Test Communication and Flash Readiness [Test]

• Press and hold [Test] to awaken the flashes. The Status Indicator will light green.

• The 622Cs and their flashes will awaken, and their indicators show ready. Ensure flash pilot

lights are showing fully charged.

• Release [Test] to fire a test firing. The Status Indicator will turn red.

Set Super Sync timing [Fn] 01 Super Sync Timing

• Default value is 0.0.

• The setting is global and applies to all groups in SS.

• Long press [Fn] then [Up] or [Down] to select Fn 01 -

SS.

• Press [Left] or [Right] to step between 0.0 and 2.0 in

0.1 timing increments.

• Press [Set] to return to Groups.

Using Super Sync (Flash Burn)

Super Sync is designed to allow studio flashes to be used at fast shutter speeds up to 1/8000s.

• Connect the studio flash to a remote 622C using a PC-sync cord.

• Set C-TX shutter sync to Hi-speed sync (HSS).

• Flash output of 1/1 may be needed for this technique.

• Take a test shot and check image for a shutter shadow. Adjust the timing between 0.0 and

2.0 until the optimum lighting is achieved.

• There may be a gradient in the image which will need correcting in post-processing.

Enable AF-Assist Beam [Fn] 03 AF Beam

The red AF Beam on the C-TX can be either On or Off.

• Default value is On.

• Long-press [Fn] to show function screen.

• Press [Up] or [Down] repeatedly to show Fn 03 - AF.

• Press [Right] or [Left] to toggle between On and Off.

• Press [Set/OK] to apply and return to Groups.

When the Beam is enabled, it will still fire only when the

camera calls for it.

Enable use on non-Canon cameras [Fn] 04 Legacy Flash Trigger

Only Canon cameras talk the Canon code that the C-TX

works with. Some other brands, like Fuji, falsely make the

C-TX think it is on a Canon camera. Function 04 prevents the

false detection, and the C-TX then works as a simple trigger.

• Default value is Off. Turn On only when required.

• Only Manual operation is available, not E-TTL.

• Long press [Fn], then [Up] or [Down] for Fn 04 - Leg.

• Use [Left] or [Right] to toggle between Off and On.

• Press [Set/OK] to set and return to Groups.

• On 2007+ flashes, Manual outputs are remotely

controllable in Groups. Other flashes need their outputs to be set on-flash,

• Warning: Leaving Fn 04 set to On disables all control when the C-TX is on a Canon.
