Transmit Time-Out Timer (TOT)
This limits Tx time after the PIT is held (1-60 mins),
after which the transmitter automatically uri-keys
(even
If
the
PIT
IS
still held). To reset the timer and
transmit again. the PIT must first be released. This
feature is useful to limit long key-down periods when
the cross-band repeater feature is enabled, or in the
event of
a
stuck microphone (wedged between the
car seats, for example). The TOT is enabled via
menu function 29 on page 70: select a timer duration
of 1-60 mins or OFF. When active,
TOT
appears
between the channel displays.
