Revert Channel

If you press the

PTT

key, the scan will be

turned off and the radio will switch to the

Revert Channel to transmit. This feature is
programmable by your dealer.

Off-Hook Scan

If this feature is enabled by your dealer, the radio

will be allowed to scan no matter whether the

palm microphone is in an off- hook position or
not. Otherwise, the scan will be disabled with
an off-hook palm microphone.

BUSY CHANNEL LOCKOUT (BCL)

This  feature  helps  prevent  transmission  on  a
channel  that  is  already  in  use,  and  it  can  be
enabled/disabled  by  your  dealer.  If  you  press

the

PTT

key on a busy channel, transmission

will be inhibited and an alert tone will sound.
If the

PTT

key is released, the alert tone will

cease, and the radio will return to Rx mode.
When the channel is free, press the

PTT

key

again to transmit.

BCL OVERRIDE

If this feature is enabled, you can override the
BCL feature to transmit on a busy channel.
If you press the

PTT

key, a BCL alarm will

be heard; press the

PTT

key again within

0.5 seconds to override the BCL feature and
transmit on the busy channel.

DTMF CALL
Manual Dial

Hold down the

PTT

key, and then press any

key  on  the  DTMF  keypad  of  the  microphone
to  transmit  the  corresponding  DTMF  signal.
Meanwhile, you may hear relevant tones.
Release  the

PTT

key. The radio will remain

in transmission mode for 2 seconds
(programmable by your dealer), and then
press another numeric key within 2 seconds to
continue the transmission.
