Brief Description of System Units - VHF/AM Mobile Transceiver System 910200 consists
of the following items:
(a) Transceiver Model 91-DE, Part Number 901006-2, Series 1, is a VHF/AM transceiver
which operates in simplex and allows quick keypad access and LCD display of the
frequency range 117.975 MHz to 138.000 MHz with 25 kHz channel spacing. The
transceiver operates from a 12 volts dc nominal vehicle power supply (negative
ground only). An optional extra cost dc to dc converter P/N 863118-1 can be installed
in the transceiver to allow operation from an input supply from 10.8 to 30.0 VDC. A
general view of the transceiver is given in Figure 1.1. The transceiver is normally
located under the dashboard of a vehicle using a mounting bracket and mounting
hardware.
(b) Mounting Bracket, Part Number 913053-1, is a U-shaped aluminium alloy bracket
which, together with items of hardware included in the Mounting Hardware Kit P/N
869024-1, is used to mount the transceiver under the dashboard of a vehicle.
A view of the transceiver with mounting bracket is given in Figure 1.2.
(c) Power Input Cable Assembly, Part Number 863701, is a three-metre length of two-
core cable terminated at one end by a two-pin, female contacts, connector, which
mates with the two-pin, male contacts, connector located at the left-rear of the
transceiver. The unterminated end of the cable is connected to the 12 VDC vehicle
power supply negative-ground during installation.
A view of the cable assembly is given in Figure 1.3.
(d) Microphone Assembly, Part Number 961070-1, consists of a Microphone and a
mounting bracket, P/N RK6MB.
A general view of the microphone assembly is given in Figure 1.4.
The microphone is a rugged hand-held microphone housed in a high impact plastic case
which includes a rear case hang-up button for storage on the mounting bracket. The
dynamic microphone is a noise cancelling type with a pre-amplifier, press-to-talk switch,
and a retractable three-cord cable terminated by a three-pin male contacts, connector
which mates with the MIC/PTT connector located on the front panel of the transceiver.
The microphone dc supply for the microphone is supplied by the transceiver. The
mounting bracket, provided with the microphone, should be mounted in a convenient
location near the transceiver. A small screwdriver which can be used for releasing the
modular plug located in the microphone head is supplied with the microphone.
