION: THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. THIS DEVICE COMPLIES WITH INDUSTRY CANADA LICENSE-EXEMPT RSS STANDARDISI. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESired OPERATION.

WARNING: Changes or modifications not expressly approved in writing by Audio-Technica may void the user's authority to operate this equipment.

RF Exposure Statement: This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.

The ATW-R1 700 complies with FCC/C radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the IC radio frequency (RF) Exposure rules. This equipment has very low levels of RF energy that it deemed to comply without maximum permissive exposure evaluation. (MPE). But it is desirable that it should be installed and operated keeping the radiator at least 20cm or more away from person's body.

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RFI in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects cause no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur but such findings have not been confirmed by additional research. ATW-T1001, ATW-T1002 has been tested and found to comply with FCC/IC radiation exposure limits set fourth for an uncontrolled environment and meets the FCC radio frequency (RFI) Exposure Guidelines and RSS-102 of the IC radio frequency (RFI) Exposure rules.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing to qualified service personnel. No user/serviceable parts inside. Do not expose to rain or moisture. The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compliance with federal regulations. Do not attempt to open the receiver or transmitter. To do so will void the warranty, and may cause improper operation.

Danger of explosion if battery is replaced incorrectly. If battery dies, send receiver to Audio-Technica or other qualified service center so battery can be replaced with same or equivalent type. Likewise, send damaged, inoperable receivers to Audio-Technica or other qualified service center for recycling—do not throw away receiver as its battery contains toxic materials.

Notice to individuals with implanted cardiac pacemakers or AICD devices: Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All

wireless microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difficulty, especially if they are at least a few inches away. However, since a "body-pack" mic transmitter typically is placed against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent to the medical device. Note also that any medical-device disruption will cease when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any problems with the use of this or any other RF equipment.

Thank you for choosing an Audio-Technica professional wireless system. You have joined thousands of other satisfied customers who have chosen our products because of their quality, performance and reliability. This wireless microphone system is the successful result of years of design and manufacturing experience.

Audio-Technica's System 10 Portable Camera-Mount is a digital wireless system designed to provide rock-solid performance along with easy setup and clear, natural sound quality. Featuring a compact design, System 10 Portable Camera-Mount is available in handheld, lavalier and body-pack configurations. Operating in the 2.4 GHz range, far from TV and DTV interference, System 10 Portable Camera-Mount offers extremely easy operation and instantaneous channel selection. Up to eight channels may be used together without any frequency coordination problems or group selection issues.

System 10 wireless ensures clear communications by providing three levels of diversity assurance: frequency, time, and space. Frequency Diversity sends the signal on two dynamically allocated frequencies for interference-free communication. Time Diversity sends the signal in multiple time slots to maximize immunity to multipath interference. Finally, Space Diversity uses two antennas on each transmitter and receiver to maximize signal integrity.

Each System 10 professional digital wireless system includes a receiver and camera shoe mount, and either a body-pack transmitter or a handheld microphone/transmitter.

Because System 10 packaging is designed to hold all versions of the system, some compartments in the carton may be intentionally left empty.

The ATW-R1700 receiver includes a switching power supply that automatically adapts to changes in mains voltage.

The versatile ATW-T1001 UniPal® body-pack transmitter has both a high-impedance input for instruments, and a low-impedance input with bias connection for use with dynamic and electret condenser microphones. The ATW-T1002 handheld transmitter features a unidirectional dynamic microphone element.

Both the body-pack and handheld transmitters use internal AA batteries and have Power/Mute switches and input Trim (level) adjustments.

Receiver Installation

Location

For best operation the receiver should be at least 3' (1 m) above the ground and at least 3' (1 m) away from a wall or metal surface to minimize reflections. Keep the receiver antennas away from noise sources such as other digital wireless equipment, microwave ovens, as well as away from large metal objects. Keep System 10 receiver 30' (9 m) away from wireless access points. In multi-channel systems, position receivers at least 3' (1 m) apart and keep operating transmitters at least 6' (2 m) from the receivers to help assure maximum RF performance.

Output Connection

The ATW-R1700 has a single audio output jack that accepts the 3.5 mm ( ^1/_8 ) cable included in the package.

Use the Audio Output Selector Switch to choose between a balanced and an unbalanced dual mono signal.

The 3.5 mm (1/8") Headphone Monitor output works with mono or stereo headphones (the output sends a dual mono audio signal to stereo headphones). Use the Headphone Level Control to adjust the volume.

