SECTION 1 GENERAL INFORMATION

GENERAL INFORMATION

1.1 SCOPE OF MANUAL

This addendum updates current LTR® 9800­series service manuals with information needed to
service 9800-series LTR-Net™ transceivers. The LTR
service manuals it updates are as follows:

984x Series UHF - Part No. 001-9840-202
988x/989x 800/900 MHz - Part No. 001-9880-200
98xx Series UHF/800/900 M Hz - Part No.

001-9800-200 (when available)

1.2 DIFFERENCES BETWEEN LTR AND

LTR-NET VERSIONS

The difference between LTR and LTR-Net
versions of the 9800-series transceivers is the operat­ing software. All electrical and mechanical compo­nents remain the same. Therefore, use this addendum
for Operation and Programming information for LTR­Net models, and use the current sections of your
service manual for Installation, Circuit Description,
Parts List, Schematic Diagram, and PC Board Layout
information.

Different software is used to program LTR and
LTR-Net versions of this transceiver. The LTR-Net
software is a Windows 95/NT program, and the LTR
software is a DOS program. Therefore, either
Windows95 or NT 4 or later is required to program an
LTR-Net transceiver. The part numbers of this soft­ware are shown in Table 1-1.

OPERATION

1. The backlight turns on.

2. All segments of the alphanumeric display are
enabled and the last seven digits of the transceiver
part number (see Section 1.4) are displayed on the
top line very briefly.For example, a 800 MHz, high
tier, LTR-Net, 15-watt transceiver is indicated as
“9883602”. The eighth display digit is reserved for
future use and is always “0”.

3. If there are unread error codes, the last code that
occurred is displayed as “ CODE xx” on t he
bottom line (see Section 2.14).

*

4. A beeps sounds (if tones are enabled) and the trans­ceiver is ready to be used.

2.4.2 DETERMINING VOLUME LEVEL

The relative volume setting can be determined by
noting the position of the index on the volume knob. It
may also be possible to enable a reference tone or
audio for setting the volume level using one of the
following methods:

l If key press tones have been enabled as described in

Section 2.5.15, a short tone can be enabled by rotat­ing the select switch or pressing an option switch.

l If a conventional system is selected, take the micro-

phone off-hook to enable the monitor mode (unless
off-hook detect is disabled). If someone is talking,
audio is then heard. If nobody is talking, the squelch
control can also be adjusted as described in Section

2.4.7 and noise should be heard. Refer to Section

2.11.1 for more information on the monitor mode.
When an LTR-Net or LTR system is selected, the
receiver cannot be manually unsquelched.

2.4.3 BACKLIGHT OPERATION

The display and keypad backlight can be
controlled by the menu BACKLGHT parameter. The
three states that can be selected are Bright, Dim, and
Off. It is in the selected condition whenever power is
turned on. If this menu parameter has been disabled by
programming, the backlight is fixed in one of these
states.

2.4.4 SYSTEM/GROUP DISPLAY
INFORMATION

Up to 99 systems and up to 99 groups per system
can be displayed. Either a numeric or alpha tag display
mode can be selected by the user if the menu S/G
DISP menu parameter is enabled (see Section 2.6.2). If
not, it is fixed by programming.

When the numeric mode is selected, the system
and group numbers are indicated on the top line of the
display as Sxx and Gxx, a nd the group alpha tag (up to
eight characters) is displayed on the bottom line (the
system alpha tag is not displayed). For example,
System 1, Group 1 (CAR 220) is displayed as follows:

System Number

Group Number

Group Alpha Tag

Numeric Display Mode

When the alpha mode is selected, the system
alpha tag is displayed on the top line, and the group
alpha tag is displayed on the bottom line (the system
and group numbers are not indicated). For example, a
“SECURITY” system and “CAR 220” group are
displayed as follows:

System Alpha Tag
Group Alpha Tag

Alpha Display Mode

2.4.5 SELECTING SYSTEMS AND GROUPS

The front panel Select switch is used to change
the system and group. Rotating this switch clockwise
increases the system or group, and rotating it counter­clockwise decreases the system or group. After the
highest system or group is selected, wrap-around to
the lowest system or group occurs and vice versa. The
wrap-around tone sounds when this occurs (if tones
are enabled).

