10.2 Remote slave flash mode
The flash unit supports Canon`s wireless E TTL
Remote System in slave flash mode.
At the same time, one or more slave flash units can
be remotely controlled from one master flash unit
on the camera (e.g. meca-blitz M400 C).
A slave flash unit can be assigned to one of three
possible slave groups (GROUP A, B or C). The master
flash unit can control all of these slave groups
simultaneously and at the same time take the set-
tings for each slave group into account.
So that multiple remote systems in the same room
do not interfere with one another, there are four
independent remote channels available (CH 1, 2, 3
or 4).
Master and slave flash units belonging to the same
remote system must be set to the same remote
channel.
The slave flash units must be able to receive the
light from the master flash unit with the integrated
sensors

for the remote mode .
Depending on the camera model, the camera’s
internal flash unit can also function as master flash
unit.
