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.
