TIME-OUT TIMER (TOT)
The Time-out Timer is used to prevent you from using a channel for an extended
duration. If you continuously transmit for a preset time, the transceiver will stop
transmitting and a warning tone will sound. Release the PTT switch to stop the tone.
AUXILIARY PORT
Press the key programmed as [AUX] to activate the auxiliary port. The auxiliary
port is used with optional boards.
• "AU" appears on the display for 1 second.
DISPLAY BRIGHTNESS
You can cycle the display brightness between high, low, and off by pressing the
key programmed as [LED Brightness].
DIRECT ZONE CHANNEL
Press the key programmed as [Direct Zone-Channel] to immediately select the
lowest channel of the lowest zone.
BUSY CHANNEL LOCKOUT (BCL)
When activated, BCL prevents you from interfering on a channel that is already
in use. Pressing the PTT switch will cause a warning tone to sound and the
transceiver will not transmit. Release the PTT switch to stop the tone.
Note: Ask your dealer for an explanation on how BCL functions when using QT, DQT, RAN, or
Optional signaling.
If BCL Override has been programmed, you can transmit over the current signal:
1 Press and hold the PTT switch.
• If the channel is already in use, a warning tone will sound.
2 Quickly release and then press the PTT switch again.
3 Speak into the transceiver as you would during a normal call.

is pressed and/or released.

COMPANDER
If programmed by your dealer for a channel, the compander will remove excessive
noise from transmitted signals, to provide higher clarity of signals.
