Audio Button
When the LED indicator over the audio button is on, the monolight will emit a
beep to indicate various alerts and functions. To turn this function off, press the
audio button once. The LED indicator will turn off. Press the audio button again
to reactivate the function.
Note: When the audio function is disabled, the modeling light will act as a
recycle indiactor. When the flash is fired, the modeling light will blink off until the
capacitors have recharged, and then turn on again.
Overheating Protection
After a long shooting session at a high power output, the recycling time of
the flash will increase automatically until the flash cools to a safe level. Once
cooled, it will begin operating as usual.
Overvoltage and Overcurrent Protection
The flash is protected against unstable voltages. Overcurrent protection is useful
when using a power generator (gasoline or electric) to power the flash unit.
Error Codes
In the event of a malfunction, the LED screen will display a blinking error code.
In addition, error codes E2 and E3 are accompanied by a beep warning.
E1: Temperature transducer problem. Turn the unit off immediately and contact
Impact customer service.
E2: This error code can appear after a long shooting session at high output or
rapid sequence. Turn off the flash unit and allow it to rest for 30 minutes.
E3: This error code will appear when the internal voltage of the flash is too high.
Turn off the power immediately. After 5 minutes, turn the flash back on. If the
error is still displayed on the LED screen, turn off the monolight and contact
Impact customer service.
