About Your Scanner
Understanding Banks
Service Banks
The scanner is preprogrammed with all the 
frequencies allocated to the weather, ham, marine, 
aircraft, police, and fire services.
Channel-Storage Banks
To make it easier to identify and select the channels 
you want to listen to, the 100 channels are divided 
into 10 channel-storage banks. Each bank has 10 
channels. Use each channel-storage bank to group 
frequencies, such as those for the police 
department, fire department, ambulance services,...

Close CallTM RF Capture Technology
Your scanners Close Call feature lets you set the 
scanner so it detects then displays the frequency of 
a nearby strong radio transmission. Close Call RF 
capture works great for finding frequencies at 
venues such as malls and sporting events. You can 
set the scanner so Close Call detection works in the 
background while you are scanning other 
frequencies, turn off normal scanning while Close 
Call is working, or turn off the...

Special Features
• Close Call works better with some types of 
transmissions than others. It might not correctly

same area, or if the transmitter is a broadcast 
television station.
