TIME OUT TIMER (TOT)

Time-out Timer (TOT)

This feature is able to prevent any single user
from using a channel for an extended period,
and to protect the radio against damage caused
by prolonged transmission. If the preset time
(off, 15~1200 seconds) expires, the radio will
automatically terminate transmission and keep
beeping. Beeps will not stop unless the PTT key
is released. The TOT default is 180 seconds,
which can fully satisfy common users. Any
change should be permitted by professional
technicians.
TOT Pre-alert
With a TOT Pre-alert timer, the radio can
generate a pre-alert tone at the programmed
time (1~10 seconds before the TOT timer
expires).
TOT Re-key Time
The radio features a TOT Re-key timer. If the
transmission is terminated due to expiration
