b) Start the announcement with the button
START/ STOP (73) . To stop the announce-
ment, press the button START/ STOP again .
c) With the button REPEAT/ STOP (72), an an-

1 . The announcement of storage M 6 may be locked
(see chapter 6 .4 .1, item 9) . If the switch MESSAGE
BANK is set to position 6 in this case, the an-
nouncement selected before is reproduced .
2 . If at least one zone button (4) is pressed at the
amplifier, after releasing the TALK button, the
announcement selected with the switch MESSAGE
BANK can be heard . To prevent this, leave a stor-
age location of the digital message insertion open
or cancel it and select this storage location with
the switch MESSAGE BANK .
4) The three LEDs POWER, SEND and BUSY (67)
give the following information:
POWER lights up when the amplifier is

Protective Circuit

The amplifier is provided with a protective circuit
against overload and overheating . If the protec-
tive circuit is activated, the LED PROT (22) lights
up and the amplifier is muted:
1 . for approx . 1 second after switching on
(switch-on delay)
2 . for approx . 1 second after switching off
3 . if the amplifier is overloaded
4 . if the amplifier is overheated; in addition, the
LED TEMP (20) lights up
If the LED PROT lights up during operation or if
it does not extinguish after switching on, switch
off the amplifier and eliminate the source of error .
