Overview

This section contains information about the control func-
tions, audio sources, audio states, programmable features
and operator instructions for the CDM Control Station.

General Description

The Control Station is an integrated base station package
designed for fixed locations. It serves as a local dispatch
point providing enhanced local control and supports com-
mon audio accessories such as a desk microphone or headset.

Performance

The Control Station was designed for the Professional Series
mobile radios. It is intended for fixed locations where protec-
tion from the elements (snow, rain, etc.) can be provided.
The station is relatively light and portable.
The fan is controlled by a thermal switch connected to the
power supply. This switching minimizes noise in office envi-
ronments while providing maximum cooling at elevated
ambient temperatures or during heavy transmit duty cycles.
The station is defined as intermittent transmit duty cycles,
but it may have surprisingly lower power slump when keyed
for long periods in an office shop environment.
