Enhanced Scanning
Scanning is used to:
•Monitor Channels and codes for transmissions and lock in on one that interests you.
•Find someone in your group who has accidentally changed channels and is talking during your scan.
With enhanced scanning, your home channel is scanned more frequently than any other channel. The home channel is the channel your radio was set to when you started to scan. If you activate scan while your radio's Interference Eliminator Code is set to a number between 1 and 99, the radio checks for activity on each channel, but only in the specific code selected. All transmissions using code 0 or any other code are ignored.
To start scanning, briefly press and release 
. The scan indicator 
displays and the radio begins to scroll through the channel and Interference Eliminator Code combinations.
