BACKGROUND OPERATIONS
TIME-OUT TIMER (TOT)
The purpose of the Time-out Timer is to prevent any caller
from using a channel for an extended period of time.
If you continuously transmit for a period of time that exceeds
the programmed time set by your dealer (default is 1 minute),
the transceiver will stop transmitting and an alert tone will
sound. To stop the tone, release the PTT switch.
Your dealer can program the TOT time in the range of
15 seconds to 20 minutes.
BUSY CHANNEL LOCKOUT (BCL)
When activated, BCL prevents you from interfering with other
parties who may be using the same channel that you
selected. Pressing the PTT switch while the channel is in use
will cause your transceiver to emit an alert tone and
transmission will be inhibited (you cannot transmit). Release
the PTT switch to stop the tone and return to receive mode.
Note: Ask your dealer for an explanation on how BCL functions
when using QT, DQT, DTMF, 5-tone, or FleetSync signaling.
BATTERY SAVER
If activated by your dealer, the Battery Saver function will
decrease the amount of power used when a signal is not
being received and no operations are being performed (no
keys are being pressed, and no switches are being turned).
While the channel is not busy and no operation is performed for
5 seconds, Battery Saver turns ON. When a signal is received
or an operation is performed, Battery Saver turns OFF.
Note: While the Battery Saver is operating, the LED may flash green
when receiving a QT/DQT signal which does not match the QT/DQT
tone/code set up in your transceiver.
