To conserve battery power, the flash unit will automatically turn to standby mode when the flash is not used for approximate 3 minutes. To on the flash again, either press the flash test button (10) or switch off and on again using the ON/OFF switch. When the flash is not in use for extended period of time, slide the ON/OFF switch to the off position.

EXPOSURE/DISTANCE TABLE\*

This is a guide table showing the maximum effective range based on different combination of ISO, zoom lens and aperture setting. Base on the ISO window (11), setting the ISO setting knob (5) according to the ISO and zoom head position will show the maximum effective TTL range of the flash unit.

For example, at ISO 100 set at zoom position 50mm, the effective TTL range, according to 5 different Fristop setting is listed out as follows:

F/stop Maximum Effective TTL Range (ISO 100)

F2.0 17m / 56ft

F2.8 12m / 40ft

F4.0 8.5m / 28ft

F5.6 6.0m / 20ft

F8.0 4.3m / 14ft

*For Canon and Nikon only

USING THE AUTO CHECK LAMP

The green auto check lamp (14) located at the back of the flash is used to ensure that your subject is within the effective TTL range of the flash unit. When the ready lamp (13) is on, press the camera shutter release button to fire the flash. If your subject is within the effective TTL range, the green auto check lamp will illuminate for approximate 2 seconds indicating correct flash exposure has been obtained. If the green auto check lamp does not illuminate, it meant that the subject is not within the effective range. In this situation, move closer to the subject and try again.

FLASH MODE SWITCH SELECTION (For Nikon only)

The flash mode switch (16) is used to select between automatic balanced i-TTL flash mode (BL) and standard i-TTL mode (STD). Regardless of the flash mode selected, preflashes are fired by the flash and reflected to the camera auto flash sensor, after which the camera will automatically control the flash output for correct exposure.

AUTOMATIC BALANCED (BL) i-TTL mode

When this mode is selected, preflash will first be fired to determine the subject and background lighting. The flash output will then be automatic adjusted for a perfect balanced exposure lighting between the subject and the background.

STANDARD (STD) i-TTL mode

When this mode is selected, preflash will first be fired to determine the subject lighting. The flash output will then be automatically adjusted to ensure that the main subject is sufficiently exposed regardless of the background lighting. This mode is mainly used for long distance photography and often produce well illuminated subject. This mode is particularly useful when there is strong background lighting which may render underexposed subject when BL mode is being used.

PROGAM TTL MODE

Program TTL mode is one of the most popular and easy way of using Digital SLR cameras.

This flash unit provide full automatic TTL(Through the lens) control of flash exposure when used on dedicated model with inbuilt hotshoe dedication which provides the ETTL/TTL (for Canon) or i-TTL (for Nikon) auto flash metering features (Please refer to your camera owner's manual).

When using the flash unit outdoor under sunlight, the flash will automatically reduce its output to properly illuminate the subject. To use this flash unit in program mode, set your camera to 'P' (Program) mode or 'Auto' mode.

Once the camera is set to any of the above 2 modes, the flash unit will automatically fire the correct exposure to properly illuminate the main subject and background. This TTL dedicated mode can be used on practically any situation ranging from total darkness to daylight/ambient light.

Below are the steps that you need to follow to use the flash unit in program TTL mode:

1. Set the camera to P or Auto mode.

2. Slide the ON/OFF switch to the ON position.

3. For Canon: If the camera body supports E-TTL, the E-TTL indicator (16) will light up; For Nikon: Select the flash mode (16) (Automatic Balance iTTL or Standard iTTL)*.

4. Check that distance to the subject is within the effective TTL range as indicated on the exposure/distance table.

5. Focus on the subject

6. Press the shutter button fully to take the picture after ensuring that the ready lamp is on. When the flash is fully charged, the flash indicator will also be lit in the camera viewfinder.

7. To confirm that the flash unit fires the correct exposure, the Green autocheck lamp will light up for approximate 2 seconds. In the event that the green lamp does not lit, retake the picture at a closer distance

* -Depends on your camera body. Check your owner manual for availability of Automatic Balanced or Standard i-TTL features.

Auto TTL Mode

This flash unit can also be used with the camera set at any of the preset program mode (AV-Aperture priority, TV-Shutter Speed priority, Manual Exposure).

AV Aperture Priority Mode

This mode permits you to set the aperture value manually while the shutter speed will be automatically set by the camera. When using this mode, the flash exposure will be automatic controlled by the camera base on the corbination of shutter speed, aperture value and the flash mode (16) selected on the flash unit.

TV Speed Priority Mode

This mode permits you to select your desired shutter speed* and the aperture value will be automatically selected by the camera. When using this mode, the flash exposure will be automatically controlled by the camera based on the combination of shutter speed, aperture value and the flash mode (16)selected on the flash unit.

*Check with your camera manual for the maximum flash synchronization speed.

Manual Mode

This mode permits you to manually select your desired shutter speed and the aperture value. When using this mode, them flash exposure will be automatically controlled by the camera base d on the combination of shutter speed, aperture value and the flash mode (18) selected on the flash unit.

USING THE ZOOM HEAD

For wide angle picture taken at 28mm, set the zoom head position of the flash unit to 28mm or 35mm (35mm equivalent) depending on the zoom position of the lens*. This will help to ensure that the angle of lens coverage is adequately illuminated by the flash unit.

For telephoto pictures taken at 85mm and above (35mm equivalent), set the zoom head position to 85mm on the flash unit.

*Note: For Canon Digital 5LR cameras, the lens conversion factor to 35mm equivalent is usually 1.6x of the range indicated on the camera lens. For example, a zoom range of 18-55mm, when converted into 35mm equivalent is approximate 29 - 80mm.

*Note: For Nikon Digital SLR cameras, the lens conversion factor to 35mm equivalent is usually 1.5x of the range indicated on the camera lens. For example, AF-S Nikkor 18-55mm ED lens, when converted into 35mm equivalent is approximate 27 - 82.5mm.

USING THE BOUNCE AND SWIVEL HEAD

When using a direct flash on the subject, pictures taken will either result in excessive shadow being formed behind the subject or that the subject will be slightly over illuminated even though flash control is automatic.

To resolve the above two issues, you can use different combination of bounce head position ranging from 0-90 degree as well as the swivel feature from 0-330 degree. In this way, you can eliminate the shadow issues as well as produce more natural pictures.

For best results, it is recommended to bounce/swivel off white walls or ceiling with the zoom head set at the 50mm position. To ensure correct flash exposure, check that the green auto check lamp lit after taking the picture.

*Note that the maximum flash distance is reduce considerably because light travel indirectly to the subject over an increased distance and will usually lose 2-3 aperture of light (listops) even though the reflection surface is white. The bounce and swivel head must be adjusted properly to achieve the best possible lighting effect.
