Scanning (Open Scan /Group Scan); Scan | Mem - Uniden UM255 Owner's Manual

Using Your Radio
Scanning
The UM255 has a scanning feature that allows you to search for active channels
automatically. Furthermore, the UM255 is designed to have two types of scanning;
Open Scanning (OS) and Group Scanning (GS), to give you flexibility and allow you
to use the radio more effectively.
Open Scan Mode (OS)
Allows continuous scanning of all selected channels.
If an active channel is found, scanning will stop on that channel. If the received
signal ceases, the unit will wait 3 seconds for the signal to return, otherwise
scanning resumes.
The scan direction can be changed at any time by pressing a channel key.
After transmission in scan mode, the radio will wait 20 seconds for the signal to
return, otherwise scanning resumes.
To skip the active channel, press any of the channel keys on the base or handset.
Group Scan Mode (GS)
Includes the accessory feature Priority Watch which allows you to monitor the
Instant (Priority) Channel while scanning.
If the Instant (Priority) Channel becomes active the radio will stay on that channel
for as long as the signal is present. If the received signal ceases, GS Scanning
continues after 3 seconds.
If scanning stops on a channel which is not the Instant (Priority) Channel, the
UM255 will continue monitoring the Instant (Priority) Channel for activity while
listening to the active one.
