Communication System Setting up the communication system for use will require multiple connections to be made to the control box (1). All connections in this system are made by aligning the raised point of the “female” (2) fitting with the accompanying orange dot on the “male” (3) fitting. Once connected turn the “female” fitting to the Right to lock-in. 1 2 3 Communication System The headset for the Entry Officer is recognizable by the fact that in both of its ear portions it contains padding and speakers.
