RF Energy Exposure Compliance

Your radio is designed and tested to comply with a number of national and international standards
and guidelines (listed below) regarding human exposure to radio frequency electromagnetic
energy. This radio complies with the IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environment at operating duty factors of up to 50%
transmitting and is authorized by the FCC for occupational use only. In terms of measuring RF
energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF
energy only while it is transmitting (during talking), not when it is receiving (listening) or in
standby mode.

Your radio complies with the following of RF energy exposure standards and guidelines

● United States Federal Communications Commission, Code of Federal Regulations; 47CFR
part 2 sub-part J

● American National Standards Institute (ANSI)/Institute of Electrical and Electronic
Engineers (IEEE) C95. 1-1992

● Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition

● International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998

Safety Information

The following safety precautions shall always be observed during operation, service and
repair of this equipment.

z This equipment shall be serviced by qualified technicians only.
z Do not modify the radio for any reason.
z Use only HYT supplied or approved antenna.
z Gain of antenna must not exceed 3.5dBi for VHF or 5.5dBi for UHF.
z Mobile antenna Installation: Install the mobile antenna at least 100cm (34 inches)

away from your body, in accordance with the requirements of the antenna
manufacturer/supplier.

z Transmit only when people inside and outside the vehicle are at least the minimum

distance away from a properly installed, externally mounted antenna.

z Mobile antenna substitution: Don’t substitute HYT supplied or approved antenna, or

excessive radio frequency radiation will result. Please contact your dealer or the
manufacturer for further instructions.

z Please make sure there’s no stress on the antenna joint during transportation or

installation.

z To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio

in any area where posted notices instruct you to do so. Hospital or health facilities
may be using equipment that is sensitive to external RF energy.

z For vehicles with an air bag, do not place a radio in the area over an air bag or in the

air bag deployment area.

z Turn off your radio prior to entering any area with explosive and flammable materials.
z Do not expose the radio to direct sunlight over a long time, nor place it close to

heating source.

▇ Operation Guidelines

For vehicles equipped with electronic anti-skid braking systems, electronic ignition
systems or electronic fuel injection systems, interferences may occur during radio
transmission. If the foregoing electronic equipments are installed on your vehicle, please
contact your dealer for further assistance to make sure that radio transmission will not
interfere with these equipments.
For radio installation in vehicles fueled by LP gas with LP gas container within interior of
the vehicles, the following precautions are recommended for personal safety.

1. Any space containing radio equipment shall be isolated by a seal from the space in
which the LP gas container and its fittings are located.

2. Remote (outside) fitting connections shall be used.

3. Good ventilation is required for the container space.

▇ Installation Guidelines

z Vehicle installation: The antenna can be mounted at the center of a vehicle metal roof

or trunk lid if the minimum safe distance is observed.

z Do not mount the mobile radio overhead or on a sidewall unless you take special

precautions.

z If the mobile radio is not properly installed, road shock could bump the radio loose,

and the falling radio could, in some circumstances, cause serious injury to the driver
or a passenger. In case of vehicle accidents, even when properly installed, the radio
could break loose and become a dangerous projectile.