Power Connection

NOTE: Use only the supplied AC adapter and power cord to power or charge receiver. To use AC power, connect the power cord's USB A-type male port to the AC adapter and connect the Micro-USB B port to the USB Power Input on the side of the receiver. Next, plug the adapter into a standard 120 Volt 60 Hz or 230 volt 50 Hz (depending on global location) AC power outlet. The AC adapter and USB cable also charges the receiver's internal battery. Charge battery in an environment with moderate temperature (41°F - 95°F). The system will not charge in temperatures below 32°F or above 104°F in order to prevent potential damage to battery. For safety and to conserve energy, unplug the AC adapter from the AC outlet when the system is not in use. Store receiver in a cool place.

Antennas

For best reception, position the removable antennas in the shape of a "V" so that both tilt 45°.

System Operation

Turn down the headphone volume control and the camera/mixer level before starting up the wireless system. Do not switch on the transmitter yet.

Receiver on...

Press and hold receiver power button to turn receiver on. Power/Battery indicator will glow green and the blue System ID number on the front panel will illuminate.

If the Power/Battery indicator flashes green, the receiver's battery needs to be charged. You can charge the battery with the supplied AC adapter and USB cable, following the instructions under Power Connection on page 3. The LCD RX Battery Gauge will blink during charging and a lightning bolt symbol will appear to the right of "RX." The Power/Battery indicator will glow red while the battery is charging and turn green when charging is complete. Audio-Technica recommends fully charging the internal battery before using the receiver for the first time. Average charge time takes 4 hours 30 minutes. To help maintain the battery, it is best to operate the receiver (at least occasionally) without the AC power supply and recharge when needed. Also, avoid storing a fully charged receiver for a long period of time.

Transmitter on...

When the transmitter is switched on, the receiver's green pair indicator will light, and two indicators light on the transmitter: the transmitter Power / Battery / Mute status indicator will glow green; and the transmitter blue System ID display will illuminate. The blue System ID display on the transmitter and receiver turns off after 30 seconds to conserve battery power; the transmitter Power / Battery / Mute status indicator will remain illuminated, indicating transmitter status.

To re-illuminate System ID display, press the Power / Mute switch.

Note: this will alter the transmitter mute status. A slight touch of the power switch toggles between muted and unmuted operation.

The transmitter's Power / Battery / Mute status indicator glows red when transmitter is muted, or green to indicate unmuted status. In a low-battery situation, the Power / Battery / Mute status indicator begins to blink.

The transmitters have a soft-touch power switch. When the switch is set to "Mute" (red indicator LED), the transmitter produces RF with no audio signal. When the switch is "On" (green indicator LED) the transmitter produces both RF and audio. Excessive audio input to the transmitter will cause the receiver's red AF Peak indicator to light.

Receiver Attenuator

Typically, the receiver Audio Output Attenuator switch should be set at 0dB, and the overall gain should be adjusted from the camera. If a camera lacks that capability or if sensitivity is too high, use the Audio Output Attenuator switch to reduce the gain until the signal does not distort.

Input Level Adjustment

Input trimmer controls in the transmitters enable you to maximize performance for a particular microphone or guitar sensitivity, or to adjust for different acoustic input levels.

Adjusting Input Level — UniPak ^® Transmitter

Slide the battery cover off the transmitter and remove the screwdriver from its clip. Using the screwdriver, gently turn the "VOL" (Volume – Microphone/Instrument Level) all the way up (clockwise, toward "H"). Check for excessive gain by speaking / singing into the microphone at typically loud levels while watching the receiver's

Peak Indicator. If the Peak indicator does light, turn the "VOL" control slightly counterclockwise until the Peak indicator no longer lights with maximum audio input to the transmitter.

Adjusting Input Level — Handheld Transmitter

Unscrew the lower body cover and slide it off, exposing the screwdriver and "LEVEL" (Gain Trimmer) control (Fig. C). Remove the screwdriver from its clip. Gently turn the "LEVEL" control to its full clockwise position (toward the side marked "H"), the factory setting. Check for excessive gain by speaking/singing into the microphone at typically loud levels while watching the receiver's AF Peak indicator. If the AF Peak indicator does light, turn the "LEVEL" control slightly counterclockwise until the AF Peak indicator no longer lights with maximum audio input to the mic/transmitter.

Return the screwdriver to its clip and close and secure the lower body. No further transmitter gain adjustments should be needed, as long as the acoustic input does not change significantly.

CAUTION! The small trimmer controls are delicate; use only the supplied screwdriver. Do not force the trimmers beyond their normal 190^ range of rotation.

Return the screwdriver to its storage clip when not in use.

Setting System ID Number & Pairing your Transmitter and Receiver

Your system has been preconfigured at the factory to operate with no other pairing setup required; it will work out of the box. That is, your receiver and transmitter are already a digital pair, and they have been assigned the same System ID number.

