INTRODUCTION
This section contains information concerning the operational
procedures for BK Radio DMH APCO Project 25 digital mobile radios.

FCC REQUIREMENTS
Your radio must be properly licensed by the Federal Communications

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.

to blasting caps.
• Do not operate the radio in an explosive
atmosphere (petroleum fuels, solvents, dust,
