3.9.1 KEYPAD LOCK

To lock/unlock the keypad, press and hold the [FCN] key. When locked,

“LOCKED” will be displayed if a key is pressed and a low beep will sound.

LOCKOUT EXCEPTIONS:

PTT unlocks the keypad during transmit for enabled DTMF key presses.

3.10 SCAN OPERATION

1. Slide Switch B (scan) up.

2. Slide Switch C (priority) down.

The display indicates scan operation

by flashing SCN.

Scan operates only while the radio is not transmitting. The radio checks for

signals on channels in the preset Scan List, as well as the channel selected

by the Channel Selector knob.

When a signal is detected, scanning stops and the message is received. The

received channel is shown in place of the transmit channel.

Once the signal ends, the radio continues to monitor the channel for the

preset scan delay time before it resumes scanning.

3.10.1 SCAN CODE GUARD CHANNELS

1. Slide Switch B (scan) up.

2. Turn the Squelch knob completely counterclockwise, past the detent, to

the Code Guard position.

When a signal is detected, scanning stops while the radio checks for the

proper Code Guard value. If the signal contains the proper Code Guard

value, the radio receives the message. Otherwise, the radio resumes

scanning immediately.

3.10.2 NUISANCE CHANNEL DELETE

If your radio is programmed for Nuisance Channel Delete and Channel Scan

is assigned to a top switch (Switch B, for example), a Nuisance Channel can

be temporarily removed from the Scan List by sliding Switch B down and

then back up.
