Background Operations
Time-Out-Timer (TOT)
Time-Out-Timer is used to prevent someone from using the same channel for a long time.
If the transmission exceeds the time preset by your dealer (default is 1 minute),
transmission will stop and an alert tone will sound. To stop the alert tone, release the PTT
key. Press the PTT key again to resume transmitting.
Your dealer can program a warning function to alert you before the TOT elapses.
Busy Channel Lockout (BCL) and Busy Tone Lockout (BTL)
When activated, the BCL and BTL feature will prevent you from talking on a channel that is
already in use. Press PTT while the channel is in use, the radio will generate an alert tone
and return to receive mode.
Carrier: If the selected channel is set by your dealer as “busy channel lockout” and is
being used by other users, press PTT, the radio will emit a Beep and will not
transmit signals.
CTCSS/DCS: If CTCSS/DCS is set on the selected channel that is programmed by your
dealer as “busy channel lockout” and is being used by other users, press
PTT, the radio will emit a Beep and will not transmit signals.
Opt signaling: If 2-Tone/5-Tone/DTMF/HDC-2400 is programmed on the selected channel
which is set by your dealer as “busy channel lockout” and is being used by
other users, press PTT, the radio will emit a Beep and will not transmit
signals.
Battery Save
It’s enabled by your dealer to minimize the amount of power used.
When there is no activity on the channel and no operation (no key is being pressed, and
no switch is being turned) is performed for 12 seconds, Battery Save is automatically
turned on. When a signal is received or an operation is performed, Battery Save is
automatically turned off.
