INTRODUCTION

CONGRATULATIONS, you now own a BK Radio GPH Plus radio. This

enhanced GPH portable radio has 400 channels; whereas, the

standard GPH series had a maximum of 240 channels. Like the

standard GPH, the Plus 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.
