TROUBLE SHOOTING
Full-power flash
This can happen if the shutter release is fully pressed before the system has aligned every component. The Fire!
command can over-ride any setting up in progress.
On start up or on any major adjustment to remote flashes, press half-shutter and release to force system
updating.
Erratic Behaviour
Unmount all equipment, then re-mount ensuring the hot-foot is pressed fully in.
Replace the batteries in the 622s, preferably with Alkaline ones. Make no assumptions.
Reset the 622s to factory default settings. (Hold [CH SET] and [GP Set] until the Status indicator flashes red/green
three times, then release.
Reset your Speedlite. Install the Speedlite directly on a type A camera, and reset the flash using the menus
“Flash Control / Ext Flash Function settings / Clear Speedlites Settings” and "Flash Control / Clear External Flash
C.Fn settings" , which re-set most main and C.Fn settings.
Reset the factory settings of the camera.
Fails to power on or automatically shuts down
The batteries are installed incorrectly or are exhausted. The device will power down automatically before the
battery is fully depleted to avoid being over-discharged.
Install fully charged batteries according to the battery compartment indicators.
Battery low – on start up or half-shutter; Status will rapidly wink Red/Green, and the CH and GP indicators will
dimly wink also. If the voltage becomes low (total 2.2 volts), the 622 will turn off automatically. Batteries can be
too low on start up to trigger this action.
The flash does not fire
Ensure the batteries of all devices are fully charged, and flash is recycling in time.
Check the connection between the 622 and camera, and 622 and flash.
Ensure that the indicators show matching channels and lighting groups.
Check that flash is not disabled by its overheating protection, is not in continuous zoom adjustment, or in sleep
status.
Use the Pilot button to test the flash.
