each new frequency replaces a frequency 
previously stored, beginning with the first stored 
frequency.
•Press Func +   or Func +   to select a 
skipped frequency while Hold appears. L/O 
appears when you select a skipped frequency.
Delay
Sometimes a user might pause before replying to a

2 seconds after the transmission stops before 
resuming scanning or searching. The scanner 
automatically sets a delay when you store 
frequencies into channels or when you search 
frequencies. When the delay feature is on, DLY 
appears. If it is off, follow one of these steps to 
program a delay depending on how the scanner is 
operating,.
• If the scanner is scanning and stops on an active 
channel where you want to store a delay, quickly
