This completes the installation of the mobile radio in the
Desk Top Station Assembly.
INSTALLING THE DESK TOP STATION
AC Power
The Desk Top Station power supply must be connected
to AC power with the fused and ON/OFF-switched AC
power cable found at the back of the Desk Top Assembly.
The transformer straps are shipped set for a 120 volt power
source:
120volts ±10%, Single-Phase, 50/60 Hz, 4 amps,
500 watts
Refer to Power Supply Maintenance Manual LBI-38751
for procedures to change the transformer straps to accommo-
date a 240 volt power source:
240volts ±10%, Single-Phase, 50/60 Hz, 2 amps,
500 watts
Microphone
A desk microphone, a DTMF microphone, or a standard
mobile microphone can be used. The microphone connects
to the Desk Top Station at J101 on the Front Cap under the
Control Panel.
Antenna
