TRANSCEIVER PROGRAMMING

2.To program a switch, click the arrow to display the pull-down menu and then select the desired function from that menu. NOTE: Side Button 1 is the top (AUX) button and Side Button 2 is the bottom (FCN) button. Also, the * and # keys are not available with limited keypad (3-key) models.

3.Repeat for all switches and modes to be programmed and then exit this screen by clicking the Close button.

3.4.3 RADIO-WIDE CONVENTIONAL SCREEN

The radio-wide conventional screen is shown above, and it is used to program the DTMF ANI ID. This ID is used on channels programmed for pre- or post-transmit ANI (see Section 3.5.4) and consists of eight digits from 0-9.

3.4.4RADIO-WIDE SMARTNET/SMARTZONE SCREEN

The radio-wide SMARTNET/SmartZone screen is shown above, and is used to program the following parameters:

Full Spectrum CC Scan

In a SmartZone system, if all potential control channel frequencies have been searched, the radio enters a channel-by-channel search across the full spectrum that the radio covers. The timer sets the time it performs this scan before it checks the expected frequencies again. After it checks these frequencies, it returns to full spectrum scanning. This cycle repeats until a control channel is found.

On-Off - Enables or disables full spectrum scan.

Timer - Sets the time that full spectrum scanning occurs as just described.

Hot DTMF

Enable/Disable - When enabled, allows the user to send DTMF tones while transmitting. When dis- abled, pressing numeric keys (0-9, * , #) while transmitting has no affect.

Voice On Control

With SmartZone operation, some remote sites are designated Voice On Control sites. In these sites, if all available traffic channels are occupied, control chan- nels become traffic channels when additional traffic channels are requested. The Voice On Control parame- ters determine how the radio reacts to various situa- tions that may occur. For example, when a conversa- tion is complete, the radio may look for a control channel that has become a traffic channel.

Enable/Disable - Determines if the voice on control parameters are active.

Site Lock Time - This is the amount of time a radio remains on the Voice On Control site before looking for another site.

Activation Time - This is the amount of time the radio waits when the control channel comes back from Voice On Control before it transmits any pend- ing ISWs. This prevents all radios on a Voice On Control site from submitting ISWs at the same time.

Pending Emergency Time - This is the amount of time the radio waits to submit an Emergency ISW
