TRANSCEIVER OPERATION

Answering a Page

1.When a page is received, the display alternately indicates “PAGE RCV” and the alias of the current channel and a recurring received page tone sounds (six beeps) sounds.

2.To clear and ignore the page, press the CLR key. NOTE: If the CLR key is programmed for the Private Call function, it will not clear the page.

3.Answering a page is the same as placing a private call. Therefore, press the Private Call option switch and follow the instructions for placing a private call in Sections 2.5.4 or 2.5.5, whichever is applicable.

2.5.8 MESSAGING

The messaging feature allows preprogrammed messages to be sent to your dispatcher. Up to 16 messages can be preprogrammed, and they are identi- fied by a tag (alias). If a Message option switch is programmed, messages are sent as follows:

2.Enter the index of the desired message if you know

it or scroll through the list using the and keys until you find the desired message. Press the CLR key to cancel the message.

3.Press the PTT switch or the ENT key to send the message. When the message is received and acknowledged by the dispatcher, a signaling success tone (six beeps) sounds and the display returns to the normal channel indication. If there is no acknowl- edgment after 6 seconds, a tone sounds and “NO ACK” is displayed. Press the CLR key to return to normal operation.

2.5.9 SENDING STATUS CONDITIONS

The status feature allows the current status to be sent to a dispatcher. Up to eight status conditions can be preprogrammed, and they are identified by an alias (name). If the Status option switch is programmed, status conditions are sent as follows:

1.Momentarily press the Status option switch. The alias of the last status sent is displayed.

2.To change the displayed status, enter the index of the desired status if you know it or scroll through the list

using the and keys until you find the desired status. Press the CLR key to cancel this function.

3.Press the PTT switch or the ENT key to send the status. When the message is received and acknowl- edged by the dispatcher, a signaling success tone (six beeps) sounds and the display returns to the normal channel indication. If there is no acknowl- edgment after 6 seconds, a tone sounds and “NO ACK” is displayed. Press the CLR key to return to normal operation.

2.5.10 EMERGENCY ALARM AND CALL

Introduction

Emergency Alarms and Calls are separate func- tions that can be individually enabled or disabled on each SMARTNET/SmartZone system. The Emergency option switch is also required for these functions, and it is always the lower button (FCN) on the side when it is used. Emergency Alarms and Calls are transmitted on the emergency talk group programmed on the selected system.

Emergency Alarms

An emergency alarm is a special data transmis- sion that alerts a dispatcher of an emergency situation. Proceed as follows to activate an emergency alarm:

1.Select a SMARTNET/SmartZone channel that has this feature enabled and then press the Emergency option switch. The radio then begins automatically transmitting an emergency alarm data message and “EMERGNCY” is indicated in the display for 3 seconds.

2.When the emergency alarm is acknowledged, the emergency acknowledge tone (two beeps) sounds. Silent operation may also be programmed in which case no tone sounds and there is no indication that an acknowledgment occurred.

3.The radio continues to transmit this message until an acknowledgment is received or the programmed number of attempts have been made. To exit this mode, power must be turned off and then on again.
