4-2-5. ALT (TM-531A/531E only)
The ALT system operates similar to an AFC (Automatic Fre
quency Control) system. This system is useful when the fre
quency
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 momentar
ily. The F indicator will turn
on in the display.
