TRANSCEIVER OPERATION

•To turn radio wide scanning off, press the Radio

Wide Scan option switch again. The icon is then no longer indicated and “RWS OFF” is displayed briefly.

•If the zone or channel is changed while radio wide scanning, radio wide scanning continues normally.

Scan Resume Delay

When a message is received or transmitted while scanning, there is a programmable delay before scan- ning resumes. The delay after receiving a call prevents another message from being received before a response can be made, and the delay after transmitting a call ensures that a response is heard to your call instead of another message occurring on some other channel.

Standard Mode Scan List

NOTE: The selected channel is always scanned.

With conventional operation when using the full keypad (15-key) model, up to three scan lists can be programmed. The list that is scanned is selected by the Scan option switch as described in Section 2.4.11. Selecting another conventional channel does not change the current scan list. In addition, the scan lists are user programmable if the Scan Edit option switch is programmed. With limited keypad (3-key) models, only Scan List 1 can be scanned, and it is not user programmable.

With SMARTNET/SmartZone operation, each channel can be programmed so that one of up to three different scan lists is automatically selected. Channels can also be programmed so that scanning is automati- cally disabled when they are selected. SMARTNET/ SmartZone scan lists are not user selectable or programmable.

Radio Wide Mode Scan List

With radio wide scanning, there is only one preprogrammed scan list available regardless of the type of channel selected, and it is not user programmable.

Determining Which Channels are in Scan List

Channels in the radio wide and standard SMARTNET/SmartZone scan lists are not indicated. With standard conventional scanning, the selected

channel is in the current scan list if the box icon (around “ S”) is indicated in the upper left corner of the display.

Nuisance Channel Delete

With standard scanning, both conventional and SMARTNET/SmartZone channels can be temporarily deleted from the scan list. This feature is not available with radio wide scanning. Proceed as follows:

NOTE: The selected channel and conventional priority channels cannot be deleted from the scan list.

1.While receiving a message on the channel to be deleted, press and hold the Scan option switch until the alert tone sounds (about 1 second).

2.The channel is then deleted and scanning of the remaining channels in the scan list resumes.

3.Deleted channels are added back into the scan list if either of the following occur:

•Scanning is turned off and then on again using the Scan switch.

•Transceiver power is turned off and then on again.

2.3.12CONVENTIONAL AND SMARTNET/ SMARTZONE OPERATION

Introduction

Each selectable channel is programmable for

either conventional, SMARTNET, or SmartZone oper- ation. For example, Zone 1/Channel 1 could be a conventional channel, Zone 1/Channel 2 a SMARTNET channel, and so on. More information on these modes follows.

Conventional Operation

This is a non-trunked operating mode which

accesses independent radio channels (there is no auto- matic access to several channels as with trunked oper-
