Kenwood TK-2302E - Manual (Page 19)

BACKGROUND OPERATIONS
TIME-OUT TIMER (TOT)
The Time-out Timer prevents callers from using a channel
for an extended duration. If you continuously transmit for the
duration programmed by your dealer (default is minute),
transmission will stop and an alert tone will sound. To stop the
tone, release the PTT switch.
BATTERY SAVER
When activated by your dealer, the Battery Saver function
decreases the amount of power used after no signal is present
and no operations are being performed for 5 seconds. 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.
LOw BATTERY wARNING
While operating the transceiver, the Low Battery Warning
sounds an alert tone every 30 seconds and the LED indicator
blinks red when the battery needs recharged or replaced.
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 an alert 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 or DQT signaling.
QT/ DQT SIGNALING
The function uses QT/ DQT to segregate talk groups, so users
only hear calls from their own group.
