Part No. 001-7780-501
This prevents all radios on the system from sending
affiliation 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 oper-
ating 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
programmed, the radio does not leave the failsoft
mode.
3.4.5 RADIO-WIDE MOBILE OPTIONS SCREEN
The radio-wide Mobile Options screen is used to
program the following parameters:
Backlight Level - Selects the default backlight level
whenever power is on. This setting can be over-
ridden by the backlight option switch if it is
programmed.
Hang-Up Box Monitor - Selecting “Off” disables
microphone off-hook detection. Taking the micro-
phone off-hook then does not disable coded squelch
functions or scanning. Selecting “On” enables
microphone off-hook detection.
Ignition Power Down Time - When the ignition
switch controls transceiver power, this sets the delay
that occurs between when the ignition switch is
turned off and when transceiver power actually
turns off. Times of 0-254 minutes can be
programmed or an infinite time (no turn-off) can be
selected (Section 2.3.9).
Minimum Volume - Sets the minimum volume level
that can be selected by the volume control. This can
be used to prevent missed messages caused by inad-
vertently turning the volume down too far. Relative
levels of 0-255 can be set (“0” sets the lowest
minimum volume).
3.5 PROGRAMMING 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 1.5.3 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 in the left
pane or by selecting Window > Conventional in the
menu bar (see Section 3.1.9).
3. Program the conventional system information and
then the channel information as follows.
3.5.2 CONVENTIONAL SYSTEM GENERAL
SCREEN
The conventional system General screen is shown
on the next page, and it programs the following
parameters:
Timers
Tx Time-Out Timer - This timer limits the length of
transmissions (Section 2.3.7). Times up to 3
minutes, 45 seconds in 15-second steps can be
programmed.
