multi purpose room
Caution: Turn the delay switches carefully
to a new position until you feel that it
clicks into position, to prevent that a
switch is positioned between two
numbers, which would result in a wrong
delay setting.
Note: When a master-slave configuration
is used for rooms which are always sepa-
rated, the delay switch positions can be
determined per system and the delay
caused by transmission from master to
slave transmitter can be ignored.
