TM721A.10
OPERATING PROCEDURES
Repeater cross-band operation allows the TM-721A to receive on one band
and retransmit the signal on the other band. An incoming signal will
automatically be switched to the sub-band. The TM-721A will then
retransmit the signal from the main band. Each band may contain offset
and sub-audible information (TSU-6 is required for decode). The encode
and decode tones for a single band must be the same. Of course, the
encoder or decoder may be shut off by using the [TONE] and [CTCSS] keys.
In addition, each band may contain a separate sub-audible tone.
1. Select the first frequency in the main band. If required select the
offset.
2. Select a tone if needed. Selecting a tone will not turn on the
encode or decode functions. To turn on the encoder, press the TONE
key (the [T] indicator will light in the main display).
3. Press the BAND key to move the contents of the main display to the
sub-display. The decoder can now be turned on by pressing the F key
and then the CTCSS key (the [CTCSS} indicator will light in the
sub-display).
4. Now select the second frequency in the main band. Follow steps 1 - 3
as needed to select the offset and tone information.
5. Adjust the main and sub-band squelch controls to the threshold point.
The TM-721A will transmit in the repeater cross-band mode if the
squelch controls are too low or a signal is received.
NOTE: The next two steps place the unit in the cross-band
repeater mode.
6. Press the F key
7. Press the A.B.C key within 5 seconds of pressing the F key. Three
dots should appear in the main and sub displays. The unit will now
operate as described.
