4. After the least significant digit has been entered
press the ENT key again to signify you want the
radio to change frequency. If you entered the fre-
quency down to the nearest 100 Hz a beep will
sound and the radio will automatically change to

4-2-12. ALT (Auto Lock Tuning) System (Optional in
the TS-790A/790E)
The ALT system operates similar to an AFC (Automat-
ic 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 correct for this apparent
drift.

The frequency display will not change, even though
the receive frequency might shift in order to properly
tune the incoming signal.

The ALT function will turn off if you turn on ALT dur-
ing Memory Channel operation and transfer to another
memory channel or VFO operation.
