ON/OFF Switch and Flash Test Operation
-9-
To switch on the flashgun, slide the main switch to the "ON" position.
On the ready indicator "READY" lights up as soon as flash readiness is
established. Press the Test Button to ensure the flashgun works properly.
If the flashgun discharges, wait until the "READY" light glows again.
To switch off, slide the main switch to "OFF" position.
Illumination of LCD display
The LCD display is used to show general information about your camera and the current
status of the flashgun. Every time the "LIGHT" key is lightly tapped, the LCD
display will be illuminated for about 5 seconds.

-10-
• Automatic flash sync speed control
When the flashgun is ready, your camera will automatically switch it to the flash
sync speed from program mode or or to an aperture-priority mode selected.The sync
speed depends on the camera model and usually ranges between 1/30sec to 1/250sec.
When a flash shot has been taken, an "OK" symbol briefly flashes on the LCD display to confirm
correct exposure.
• Auto-focus "AF" measuring flash
The integrated "AF" red light beam of the flashgun supports the automatic focusing of auto-focus
TTL cameras.When the prevailing light is insufficient for automatic focusing, the flashgun will
project a red light beam onto the object as soon as the camera's shutter is lightly touched.The
camera's auto-focus system then focuses the object by this beam of red light.
• TTL flash control
When you switch on the flashgun, it will set at TTL mode first and the LCD display indicates "TTL".
When the Ready indicator lights up, press the shutter release fully to take the picture.The advanced
programming and computerized circuitry of the fllashgun provides the correct amount of flash light
output according to the camera's exposure measurement through the lens (TTL).
Taking a Picture AF / TTL Operation

-11-
Taking a Picture AF / TTL Operation
If you need to change the mode, simply press the mode selector.
For Canon type flashes, this flashgun's ETTL indicator will light while
connected with ETTL cameras.
For Nikon type flashes, this flashgun's LCD Display will show TTL, I-TTL
and BL in different ways while connected to different camera models.
Please refer to your camera's manual.
• Manual flash mode at full light output
To use the flashgun at full light output in the manual mode, the mode
selector must be set to the M (Manual) position.The LCD display
indicates M (Manual). A full-power flash will then be fired each time
the flashgun is triggered.The LCD display automatically shows the
flash-to-subject distance required for a correct exposure.
An adaptation to the individual shooting situation can be achieved by
changing the lens diaphragm or the focal length (on the camera). 5
level "Power Ratios" of 1/1, 1/2, 1/4, 1/8 and 1/16 could be selected by
slightly tapping the Mode selector when it is at the manual position.
For Nikon D40 and D40X owners:The flash can support an ISO speed
up to 800 in full auto mode. It may not perform as expected at higher
speeds.

Front and Rear Curtain Synchronization
-12-
Front and rear curtain synchronization is supported, to use simply set into Front or Rear mode
when using.
For Pentax, you could select the synchronization mode as front curtain ( ) or rear curtain
( ).The flashgun will fire according to the mode selected to match with the camera shutter.
Canon, Sony Alpha, Konica Minolta, Nikon, Olympus and Panasonic cameras control front or
rear-curtain synchronization, therefore settings for the flashgun are not required.
Note:The rear curtain synchronization is only possible on cameras with this feature.
See your camera’s instruction manual for details.

Bounced and Swiveled Flash
-13-
Photos shot with full frontal flash are easily recognized by their
harsh, dense shadows.This is often associated with a sharp drop of
the foreground to the background.This phenomenon can be
avoided with bounced and swiveled flashes. Diffused light will
produce a soft and uniform shadow when the reflector is turned
vertically at a 90º angle. Select white or reflective surfaces to
bounce the light off. Otherwise your pictures will come with an
unnatural color cast similar to that of the reflecting surface.When
swiveling the reflector ensure that no direct light from the reflector
reaches the subject. When using bouncing or swiveling flash, the zooming position will be
locked in 50mm, except with Manual mode.
• Reflecting plate and diffuser
The flashgun has a built-in reflecting plate and diffuser.You can slide out the reflecting
plate or diffuser from the top of the flash head. Bouncing the flash head and using the
reflecting plate can produce better looking pictures.The diffuser can reduce
strong light to create soft effects.

Power Zooming
-14-
• Automatic motor zoom control
If you are using a zoom lens, which transmit its focal length to the
camera, the camera will pass on this information to the flashgun.
The flashgun then automatically adjusts its zoom position to comply
with the focal length of the lens. Automatic motor zooming reflector
control is only possible with cameras permitting digital data
transmission to the flalshgun.
The LC D display on the flashgun indicates zooming positions of 24-28-35-50-70-85mm.
When the flashgun is switched on, the activated zoom position is set at 35mm. As soon
as the camera's shutter is lightly touched, the focal length of the flashgun is
automatically adapted to the focal length of the lens.
Whenever the flash head is not at a normal position (facing to the front), such as in bounced or
swiveled at different positions, the zoom position will be at 50mm as indicated by the LCD
display with a brief flash in auto mode.

Manual Motor Zoom Control
-15-
The "Zoom" key permits you to change the zoom reflector's
position independently of the focal length of the lens.The LCD
display then indicates "M" and adjusts the zoom position of the
reflector.
By slightly tapping the "Zoom" key you can select the zoom
position in the following sequence: 24-28-35-50-70-85mm.

This flashgun can perform as a wireless slave by switching the Slave Mode Switch to S position.The
flashgun will automatically switch to M mode with power ratio 1:1.When the sensor detects the
external flash fire, the flash will synchronize to the fire.The amount of light output can be controlled
by selecting the power ratio from 1/1 to 1/16. If multiple flashes are set as slaves, you must consider
the light amount to get the correct exposure. When the slave mode is on, the power saving mode will
not function.
Power Saving Function
The flashgun will automatically be switched to power saving mode 3 minutes after:
• the flashgun was switched on
• the last flash was fired
The LCD Display will show an "OFF" signal.To reactivate the flashgun, simply press any
buttons underneath the LCD display panel or switch the main switch off and on again.
The flashgun is not completely switched off, however its power consumption is
drastically reduced. If you are not going to use your flashgun any longer, set the main
switch to "OFF" -16-
