3.1 Introduction
Information in this section consists of the functional and operational procedures for the CC450-0V2
Communications Controller. All derivative units operate in a similar manner, but may have minor
differences such as no transceiver annunciators.
3.2 General Information
The CC450-0V2 Communications Controller is a compact, easy to install communications controller. It is
designed to provide RELAY and/or SIMULCAST operation for up to 4 transceivers. With these functions, the
aircraft can become an airborne repeater or a multi-frequency transmitting platform.
When used to its potential, the CC450-0V2 provides increased efficiency and reduced workload for
communication operations.

Before powering up the CC450-0V2 put all transceiver switches in the down (inactive) position.
To turn the unit on, move the Power Switch to the up (ON) position. The Power Annunciator should light
GREEN and the RT1 and RT2 Transceiver Annunciators should flash alternately for 0.5 seconds.
When the Power Switch is turned OFF, the CC450-0V2 will allow normal transmit and receive operation
of all transceivers that are connected to the CC450-0V2.
