IMER
(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.
Your dealer can program a warning function to alert you before the TOT expires.
Continuously transmitting for the time specified by your dealer will cause the
warning tone to sound.

OCKOUT
(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.

ROUND
You may occasionally experience an interruption in service (due to a power
failure, etc.). During such an occurence, you can continue communication by
using the Talk Around feature, if it has been programmed by your dealer.
Talk Around allows you to communicate directly with other transceivers, without
the use of a repeater. However, if the station you want to contact is too far away,
or there are geographical obstacles in the way, you may not be able to contact
the station.
Toggle Talk Around ON and OFF by pressing the key programmed as
Talk Around
.
• The indicator corresponding to the
Talk Around
key lights while the Talk Around function is ON.
• When using Talk Around, the “receive” frequency is used for both transmission and
reception, and the QT/DQT “decode” signalling is used for both encoding and decoding.
M
ONITOR
Press the key programmed as
Monitor
to turn the transceiver signalling OFF.
While signalling is OFF, you can hear all signals received on your current
channel. With signalling ON, you can hear only signals that match the signalling
programmed in your transceiver. Press the
Monitor
key again to return to
normal operation.
Press and hold the key programmed as
Monitor
for 2 seconds to listen to weak
signals that you cannot hear during normal operation, and to adjust the volume
when no signals are present on your selected channel. Press the
Monitor
key
again to return to normal operation.
