Time-out timer
To prevent accidental prolonged transmission, etc., the trans-
ceiver has a time-out timer. This timer cuts a transmission
OFF after 1, 3, 5 or 10 min. of continuous transmission. This
timer can be cancelled (default).
Approx. 10 sec. before the time-out timer is activated, the
transceiver emits a beep tone as a warning.
This can be selected with “TOT” in set mode.

■
PTT lock
To prevent accidental transmission, etc., the transceiver has a
PTT lock function.
This can be selected with “PTT LOCK” in set mode.
