TRANSCEIVER PROGRAMMING

3.6.2SMARTNET/SMARTZONE SYSTEM GENERAL SCREEN

The SMARTNET/SmartZone System General screen is shown above, and it programs the following parameters:

Restricted Access

Change System ID Button - Displays the Change System ID screen which is used to enter the system ID of the system. This ID is entered as a hexadecimal number from 0-9 and A-F. Valid numbers are from 0001-FFFF. The system ID corresponding to the desired ID must also be located in the “key” subdi- rectory of the program file.

System ID - Read-only field which shows the ID of the system currently being edited.

Splinter Channels

When splinter channels are enabled, the receive and transmit frequencies are 12.5 kHz lower than the normal frequencies. Splinter channels are used only as required in the Mexico and Canada border areas for frequencies between 806 and 820.975 MHz.

Channel Modulation

When “Wideband” is enabled, the radio operates with a 4 kHz maximum deviation between 821.000 and 824.975 MHz and 5 kHz maximum deviation for

all other frequencies. When it is disabled, deviation is 5 kHz with all frequencies.

PTT ID

Enables or disables the PTT ID.

System Lists Button

This button displays the screens used to program the various lists that are unique for each SMARTNET/ SmartZone system. Refer to Section 3.6.7 for more information on these lists.

Dynamic Regrouping

Enable For This System - When this box is checked, a dynamic regrouping channel is enabled. This is a SMARTNET channel which has the corresponding talk group dynamically set by the dispatcher.

Zone - The physical zone containing the dynamic regrouping channel. The value is selected on the Channel Parameters screen.

Channel - The physical channel used for dynamic regrouping. The value is selected on the Channel Parameters screen.

Affiliation Type

Automatic - The radio immediately affiliates with the central controller as soon as it is turned on and auto- matically re-affiliates each time the talk group is changed.

On PTT - The radio affiliates with the central control- ler only when the PTT switch is pressed.

Time-Out Timer

Programs the time-out timer setting for the system. It can be programmed for 0 min, 15 sec up to 3 min, 45 sec or it can be disabled (see Section 2.3.9).

ISW Delay Time

Increasing or decreasing this value changes the transmission timing of ISWs relative to the reception of OSWs.
