Operating Your Flash and Running a Test Flash
Slide the ON/OFF switch to the "ON" position. After a few seconds
the Test/Ready lamp should illuminate, indicating that the flash is
ready to use. Press the Test/Ready button to make sure that your
flash works properly. If the flash discharges, it should be working
properly. Wait until the Ready lamp glows again to use once more.
Adjust your camera to the appropriate setting. Most cameras should
be set to the program position (see your camera's manual for details
on flash synchronization.) When the flash is ready to fire, it will
automatically match the camera's shutter speed. The flash readiness
indicator will appear on the camera. Different camera models indicate
flash readiness in different ways (see your camera's manual).
Point the digital camera at the subject and focus. Press the shutter
button on the digital camera half way down to check the image. Then
press the shutter button all the way down firmly. The Auto OK
indicator will light when the picture is exposed correctly.

AF/TTL Operation
AF - AUTO FOCUS
If the camera is compatible with an external AF mode, when the shutter button is pressed
half way down, the focus assist light is automatically activated to help the camera focus
properly when the subject is in darkness.
TTL
The flash performs pre-flashes for cameras to calculate the intensity of flash light output.
Therefore the flash light output is controlled automatically.
-For Nikon D40 & D40x owners: The flash can support an ISO speed up to 800 in full auto
mode. It may not perform as expected if the ISO speed exceeds the supported range.
Red-Eye Reduction (Type NIK, OLY, PANA and PEN)
The red-eye reduction function reduces any red-eye problems by emitting pre-flashes
before the main flash. To setup this function, please refer to your camera’s instruction
manual.

Front and Rear Curtain Synchronization
Some cameras offer the option of rear curtain synchronization (Rear mode) triggering the
flash unit at the end of the exposure time. Rear curtain synchronization is particularly
advantageous when using slow shutter speeds (slower than 1/30 sec.) or when shooting
moving objects that have their own source of light. Rear curtain synchronization gives a
more realistic impression of movement because the light streaks behind the light source
instead of building up in front of it, as is the case when the flash is synchronized with the
front shutter curtain. Depending on its operation mode, the camera uses shutter speeds
slower than its sync speed.
For Type PEN flash: You could select the synchronization mode as either front curtain (
)
or rear curtain (
) at the back of the flash. The flash will fire according to the mode
selected to match with the camera shutter.
For Type CAN, NIK, OLY, PANA, SON flashes: The camera controls front or rear curtain
synchronization, therefore no setting is required to be changed on the flash.
Note: The rear curtain synchronization is only possible on cameras with this feature. See
your camera’s instruction manual for details.

Bounce Photography
Using direct a flash to illuminate a subject will result in harsh,
unnatural and unattractive shadows. This can be avoided by
using bounce flash. The head of your flash can be tilted to an
angle of 45°, 60°, 75°, or 90°. You can tilt the flash head to
bounce the light off the ceiling or walls. While shooting indoors,
this technique can help to create more natural looking pictures
of people with softer shadows.
In order to have your pictures correctly exposed using bounce
flash, it is recommended to follow the steps below:
(1) 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.
(2) Set the camera’s exposure mode to Aperture Priority Auto (“A”) or Manual (“M”).
(3) Use a wider aperture than normal, as 2 or 3 stops of light can be lost when using
bounce flash.

Power Saving Functions
If there is no communication between the flash and your camera for about three minutes,
the flash will automatically be switched to power saving mode in order save battery power.
-The Ready light will be off while in power saving mode.
-To reactivate the flashgun, simply press your camera’s shutter button or switch the main
switch off and on again.
-The flashgun is not completely switched off in power saving mode. However, power
consumption is drastically reduced. If you are not going to use your flashgun for a while,
we recommend you to turn the flash off.

Maintenance and Tips for Taking Better Photos
• When not in use, switch the unit off. Take the
batteries out when the flash is being stored or when it
will be carried for a long time. Keep your flash away
from dust and moisture to prolong its life.
• The flash should not be exposed to moisture or
liquids.
• Batteries should not be exposed to excessive heat
from sunshine, fire or the like.
• Never try to open or repair your flash since the
electronic circuit inside carries a high voltage. If your
flash needs repair or does not work properly, please
contact a qualified repair service.
