•“ASCEND” label on top edge of front panel
•Black front panel bezel
1.2 TRANSCEIVER DESCRIPTION
1.2.1 GENERAL
The 5300 series mobile transceivers can operate
on various types of channels and with various signaling
protocols (see following information). Models are
availablefor operation in the followingbands.Repeater
talk-around is also available with all bands.
VHF 136-174 MHz (35-watt models)
146-174 MHz (100-watt models)
UHF 380-470 MHz (Federal users only)
403-470 MHz
800 MHz 806-870 MHz (see following)
Power Output
Power output is user switchable for low and high
levels in the following ranges:
VHF 10-50W standard version,
50-100W high-power version
UHF 7-15W low power version*
10-40W med power version*
800 MHz 10-35W
*Version A and B models are available in the 15W configu-
ration only, and Version C models are available in the 40W
configuration only (see Section 1.12 for Version A/B/C
information).
1.2.2 ANALOG/DIGITAL OPERATION
The 5300 transceivers use a digital signal
processor (DSP) to provide IF and audio filtering and
signal modulation functions. This allows operation on
the following types of channels, backwards compati-
bility with existing equipment, and also the ability to
operate on various types of radio systems.
Narrow Band Analog - FM modulation is used with a
maximum deviation of 2.5 kHz. This mode is usually
used in systems with a channel spacing of 12.5 or
15 kHz.
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 5300 transceivers can be programmed for all
the following operating protocols. The conventional
analog protocol is standard and the others are optional
(available only if enabled by factory programming).
Refer to Section 3 for more operation information.
•APCO Project 25 (digital) conventional
•APCO Project 25 (digital) trunked

GENERAL INFORMATION
1-2
•SMARTNET®/SmartZone®trunked analog or
digital
•Analog conventional
NOTE: Multi-Net operation can be programmed with
Ascend models only.
1.2.4 AVAILABLE MOUNTING OPTIONS
Front Mount - The operating controls are on the front
on the radio, so the radio must be mounted within
reach of the user.
Remote Mount, Single Control Unit - The operating
controls are located on a remote mounted control unit.
The radio does not have operating controls.
Remote Mount, Dual Controls - A remote control
unit is connected to the front mount radio. This allows
control from the front panel and the remote control
unit.
Remote Mount, Dual Remote Control Units - Two
remote control units are connected to the remote
mount radio. This allows control from both remote
control units.
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 is a collection of channels or talk
groups belonging to the same repeater site. It defines
all the parameters and protocol information required to
access a site. Up to 16 systems of any type can be
programmed. The maximum number of channels
assignable to a system is limited to approximately 256
(or the available memory space as described in the
following information).
Channels
A channel selects a radio channel or talk group in
a system as follows:
Conventional Analog Mode - A channel selects a
specific radio channel, Call Guard (CTCSS/DCS)
squelch coding, and other parameters unique to that
channel.
Conventional Project 25 Mode - A channel selects a
specific radio channel, NAC squelch coding, talk
group ID, and other parameters unique to that channel.
Trunked Project 25 Mode - A channel selects a
specific talk group ID and other parameters unique to
that talk group.
SmartNet/SmartZone and Project 25 Trunked
Operation - A channel selects a specific talk group,
announcement group, emergency group, and other
parameters unique to that talk group.
As previously described, a maximum of up to 256
channels can be programmed. Although it is theoreti-
cally possible to program any combination of systems
that produces up to 256 total channels, 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 4 for more information.
Zones
A zone is a collection of up to 16 channels of any
type. For example, a zone could include 12 conven-
tional channels and 4 SMARTNET channels. 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 PROGRAMMING
Transceiver programming is performed using a
PC-compatible computer and an EFJohnson RPI
(Remote Programming Interface) and PCConfigure
programming software (see Table 1-1). Programming
is described in a separate included manual. Refer to
Section 4 for more information.
1.2.7 ALIGNMENT
Transceiver alignment is performed using the
same computer and RPI used for programming (see

GENERAL INFORMATION
1-3
preceding section) and special PCTune™software. All
adjustments are made electronically using the software
(no manual adjustments are required). Alignment is
described in Section 6.

1.5 SERIAL NUMBER BREAKDOWN
The radio serial number is located on the radio
identification label attached to the bottom cover (see
Figure 1-1). The following is a breakdown of this
number:
1.6 ACCESSORIES
The accessories available for this transceiver are
listed in Table 1-1. A brief description of some of
these accessories follows:
Key Cap Kit - The key cap kit includes key caps
labeled for various functions and five plugs that can be
inserted in the front panel if a key is not used. Refer to
Section 2.8 for more information.
Mounting Hardware - The mounting hardware and
DC power cable for standard models are shown in
Figures 2-1 and 2-3 in Section 2. The mounting hard-
ware and DC power cable for 100-watt models are
shown in Figure 2-4. A 22-foot DC power cable is
used for both front and remote mount applications.
The cable is cut to the required length at installation
and any excess discarded.
The accessory cable plugs into the accessory
pigtail of the transceiver, and is used to connect such
things as an external speaker, ignition sense input, and
a horn alert. It includes two 22-foot and three 2-foot
wires that are connected as required to external points.
The adapter cable is used to connect a 86xx-series
power cable to these transceivers.
Lockable Mounting Tray - This bracket allows the
transceiver to be locked in place to guard against theft.
In addition, it allows it to be easily unlocked and
removed from the vehicle. This bracket is intended for
use with standard models only (not 100W). Refer to
Section 2.10 for installation information.
Microphones and Speaker - The microphones in
Table 1-1 have an impedance of 620 ohms. All DTMF
microphones are backlighted. The environmentally
sealed microphone is sealed against such things as
rain, sand, and dust. The desk microphone can be used
for control station applications.
The external 15-watt speaker can be used in place
of the internal 5-watt speaker. It is non-amplified and
weatherproof. This speaker is connected to pins 1 and
2 of the accessory connector pigtail on the back of the
transceiver. Audio power output is 12 watts with this
external speaker or 5 watts with the internal speaker.
Control Station Power Supply - With the -4001-
medium-duty power supplies, the transceiver slides
into the power supply housing and receives power
from banana jacks on the back of the power supply.
The standard power cable is used for connecting
power, and the internal transceiver speaker provides
speaker audio. The -004 adapter cable is used to
connect the transceiver DC and accessory pigtail
cables to the power supply power cable and speaker.
The transceiver internal speaker can also be used if
desired.
Programming Hardware and Software - The RPI
provides the interface between the programming
computer and transceiver. The cables from the RPI to
computer and transceiver are not included with the
RPI and must be ordered separately. The transceiver
programming software is available only for computers
running Windows®95/98/NT/2000/XP.
