Liquid-Crystal Display — 
makes it easy to view and 
change programming 
information. The display 
backlight also makes the 
scanner easy to read in 
low-light situations.

One-Touch Search 
Banks
 — let you search 
preset frequencies in 
separate ham radio, 
police/fire/emergency, 
aircraft, weather, and 
marine banks, to make it 
easy to locate specific 
types of calls.

Priority Channel — lets 
you program a frequency 
into the priority channel. As 
the scanner scans, it 
checks the priority channel 
every 2 seconds so you do 
not miss transmissions on 
that channel.

Tune — lets you tune 
for new and unlisted 
frequencies starting 
from a specified 
frequency.
