XPR 4500 / XPR 4550 Mobile Radio

General Radio Features

Scan Operation

The scan feature allows you to monitor activity on different

conventional or trunked modes by scanning a scan list of modes. The

modes to be scanned in a scan list are programmed by a qualified

radio technician. You can select the modes to be scanned in a scan

list if operator-selectable scan is enabled.

There are three types of scan lists available:

• Conventional—Comprises up to 15 different conventional-only

modes

• Trunked Priority Monitor—Comprises up to 15 modes that are all

from the same trunked system

• Talkgroup Scan—Comprises up to 10 combined conventional

modes and modes from one trunking system

The radio supports both priority and non-priority scanning. With

priority scanning enabled, a scan list can have one mode assigned as

the first-priority mode and a second as the second-priority mode.

The XPR 4500 / XPR 4550 Mobile Radio supports automatic scanning

(autoscan), which can be programmed into the radio by a qualified

radio technician. With this feature, the radio begins scanning

whenever you select a mode to which a scan list is assigned.

Note: You cannot turn scan off on a mode that has autoscan

enabled.

If multiple scan types are enabled in the radio, the type of scan that is

activated depends on the personality of the mode selected when the

SCAN softkey is pressed. For all types of scan, the selected mode is,

by default, a member of its own scan list.

Scan lists stay in memory when you turn scan off, turn the radio off, or

disconnect the radio from the battery.

General Radio Features

Turning On Scan

Do the following:

1Press the  button to scroll to the SCAN softkey.

2Press the button below SCAN.



The Scan indicator lights and a list of modes is scanned

for activity. The text display area will indicate SCAN ON if

scan is currently enabled or SCAN OFF if scan is just

been turned off.



When a scanned mode becomes active, the display

changes to show the active mode name, the appropriate

priority indicator lights, and the radio unmutes.



The radio will not begin scanning again for a

predetermined hang time after the call ends, giving you

time to respond. The hang time is typically three

seconds (by default), but can be changed by a qualified

radio technician.

Note: A lit N PRI (non-priority) indicator means that the active

mode is a non-priority member of the scan list (for all scan

types).

Troubleshooting

The following are suggestions to assist you in troubleshooting

possible operating problems.

If your radio is locked up or the display shows FAIL 01/90, turn the

radio off and then back on. If this does not correct the condition, take

the radio to a qualified radio technician for service.

If radio operation is intermittent, check with other persons using the

system for similar problems before taking the radio in for service.

Similar problems indicate a system malfunction rather than a radio

failure.

If symptoms persist or, if your unit exhibits other problems, contact a

qualified radio technician.

The cables that connect to the rear of

the radio could have live voltage on

some of their pins. Do not remove or

reconnect these cables. Only a

qualified radio technician should

perform this task. Service performed

by unauthorized personnel may cause

the radio to transmit an emergency

alarm even if the unit is turned off.

Glossary

ACK Acknowledgment of communication.

Channel A group of characteristics, such as transmit/

receive frequency pairs, radio parameters, and

encryption encoding.

Coded Squelch Tone Private-Line™ or Digital Private-Line.

Used on conventional channels to make sure

you hear only the communication meant for

you.

Control Channel In a trunking system, one of the channels that

is used to provide a continuous, two-way/data

communications path between the central

controller and all radios on the system.

Conventional Typically refers to radio-to-radio

communications, sometimes through a

repeater. You share a frequency, or

frequencies, with other users without the aid of

a central controller to assign communication

channels. Therefore, you should monitor each

channel before transmitting to avoid interfering

with another user who may be transmitting.

Cursor A visual tracking marker (a blinking line) that

indicates a location on the display.

Digital Private-

Line (DPL) Coded

Squelch

A continuous, sub-audible data signal,

transmitted with the carrier.

Dispatcher An individual who has radio system

management duties.

Failsoft A back-up system allowing you to

communicate in a non-trunked, conventional

mode should the trunked system fail.

FCC Federal Communications Commission.

XPR 4500 / XPR 4550 Mobile Radio

Glossary

Hang Up Disconnect.

Home Display The first display information after the radio

completes its self test.

LCD Liquid-Crystal Display.

Mode A programmed combination of operating

parameters; for example, a channel or

talkgroup.

Mode-Slaving Radio programmed to automatically give the

proper operation for a given mode you have

selected.

Monitoring

(Conventional

Operation)

Press a programmed monitor button to listen to

another user active on the channel. This way,

you may be prevented from talking over

someone else’s conversation.

Page A one-way alert, with audio and/or display

messages.

Push-To-Talk

(PTT) button

The PTT button engages the transmitter and

puts the radio in transmit (send) operation

when pressed. Press this button to transmit;

release it to receive.

Repeater A conventional radio feature, in which you talk

through a receive/transmit facility (repeater)

that re-transmits received signals in order to

improve communications range and coverage.

RF Radio Frequency. A part of the general

frequency spectrum between the audio and

infrared light regions (about 10 kHz to

10,000,000 MHz).

RSSI Received Signal Strength Indicator.

Glossary

Squelch The muting of audio circuits when received

signal levels fall below a pre-determined

threshold. With carrier squelch, you hear all

channel activity which exceeds the radio’s

preset squelch level.

Standby An operating condition whereby the radio’s

speaker is muted but still continues to receive

data.

Talkgroup An organization (or group) of radio users who

communicate with each other, using the same

communication path.

Tone Private-Line

(PL) Coded

Squelch

A continuous sub-audible tone transmitted with

the carrier.

Trunking The automatic sharing of communications

paths between a large number of users (see

Conventional). Allows radio users to share a

smaller number of frequencies because a

repeater, or communications path, is assigned

to a talkgroup for the length of a conversation.

Zone A grouping of channels or talkgroups.
