1-1September 2001Part No. 001-5100-001GENERAL INFORMATIONSECTION 1 GENERAL INFORMATION1.1 SCOPE OF MANUALThis service manual contains alignment and service information for the E.F. Johnson 5100-Series portable digital transceivers.1.2 TRANSCEIVER DESCRIPTION1.2.1 GENERALThe 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 switchable for low and high levels as follows: 800 MHz - 3 watts only1.2.2 ANALOG/DIGITAL OPERATIONThe 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 PROTOCOLSThe 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 MODELSBoth 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, and keypad programming. The other keys (*, #, and F1-F4) have dual functions. They can be assigned a function using the programming software and are also used to navigate through menus. The 6-key models have keys below the display which are programmable function keys, and also keys that are used for menu navigation.1.2.5 SYSTEMS, CHANNELS, AND ZONESA zone and channel are selected to place and receive calls. The following describes the relationship between systems, channels, and zones.SystemsA 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 INFORMATION1-2 September 2001Part No. 001-5100-001ChannelsA 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, 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. ZonesA 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 COMMUNICATIONSecure communication is available with all the preceding protocols.

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 VOLUMEPower 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 GeneralThe 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 “LOCKED” 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, “LOCKED” is again displayed. Changing PasswordThe 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 “LOCKED”.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.

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 Calls 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 LOCKIf 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 INDICATIONWhen 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 SELECTIONChannel SelectTo 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 SelectA 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.
OPERATION2-7 September 2001Part No. 001-5100-0012.4.9 HOME ZONEThe 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 TIMERThe 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. Conventional channels can also be programmed with the Penalty and Conversa-tion timers that are described in Sections 2.6.7 and 2.6.8.2.4.11 TONE ENABLE/DISABLEThe 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. Conversely, 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 MODESIntroductionEach selectable channel can be programmed for either the conventional or SMARTNET/SmartZone operating mode. For example, Zone 1/Channel 1 could be a conventional channel, Zone 1/Channel 2 a SMARTNET channel, and so on. More information on these modes follows.Conventional ModeThis 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. Channel monitoring and other operating features unique to conventional channels are described starting with Section 2.6.1.SMARTNET™/SmartZone® ModeThis 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, Call 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.
OPERATION2-8 September 2001Part No. 001-5100-001The 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 Clear/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 SCANNING2.5.1 INTRODUCTIONScanning 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 SCANNINGStandard 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 “SCAN ON” is briefly displayed. •To turn scanning off, press the Scan option switch again. The “Scan” icon is then no longer indicated and “SCAN 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 SCANNINGRadio 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 “SCAN 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 “SCAN OFF” is briefly displayed.
OPERATION2-9 September 2001Part No. 001-5100-001•If the zone or channel is changed while radio wide scanning, scanning continues normally.2.5.4 SCAN RESUME DELAYWhen 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 LISTNOTE: 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 LISTWith 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 LISTChannels 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 DELETEWith 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 LISTWhen 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:Preliminary1. 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
OPERATION2-10 September 2001Part No. 001-5100-001the selected channel is fixed and cannot be changed. Scanning may also be disabled on some channels.2. If scanning is enabled, turn it off by pressing the Scan option switch. 3. Press the Scan Edit option switch. The alias of the first channel in the scan list is displayed. If scan list programming or scanning is disabled on the selected list or channel, “NO LIST” is momentarily displayed and scan list programming is not avail-able. Proceed as follows to delete or add a channel:To Delete a Channel:4. Select the channel you want to delete by pressing the and keys. 5. With conventional channels, to delete the displayed channel and exit this mode, press the CLR (F3) key. With SMARTNET/SmartZone channels, press the “2” key and then ENT (F4). NOTE: The priority channel cannot be deleted (see Section 2.6.13).To Add a Channel:1. Press the Scan Edit option switch. The alias of the first channel in the scan list is displayed.2. Enter the two-digit zone and channel number of the channel you want to add. For example, to add Zone 1/Channel 5, enter “0105”. Refer to Section 2.4.8 for more information on zones and channels.3. With conventional channels, to add the channel to the scan list and exit this mode, press the ENT (F4). With SMARTNET/SmartZone channels, press the “1” key and then ENT (F4).2.6 CONVENTIONAL FEATURES2.6.1 INTRODUCTIONThe following information describes features unique to the conventional operating mode (see brief description in Section 2.4.12). Refer to Section 2.4 for information on features common to all operating modes, and to Section 2.7 for information on features unique to the SMARTNET/SmartZone mode.2.6.2 DISPLAY MODE SELECTIONIf the Displayed Information option switch is programmed, it is usually the three-position toggle switch on the top panel. This switch selects the following conventional channel display modes. If this switch is not programmed or a SMARTNET/Smart-Zone channel is selected, the Alias mode is always used. Alias - The preprogrammed alphanumeric tag for the channel is displayed. Number - The channel number from 1-16 is displayed as “CHAN xx”. Frequency - The frequency of the selected channel is displayed in megahertz. The transmit frequency is displayed in the transmit mode and the receive frequency is displayed in the receive mode.NOTE: The channel number can also be determined by noting the number (1-16) indicated by the index on the channel selector knob.2.6.3 MONITORING BEFORE TRANSMITTINGWith conventional operation, you may need to manually monitor the channel before transmitting to make sure that it is not being used by someone else. If you were to transmit while someone else was using the channel, you would probably disrupt their conversa-tion. Channels are monitored automatically or manu-ally as follows:Automatic Channel MonitoringIf the selected channel is programmed for Busy Channel Lockout feature (consult your system oper-ator), monitoring is performed automatically. Refer to the description of this feature in Section 2.6.5 for moreinformation.Manual Channel MonitoringThe automatic monitoring just described may not be programmed or it may occasionally disable the
