Setting Manual Flash with the Slave Unit

Manual flash can be set manually with the slave unit. Do this in the
following cases:
(1) When you want to set the flash output with the slave units
individually for wireless or manual flash, as with studio flash units.
(2) When you use Speedlite Transmitter ST-E2 for wireless or manual
flash.
For example, if you have the slave ID set
to <1> for three slave units, all three
slave units will be controlled as if they
were one Speedlite in slave group A.
ID = A