The pairing instructions outlined below will help you if you find it necessary to change system ID numbers in multiple-system configurations, or pair a new transmitter to an existing receiver.

NOTE: System ID is an identical number assigned to a paired receiver and transmitter for identification purposes. The System ID number is not related to transmitting frequency. Due to the dynamic nature of System 10 automatic frequency selection, the actual transmitting frequencies may change during power-up or performance. These frequency changes are seamless and imperceptible to the ear.

Pairing Receiver with Transmitters

Note: Up to eight transmitters may be paired with the receiver.

1. Turn the receiver and first transmitter on.

2. Press the System ID button on the receiver to choose an ID number from 1 to 8. The receiver's display will show your new ID and begin to blink.

3. Within 15 seconds, press and hold the Pair button on the receiver for about one second. The Pair light will begin to blink green. The receiver is now in Pair Mode.

Note: If the receiver Pair button is not pressed within 15 seconds, the system ID number will revert to its previous setting.

1. Open the transmitter and press and hold its Pair button within 30 seconds of entering Pair Mode. The transmitter display will now show the System ID number you have chosen on the receiver. The receiver's Pair light will glow steady, indicating you have successfully paired your system.

2. To pair an additional transmitter, you must switch off first transmitter by pressing and holding its Power/Mute button. Turn the second transmitter on and follow instructions 2-4 above, making sure to assign a different System ID number to the new transmitter.

3. Repeat for each additional transmitter. Remember to switch off all transmitters already paired before adding a new one and to use a unique ID number for each transmitter.

Note: With all transmitters turned off, the receiver's System ID Display will cycle through all currently paired ID numbers. Turn on a transmitter to activate its pairing with the receiver. The receiver recognizes only one transmitter at a time. That transmitter must be turned off before the receiver will recognize another paired transmitter. *If that transmitter is turned off out of range, the receiver will not recognize another paired transmitter until the receiver is reset by disconnecting the power supply.

Clearing Individual ID Pairings

1. Press the receiver's System ID button to select the ID number you wish to clear. The number will begin to blink.
2. Press and hold the Pair and then ID button for about three seconds, until the display shows a blinking "o." This indicates that your selected ID number has been cleared.
3. Release the Pair and ID buttons and, after a few seconds, the display will stop blinking and return to normal operation.
4. Repeat to clear additional ID pairings.

Clearing All ID Pairings

1. Press and hold the receiver's Pair and then ID button for about three seconds, until the display shows a blinking "o."
2. Release the Pair and ID buttons. Then, within three seconds, press and hold the Pair and ID buttons again, until the display shows a blinking "A." This indicates that all your paired ID numbers have been cleared.
3. After blinking three seconds, the "A" will change to "-" to indicate that there are no paired transmitters.

Ten Tips to Obtain the Best Results

1. Use only fresh alkaline or fully charged replaceable batteries for the transmitter.

2. Position the receiver so that it has the fewest possible obstructions between it and the normal location of the transmitter. Line-of-sight is best.

3. The transmitter and the receiver should be as close together as conveniently possible, but not less than 6' (2 m).

4. While System 10 has been designed to conveniently mount on cameras, please keep other wireless devices (including wireless systems and routers) away from System 10 receivers. For best performance, some routers and Wi-Fi-based wireless systems may need to be up to 30 feet away from System 10 receivers.
5. The receiver antennas should be kept away from any metal.
6. Use the transmitter level control to optimize performance for your sound source.
7. If the receiver output is set too low, the overall signal-to-noise ratio of the system may be reduced. Conversely, if the Attenuator of the receiver is set too high, it may over-drive the input of the camera/mixer, causing distortion. Adjust the output level of the receiver so the highest sound pressure level going into the camera/mixer causes no input overload, and yet permits the camera/mixer level controls to operate in their "normal" range (not set too high or too low). This provides the optimum signal-to-noise for the entire system.
8. Turn the transmitter off when not in use. Remove the battery if the transmitter is not to be used for a period of time.
9. Unplug the receiver from the AC outlet when the system is not in use.

System Operating Frequencies

Automatic Frequency Selection

System 10 wireless systems operate in automatically selected frequencies in the 2.4 GHz range, far from TV and DTV interference. Up to eight channels may be used together without any frequency coordination problems or group selection issues. Every time a receiver/transmitter pair is powered on, it automatically selects clear frequencies. Due to the dynamic nature of System 10 automatic frequency selection, these transmitting frequencies may change during power-up or performance if interference is encountered. These frequency changes occur at both the receiver and transmitter; they are seamless and imperceptible to the ear.
