Operation

UNIDEN UH785

Handheld UHF-CB Transceiver

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 UH785 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.

NOTE

By default the UH785 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. 

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 Instant Channel (as a Priority Channel) while 

scanning the GS memory (MEM) channels.

See 

Instant Channel Function (Priority Channel),

 page 12 for how to set 

the Priority channel.

NOTE

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.
