GENERAL INFORMATION
SECTION 1 GENERAL INFORMATION
1.1 SCOPE OF MANUAL
This service manual contains alignment and
service information for the E.F. Johnson 5100-Series
portable digital transceivers.
1.2 TRANSCEIVER DESCRIPTION
1.2.1 GENERAL
The 5100-series portable digital transceivers have
multiple system select capability to allow operation in
various types of radio systems (see next sections).
Models are available for operation in the following
frequency range: 806-870 MHz.
Repeater talk-around, which allows transmitting
on the receive frequency, is also available
with all bands.
Power output is user switchablefor lowand high levels
as follows:
800 MHz - 3 watts only
1.2.2 ANALOG/DIGITAL OPERATION
The 5100-series transceivers use a digital signal
processor (DSP) to provide the signal modulation
required to operate on the following types of channels.
This provides backwards compatibility with existing
equipment and also the ability to operate on various
types of radio systems.
Wideband Analog - FM modulation is used with a
maximum deviation of 5 kHz. This mode is usually
used in systems where the channel spacing is 25 kHz
or 30 kHz.
Project 25 Digital - Operates on Project 25 compatible
systems. The voice is digitized, error corrected,
optionally encrypted, and then transmitted using
C4FM modulation according to the Project 25 stan-
dard. This mode uses a channel spacing of 12.5 kHz.
1.2.3 OPERATING PROTOCOLS
The 5100-series transceivers can be programmed
for all the following operating protocols. Refer to
Section 2 for more operation information.
•Conventional analog
•Conventional Project 25 (digital)
•Trunked Project 25 (digital)
•SMARTNET’/SmartZone®analog or Proj 25
(digital)
•Multi-Net®trunked (analog)
1.2.4 18-KEY/6-KEY MODELS
Both 18-key and 6-key models are available. The
18-key version includes number keys 0-9 for making
telephone calls, entering unit or group ID numbers,

1.2.5 SYSTEMS, CHANNELS, AND ZONES
A zone and channel are selected to place and
receive calls. The following describes the relationship
between systems, channels, and zones.
Systems
A system as used with this transceiver is a collec-
tion of channels (talk groups) belonging to the same
repeater site. A system defines all the parameters and
protocol definitions required to access a site. Up to
1 conventional system and 15 SMARTNET/
SmartZone systems can be programmed (16 total).

GENERAL INFORMATION
1-2 September 2001
Part No. 001-5100-001
hannels
A channel selects a radio channel or talk group in
a system as follows:
Conventional Analog Mode - A channel selects a
specific radio channel, all Guard ( T SS/D S)
squelch coding, and other parameters unique to that
channel.
Conventional Project 25 Mode - A channel selects a
specific radio channel, NA squelch coding, and other
parameters unique to that channel.
SMARTNET/SmartZone Operation - A channel
selects a specific talk group, announcement group,
emergency group, and other parameters unique to that
channel.
A maximum of up to 256 channels can be
programmed with the preceding modes. The conven-
tional system can be programmed with up to 256 chan-
nels, and each of the SMARTNET/SmartZone systems
can be programmed with up to 256 talk groups
(channels).
Therefore it is theoretically possible to program
any combination of these systems that produces up to
256 total channels. However, the maximum number
may be limited by the available memory. For example,
since more memory is required to program a
SMARTNET system than a conventional system, the
total number of channels decreases as the number of
SMARTNET systems increases. The programming
software displays a bar graph which shows the amount
of available memory space that is used by the current
data. Refer to Section 3.1.10 for more information.
Zones
A zone is a collection of up to 16 channels of any
type (conventional or SMARTNET/SmartZone). For
example, a zone could include 12 conventional chan-
nels and 4 SMARTNET channels. Zones are similar to
banks used in other E.F. Johnson transceivers. One use
of zones may be to program the channels used for
operation in a specific geographical area. Up to 16
zones can be programmed.
