SUGGESTIONS

Batteries

The 622C is designed primarily as a 3v (2x 1.5v) unit, but can be used with lower-output batteries

e.g. 2.4v (2x 1.2v). However, they require more constant attention by the user to battery condition.

• Alkaline batteries start at 1.5 volts and slowly drop voltage during use.

• Well-maintained NiMH rechargeables in good condition start at around 1.2 volts, (under

load) and hold their voltage until almost exhausted.

• Alkalines lose little voltage when not in use, but NiMH rapidly lose substantial voltage.

• The 622Cs are programmed to cut out at about 2.2 volts for the pair. A good pair of

Alkalines give a starting overhead of 0.8 volts, while even the best NiMH pair have an

overhead of only 0.2 volts above cut-out.

• Alkaline characteristics are well suited for use in the 622C, and testing the triggers with a

quality new set can help rule out batteries as a source of a problem.

• NiMH Rechargeables are great as flash batteries, being capable of a rapid discharge into

the flash’s capacitor.

Battery Orientation

Flashes are often used in low light. It can be hard to read the embossed polarity markers at the

bottom of the battery case. Use a silver marker pen to highlight the two [+] markers.

Camera’s Custom/My Menu

Set up the Flash Control/Function menu as the first My Menu item. Then set the My Menu to

appear first when Menu is called.

Hybrid Mode - Master and Slave with 622Cs

Use two 622Cs to bridge the distance from camera, and Canon Wireless to fire 2 or more flashes.

• Only Manual mode can be used. Set camera to Manual flash mode, 1CS or HSS.

• Place a 622C on-camera.

• Use a non-controllable Master flash (e.g. 580EX) directly on the other 622C,

or a controllable Master flash (e.g. 580EXII) connected by i) an adapter which has only two

wires between hot-foot and hot-shoe, or ii) a PC-sync cord to an adapter foot.

• Set the Master flash on-flash as Master, Manual mode and power level, 1CS or HSS.

Groups are probably not available (untested).

• Set the other flash (e.g. 430EX) to Slave and E-TTL. Ensure the slave’s wireless sensor

can see the master’s flash head.

Test fire. The 622Cs should communicate, and the remote 622C will fire the Master. In turn, the

slave should change to a manual power level and fire. Try with a different Manual level on the

Master.

Light Meter Technique using 622Cs

• Set Manual levels, either by External Flash menus or by on-flash settings.

• The test fire will be at the level as it is displayed on the LCD of the flash.

• The test button will not change the setting of the flash.

• If Remote control is being used, first press half-shutter to ensure that settings are applied

• E-TTL will produce a pre-flash, which may confuse the light meter.

• Trigger with any 622C on the same channel. It may be a hand-held one.

• With the C-TX controller, connect a suitable Light Meter to the PC-sync IN port.

Mixing with Other Triggers

Other non-ETTL triggers such as the RF602, RF603 or Cybersync triggers can be mounted on the

622C transmitter or a remote 622C to fire the other trigger’s remote receivers.
