Figure 1.28, table 1.1, table 1.3 and table 1.4 illustrate
the calculation of the extra master-slave signal delay.

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.
