TIME-OUT TIMER (ТОТ)
It is sometimes necessary or desirable to restrict a single
transmission to a specific maximum time. This feature can
be useful when accessing repeaters to prevent repeater
time-outs, or when particularly trying to conserve battery
power. When TOT is activated, your transmit time is limited
to 10 minutes.
Access ‘TOT’ in Menu В to toggle the function ON or OFF
{page 17}.
When TOT times out, the transceiver generates beeps and
automatically returns to Receive. To resume transmitting,
release and then press
[PTT]
again.
BUSY CHANNEL LOCKOUT
This function prevents you from interfering with other
stations that may be using the channel that you select.
Pressing
[PTT]
while the selected channel is in use causes
your transceiver to generate an audible warning tone. Your
transceiver is inhibited in this situation so it will not transmit.
Release [PTT] to cancel the alarm and restore the receive
mode.
Access “BCL” in Menu B to toggle the function ON or OFF
(page 17}.
Note: When the correct Tone is received while CTCSS is in use,
transmission is not inhibited.
AUTOMATIC POWER OFF (APO)
Automatic Power Off is a background function that
monitors whether any buttons or keys have been pressed,
or whether the
Tuning
control has been turned. After
3 hours pass with no changes, APO turns OFF the power.
However, 1 minute before the power turns OFF, “APO"
starts blinking and a series of warning tones sound.
If the squelch opens or any settings are changed during the
3 hour period while APO is ON, the timer resets. When the
squelch closes or setting changes stop, the timer begins
counting again from 0.
Access “APO” in Menu B to toggle the function ON or OFF
(page 17}.
TRANSCEIVER LOCK
Transceiver Lock is suitable for a typical mobile installation
where you do most functions from your microphone. This
mode prevents accidental changes in settings at the
transceiver by others who may also be in your mobile.
