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
of the TOT timer, the TOT Re-key timer will be
activated. The transmission will be inhibited if
the
PTT
key is pressed before the expiration
of TOT Re-key timer (programmable by your
dealer as off, 1-60 seconds).
TOT Reset Time
The TOT Reset timer is activated upon release
of the
PTT
key. And the TOT timer will not be
reset until the TOT Reset timer expires. Press
the
PTT
key before the TOT Reset timer expires,
and the TOT timer continues to countdown.
The TOT Reset Time (Off, 1-15 seconds) is
programmable by your dealer.
EMERGENCY CALL
Hold down the Emergency Call key (the
exact time to hold down the key can be
programmable), and the radio will enter the
Emergency Call mode and switch to the preset
Emergency Zone/Channel. The radio will
transmit within a preset time period and then
receive within a preset time period circularly.
