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 t
he preset frequencies, you must apply for a frequency through the PCIA (Personal
Communication Industry Association), a non-profit organization that assigns frequen
cies nationwide to help prevent conflicts between different businesses using transcei
vers in the same area. For more information about getting a license, contact the PC
IA 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-

FCC Part 95 Rules
You must be familiar with Part 95 of FCC Rules before you operate your transceiv
er. The operation instructions in this manual conform to Part 95, but do not cover a
ll 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 precaution
s 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
3/18
not practical.
! You must always yield the operating frequency to communications that involve th
e safety of life or property.
! You must take reasonable precautions to prevent harmful interference to other ser
vices 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 communi
cations 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 eli
minate the interference by:
! Moving your transceiver away from the receiver
! Contacting your local authorized dealers 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 comple
ted 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 a
ll 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 employment 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 environment.
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 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.
