 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.
