BACKGROUND OPERATIONS
TIME-OUT TIMER (TOT)
The Time-out Timer prevents you from using a channel for an extended duration. If you
continuously transmit for a preset time, the transceiver will stop transmitting and an alert
tone will sound. Release the PTT switch.
AUXILIARY PORT
Press the key programmed as [AUX A] or [AUX B] to activate the auxiliary port. The
auxiliary port is used with external devices.
• The
icon appears on the display when the auxiliary A port is active.
• The icon appears on the display when the auxiliary B port is active.
BUSY CHANNEL LOCKOUT (BCL)
If BCL is set up by your dealer, you will be unable to transmit if the channel is already in
use.
• “BUSY” appears on the display when you press the PTT switch. Use a different
channel or wait until the channel becomes free.
If your dealer has programmed BCL Override for your transceiver, you can override the
BCL by pressing the PTT switch again, immediately after releasing it, when the channel is
busy.
CONTROL CHANNEL HUNT
On digital Trunking channels, the transceiver automatically searches for a control channel.
• While searching for a control channel, the antenna icon will flash and no signals can be
received.
PTT ID
PTT ID is the transceiver unique ID code which is sent each time the PTT switch is pressed
and/or released. (PTT ID can be made only in analog operation.)
COMPANDER
If programmed by your dealer for a channel, the compander will remove excessive noise
from transmitted signals, providing higher clarity of signals. (The compander is used only in
analog operation.)
• Your dealer must set the compander for both the transmit side and the receive side in
order for the compander to operate.
TRANSMIT POWER
Your dealer has programmed a transmit power level for each channel. Power levels can be
high or low.
