Controls, Indicators and Front Panel Connector

This topic describes the Park Air T6MC controller's controls, indicators and front panel connector.

Front Panel

The controller's front panel is illustrated below.

Volume Control

A rotary control used to adjust the volume of the internal loudspeaker.

Intercom Switch

The intercom switch, when pressed down, allows an operator to talk to other controller positions without
keying the transmitter.
The intercom facility must not be used when the controller's external PTT signal is used as the
keying signal.
Using the intercom facility with external PTT will cause the transmitter to key and broadcast the
intercom speech.

Busy Indicator

A red indicator illuminates when a signal is received, or when transmitting.

Supply Indicator

A red indicator illuminates when an ac input supply, or a dc input supply, is connected and the rear panel
supply switch is set to on.
