Clearing Transmitter Settings; Test Flash From A Slave Unit - Canon ST-E3-RT Manual De Instrucciones

Clearing Transmitter Settings/Test Flash from a Slave Unit
When the flash mode of the firing group is set to <a> or </>,
exposure is controlled to obtain a standard exposure for the main subject as
a single group. If you shoot with multiple firing groups pointing toward the
main subject, overexposure may result.
The firing groups to be fired do not need to be consecutive; for example, A/
C/E can be set.

Clearing Transmitter Settings

You can return the settings for wireless shooting to their default
settings.
Even when the settings are cleared, the transmission channel, the wireless
radio ID and the C.Fn and P.Fn settings (p.54) are not canceled.

Test Flash from a Slave Unit

You can fire a test flash from a flash set as a slave unit. For the
operations, see the flash's instruction manual.
When two or more units are set to master, the master unit with the <D>
lamp lit in green is the one that fires.
