Attenuation

Attenuation can help prevent interference by reducing
the strength of incoming signals. Attenuation can improve
scanning in high-traffic areas, such as large urban areas. In
rural areas, attenuation is used less frequently.
To activate global attenuation, press ATT.

Scanning Legally

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 means of private
telephone signal transmission)
• Paging transmissions
• Any intentionally decoded 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). This
scanner has been designed to prevent reception of illegal transmissions. This
is done to comply with the legal requirement that scanners be manufactured
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 are illegal to monitor. Doing so could
subject you to legal penalties. We encourage responsible, legal scanner use.
In some areas, mobile use of this scanner is unlawful or requires a permit.
Check the laws in your area. It is also illegal in many areas to interfere with
the duties of public safety officials by traveling to the scene of an incident
without authorization.
Warning: Changes or modifications to this unit not expressly approved
by the party responsible for compliance could void the user's authority to
operate the equipment.
Shielded cables must be used with this unit to ensure compliance with the
Class B FCC limits.
