Time-Out Timer (Tot); Busy Channel Lockout - Kenwood TK-260G Instruction Manual

Time-Out Timer (TOT)

The purpose of the time-out timer is to automatically
interrupt continuous transmissions after a specified
time elapses. Holding down [PTT] for longer than the
programmed time causes the transceiver to stop
transmitting and generate a warning tone. Releasing
[PTT] cancels the warning tone.
Your dealer also can program a warning function that
alerts you just before the time-out timer stops your
transmission. After [PTT] is held down for the time
specified by your dealer, a warning tone sounds that is
different from the time-out timer tone.

Busy Channel Lockout

Activated or deactivated by your dealer, this function
prevents you from interfering with other stations who
may be using a channel. 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.
