TRANSCEIVER PROGRAMMING

NOTE: Channel numbers not assigned must be programmed for conventional operation and then not enabled in the above screen because SMARTNET/ SmartZone channels cannot be disabled.

Channel Type

Channel Type Box - Selects the specific system from which the channel is selected. All programmed sys- tems are displayed by number and type (conven- tional, SMARTNET, SmartZone). When a different channel type is selected, the screen for that type of channel is automatically displayed.

System Specific Information - With conventional systems, indicates the frequency of the selected channel without having to select the Modify box.

Transmit Power

Fixes the transmit power on the channel for the high or low level or allows it to be switch selectable (the Hi/Lo Power option switch is then required).

Refer to Section 2.4.10 for more information.

Tx Time-Out

Enables or disables the time-out timer on the channel. The time-out timer time is programmed in the conventional system General screen (Section 3.5.2).

Busy Channel Lockout

Off = disabled, Noise = transmit disallowed if carrier is detected, Tone = transmit allowed with carrier detected only if correct Call Guard (CTCSS/ DCS) code is detected.

Coded Squelch

This sets the transmit and receive Call Guard (CTCSS/DCS) coding, if any, used on the channel. If “None” is selected, no code is transmitted and carrier- controlled squelch is used when receiving (Section 2.4.6). The standard Call Guard tones and codes are listed in Table 3-1 on page 3-22.

Signaling

Off - No ANI signaling is used.

Leading ANI - A DTMF-coded ID is sent at the beginning of each transmission. This ID is set in the radio-wide conventional screen (Section 3.4.3).

Trailing ANI - A DTMF-coded ID is sent at the end of each transmission.

DTMF Enabled - With full keypad (15-key) models, allows manual dialing of numbers using the DTMF keypad.

Channel Modulation

This selects if the channel modulation is wide- band (5 kHz) or narrowband (2.5 kHz).

3.6PROGRAMMING SMARTNET/SMARTZONE SYSTEMS AND CHANNELS

3.6.1 INTRODUCTION

To program SMARTNET and SmartZone systems and channels, proceed as follows:

1.Program the SMARTNET/SmartZone radio-wide information as described in Section 3.4.

2.To create a new SMARTNET/SmartZone system, select the Systems > Add Systems in the menu bar (see Section 3.1.10). Up to sixteen systems of any type can be programmed as described in Section 1.2.4.

3.Program the SMARTNET/SmartZone system infor- mation as described starting in the next section. Make sure the desired SMARTNET or SmartZone system is displayed by selecting it in the Window menu in the menu bar. Then program the channels as described starting in Section 3.6.8.
