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, the transceiver will stop transmitting and an
alert tone will sound. To stop the tone, release the PTT switch.
The default TOT duration is 1 minute. Your dealer can set the duration to last
from 15 seconds to 20 minutes.
Your dealer can also program a warning function to alert you before the TOT
expires. Continuously transmitting for the time specified by your dealer will
cause this warning tone to sound, allowing you to finish your transmission before
the TOT expires.

BUSY CHANNEL LOCKOUT (BCL)

The Busy Channel Lockout feature is activated or deactivated by your dealer.
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.

BEGINNING/ END OF TRANSMIT SIGNAL

Your dealer can enable or disable the Beginning/ End of Transmit identification
signals. These signals are used to access and release some repeaters and
telephone systems.
A Beginning of Transmit (BoT) Signal is sent when you press the PTT switch.
An End of Transmit Signal (EoT) is sent when you release the PTT switch.
