in the reception of the busy channel. Once the

signal has gone and there has been no activity

for 5 seconds, the radio will resume scanning.

•

To transmit on the Priority channel at any time,

simply press the PTT. The radio will switch

straight to the Priority channel. When you have

ﬁnished your conversation and there has been

no further activity for 5 seconds, the radio will

resume scanning the other channels. If you

don’t wish to listen to a busy channel, brieﬂy

rotate the Channel control (or press the

or keys) while the radio is paused on that

channel. The busy channel will be temporarily

removed from the scan group to allow time

for the channel to become clear again and

scanning will continue. The skipped channel

will be reinstated in the scan sequence after 30

seconds (see Auto Skip).

•

If you need to use your Priority channel (for an

urgent call), brieﬂy press the Channel control.

The scan will be cancelled and the radio will

jump straight to the Priority channel.

•

If the radio is paused on a busy channel and

you want to remain there, brieﬂy press the

key. The radio will exit scan and remain

on the busy channel. At this point you will no

longer be monitoring the Priority channel. To

resume Group scanning press the key

again.

NETWORK SCAN (NET-SCAN)

Net-Scan allows a group of radio users to maintain

communications even when the band is congested.

To achieve this all members of the Net-Scan group

must share a common CTCSS/DCS code and a

common set of scan channels.

Once activated, Net-Scan’s intelligent scanning

software keeps track of clear channels within

your scan group. When any member of the group

transmits, their radio automatically selects a clear

channel to transmit on. Other radios scanning

in the same Net-scan group will lock onto that

channel allowing all members of the group to join

the conversation.

If a signal from outside your Net-Scan group

appears on the chosen channel (either with

no code or the wrong code), the group will

automatically switch to a new clear channel at

the next transmission. In this way the group can

continue to communicate with minimal interference

to or from other users.

Enabling Net-Scan

Net-Scan is normally switched off by default but

can be enabled through your radio’s menu.

NOTE: When you enable Net-Scan you will also be

prompted to choose a suitable CTCSS or DCS tone

to be used by your Net-Scan group. All members of

your Net-Scan group must use this same code.

To Enable Net-Scan

1. Press and hold the Channel control to enter

the menu. The display will show the current

Squelch level setting.

2. Rotate the Channel control until ‘NS xxx’ is

displayed (where xxx is the current Net-Scan

setting) then press the Channel control to

select it.

3. Rotate the Channel control to change the

current Net-Scan setting.

•

To enable Net-Scan using CTCSS, select from

NS-01 to NS-50 (CTCSS tones 01 to 50).

•

To enable Net-Scan using DCS, select from

NS001 to NS104 (DCS codes 001 to 104).
