Introduction
Congratulations on your purchase of the BK Radio KNG Portable 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 officer 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 Portable 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.
The FCC rules require manufacturers to comply with the FCC RF
energy exposure limits for portable 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 specific user awareness information. Your BK Radio 2-way
radio has a 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 to radio frequency electromagnetic energy.

RELM Wireless Corporation
- 2 -
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. Note: The approved batteries
supplied with this radio are rated for a 5-5-90 duty factor (5% talk - 5%
listen - 90% standby), even though this radio complies with the FCC
occupational RF exposure limits and may operate at duty factors of up
to 50% talk.
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.
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.) unless your radio is an intrinsically safe
model designed for such use.

RF ENERGY EXPOSURE AWARENESS AND CONTROL
INFORMATION, AND OPERATIONAL INSTRUCTIONS FOR
FCC OCCUPATIONAL USE REQUIREMENTS
BEFORE USING YOUR PORTABLE 2-WAY RADIO,
READ THIS IMPORTANT RF ENERGY AWARENESS AND
CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS
TO ENSURE COMPLIANCE WITH THE FCC’S RF EXPOSURE
GUIDELINES.
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 electric power, radar, 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. The energy levels associated with radio
waves from portable 2-way radios, when properly used, are not great
enough to cause biological damage.
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
marketed in North America are designed, manufactured and tested
to ensure they meet government established RF exposure levels. In
addition, manufacturers also recommend specific 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 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.

RF Exposure Compliance and Control Guidelines and Operation
Instructions
To control your exposure and ensure compliance with the occupational/
controlled environment exposure limits always adhere to the following
procedures.
Guidelines:
Do not remove the RF Exposure Label from the device.
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. To receive
calls, release the PTT button. 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).
Hold the radio in a vertical position in front of face with the microphone
(and the other parts of the radio, including the antenna) at least one
inch (2.5 cm) away from the nose. Keeping the radio at the proper
distance is important because RF exposures decrease with distance
from the antenna. Antenna should be kept away from eyes.
When worn on the body, always place the radio in a BK Radio approved
clip, holder, holster, case, or body harness for this product. Using
approved body-worn accessories is important because the use of BK
Radio or other manufacturer’s non-approved accessories may result
in exposure levels which exceed the FCC’s occupational/controlled
environment RF exposure limits.
If you are not using a body-worn accessory and are not using the radio
in the intended use position in front of the face, then ensure the antenna
and the radio are kept at least one inch (2.5 cm) from the body when
transmitting. Keeping the radio at the proper distance is important
because RF exposures decrease with increasing distance from the
antenna.

or zone and goes to the selection indicated by the knob position.
Example: With the channel select knob on channel 1, selecting channel
12 from the keypad will switch the operating channel to channel 12.
Turning the channel knob to channel knob to channel 2, switches the
operating channel to channel 2.
