1.1 Radio Description

The 5300 ES Series mobile radios can operate on various types of channels and with
various signaling protocols. Repeater talk-around is also available.

December 2008 5300 ES Series Mobile Radio Service Manual 1-1

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, backwar ds compatibil ity with exis ting equip ment, 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

• Analog conventional

Note Multi-Net operation can be programmed with Ascend models only.

®

/SmartZone® trunked analog or digital

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 allow s control from both remot e control units.

December 2008 5300 ES Series Mobile Radio Service Manual 1-2

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 b e pr ogr amme d. Th e maxi mum number of cha nnel s a ss ignable 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 syste m s i ncr ea ses. The
programming software disp lays a bar g raph whi ch sho ws th e amount of av aila ble memor y
space that i s used by the current data.

1.1.4.3 Zones

A zone is a collect ion of up to 16 channels of any type. For example, a zone coul d i ncl ude
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.

algorithm. The following types of encryption are available on analog and digital channels:

Analog Conventional and SMARTNET/SmartZone Analog Channels

-DES
Digital Project 25 and SMARTNET/SmartZone Channels

- DES-OFB (Output Feedback)

- AES (Advanced Encryption Standard). Refer to Section 11 of the Operating Manual
for your radio for more information.

December 2008 5300 ES Series Mobile Radio Service Manual 1-7

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 loa ded int o the ra dio by OTAR (O ver-the -Air- Rekeying ) using a Key
Management Facility (KMF) and/or a handheld keyloader such as the EFJohnson
Technologies Subscribe r Management Assist ant (SMA) or Mot orola 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 use d to load DES-OFB keys on
Project 25 conventional channels. Refer to Section 10 of the Operating Manual for your
radio for mor e 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 K ey Retention Infinite Ke y Retention i s 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-v olt supply ( and the
encryption keys) for approximately eight hours if power is temporarily lost.

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.

S ECTION

5

Section5Troubleshooting

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 trans ceiver.

• 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 transcei ver should b e turned off when not in use . Since power consumpt ion 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.

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.

Troubleshooting

If the transc eiver 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.

If UNPROGRAMD” is displayed, the cause could be any of the following:

• An unprogrammed channel is selected. Select a programmed channel.

programming was detected. The radio needs to be reprogrammed.
