Now select the desired upper tuning limit using the

MHz key and tuning control, or microphone UP/DWN

switches.

With our example TM-241 we want the upper band

limit to be in the 145 MHz band, and therefore dial

up 145.100 MHz.

Press the F key for longer than 1 second. The F

indicator will again begin flashing.

Press the SHIFT/AL key within 10 seconds. A long

beep will sound and the F indicator will turn off in

the display. This indicates that the upper limit has

been stored in memory.

8. To confirm that the programming was properly

performed rotate the tuning control or press the

UP/DWN switches. The transceiver should not go

above or below the programmed band limits.

9. To clear both programmed limits simultaneously you

should initialize the VFO memory using the

procedures discussed on page 21. You can reprogram

either limit independently by following the

appropriate instructions above.

5-2-5 ALT (TM-541A/541E only)

The ALT system operates similar to an AFC (Automatic

Frequency Control) system. This system is useful when

the frequency of either station starts to drift. When this

occurs distortion of the signal is the usual result. The

ALT system will detect the drift and shift the frequency

to compensate.

To activate the ALT function

1. Press the F key momentarily. The F indicator will turn

on in the display.

2. While the F indicator is on press the DR/DT/ALT key.

The ALT indicator will turn on and the receiver will

automatically center itself on the incoming signal.

3. To release the ALT function press the F key

momentarily and then the DR/DT/ALT key.
