UNIDEN Model UH400SX,
Operation
Open Scan (OS) Mode
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.
After transmission in scan mode, the unit will wait 20 seconds for the signal to return, otherwise scanning resumes.
To skip the active channel, turn the Rotary Channel Selector at the base or press 
on the Remote SPK/MIC momentarily. To deactivate SCAN, press [SCAN/OS/GS].
If SCAN is deactivated while on an active channel, the UHF CB Radio will stay on that active channel. If no channels are active, the UHF CB Radio will reinstate the starting channel.
OS Mode is indicated by the absence of the GS icon.
Group Scan (GS) Mode
Includes the accessory feature Priority Watch which allows you to monitor the Instant Priority Channel while scanning (see p.20 for setting Instant Priority Channel and p.24 to turn on Priority Watch).
To use GS Mode Scanning, press and hold [SCAN/OS/GS]. GS icon appears on the display.
GS Scanning checks the Instant Priority Channel for activity regularly when Priority Watch is ON.
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, UHF CB Radio will continue monitoring the Priority Channel for activity while listening to the active one.
To deactivate SCAN, press the [SCAN/OS/GS] button.
