7. Mount Remote Flash on a Remote 622C
• Loosen the locking ring or lever on the flash to withdraw
the locating pin.
• Mount the flash on the 622C. Press the foot firmly
forward to ensure all contacts are secure.
• Tighten the flash’s locking ring or lever.
• Mount the 622C direct on a mini stand, or on a light
stand using a cold-shoe adapter.
8. Prepare the 622C Receiver
• Slide Receiver power switch to [ON]. The channel and group indicators light briefly. The
Status indicator turns steady red. The flash may fire once when turning the 622C on or off.
• Set Receiver to the same channel as the Transmitter, using [CH]. The channel indicator will
light for several seconds to indicate the current channel.
• While the channel indicator is lit, quickly press [CH] repeatedly to change the channel.
• Set the Receiver group to A or B or C using [GP] to select the desired Receiver (Lighting)
group.
9. Prepare Flash
• Set the Off/Master/Slave switch to Off (if present).
• Turn On the flash.
• Check that the flash indicates it is Ready.
• If using a C-TX with a class 2 flash, set the C-TX’s Fn 05 Eco = On and press [Set/OK].
• If using a C-TX with a class 3 flash, set on-flash Mode = E-TTL.
• Press Pilot/Test on the flash; the flash should fire. If it does not, or is slow to recover,
replace the flash’s batteries.
10. On-TX Flash (622C Transmitter only)
A flash can be installed on the 622C transmitter on top of the camera. It behaves much like a
Remote flash, but there are differences:
• Supports E-TTL, Manual levels and Multi (stroboscopic) modes.
• The On-TX flash output settings follow Group A settings.
• The On-TX flash has no channel. It is effectively direct-connected to the camera.
• The zoom setting is NOT controlled by the camera menu. It must be separately set on-flash
as Auto or 24mm to 105mm Manual zoom. This is independent of a global zoom setting.
• The on-TX flash may provide an AF-assist beam additional to the Transmitter’s AF-assist
beam, if that is enabled.