OPERATION

2.7.4 LTR MODE SCANNING

With LTR mode scanning, the home repeater of
each LTR system in the scan list is scanned. Scanning
is sequential through all LTR systems in the scan list.
If several positions are programmed with the same
LTR system, system information is loaded only once.
Therefore, there is no delay to change systems which
results in very efficient scanning of those positions.
Each home repeater is scanned for only as long as
necessary to detect all calls. Priority calls are detected
on LTR systems while scanning (see Section 2.8.1).
LTR systems are not scanned if an LTR-Net system is
selected (see preceding section).

2.7.5 CONVENTIONAL MODE SCANNING

Withconventionaloperation, the channels of each
conventional system in the scan list are s canned in
order. Call Guard squelch is detected if the monitor
mode is disabled (see Section 2.11.1). If the monitor
mode is enabled, all calls occurring on a scanned chan­nel are received. Conventional systems are not
scanned if an LTR-Net system is selected (see Section

2.7.3).

A feature called Adaptive Tone Scan (ATS) is
used when scanning conventional channels. If no
carrier is detected, the channel is scanned for only 40
ms. If a carrier is detected, searching for Call Guard
signaling occurs (if programmed). If the tone type of
Call Guard squelch is programmed, the channel is
monitored for 180-420 ms. The shorter time is when
the tone is outside certain limits, and the longer time is
if it is at or near the programmed value. If digital type
is programmed, approximately 350 m s is required to
determine an invalid code (less time is usually
required to detect valid codes).

switch. If this switch is not programmed, scan list
programming is not available. The scan lists can be
programmed even if scanning is not enabled. The
displayed system is in the scan list and scanned
normally when is displayed, and the displayed
group is in the scan list and scanned normally when

is displayed (see illustration on page 3-14).

The system/group select mode described in
Section 2.4.5 controls if the system or group scan list is
changed when the A/D switch is pressed. If this switch
is pressed with the system select mode enabled, the
status of the displayed system is changed. Likewise, if
it is pressed with the group select mode enabled, the
status of the group is changed. For example, to change
the status of the displayed system, press the Select
switch if necessary so that the system select mode is
indicated and then press the A/D switch.

Deleting a system only temporarily deletes the
groups associated with that system. When a system is
added back into the scan list, the original group scan
list is again active. Systems and groups can be deleted
from the scan list while listening to a message on the
system or group by pressing the A/D switch in the
normal manner. Scanning resumes shortly after the
system or group is deleted.

Saving Current Scan List Changes

The menu SCN SAVE parameter or the default
programming of this parameter determines if changes
to the system and group scan lists are saved. If “ON”
is selected, changes are saved to memory as they are
made and the scan list does not change when power is
cycled. If “OFF” is selected, changes are not saved
and the programmed default status is reselected when
power is cycled.

2.7.6 SCAN LIST PROGRAMMING

NOTES: Calls are always detected on the revert
(selected) system/group while scanning even if it is
deleted from the scan list.

Deleting LTR-Net systems from the scan list also
deletes them from locality searching when roaming
even when scanning is disabled (see Section 2.9.3).

The system and group scan lists are user

programmable using the A/D (add/delete) option

2.7.7 SCAN DELAY AND CONTINUE TIMERS

Receive Delay

When a message is received while scanning, there
is a programmable delay of 0-7 seconds before scan­ning resumes. This delay is called the Receive Delay
Time, and it prevents another message from being
received before a response can be made. This delay is
also in effect if a control is changed while scanning
such as selecting another system/group. This timer is
reset each time another call is received.
