GETTING STARTED

1. Prepare the Camera

• Set the camera to a Creative exposure mode (P, Av, Tv or M), not a Basic mode (Scenic,

Sports or Flash-disabled.)

• Set External Flash menu to Flash Firing = Enabled, and Wireless = Disabled.

• Disable Silent Shooting mode.

• Enable AF-Assist Beam (e.g. C.Fn III/5 = 0, Enabled).

• Set AF mode to One-Shot.

• Disable Face Detection mode.

2. Prepare the Units

• Remove the protective film from each 622C’s top plate, and/or from the AF-assist beam’s

red cover.

• Wipe the contacts in both the hot-shoe and the hot-foot to remove oils and other dirt.

• Insert fresh, fully-charged batteries. They are critical. Do not make assumptions.

Recommendation: load all units with good quality (i.e. more expensive) new Alkalines (1.5v)

to start with. When all is working well, good quality NiMH (1.2v) can be used. Do NOT use

Lithium (1.6v).

3. Reset / Clear to restore Factory Defaults

• The units as delivered may not be in a factory-fresh state, or may be altered accidentally by

a user. When first starting to use the units (or if they seem erratic), perform a Factory

Defaults reset.

622C Transmitter Reset (Clear) C-TX Controller Reset (Clear)

• Hold down [CH SET] plus [GP SET] at

the same time.

• Keep holding until the Status indicator

has winked red-green alternately 3 times

and then stays red.

• Release the buttons.

• Factory defaults will be restored to:

622C mode = Remote

Flash mode = E-TTL

Sync mode = HSS.

• The C.Fn (AF-Assist Beam) setting is

not changed.

• Hold down [MODE] plus [SYNC] at the

same time. The display will show only a

steady “CLR”.

• Keep holding until “CLR” winks slowly.

• Release the buttons.

• The Main screen will appear, showing all

the groups in TTL.

• Note: Updating the firmware performs

this step automatically

• If the CLR screen does not appear,

navigate back to the Main screen, and

try again.
