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.
2.2 FRONT PANEL
Refer to the diagram below:
2.3 POWER SWITCH
To switch the transceiver on, press and hold the left most knob until the radio powers up. The display will show
TECHNISONIC and the software version installed followed by the model number as determined by which RF modules
are installed. The display will then show the normal display for band 1. To switch off the transceiver at any time, press
and hold the left most knob for 2 seconds until the display shows OFF then release. If it is desired that the radio comes
on with the radio master in the aircraft, a power jumper may be installed (see installation instructions) such that the
radio is always on.
