Protection
To avoid overheating and deteriorating the flash head, do not fire more than 40
continuous flashes in fast succession at 1/1 full power. After 40 continuous flashes, allow a
rest time of at least 10 minutes.
If you fire more than 40 continuous flashes and then fire more flashes in short intervals,
the inner over-temperature protection function may be activated and make the recycling
time about 10 to 15 seconds. If this occurs, allow a rest time of about 10 minutes, and the
flash unit will then return to normal.
When the over-temperature protection is started, is shown on the LCD display.

Hi-Speed Sync Triggering
To enter mode, press both Mode Selection Button (16) and LED Light Control Button(14).
Press Mode Selection Button (16) again to exit mode.
In hi-speed sync triggering mode, you can use a hi-speed sync trigger to have your flash
unit synchronize with all shutter speeds of cameras
(max. 1/8000 second, up to your
camera). This is convenient when you want to use aperture- priority for fill-flash portraits.
Note:
Hi-speed sync triggering mode is effective only when the flash unit is used
together with
hi-speed sync trigger, e.g.,
PIXAPRO
Pro ST-II
transceiver.
Hi-speed sync triggering mode is not available when the flash unit is mounted onto the
camera hotshoe.

9. Buzz Function
The buzz function can be controlled by pressing BUZZ Button (15).
When the buzzer is turned on, is shown on the LCD display.
10. Wireless Control Function
The flash unit is built in with a Wireless Control Port (9) so that you can wirelessly control
the on-and-off of your flash, modeling lamp and buzzer, as well as adjust the flash output
level, etc.
To control the flash wirelessly, you need a
PIXAPRO
Pro AC
series remote control set
(on-
camera and on-flash transceiver). Insert its receive end into the Wireless Control
Port (9)
on the flash and insert the transmit end into the camera hot shoe. Settings made on the
hotshoe-mounted transceiver and receive ends will be wirelessly communicated to the
flash. Then you can press the camera shutter-release button to trigger the flash.
For full instructions on the use of
Pro AC
series remote control, see its user manual.
When the flash unit receives wireless signals, is shown on the LCD display.
11. Sync Triggering
The Sync Cord Jack (10) is a
Φ
3.5mm plug. Insert a trigger plug here and the flash will be
fired synchronously with the camera shutter.
12. PC Sync Triggering
Insert one end of a PC sync cable into the PC Sync Socket (11) of the flash unit and the
other end into the PC Sync Socket on the camera. The flash unit will fire when the camera’s
shutter-release button is pressed.
