Special Considerations for Emergencies

• If you press the emergency button while in a mode that has no emergency capability, a low-pitched tone sounds.

• If the unit is out of the range of the system and/or the emergency alarm is not acknowledged, a tone sounds and the display shows NO ACKNOWLEDGE.

• If you press the emergency button, then change to a mode that has no emergency capability, a NO EMERGENCY display alternates with the mode name display, and a continuous low-pitched tone sounds until a valid emergency mode is selected or until the emergency is cancelled.

• When an emergency is active, changing to another mode where emergency is enabled (trunked or conventional) causes an emergency alarm and/or emergency call to be active on the new mode.

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.



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).



A solidly-lit PRI (priority) indicator means that the active mode is the priority 2 member of the scan list (Trunking Priority Monitor and Conventional scan types only).



Notes

Troubleshooting

The following are suggestions to assist you in troubleshooting possible operating problems.

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.

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.

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 PrivateLine (DPL) Coded Squelch

Dispatcher An individual who has radio system

communicate in a non-trunked, conventional mode should the trunked system fail.

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.

XPR 4500 / XPR 4550 Mobile Radio

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

A continuous sub-audible tone transmitted with the carrier.

Squelch

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.
