OPERATING INSTRUCTIONS
2.1 GENERAL
The TDFM-600/6000 transceiver is designed to operate in the same fashion as the Motorola XTS-3000
portable radio. The display has been rearranged into a 2 line display from 4 and some of the numeric
keys also double as function keys. Two or three XTS-3000 RF modules are installed in the unit. The
display is showing the activity of one 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. This allows for separate and simultaneous operation on each of the
bands just like having 2 or 3 separate radios.

To switch the transceiver on, press the left most knob. The transceiver will immediately power up. The

band 1. To switch off the transceiver at any time, press and hold the left most knob for 2 seconds until
the display shows AOFF@ then release.
2.4 KNOBS
The transceiver will have two or three knobs depending on how many RF modules are installed. The
