In S2 mode, the flash will ignore a single “preflash” from the master flash and will only fire in response to
the second, actual flash from the master.
6. Modeling Lamp On / Off
This flash head is equipped with LED modeling lamp.
To turn the modeling lamp on or off, press the Modeling Lamp Switch (12). When it lights up, will be
shown on the LCD display.
The modeling lamp will be off automatically after 15 minutes so as to prevent overheating. Allow a rest
time of 5 minutes before you turn it on.
7. Sound Prompt Beep
The battery pack is built in with a buzzer to prompt you that the flash kit is ready for firing. You can press
the Buzz Button (11) to enable or disable the sound prompt beep.
When the buzzer is enabled, will be shown on the LCD display.
8. Wireless Control Function
The battery pack is built in with a Wireless Control Port (16) so that you can wirelessly control the flash
kit in terms of power level, modeling lamp & buzzer on/off and achieve flash triggering.
To control the flash kit wirelessly, the included CL-Tx/Rx flash trigger is required. Insert its receive end
into the Wireless Control Port (16) on the battery pack and mount the transmit end onto the camera
hotshoe. Settings made on the hotshoe-mounted transmit and receive ends will be wirelessly
communicated to the flash and battery pack. Then you can press the camera shutter button to trigger the
flash. Also, you can hold the transmit end in your hand to achieve wireless control.
When the battery pack receives wireless signals, will be shown on the LCD display.
For full instructions on the use of CL-Tx/Rx flash trigger, see its user manual.
9. Sync Triggering
The Sync Cord Jack (15) is a φ3.5mm plug. Insert a trigger plug
here and the flash will be fired
synchronously with the camera shutter.
1. Over-Temperature Protection
To avoid overheating and deteriorating the flash head, DO NOT fire more than 100 continuous flashes in
fast succession at 1/1 full power. After 100 continuous flashes, allow a rest time of at least 10 minutes.
If you fire more than 100 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 kit will then return to normal.
When the over-temperature protection is started, will be shown on the LCD display.
