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.
