Kenwood TM-441A - Manual (Page 19)

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.
