FCC Notice

This equipment has been tested and found to comply with the limits
for a scanning receiver, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
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.

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 private
means of telephone signal transmission)
• Pager transmissions
• Any scrambled or encrypted transmissions
58
According to the Electronic Communications Privacy Act (ECPA),
as amended, 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 is designed to prevent reception of illegal transmissions,
in compliance with the law which requires that scanners be
manufactured in such a way 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 not
legal to listen to. Doing so could subject you to legal penalties.
In some areas, mobile use of this scanner is unlawful or requires a
permit. Check the laws in your area. We encourage responsible, legal
scanner use.

Key Terminology

Alpha tag Alpha-numeric object name displayed on the LCD
that can be specified by a user.
Attenuator
Reduces interference due to intermodulation.
Backlight Illuminates the LCD and/or keypad for night time
use.
Channel See "Object"
CTCSS/DCS Continuous Tone-Coded Squelch System/Digital
Coded squelch System, a squelch control system
which reduces interference when using the same
frequency.
EDACS Trunking system technology provided by GE/Erics-
son/MA-COM or Harris.
Image Frequency Undesired frequency that differs from the required
received frequency.
Intermodulation Occurs when two or more strong signals mix, which
generates a "false" frequency such as image fre-
quency and distorts receiving sound.
LTR E.F. Johnson's trunking system.
