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.

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