1.2.6 SECURE COMMUNICATION
Secure communication is available with all the
preceding protocols. The following types of encryp-
tion are available:
onventional Analog and SMARTNET/SmartZone
Operation
•460 Scrambling (Transcrypt)
onventional Project 25 Operation
•DES-OFB
1.2.7 PROGRAMMING
Transceiver programming is performed using a
P -compatible computer and an E.F. Johnson 5100
series programming cable and P Trunk™ program-
ming software (see Table 1-1). Programming is
described in Section 3.
1.2.8 ALIGNMENT
Transceiver alignment is performed using the
same computer and cable used for programming (see
preceding section). In addition, special P Tune™
software, the Radio Interface Box (RIB), and a
computer cable are required. All adjustments are made
using the software (no manual adjustments are
required). Refer to Section 5 for alignment
information.

2.4 GENERAL OPERATION
2.4.1 INTRODUCTION
The following section describes features available
with both trunked and conventional operation.
Features unique to conventional channels are
described in Section 2.6, and features unique to
SMARTNET/SmartZone channels are described in
Section 2.7.
2.4.2 TURNING POWER ON AND SETTING
VOLUME
Power is turned on and off by the On-Off/Volume
switch on the top panel. When power is initially turned
on, an alert tone sounds and the indicator on the top
panel flashes green. If a SMARTNET/SmartZone
channel is selected, the zone alias is then displayed
followed by the unit ID (see Section 2.7.2). The
selected channel is then indicated.
To turn power off, turn the On-Off/Volume knob
counterclockwise until a click occurs. The display may
remain on for a few seconds after power is turned off.
It is recommended that power not be turned back on
again until the display is blank.
The relative volume level can be determined by
noting the position of the index on the On-Off/Volume
knob. To enable a reference tone for setting the
volume, proceed as follows:
•If key press tones are enabled (see Section 2.4.11), a
short tone sounds when front panel keys are pressed.
•If a conventional channel is selected and the
Monitor option switch is programmed (see Section
2.6.4), pressing that switch unsquelches/squelches
the receiver and either voice or background noise is
heard. If a SMARTNET/SmartZone channel is
selected, the receiver cannot be manually
unsquelched.
2.4.3 POWER-UP PASSWORD
General
The power-up password feature prevents unau-
thorized use of the transceiver. When it is enabled by
system operator programming, an eight-digit password
must be entered to make the transceiver operational
each time power is turned on. Passwords can be
entered even if the keypad is locked (see Section
2.4.6). The default password is eight zeros
(00000000). Refer to Section 3.7 for more informa-
tion on passwords.
If this feature is enabled, proceed as follows to
unlock the radio:
1. Turn radio power on and when “LO KED” is dis-
played, enter the eight-digit numeric password
using the keypad. As each digit is entered, a dash is
displayed. If an incorrect digit is entered, press the
CLR key and re-enter the entire password.
2. When all eight digits have been entered, press the
ENT key. If the password is correct, the display
indicates normal zone and then channel informa-
tion. If an incorrect password is entered,
“LO KED” is again displayed.
hanging Password
The current password can be changed as follows:
1. The locked mode must be selected to change the
password, so cycle power if necessary to display
“LO KED”.
2. Enter the old eight-digit password and press the #
key (not ENT). If the correct password is entered,
“NEW PSWD” is displayed.
3. Enter the new password and press ENT. The pass-
word is changed.
2.4.4 BACKLIGHT
The backlight for the display and keypad can be
manually turned on by pressing the Backlight option
switch if it is available. The backlight can also be
system operator programmed to automatically turn on

The programmable option switches are as
follows:
•F1, F2, F3, and F4 on front panel. In addition, with
full keypad (18-key) models, the # key is program-
mable (see Figure 2-1).
•The two push-button switches on the side panel (see
illustration in Section 2.3.3).
•The 3-position toggle switch on the top panel (see
Figure 2-2).
