Transceiver Controls and Annunciators
These are five white two-position toggle switches. When a switch is set to the ‘up’ position, audio from the associated
transceiver is routed to the phones.
Each switch has an associated Individual Receive Volume control, an interchangeable legend, and a TX select
indicator to show which transceiver is selected for Transmit (COM1 in the example above).
The Individual Receive Volume control is a rotary knob that adjusts the individual transceiver phones receive audio
volume from minimum (CCW) to maximum (CW).
The legends (above the switches) are interchangeable to allow customization.
