4.4 INTERCOM
OPERATION
Control Stations equipped with Intercom and Remote switches may make intercom calls to and from
remote controllers connected to the Control Station. The Intercom and Remote switches determine when
and how the Control Station makes intercom calls.
4.4.1 Continuous Intercom Operation (Intercom-Only Mode)
The Continuous Intercom mode of operation allows transmissions between the Control Station and
Remote Controllers (over-the-air transmissions via the Control Station are disabled during this mode).
Perform the following steps to make an Intercom call:
1.
Make sure the Control Station is powered up (see Section 4.1).
2.
Set the INTERCOM switch to the ON position.
3.
Set the REMOTE switch to the OFF position.
4.
Press and hold the PTT switch on the Local Station Microphone at the beginning of each
transmission. Release the PTT switch at the end of each transmission.
In the Continuous Intercom mode, neither audio from the Local Station Microphone or a
remote controller will be transmitted over-the-air. Only intercom communications is
possible!
4.4.2 Momentary Intercom Operation
The M position on the Intercom switch is spring-loaded (momentary) and returns the switch to the OFF
position when released. This switch position allows the Control Station’s local operator to make an
intercom call without leaving the Control Station in continuous intercom mode. This is a convenient
position to use since the ON position disables over-the-air transmissions from the Control Station.
Perform the following steps to make a Momentary Intercom call:
1.
Make sure the Control Station is powered up (see Section 4.1).
2.
Set the INTERCOM switch to the M position.
3.
Set the REMOTE switch to the OFF position.
4.
Press and hold the PTT switch on the Local Station Microphone at the beginning of each
transmission. Release the PTT switch at the end of each transmission.
5.
Release the INTERCOM switch when the intercom call is complete.
Audio from the Local Station Microphone or a remote controller will NOT be transmitted
over-the-air during this switch configuration. Only intercom communications are possible!
