FCC NOTICE

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 conditions: (1) This device
must not cause harmful interference and
(2) this device must accept any interfer-
ence received, including interference
that may cause undesired operation.

SCANNING LEGALLY

Your scanner covers frequencies used
by many different groups including po-
lice and fire departments, ambulance
services, government agencies, private
companies, amateur radio services, mili-
tary operations, pager services, and
wireline (telephone and telegraph) ser-
vice providers. It is legal to listen to al-

most every transmission your scanner
can receive. However, there are some
transmissions you should never inten-
tionally listen to. These include:

• telephone conversations (cellular,

cordless, or other private means of
telephone signal transmission)

• pager transmissions

• any scrambled or encrypted trans-

missions

According to the Electronic Communica-
tions Privacy Act (ECPA), you are sub-
ject to fines and possible imprisonment
for intentionally listening to, using, or di-
vulging the contents of such a transmis-
sion unless you have the consent of a
party to the communication (unless such
activity is otherwise illegal).

This scanner has been designed to pre-
vent reception of illegal transmissions.
This is done to comply with the legal re-
quirement that scanners be manufac-
tured so as to not be easily modifiable to
pick up those transmissions. Do not
open your scanner’s case to make any
modifications that could allow it to pick
up transmissions that it is not legal to lis-
ten to. Doing so could subject you to le-
gal penalties.

We encourage responsible, legal scan-
ner use.
