Operation
Scanning
The scan feature allows you to search for active channels automatically.
You can only scan channels that are stored in the Scan memory.
The UH220 has two Scan modes (two groups of Scan memory);
•
Open Scan (OS) mode,
•
Group Scan (GS) mode.
Indicated by the OS or GS icon on the LCD. A channel is stored in the
scan memory of the current scan mode when the MEM icon appears
beside the channel number.
By default the UH220 is set to OS scan mode with all
UHF-CB channels stored into the OS channel memory.
The GS scan memory by default is empty - awaiting user
customisation.
NOTE
You can change or customize the channels stored in OS or
GS scan momory by following the steps on Add/Remove
Channels from SCAN Memory on page 18.
What is Open Scan (OS) Mode?
OS scans all memory (MEM) channels in the OS scan memory. If an
active channel is found, scanning will pause on that channel while there
is a signal.
What is Group Scan (GS) Mode?
Allows you to monitor the starting channel (known as the Priority
Channel) while scanning the GS memory (MEM) channels.
If GS Scanning is initiated when there are no channels
programmed in GS scan memory, an error tone will be
heard and scanning will not start.