If your radio is programmed with both conven-
tional and SMARTNET/SmartZone channels (see
Section 2.4.12), these option switches can be system
operator programmed to control a different set of func-
tions for each channel type. For example, the F1
switch could select Hi/Lo Power when a conventional
channel is selected and Private alls when a
SMARTNET/SmartZone channel is selected. The
available functions in each mode are indicated in the
tables in Section 2.2. If no option switch has been
programmed to control a particular function, that func-
tion may not be available or may be in a fixed mode.
2.4.6 KEYPAD LOCK
If the Keypad Lock option switch has been
programmed, the keypad can be locked (disabled) to
prevent keys from being accidentally pressed. To lock
the keypad, simply press this switch. Then to unlock it
again, press and hold it until a tone sounds. The
keypad can also be disabled by system operator
programming. It is then permanently disabled and
cannot be re-enabled by the user.
2.4.7 LOW BATTERY INDICATION
When the battery voltage falls below a preset
level, the radio can be programmed so that any or all
of the following indications occur:
•The indicator on the top panel flashes red in the
transmit mode and green in the receive mode.
•A chirp sounds every 5 seconds in the receive mode.
•A chirp sounds every 5 seconds in the transmit
mode.
The battery should be recharged as soon as prac-
tical after a low battery indication appears.
2.4.8 CHANNEL AND ZONE SELECTION
hannel Select
To change the current channel, rotate the 16-
position channel selector knob on the top panel to the
desired position. With SMARTNET/SmartZone chan-
nels, the selected channel is always indicated by an
alias (name). The alias is also displayed with conven-
tional channels if the Display Mode option switch is
not programmed. If this switch is programmed, the
channel number or frequency may also be displayed
(see Section 2.6.2).
Zone Select
A zone is a group of up to any 16 conventional
and SMARTNET/SmartZone channels defined by
system operator programming. Up to 16 zones can be
programmed for a total of 16 x 16 channels per zone or
256 channels. One use of zones may be to select
groups of channels programmed for operation in
different geographical areas or radio systems. If select-
able zones have been programmed in your radio,
consult your system operator for more information on
how they are used. Zones are selected as follows:
1. Press the Zone option switch and the alias (name) of
the current zone is flashed in the display.
2. Use the number keys to enter the desired zone
number or scroll through the available zones using
the and keys.
3. When the desired zone is displayed or entered,
select it by pressing the ENT key or waiting 4
seconds.

Part No. 001-5100-001
2.4.9 HOME ZONE
The radio can be programmed with a home zone.
Then when power is turned on, the radio can be
programmed so that either the home or last selected
zone is automatically selected.
If the Home Zone option switch is programmed,
it can be used to quickly select or change the home
zone. To select the home zone, simply press this
switch. To change the home zone to the currently
selected zone, press and hold this switch until a tone
sounds (approximately 1 second).
2.4.10 TIME-OUT TIMER
The time-out timer disables the transmitter if it is
keyed for longer than the programmed time. It can be
programmed on each channel for times of 15 - 225
seconds or it can be disabled (not used). If the trans-
mitter is keyed continuously for longer than the
programmed time, the transmitter is disabled and an
invalid condition tone sounds. Five seconds before
time-out occurs, an alert tone sounds to indicate that
time-out is approaching. The timer and tone are reset
by releasing the PTT switch.
One use of this feature is to prevent a channel
from being kept busy for an extended period by an
accidentally keyed transmitter. It can also prevent
possible transmitter damage caused by transmitting for
an excessively long period. onventional channels can
also be programmed with the Penalty and onversa-
tion timers that are described in Sections 2.6.7 and
2.6.8.
2.4.11 TONE ENABLE/DISABLE
The supervisory tones (see Section 2.8) can be
enabled and disabled by the Tones On-Off option
switch if it is programmed. When tones are enabled by
this switch, “TONE ON” is momentarily displayed
and a tone sounds. onversely, when tones are
disabled, “TONE OFF” is displayed and no tone
sounds. If the Tones On-Off option switch is not
programmed, tones are fixed in the on or off mode by
programming.
