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 startup 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. Instal 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 startup 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 startup 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.

adjustment, or in sleep status.
