2 C: Adjust settings for the master
flash.
Choose the flash control mode and
flash level for the master flash and the
flash units in each group:
• TTL: i-TTL flash control
• qA: Auto aperture (available only with compatible flash
units)
• M: Choose the flash level manually
• – – (off): The units do not fire and the flash level cannot be
adjusted
Set the master flash to channel 3.
3 f: Set the remote flash units to channel 3.
4 f: Group the remote flash units.
Choose a group (A or B) for each remote flash unit. Although
there is no limit on the number of remote flash units that may
be used, the practical maximum is three per group. With
more than this number, the light emitted by the remote flash
units will interfere with performance.
