INTRODUCTION

This manual contains information concerning the operation procedures
for the BK Radio GPH-CMD radio. The GPH-CMD radio 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.) 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.

FEDERAL COMMUNICATIONS COMMISSION
REGULATIONS

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.
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-

REMOVING THE BATTERY

RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES
AND OPERATING INSTRUCTIONS

1. Turn the radio off.

2. As shown above, push up the metal tab
on the side of the case while twisting the
battery pack approximately 30°.

NOTE: All information programmed into

3. Remove battery pack from the radio.

NOTE: Periodically check the contacts

WARNING: EXPLOSION HAZARD

Do not drop a battery pack into fire.

An explosion may occur.

ANTENNA INSTALLATION

1. Insert the flexible helical -wound antenna
into the radio's antenna connector and turn
it clockwise until it is firmly seated.

the radio is maintained even when
the battery pack is removed.

on the battery pack for dirt that
could prevent a good electrical
contact with the charging base.

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.

• Use only BK Radio approved supplied or replacement antennas,

batteries, and accessories. Use of non-BK Radio approved
antennas, batteries, and accessories may exceed the FCC RF
exposure guidelines.
