SWITCHES

CONTROLS &

INDICATORS

FUNCTIONAL DESCRIPTION

1

POWER
ON/OFF
SWITCH

A toggle switch applies the 27.5 volts nominal power supply to the
transceiver. The transceiver is switched to ON in the toggle UP Position the
transceiver is switched OFF in the toggle DOWN position.

2

POWER ON
LED
INDICATOR

A GREEN LED Indicates when the POWER ON/OFF switch is set to ON
and voltage is applied to the transceiver.

3

FUSE

A 5 Amp FUSE protects the 27.5 volts nominal power supply line. 

4

FUSE BLOWN
RED LED
INDICATOR

A RED LED indicates when the 5-Amp fuse is "blown", and External DC, AC,
Battery power is present.

5

SQUELCH
CONTROL

A linear potentiometer determines the squelch threshold level. When the
SQUELCH CONTROL is rotated in the counter-clockwise direction, the
SQUELCH GREEN LED indicates that the squelch is connecting
demodulated audio to the VOLUME control.

6

SQUELCH
INDICATOR 
GREEN LED

A GREEN LED indicates the squelch circuit is connecting demodulated audio
signal to the VOLUME control.

7

Tx  ON 
AMBER LED
INDICATOR

An AMBER LED indicates when the transceiver is keyed by the microphone
PRESS-TO-TALK (PTT) switch or remote land line, and the transceiver is
operated in the Tx mode. The Tx ON AMBER LED switches OFF, when the
transceiver is operated in the receive mode. 

8

VOLUME
CONTROL

A logarithmic potentiometer determines the audio level applied to the internal
speaker when the transceiver is operated in the receive mode. When the
SPEAKER/PHONE connector is in use the internal loudspeaker is
disconnected and the VOLUME CONTROL sets the audio level applied to the
external speaker or headphone.

9

MIC/PTT
CONNECTOR

A 5-pin connector functions as Microphone/PTT and Test Connector.

Pin 1 - PTT Signal Line
Pin 2 - Microphone Signal Ground
Pin 3 - Microphone Signal and Microphone DC Supply Line
Pin 4 - AGC test voltage
Pin 5 - Squelch test voltage

10

MICROPHONE
PTT

PRESS-TO-TALK (PTT) switch determines transceiver operating mode.
When the PTT switch is pressed, the transceiver operates in Tx mode. When
the PTT switch is released, the transceiver operates in Rx mode.

11

KEYPAD

Performs Channel/Frequency and Special Feature Selection (Refer Table 3-
3).