2.4.12 TRANSCEIVER OPERATING MODES
Introduction
Each selectable channel can be programmed for
either the conventional or SMARTNET/SmartZone
operating mode. For example, Zone 1/ hannel 1 could
be a conventional channel, Zone 1/ hannel 2 a
SMARTNET channel, and so on. More information on
these modes follows.
onventional Mode
This is a non-trunked operating mode which
accesses independent radio channels (there is no auto-
matic access to several channels). Monitoring before
transmitting may not be automatic in this mode, so you
may need to manually monitor the channel before
transmitting to make sure that it is not in use. Either
analog or digital (Project 25) signaling may be used.
When a digital channel is selected, “DIG” is indicated
in the upper part of the display. hannel monitoring
and other operating features unique to conventional
channels are described starting with Section 2.6.1.
SMARTNET™/SmartZone® Mode
This is a trunked operating mode that uses ID
codes to select what mobiles are being called and what
calls are received. Monitoring is performed automati-
cally and special messages and tones indicate busy and
out-of-range conditions. Enhanced features include
roaming (SmartZone only), telephone, private, and
emergency calls, all Alert™, and messaging. Either
analog or digital signaling may be used. When a
digital channel is selected, “Dig” is indicated in the
upper part of the display. Operating features unique to
SMARTNET/SmartZone channels are described
starting with Section 2.7.1.
When a SMARTNET or SmartZone channel is
selected or the radio is powered up on one of those
channels, it searches for a control channel and
attempts to register on the radio system. Once a
control channel is found, the alias (name) of the
selected channel is displayed. If a control channel
could not be found (because of an out of range condi-
tion or the system ID is not correct, for example), “NO
SYS” is displayed and the radio continues to search
for a control channel.

OPERATION
2-8 September 2001
Part No. 001-5100-001
The control channel transmits and receives
system information to and from all radios registered on
the system. Therefore, once a control channel is found,
it is continuously monitored for incoming call infor-
mation and is used to make call requests. The radio
automatically changes to a traffic channel to place and
receive calls and then returns to the control channel
when the call is complete.
2.4.13 SECURE COMMUNICATION
This transceiver may be optionally equipped to
provide secure communication on some or all chan-
nels. This feature encrypts your voice so that it can be
understood only by someone using a transceiver
equipped with a similar encryption device and encryp-
tion codes.
When a secure call is received or transmitted,
“Sec” is indicated in the upper part of the display.
Secure communication can be programmed on a per
channel basis to operate in various ways. If equipped
with the lear/Secure option switch and the current
channel is programmed to allow switch selection,
secure communication can be manually enabled and
disabled by that switch. Secure communication can be
programmed on a per channel basis to operate in
various ways. Refer to Sections 2.6.17 and 2.7.15 for
more information.
2.5 SCANNING
2.5.1 INTRODUCTION
Scanning cycles through a list of channels called
a “scan list”, checking each for messages. When a
message is detected that your transceiver is
programmed to receive, scanning stops and the
message is received. Shortly after the message is
complete, scanning resumes (unless it has been
disabled).
There are two basic scan modes: Standard and
Radio Wide. The Standard mode is unique to the type
of channel selected (conventional or SMARTNET/
SmartZone), and the Radio Wide mode is the same
regardless of the channel type selected. Only one of
these scan modes can be enabled at a time. Therefore,
if standard scanning is enabled while radio wide scan-
ning is occurring, radio wide scanning is automatically
disabled and vice versa. More information on these
modes follows.
2.5.2 STANDARD SCANNING
Standard scanning monitors only channels that
are the same type as that currently selected. There-
fore, if a conventional channel is selected, only
conventional channels are scanned, and if a
SMARTNET channel is selected, only SMARTNET
channels are scanned. Standard scanning is turned on
and off by the Scan option switch as follows. If this
switch is not programmed, standard scanning is not
available.
•To turn standard scanning on, press the Scan option
switch. Scanning is enabled when the “Scan” icon
is indicated in the upper right corner of the front
panel display and “S AN ON” is briefly displayed.
•To turn scanning off, press the Scan option switch
again. The “Scan” icon is then no longer indicated
and “S AN OFF” is briefly displayed.
