3.2.1 Remote Station Microphone
The microphone for remote control stations is connected to the remote station microphone connector as
shown in Figure 3-2. See Section 3.1.2.2 when connecting a microphone to a local control station.
The Control Station’s microphone
MUST
be connected to the Control Station’s
remote station microphone connector found on the front-left faceplate panel.
Connecting the Control Station’s microphone to the transceiver will result in improper
operation of the remote control features.
3.2.2 Intercom
Switch
The Intercom switch places the Control Station in one of two intercom modes, or normal mode. The
Intercom switch may be set to one of the following three (3) settings:
M (UP - Momentary position): This is a spring loaded momentary position that places the local station in
the INTERCOM mode until the operator releases the switch, at which time it will return to the OFF
position. Holding the INTERCOM switch in the M position, and keying the Local Station Microphone,
will NOT key the transceiver. Local Station Microphone audio will be heard only at remote controllers
until the switch is released.
OFF (Center position): This position is the NORMAL mode. Transmissions made from the Local Station
Microphone will key the transceiver and transmit audio will be heard only over-the-air. Remote
controllers will also hear the Control Station’s Local Microphone audio if the REMOTE switch is set to
the ON position.
ON (Down position): This position places the Control Station operation in the INTERCOM mode.
Transmissions made from the Local Station Microphone will NOT key the transceiver, Local Station
Microphone audio will be heard only by Remote Controllers, and transmissions made by Remote
Controllers will only be heard over the Local Speaker (Remote Controller transmissions will not key the
transceiver).
3.2.3 Remote Switch and LED Indicator
The Remote switch provides the local control operator the ability to enable access by remote controllers.
The Remote switch may be set to one of the following two (2) settings:
ON (Down position): This position is the NORMAL mode of operation. It enables Remote Controller
access to the Control Station and illuminates the Remote Indicator LED. Remote Controllers will be able
to transmit or receive over-the-air via the Control Station’s transceiver.
OFF (UP position): This position disables radio access to and from Remote Controllers. In this position,
Remote Controllers will not be able to transmit or receive over the Control Station’s radio.
The Remote Switch must be set to the ON position to allow remote controllers to transmit
and receive over-the-air via the Control Station’s transceiver.
3.2.4 Station Volume Control
The Station Volume Control functions as the Control Station’s master volume control on stations
equipped with the remote control option. The volume control setting for the transceiver is pre-
programmed to a fixed level to ensure proper Control Station operation in remote applications.
