OPERATING INSTRUCTIONS
2.1 GENERAL
A 2 line display and a keypad and 2 or 3 rotary knobs provide the operator control of the 2 or 3 RF modules
installed in the unit. The display is showing the activity of one RF module at a time, selected by pressing the
desired knob. The knobs have multiple functions including volume, channel, display dimmer. The microphone,
key line and headphone audio are separate for each of the two or three bands therefore switching from band to
band is performed at an audio panel such as the Technisonic A710 series. This allows for separate and
simultaneous operation on each of the bands just like having 2 or 3 separate radios. If combined operation is
desired, a Technisonic AMS-6000 audio mode selector may be used ahead of the audio controller.
