External settings and
connections
Connect antennas
The FM input must be connected to an antenna or cable
network with a COAX cable of 75 Ohm. A connector
for the FM input is provided with the unit. The AM
input can be connected to the loop-antenna delivered
with the unit.
3.4.5
Tuner region selection
To set the tuner region to either ASIA/USA or Europe:
1 Press and hold in:
•
the tuner frequency up/down keys (12).
•
the tuner memory key (15).
2 Press the power button (31) to switch the system on.
3 Either USA or EUP will be displayed.
4 To toggle between USA or EUP, switch the system
off, and repeat from step 1.
3.4.6
Priority/VOX activated
microphone
Note: Microphone 1 has different operating modes:
Priority mode
Connect the microphone to the DIN-socket at the rear
of the unit and enable the priority mode with
configuration switch 1 (set to ON-position). This
requires a microphone with a priority switch on contacts
4 and 5 of the 5-pin DIN-connector, such as the table-
top microphone LBB 1950. In this mode, microphone 1
will have priority over microphones 2 and 3 and the
background music. Activating this microphone will
mute the other microphones and the music and will also
override zone switching and zone attenuation. Priority
announcements will even be heard in deselected zones.
This mode is normally used for important (emergency)
announcements. You can select a chime signal to
precede such a priority call with configuration switch 3,
a speech filter with configuration switch 4 and phantom
power with configuration switch 5.
