Microphone P/N 861902-1
Microphone Assembly Part Number 861902-1, Series 1, is a rugged hand-held microphone
housed in a high impact plastic case. The dynamic microphone is a noise cancelling type with a
two-stage pre-amplifier, press-to-talk switch, and a retractable three-core 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 dc supply for the microphone is supplied by the transceiver. The
microphone bracket can be mounted on the left or right side of the SPG-010 Power
Supply/Battery Charger as required.
1.2.4 Antenna
This unit is designed for use with a 50 ohm impedance antenna (not supplied). A 50 ohm RF UHF
type connector is provided on the rear of the transceiver unit for interfacing with an antenna.
1.3 MODES
OF
OPERATION
Refer to Section 4 for additional operating modes.
1.3.1 Transmit/Receive
The transceiver may be operated in either of two modes; transmit or receive, as selected by the
Press-to-Talk (PTT) switch on the microphone.
(1)
TRANSMIT MODE
- When the PTT switch on the microphone is pressed, the transceiver
operates in the transmit mode. The PTT signal line is grounded by the microphone PTT
switch via the microphone lead and the MIC/PTT connector to the transceiver. The Tx
ON amber LED will go ON, indicating that the transmitter is activated.
Transmission will occur on the channel frequency indicated on the front panel. Refer to
Section 4 for transceiver details
(2)
RECEIVE MODE
- When the PTT switch on the microphone is released, the transceiver
operates in the receive mode. The Tx ON amber LED will go OFF, indicating that the
transmitter is inhibited. Reception of the frequency displayed on the transceiver will
occur.
The setting of the SQUELCH CONTROL determines the squelch threshold level. When
the SQUELCH CONTROL is rotated in the counter-clockwise direction, the SQUELCH
INDICATOR green LED will go ON, indicating that the squelch circuit is connecting the
demodulated audio to the VOLUME CONTROL. The setting of the VOLUME CONTROL
determines the audio level produced from the internal speaker. When the VOLUME
CONTROL is adjusted in the clockwise direction, the audio level will increase.
NOTE
When the connector of the external loudspeaker or
head phone is connected to the SPEAKER/PHONE jack,
the internal loudspeaker is disconnected and the
VOLUME CONTROL will control the audio level of the
external loudspeaker or headphone.
