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 fequencies, 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 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
transceivers operating under your license’s authority.
of
all
! 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
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
connection with commercial broadcasting.
of
any
kind
used
in
! 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
2/16
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 Handheld Radio generates RF electromagnetic energy during transmit mode. This radio is
designed for and classified as “ Occupational Use Only”, meaning it must be used only during the
course of employme nt by individuals aware of the hazards, and the ways to minimize such hazards.
This radio is NOT intended for use by the “General Population” in an uncontrolled environme nt.
This radio has been tested and complies with the FCC RF exposure limits for “Occupational Use Only.”
In addition, your Handheld radio complies with the following Standards and Guidelines with regard to RF
energy and electromagnetic
energy levels and evaluation of such levels for exposure to humans:
• FCC OET Bulletin 65 Edition 01-01 Supplement C, Evaluating Compliance with FCC Guidelines for
Human Exposure to Radio Frequency Electromagnetic Fields.
• American National Standards Institute (ANSI) (C95.1—1992), IEEE Standard for Safety Levels with
Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
• American National Standards Institute (C95.3—1999), IEEE Recommended Practice for the
Measurements of Potentially Hazardous Electromagnetic Fields — RF and Microwave.
To ensure that your exposure to RF electromagnetic energy is within the FCC allowable limits for
occupational use, always adhere to the following guidelines:
DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also
3/16
cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with the radio by
the manufacturer or an antenna specifically authorized by the manufacturer for use with this radio.
For body worn operation, this handheld radio has been tested and meets the FCC RF exposure guidelines
when used with the TTI or authorized OEM dealers accessories supplied or designated for this product.
Use of other accessories may not ensure compliance with FCC RF exposure guideline.
To provide the recipients of your transmission the best sound quality, hold the antenna at least 2.5 cm (1
inch) from your mouth.
USE ONLY authorized accessories (speaker/microphones, handstraps, etc.) with your radio. Use of
unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded.
The information listed above provides the user with the information needed to make him or her
aware of RF exposure, and what to do to assure that this radio operates within the FCC RF
exposure limits of the radio.
ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
During transmissions, your handheld radio generates RF energy that can possibly cause interference with
other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to
do so.
DO NOT operate the transmitter in areas sensitive to electromagnetic radiation, such as hospitals,
aircraft, and blasting sites.
CAUTIONS:
• NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body
while transmitting. The transceiver will perform best if the microphone is 2.5– 5 cm (1 to 2 inches) away
from the mouth and the transceiver is vertical.
• For body worn operation, this handheld radio has been tested and meets the FCC RF exposure
guidelines when used with the TTI or authorized OEM dealers accessories supplied or designated for this
product. Use of other accessories may not ensure compliance with FCC RF exposure guideline.
• DO NOT push the PTT when not actually desiring to transmit.
