Selecting Net-Scan

When Net-Scan is enabled, a new Network Scan option becomes available on the

key. To select

the Network Scan option, press the

key followed by the

key to cycle through the available

scan groups until ‘NETWK’ is displayed. The radio is now in the Network Scan mode.

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 reserved channels, have not been included to minimise the risk of interference
to other services on these channels.

To quickly determine which channels are currently programmed into the Net-Scan group.

1. With the NETWORK scan group selected, briefly press the

key. ‘F’ will be displayed.

2. Press the

keys to step through the channels. Only channels that are stored in the Net-

Scan memory will be displayed. Take a note of the channel number to compare with the other radios
in your Net-Scan group.

When finished, press the

key to exit.

To add or remove Net-Scan channels

1. With Net-Scan mode enabled, select the require channel using the

keys.

• If the channel is currently in the Net-Scan group the

icon will be visible above the channel

display. To remove the channel, hold the

key until a low beep is heard.

will disappear

indicating the channel is no longer in memory.

• If the

icon is not visible above the channel display, the selected channel is not in the Net-

Scan memory. To add it, hold the

key until a high beep is heard.

will appear to confirm

the channel is now in memory.

Repeat step 1 to add or remove further Net-Scan 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. These channels are therefore unsuitable for use as Net-Scan channels.

You should only include a repeater channel AFTER you have confirmed that the channel is not allocated
to a repeater in your area. If you inadvertently include an active repeater channel in your Net-Scan, you
or others in your Net-Scan group may cause interference to other repeater users on that channel.

Starting Net-Scan

With Net-Scan mode enabled, press

The radio will begin scanning and ‘NSxxx’ (where xxx is the

selected CTCSS or DCS tone) will be displayed.

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
containing the groups CTCSS/DCS code and open their Squelch allowing the transmission to be heard
across the entire group. When the transmission ends, the other radios in the group will immediately
resume scanning.

Any member of the group who responds to the initial transmission will automatically re-use the same
channel as long as the channel remains free of other signals. This allows the radios in the group to
respond more quickly to further transmissions from others in the group.
