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.

All radios in your Net-Scan group must have the same
channels programmed into their Net-Scan memory.

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.
