XPR 4500 / XPR 4550 Mobile Radio
Introduction
Getting Started
The XPR 4500 / XPR 4550 Mobile Radio is among the most sophisticated
two-way radios available. It can operate in the following frequency
ranges:
VHFUHF
136-174 MHz403-470 MHz
450-527 MHz
These channels provide maximum communications capability under
varying operating conditions.
One of the newest in a long line of quality Motorola products, the XPR 4500 /
XPR 4550 Mobile Radio provides improved voice quality
across more of your coverage area. The digital process called
embedded signaling intermixes system signaling information with
digital voice, resulting in improved system reliability and the capability
of supporting a multitude of advanced features. Such features add up
to better, more cost-effective two-way radio communications.
The XPR 4500 / XPR 4550 Mobile radio has two USB ports that can
interface with external devices, such as laptop computers.

Introduction
Identifying Your Radio
The XPR 4500 / XPR 4550 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:
Control Head
The control head has the rotary Volume knob, 4 programmable menu
buttons, menu navigation buttons, menu button, home button, On/Off
button, channel buttons and a 2-line dot matrix LCD display.
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.
Operating Your Control Head
Your advanced control head is designed for ease of use and flexibility
of feature control. Before operating the radio, familiarize yourself with
the various controls, indicators, and alert tones.
•On/Off button: To turn the mobile radio On and Off.
•Rocker Up/Down button: To select the desired position/personality
from the radio.
•Programmable Buttons: Several of the radio’s buttons can be
programmed as short-cut buttons for many of the radio’s features,
P1, P2, P3 and P4.

Introduction
Turning On the Radio
Do the following:
•Turn the radio on with a short press of the power button in
the upper left corner of the control unit.
After a short time, the red, green and yellow LED’s light up,
indicating that the radio is powering up.
The radio first performs a selftest to determine its operational
capability and then powers on
The display then shows XYZ 2345.
When the radio is fully powered on, the Zone and Channel text and
menu items is displayed. The backlight will turn on to the last
selected color and dim level.
Note: Pressing the power button anytime after the LED’s light up
will TURN OFF the radio.
The radio then performs a self check.
Note: If FAIL ##/## appears in the display, the radio will not
function until the condition has been corrected.
If ERROR ##/## appears, some non-critical data has been
changed. If either of these displays appear, if the display
goes blank, or if the unit appears to be locked up, refer to the
“Troubleshooting” section.

Introduction
Trunked Modes or Conventional Channels
Depending on how your radio is programmed, you can select
conventional channels or trunked talkgroup. Conventional channels
consist of a transmit and receive frequency pair, an associated
squelch code pair, and a time-out timer value. See “Conventional
Radio Features” on page 47.
Trunked modes consist of the system/announcement group/talkgroup
combination and a time-out timer value. See “Trunking Operation” on
page 61.
Field Programming
Other radio features may be slaved to the selected mode by field
programming. This mode slaving means that the radio is
preprogrammed to automatically give you the proper operation for
each mode you select.
You may use the control head to program your own mode names.
The names you assign are clearly shown in the alphanumeric display.
You can see all the key operating information, including the mode
selected or being scanned, and the on/off status of various features.
The operating conditions are shown either by the display or by visual/
audio indicators, or by both.
