Introduction
Identifying Your Radio
The ASTRO XTL 2500 Digital Mobile Radio has two major
components: the radio unit installed in your vehicle and the control
head that is used to activate various radio features. Keep the foldout
page opened for reference as you read this manual. Your radio has
the following control head:
M5 Control Head
The M5 has the rotary Mode and Volume knobs, 5 programmable
menu buttons, a menu navigation button, and a 3-line, 14-character,
fully bitmapped display (See "M5 Control Head" on page i.).
Note: A "CH MISMATCH" error upon turning on your radio, means
that either the Control Head has been connected to a legacy
transceiver, or vice versa.
