![](/img.php?id=1067228&img=bge.png)
December 2008 5300 ES Series Mobile Radio Service Manual 1-2
General Information
1.1.1 Analog / Digital Operation
The 5300 ES Series mobile radios 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 compatibility 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 standard. This mode uses a channel spacing of 12.5 kHz.
1.1.2 Operating Protocols
The 5300 ES Series mobile radio 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).
• APCO Project 25 (digital) conventional
• APCO Project 25 (digital) trunked
• SMARTNET®/SmartZone® trunked analog or digital
• Analog conventional
Note Multi-Net operation can be programmed with Ascend models only.
1.1.3 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.

General Information
1.1.4 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.
1.1.4.1 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 is
limited to 864 based on the option enabled. Channels may also be limited by available
memory space as described in the following information.
1.1.4.2 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.
A maximum of up to 864 channels can be programmed. Although it is theoretically
possible to program any combination of systems that produces up to 864 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.
1.1.4.3 Zones
A zone is a collection of up to 16 channels of any type. For example, a zone could include
12 conventional 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 54 zones
can be programmed depending on the option enabled.

General Information
1.5.1 FIPS 140-2 Approved Encryption
All encrypted 5300 ES Series mobile radio models are FIPS certified for the DES-OFB
and AES encryption modes. Encryption on analog channels is not FIPS certified. FIPS
140-02 is a Federal Information Processing Standard recently approved by the United
States Secretary of Commerce. This standard specifies Federal security requirements for
cryptographic modules for a wide range of applications and environments.
1.5.2 Over-the-Air-Rekeying (OTAR)
Encryption keys are loaded into the radio by OTAR (Over-the-Air-Rekeying) using a Key
Management Facility (KMF) and/or a handheld keyloader such as the EFJohnson
Technologies Subscriber Management Assistant (SMA) or Motorola KVL 3000 Plus with
the AES option.
The keyloader is connected directly to the radio using an interconnect cable, and it loads
DES, DES-OFB, and AES keys. Currently, OTAR can be used to load DES-OFB keys on
Project 25 conventional channels. Refer to Section 10 of the Operating Manual for your
radio for more OTAR information.
1.5.3 Key Retention
Note The 5300 ES Series mobile radio has a security feature (push-button switch S1 on the
logic board) that automatically erases the encryption keys when the bottom cover is
removed (except when Infinite Key Retention is programmed as follows).
If Infinite Key Retention Infinite Key Retention is programmed, the keys are maintained
in memory indefinitely, even without power applied. If it is not programmed, the radio
must be connected to an unswitched power source to preserve the encryption keys in
memory. However, a storage capacitor (C173, 0.22 F) maintains the 5-volt supply (and the
encryption keys) for approximately eight hours if power is temporarily lost.

Section 5Troubleshooting
5.1 User Troubleshooting
When approaching the limits of radio range, the other party may not be able to hear your
transmissions and there may be an increase in background noise when messages are
received.
You may still be out of range even though you can hear a message.
• The reason for this is that the signal you are receiving is usually transmitted at a higher
power level than the one transmitted by your transceiver.
• Communication may be improved by moving to higher ground or away from shielding
objects such as tall buildings or hills.
5.2 5300 Battery Discharge
In the standby mode (power on, not transmitting), transceiver power consumption is
relatively low. Therefore, you can probably leave the transceiver on for one or two days
without operating the vehicle and the battery should not become seriously discharged.
However, if the outdoor temperature is low enough to significantly decrease battery
capacity, the transceiver should be turned off when not in use. Since power consumption is
significantly higher when transmitting, it is good practice to have the vehicle running
while transmitting. This ensures that optimum power is being delivered to the transceiver
and that the battery does not become discharged.

Troubleshooting
5.3 5300 Viewing Angle
If no characters or all characters appear in the display, the viewing angle may be
improperly adjusted. If the display is difficult to read from the angle you normally view it,
the viewing angle can be adjusted as follows: Press and hold the last option switch above
the display and then press the first option switch above the display. Release both switches
and turn the Select switch until the best contrast is obtained. This function times out in
three to five seconds.
5.4 5300 User Troubleshooting
If some other problem is occurring, turn power off and then on again to reset the control
logic. Also make sure that the controls are properly set and that the power, external
speaker, and accessory cables (if used) are securely plugged into the back of the
transceiver.
If the transceiver is completely inoperative, check the power cable fuse that is usually
located near the vehicle battery. If it is blown, remedy the cause if possible and replace it
with the same type (15A). If the transceiver still does not operate properly, return it to your
system operator for service.
5.5 User Troubleshooting
If UNPROGRAMD” is displayed, the cause could be any of the following:
• An unprogrammed channel is selected. Select a programmed channel.
• The selected channel is programmed for an option that is not installed or an error in
programming was detected. The radio needs to be reprogrammed.
5.6 Additional Information

6.5 Returns for Repairs
Before returning equipment for repair, contact the EFJohnson Technologies Customer
Service Department as described in the preceding section. They may be able to suggest a
solution to the problem, making return of the equipment unnecessary.

returned to the EFJohnson Technologies repair depot for repair. However, before
returning equipment, contact the Customer Service Department Repair Depot for the
correct Ship To” address.

whether it is in or out of warranty. You can obtain it in any of three ways:
• Download it from the EFJohnson Technologies Web site’s Service & Support” section.
• Call the EFJohnson Technologies Customer Service Department and request it. See

physical damage to the equipment. Include this form in the shipping container with each
unit. Your telephone number and contact name are important as there are times when the
technicians may have specific questions that need to be answered to completely identify
and repair a problem.
When returning equipment for repair, it is also recommended that you use a PO number or
some other reference number on your paperwork in case you need to call the repair lab
about your unit. These numbers are referenced on the repair order and make it easier and
faster to locate your unit in the lab.
Return Authorization (RA) numbers are not necessary unless you have been given one by
the Field Service Department. RA numbers are required for exchange units or if the Field

RA number, reference this number on the Factory Repair Request Form sent with the unit.
The repair lab will then contact the Field Service Department when the unit arrives. For
