Programming Channels into Net-Scan

All radios in your Net-Scan group must have the

same channels programmed into their Net-Scan

memory.

Your radio’s Net-Scan memory has already been

factory programmed with 43 of the available

80 channels. The remaining 37 channels, which

consist of the 32 repeater input/output channels,

2 telemetry channels and 3 guard band channels,

have not been included to minimise the risk of

interference to other services on these channels.

IMPORTANT: When adding channels to Net-Scan,

please consider the following:

The transmitter on your radio is inhibited on

channels 22, 23 and channels 61, 62, 63 as

required by the ACMA. This makes these channels

unsuitable for use as Net-Scan channels.

You should not include any repeater channel

unless you have conﬁrmed that the channel is

not allocated to a repeater in your area. Using an

active repeater channel in Net-Scan may result

in interference to other repeater users on that

channel.

Starting Net-Scan

With Net-Scan mode enabled, press the

key.

A high beep will be heard and the icon will

animate. During this time the channel numbers will

change rapidly as the channels are scanned.

Using Net-Scan

When a member of the group initiates a

transmission their radio will automatically select

a clear channel to transmit on. Other radios

scanning in the same Net-Scan group will locate

the transmission by identifying the group’s CTCSS/

DCS code and open their Squelch allowing the

transmission to be heard across the entire group.
