FCC License required
This Transceiver is intended for use in the operation of commercial
activities.
The Federal Communications commission (FCC) requires you to be
licensed before you
operate this transceiver. Unless you are already licensed to operate
on one of the preset
frequencies, you must apply for a frequency through the PCIA (Personal
Communication
Industry Association), a non-profit organization that assigns
frequencies nationwide to help
prevent conflicts between different businesses using transceivers in
the same area. For
more information about getting a license, contact the PCIA at 800-759-
0300, extension 3068 (in Virginia 703-739-0300, extension 3068)
For other questions concerning the license application, contact the
FCC at 717-337-1212, or wirte: FCC
P.O.Box 1040
Gettysburg, PA 17325

FCC Part 95 Rules
You must be familiar with Part 95 of FCC Rules before you operate your
transceiver. The
operation instructions in this manual conform to Part 95, but do not
cover all items in Part
95.
Overall, Part 95 states that:
! You must have a valid license before you use the transceiver.
! As licensee, you are responsible for proper operation of all
transceivers operating under
your license’s authority.
! You can let unlicensed persons operate transmitter, as long as you
take precautions to
prevent unauthorized transmissions.
! You must use this transceiver only for commercial use of your
business, and only when
other commercial channels (such as the telephone) are either not
available or not
practical.
! You must always yield the operating frequency to communications that
3/16
involve the
safety of life or property.
! You must take reasonable precautions to prevent harmful interference
to other services
operating on the same frequency.
! You must not transmit program material of any kind used in
connection with commercial
broadcasting.
! You must not provide a service that is normally handles by telephone
or telegraph
unless such broadcasts involve the safety of life and property or in
emergencies such
as an earthquake, hurricane, flood or a similar disaster where normal
communications
channels are disrupted.
! During each transmissions or exchange of transmissions, you must
identify your station
with the call sign issued to you by the FCC, or once each 15 minutes
during periods of
continuous operation.
! You must keep a written record of any maintenance or modifications
made to the
transceiver, and you must make this record available for inspection
upon demand by
the FCC.
Violating any of the provisions of Part 95 can result in fines and/or
confiscation of
equipment.
Your transceiver might cause TV or Radio interference even when it is
operating properly.
To determine whether your transceiver is causing the interference,
turn off your transceiver.
If the interference goes away, your transceiver us causing it. Try to
eliminate the
interference by:
! Moving your transceiver away from the receiver
! Contacting your local RadioShack store for help
If you cannot eliminate the interference, the FCC requires that you
stop using your
transceiver.
Before you operate the transceiver, you must obtain your license. It
is illegal to transmit
without the appropriate license, which you can get by submitting a
completed FCC Form
600 to the FCC (or through the PCIA). Furthermore, your are required
to understand Part 95 of the FCC Rules and Regulations prior to
operating your transceiver. It is the user’s
responsibility to see that this unit is operating at all times in
accordance with the FCC Rules
and Regulations.

Safety Information
Your radio contains a low power transmitter. When the PTT button is pushed it sends out radio frequency
(RF) signals. In August 1996, the FCC adopted RF exposure guidelines
with safety levels for hand-held wireless devices.
Cautions:
• To maintain compliance with the FCC’s RF exposure guidelines, hold the entire radio,
including the antenna, at least 2 inches (5 cm) from your face, with the antenna pointed
up and away from your face.
• If you wear the radio on your body, to maintain compliance with the FCC’s RF
exposure guidelines, you must unclip it from your body before transmitting. Hold the
entire radio, including the antenna, at least 2 inches (5 cm) from your body while
transmitting.
• Use only the supplied antenna. Unauthorized antennas, modifications or attachments
could damage the transmitter and may violate FCC regulations.
