Uniden UH-088 - Manual (Page 15)

2. Group Scan (GS) Mode
Allows you to monitor a Priority Channel while
scanning.
To use GS Mode Scanning, press the OS / GS key.
GS icon appears on the display. OS Mode is indicated
by the absence of the GS icon.
GS Scanning checks the Priority channel activity
regularly.
If the Priority channel becomes active the radio will
stay on that channel for as long as the signal is present.
If the received signal ceases, Priority scanning
continues after 3 seconds.
If scanning stops on a channel which is not a Priority
Channel, UH-088 will continue monitoring the Priority
Channel for activity while listening to the active one.
eg. CH40 becomes active.
To deactivate SCAN, press the SCAN key or the PTT Switch.
Note: If SCAN is deactivated while it is tuned at an active channel, the UH-088 will
stay on that active channel. If none of the channels are active, the
UH-088 will reinstate the Priority channel.
If GS Scanning is initiated when there are no channels programmed in GS
memory, an error tone will be heard and scanning will not start.
