TRANSCEIVER PROGRAMMING

after the control channel returns from the Voice On Control mode.

Adjustable Parameters

Busy Override Delay - With SmartZone operation, this is the amount of time a user must press the PTT switch to override a SmartZone busy that occurs because some member of the talk group is present at a site where there are no traffic channels available.

Affiliate Hold Off - With SmartZone operation, this is the delay time that occurs after acquiring the con- trol channel before it sends an affiliation ISW. This prevents all radios on the system from sending affil- iation ISWs at the same time.

Failsoft Inactivity - Programs failsoft operation (see Section 2.5.11). If the radio remains inactive (no receive or transmit activity on channel) while operat- ing in the failsoft mode for the programmed time, the radio momentarily leaves the failsoft mode and attempts to find a control channel. If “0” is pro- grammed, the radio does not leave the failsoft mode.

3.4.5RADIO-WIDE PORTABLE OPTIONS SCREEN

The radio-wide Mobile Options screen is shown above, and is used to program the following parameters (see Section 2.3.6):

Standby Chirp - Selects if a beep sounds every minute while a low battery condition is being detected.

Tx Chirp - Selects if a beep sounds every time the PTT switch is pressed while a low battery condition is being detected.

LED Indicator - Selects if the top panel BAT LED indicates a low battery condition.

3.5PROGRAMMING CONVENTIONAL SYSTEMS AND CHANNELS

3.5.1 INTRODUCTION

The following information describes how conventional channels are programmed. Conventional systems do not need to be set up because only one can be programmed, and it is automatically set up when the programming file is selected as described in Section 3.1.6. Up to 256 conventional channels can be programmed (if no SMARTNET/SmartZone systems are programmed). Refer to Section 1.2.4 for more information on systems and channels.

The following is the recommended procedure for programming conventional channels:

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

2.If other types of systems are programmed, make sure the conventional system is selected by selecting Window > Conventional in the menu bar.

3.Program the conventional system information and then the channel information as follows.
