KNG Mobile Manual
Introduction
Congratulations on your purchase of the BK Radio KNG Mobile radio from RELM
Wireless.
The KNG APCO Project 25 radio offers an array of programmable functionality to
help radio users get the most out of their portable communications. Check with your
RELM/BK Radio dealer or communications ofcer for information on the programmed
functions of your radio prior to operation.
This manual contains information concerning the operation procedures for the BK
Radio KNG Mobile radio. The KNG has been designed to meet the tough requirements
of today’s communications environment. Please take a moment to read the information
in this manual so you can get optimum performance from your new radio.
FCC Requirements
Your radio must be properly licensed by the Federal Communications Commission
prior to use. Your BK Radio dealer can assist you in meeting these requirements. Your
dealer will program each radio with your authorized frequencies, signaling codes, etc.,
and will be there to meet your communications needs as your system expands.

Safety Precautions
Do not operate the transmitter in close proximity to blasting•
caps.
Do not operate the radio in an explosive atmosphere•
(petroleum fuels, solvents, dust, etc.).
Do not operate the transmitter if a person outside the vehicle•
is less than three feet from the antenna or touching the
antenna.
RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION,
AND OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE
REQUIREMENTS
BEFORE USING YOUR MOBILE 2-WAY RADIO, READ THE INFORMATION
BELOW WHICH CONTAINS IMPORTANT OPERATING INSTRUCTIONS FOR SAFE
USAGE AND RF ENERGY AWARENESS AND CONTROL INFORMATION FOR
COMPLIANCE WITH RF ENERGY EXPOSURE LIMITS IN APPLICABLE

KNG Mobile Manual
National and International Standards
NOTICE: This radio is intended for use in occupational/controlled conditions, where
users have full knowledge of their exposure and can exercise control over their
exposure to meet FCC limits. This radio device is NOT authorized for general
population, consumer, or any other use.
This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum
to provide communications between two or more users over a distance. It uses radio
frequency (RF) energy or radio waves to send and receive calls. RF energy is one
form of electromagnetic energy; other forms include, but are not limited to, sunlight
and x-rays. RF energy, however, should not be confused with these other forms of
electromagnetic energy, which when used improperly, can cause biological damage.
Very high levels of x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health and industry work with
organizations to develop standards for exposure to RF energy. These standards
provide recommended levels of RF exposure for both workers and the general
public. These recommended RF exposure levels include substantial margins of
protection. All 2-way radios are designed, manufactured, and tested to ensure they
meet government established RF exposure levels. In addition, manufacturers also
recommend specic operating instructions to users of 2-way radios.
These instructions are important because they inform users about RF energy
exposure and provide simple procedures on how to control it. Please refer to the

KNG Mobile Manual
following websites for more information on what RF energy exposure is and how to
control your exposure to assure compliance with established RF exposure limits.
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov/SLTC/radiofrequencyradiation/index.html
Federal Communications Commission Regulations
The FCC rules require manufacturers to comply with the FCC RF energy exposure
limits for mobile 2-way radios before they can be marketed in the U.S. When 2-way
radios are used as a consequence of employment, the FCC requires users to be
fully aware of and able to control their exposure to meet occupational requirements.
Exposure awareness can be facilitated by the use of a product label directing users to
specic user awareness information. Your BK Radio 2-way radio has an RF exposure
product label. Also, your BK Radio owner’s and service manuals include information
and operating instructions required to control your RF exposure and to satisfy
compliance requirements.
Compliance with RF Exposure Standards
Your BK Radio 2-way radio is designed and tested to comply with a number of
national and international standards and guidelines (listed below) for human exposure

KNG Mobile Manual
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% talk-50% listen 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 antenna radiates measurable RF energy only while it
is transmitting (during talking), not when it is receiving (listening) or in Standby Mode.
Your BK Radio 2-way radio complies with the following RF energy exposure
standards and guidelines:
United States Federal Communications Commission, Code of Federal Regulations;
47 CFR §§ 1.1307, 1.1310, 2.1091 and 2.1093
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
Industry Canada Compliance
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numerique de la classe B est conforme à la norme NMB-003 Canada.

RF Exposure Compliance and Control Guidelines
To control exposure to yourself and others and to ensure compliance with the RF
exposure limits, always adhere to the following procedures.
Guidelines:
User awareness instructions must accompany device when transferred•
to other users.
Do not use this device if the operational requirements described herein•
are not met.
Operating Instructions:
Transmit no more than the rated duty factor of 50% of the time. To transmit (talk),
push the Push-To-Talk (PTT) button. The red LED will illuminate when the radio is
transmitting. To receive calls, release the PTT button. The red LED will extinguish
when the radio stops transmitting. Transmitting 50% of the time, or less, is important
because this radio generates measurable RF energy exposure only when transmitting
(in terms of measuring for standards compliance).
Transmit only when persons around the vehicle are at least 3 feet (90 centimeters)
away from the vehicle with a properly installed antenna. This separation distance will
ensure that there is sufcient distance from a properly installed (according to installation
instructions) externally-mounted antenna to satisfy the RF exposure requirements in
the standards listed above.
