2.2 KEYBOARD PROGRAMMING

GMH Series radios can be programmed in three different ways:

A. With a computer, GMH tuning software, and an LAA 0725 interface cable. That procedure is

not described in this manual.

B. With the optional LAA 0290 keyboard microphone. That procedure is described in this

section.

C. With an LAA 0700 cloning cable, clone programmed settings (except Alphanumeric display

settings) from a BK Radio portable radio with a keyboard and display, and with the same

frequency band as the GMH. That procedure is described on page 2-12.

applicable) by pressing the GRP button and rotating

the Channel Select knob. Press the GRP button
