Introduction

Dual Conversion — helps prevent 
interference from image frequencies.

Your scanner receives these frequencies 
(MHz):

Your scanner might cause TV or radio 
interference even when it is operating 
properly. To determine whether your scanner 
is causing the interference, turn off your 
scanner. If the interference goes away, your 
scanner is causing it. Try to eliminate the 
interference by:

• moving your scanner away from the 

receiver

• connecting your scanner to an outlet 

that is on a different electrical   circuit 
from the receiver

• contacting your local RadioShack store 

for help

If you cannot eliminate the interference, the 
FCC requires that you stop using your 
scanner.

This device complies with Part 15 of the FCC 
Rules. Operation is subject to the following 
two conditions: (1) this device may not cause 
harmful interference, and (2) this device 
must accept any interference received, 
including interference that may cause 
undesired operation. 

Your scanner covers frequencies used by 
many different groups including police and 
fire departments, ambulance services, 
government agencies, private companies, 
amateur radio services, military operations, 
pager services, and wireline (telephone and 
telegraph) service providers. It is legal to 
listen to almost every transmission your 
scanner can receive. However, there are 
some transmissions you should never 
intentionally listen to. These include:

• telephone conversations (cellular, 

cordless, or other private means of 
telephone signal transmission)

• pager transmissions

• any scrambled or encrypted 

transmissions

According to the Electronic Communications 
Privacy Act (ECPA), you are subject to fines 
and possible imprisonment for intentionally 
listening to, using, or divulging the contents 
of such a transmission unless you have the 
consent of a party to the communication 
(unless such activity is otherwise illegal).
