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 UH825 has eight Scan modes;
•
Open Scan (OS)
•
Group Scan (GS)
•
Memory Scan (MS)
•
Preset Scans: P1, P2, P3, P4
Indicated by the SC or GS icon on the LCD. A channel is stored in the
scan memory of the current scan mode when the [M] icon appears
beside the channel number.
By default the UH825 is set to OS scan mode with all UHF-
CB channels stored into the OS channel memory. The GS
scan memory by default is stored with Ch09-20 channels
but can be customized according to User's choice.
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 is the default scane mode which 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?
GS allows you to monitor the default stored channels or the user defined
stored channels along with Priority channel (if enabled) for scanning.
What is Master Scan (MS) Mode?
Master Scan when enabled allow continual communication across
congested channels. Master Scan scans group of different set of
stored channels and only opens the squelch for signals with the correct
subcode (CTCSS or DCS tone).
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.
