December 2008 5300 ES Series Mobile Radio Service Manual 1-2General Information1.1.1 Analog / Digital OperationThe 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 ProtocolsThe 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 conventionalNote Multi-Net operation can be programmed with Ascend models only.1.1.3 Available Mounting OptionsFront 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.

December 2008 5300 ES Series Mobile Radio Service Manual 1-3General Information1.1.4 Systems, Channels, and ZonesA zone and channel are selected to place and receive calls. The following describes the relationship between systems, channels, and zones.1.1.4.1 SystemsA 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 ChannelsA 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 ZonesA 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.

December 2008 5300 ES Series Mobile Radio Service Manual 1-8General Information1.5.1 FIPS 140-2 Approved EncryptionAll 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 RetentionNote 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.

December 2008 5300 ES Series Mobile Radio Service Manual 5-1SECTION5Section 5Troubleshooting5.1 User TroubleshootingWhen 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 DischargeIn 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.

December 2008 5300 ES Series Mobile Radio Service Manual 5-2Troubleshooting5.3 5300 Viewing AngleIf 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 TroubleshootingIf 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 TroubleshootingIf 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 InformationPlease refer to the 5300 ES Series Mobile Installation Manual for installation instructions and information (Part Number 004-5300-011).
