5.2.Scan
Enabling Scan
Press the Scan programmable key to enable Scan and listen to activities on other channels. Press Scan
key again to exit Scan.
Scan List
Each channel can be related to one “Scan List” though dealer programming. The radio can only start Scan
on channels related with “Scan List”. Each “Scan List” contains a maximum of 16 channels (including the
current channel), and both analogue channels and digital channels can be contained. By selecting “Scan
List” menu, you can check the scan channels included in the “Scan List” used by the current channel.
Note:
If the scan channels in the list are changed, other channels which are related with the same list will be
affected during channel scan.
Nuisance (Temporary) Delete
During scan, when the radio stops on an unnecessary channel, e.g. interference channel, it can select
Nuisance Delete to delete this channel before it goes on scanning. You can also add a temporary channel
during scan. After exiting scan mode, the channel which is temporarily deleted or added will turn invalid.
Scanning Revert Channel
During radio scan, press the PTT key to enable the radio to transmit or talk on the preset channel. This
channel can be set by local dealer using programming software.
Prior Scan
If a priority channel is set in a scan list, the channel will be scanned in cycle, i.e. being scanned once before
each common channel is scanned. For example, if a scan list has channels 1, 2, 3 and 4 with channel 2 set
as a prior channel, the scan order will be 1