•If the zone or channel is changed while scanning is
selected, scanning continues on the same or a
different scan list (see scan list information which
follows).
2.5.3 RADIO WIDE SCANNING
Radio wide scanning monitors the channels in the
preprogrammed radio wide scan list (see Section
2.5.5). This list may contain up to 16 channels of any
type (conventional or SMARTNET/SmartZone)
assigned to any zone. Radio wide scanning is turned
on and off by the Radio Wide Scan option switch as
follows. If this switch is not programmed, radio wide
scanning is not available.
•To turn radio wide scanning on, press the Radio
Wide Scan option switch. Scanning is enabled when
“Scan” is indicated in the upper right corner of the
front panel display and “S AN ON” is briefly
displayed.
•To turn radio wide scanning off, press the Radio
Wide Scan option switch again. The “Scan” icon is
then no longer indicated and “S AN OFF” is briefly
displayed.

OPERATION
2-9 September 2001
Part No. 001-5100-001
•If the zone or channel is changed while radio wide
scanning, scanning continues normally.
2.5.4 SCAN RESUME DELAY
When a message is received or transmitted while
scanning, there is a system operator programmable
delay before scanning resumes. The delay after
receiving a call prevents another message from being
received before you can make a response, and the
delay after transmitting a call ensures that you hear a
response to your call instead of another message
occurring on some other channel.
2.5.5 STANDARD MODE SCAN LIST
NOTE: The selected channel is always scanned.
With conventional operation, up to three scan lists
can be programmed. The list that is scanned is selected
by the Scan option switch as described in Section
2.6.12. Selecting another conventional channel does
not change the current scan list. The scan lists are user
programmable if the Scan Edit option switch is
programmed (see Section 2.5.9).
With SMARTNET/SmartZone operation, each
channel can be programmed so that one of up to three
different scan lists is automatically selected or scan-
ning is disabled. The scan list assigned to the current
channel is not user selectable, but it is user program-
mable if the Scan Edit option switch is programmed
(see Section 2.5.9).
2.5.6 RADIO WIDE MODE SCAN LIST
With radio wide scanning, there is only one
preprogrammed scan list available regardless of the
type of channel selected, and it is not user
programmable.
2.5.7 DETERMINING WHICH CHANNELS ARE
IN SCAN LIST
hannels in the standard SMARTNET/Smart-
Zone and radio wide lists are not indicated. With
conventional channels, the selected channel is in the
current scan list if “SL” (Scan List) is indicated in the
upper part of the display.
2.5.8 NUISANCE CHANNEL DELETE
With standard scanning, channels can be tempo-
rarily deleted from the scan list, for example, if
messages on a channel become annoying. This feature
is not available with radio wide scanning. Proceed as
follows:
NOTE: The selected channel and conventional priority
channels cannot be deleted from the scan list.
1. While receiving a message on the channel to be
deleted, press and hold the Scan option switch until
the alert tone sounds (about 1 second).
2. The channel is then deleted and scanning of the
remaining channels in the scan list resumes.
3. Deleted channels are added back into the scan list if
any of the
following events occur:
•Scanning is turned off and then on again using the
Scan switch.
•Transceiver power is turned off and then on again.
•The scan list is reselected by pressing the number
key corresponding to the list number (conven-
tional) or by selecting another channel
(SMARTNET/SmartZone).
•Another channel is selected by the top panel
channel switch.
2.5.9 PROGRAMMING A SCAN LIST
When full keypad (18-key) models, conventional
and SMARTNET/SmartZone standard scan lists are
user programmable if the Scan Edit option switch is
programmed and user programming of the list is
allowed. Scan list programming is not available with
limited keypad (6-key) models. Proceed as follows to
program a scan list:
Preliminary
1. With conventional channels, select the list to be
edited (1-3) by pressing the key corresponding to
the desired list number with scanning enabled (see
Section 2.6.12). If a list is not selected, the last
active scan list is automatically edited. With
SMARTNET/SmartZone channels, the scan list for
