Time-Out Timer (Tot); Busy Channel Lockout (Bcl) - Kenwood TK-190 Instruction Manual

Time-out Timer (TOT)

■
The TOT is used to automatically inhibit transmission
after a specified time elapses. If the PTT switch is
held down for longer than the programmed time,
the transceiver will stop transmitting and a tone will
sound. Release the PTT switch, then press it again
to continue transmitting.
• A warning tone will sound before the TOT expires if
programmed by your dealer.
Note:
◆ Depending on dealer programming, you may have to wait for
up to 60 seconds before you can resume transmitting after
transmission is inhibited.
◆ Depending on dealer programming, to prevent the TOT
from expiring, you may have to stop transmitting for up to 
seconds before resuming. If you resume too soon, the TOT
will not reset; the timer will continue counting down from where
it left off.

Busy Channel Lockout (BCL)

■
When activated by your dealer, you will not be able
to transmit while there is a signal, different from your
QT/DQT tone signal, present on the current channel.
You must either select a different channel or wait until
the signal is no longer present in order to transmit.
• If you press the PTT switch while a signal is present on
the current channel, a tone will sound and you will not be
able to transmit.
• To determine if there is a signal present on your channel,
press a key programmed with one of the following
functions: Monitor, Monitor Momentary, Squelch
OFF, or Squelch Momentary.
• If programmed by your dealer, you can override the BCL
by pressing the PTT switch two times within 0. seconds.