OPERATION2-11 September 2001Part No. 001-5100-001transmitter even if the channel is not in use. In this case, the channel must be monitored manually as follows:Rx Indicator - With scanning disabled, note if the indi-cator on the top panel is steady green. If it is not, the channel is not being used and you can transmit your call. If it is green, the channel may be busy and you should not place your call (see next paragraph). Monitor Mode - There may be times when the busy indication is displayed even though no one is using the channel. Monitoring should then be performed by disabling Call Guard squelch using the Normal/Selec-tive option switch as described in Section 2.6.6 or the monitor mode described next.2.6.4 MONITOR MODEThe monitor mode temporarily disables squelch control features (such as Call Guard® squelch) so that all messages are heard on the selected channel. It also overrides the Busy Channel Lockout feature (see next section) and temporarily halts scanning.To monitor the selected channel, select the monitor mode by briefly pressing or pressing and holding the Monitor option switch (if available). The receiver unsquelches and a rushing noise or voice is heard when the monitor mode is enabled. To disable the monitor mode and return to normal operation, release the Monitor switch or press it a second time.If scanning is enabled, pressing and holding the Monitor option switch monitors the current scanned channel instead of the selected channel if applicable. 2.6.5 BUSY CHANNEL LOCKOUTThe Busy Channel Lockout feature (also called Transmit Disable On Busy) automatically disables the transmitter if the channel is busy when the PTT switch is pressed. When a busy condition is detected by this feature, the transmitter is disabled, “BUSY” is indi-cated in the display, and a tone similar to a standard telephone busy tone sounds until the PTT switch is released. The transceiver can be programmed to operate in one of the following modes on each channel: Off - Busy channel lockout is disabled and the trans-mitter keys even if the channel is busy.Noise - The transmitter is disabled if a carrier is detected on the channel.Tone - The transmitter is disabled if an incorrect Call Guard (CTCSS/DCS) or NAC code is detected (see Section 2.6.6). An incorrect code is any code other than the one programmed for the current channel.If busy override is permitted by programming, it is possible to transmit even when the transmitter is disabled by this feature. Simply release the PTT switch and then quickly press it again.2.6.6 CALL GUARD SQUELCHIntroductionTone or digital Call Guard squelch (also called CTCSS/DCS signaling) can be programmed on each conventional analog transmit and receive channel in any order desired. The reverse burst and turn-off code are always transmitted and also detected on channels programmed with Call Guard squelch. The Call Guard squelch feature eliminates distracting messages intended for others using the channel. This is done by using a subaudible tone or digital code to control the squelch. This tone or code is unique to a user or a group on that channel. This tone or code is transmitted with the voice signal but is not heard because it is in the subaudible range and is atten-uated by a filter. Call Guard squelch must be used in both the transmitting and receiving transceiver to be functional. Call Guard Squelch Enable/DisableTo disable Call Guard (Selective) squelch so that all messages on the selected or scanned channels are heard, press the Normal/Selective option switch (if available) so that “NORMAL is flashed in the display. Then to re-enable Call Guard squelch, press the Normal/Selective switch again so that “SELECTIV” is flashed. The mode selected by this switch does not change when other channels are selected or power is cycled. Call Guard squelch can also be disabled by the monitor mode described in Section 2.6.4.
OPERATION2-12 September 2001Part No. 001-5100-001Tone Call Guard Squelch Tone-type Call Guard squelch utilizes subaudible CTCSS tones from 67-254.1 Hz. Although there are 42 tones assigned, those above 33 (210.7 Hz) are normally not used because of their close proximity to the voice band which starts at 300 Hz. In addition, tones 11 (97.4 Hz), 39 (69.3 Hz), 40 (206.5 Hz), 41 229.1 Hz), and 42 (254.1 Hz) are normally not used because they may cause interference with adjacent tones.A reverse burst is transmitted when the push-to-talk switch is released and also detected when calls are received. It is a 180-degree phase reversal for a period of time determined by the tone frequency, and it elimi-nates the squelch tail (noise burst) in the receiving transceiver. Both the transmitting and receiving trans-ceiver must be equipped with this feature for it to be utilized. Digital Call Guard Squelch Digital Call Guard squelch (CDCSS) uses digital data instead of subaudible tones to control the squelch. This data consists of continuous repetitions of 23-bit words. No bit or word synchronization information is used. When the push-to-talk switch is released, a turn-off code is transmitted which eliminates the squelch tail similar to the reverse burst. Although there are thousands of possible code combinations with 23 bits, only 83 are unique with the data scheme used. The number specified when the code is programmed is actually a seed for a special algorithm used to generate the 23-bit data word. The data is transmitted at a rate of 134.4 bits per second. Therefore, approximately six words are transmitted each second. When the data is decoded, 23-bit samples are taken and then the bits are rotated to determine if a valid code was received.Keypad Selectable Call Guard Code (CTCSS/DCS)If you have the full keypad (18-key) model and the ability to change Call Guard codes has been enabled by programming, the transmit and receive codes from one channel can be temporarily or perma-nently reassigned to all channels of the current zone. Proceed as follows:1. Using the number keys, enter the number of the channel that is programmed with the code you want to reassign to all channels (only channels 1-9 can be selected). See Section 2.6.2 for information on displaying channel numbers.2. The display then briefly indicates “CODE x”, where “x” is the key you pressed. The codes assigned to that channel are then reassigned to all the other channels in the current zone. The reassignments remain in effect even after power is cycled.3. To restore all Call Guard codes in the current zone to the original settings, press the “0” key. NOTE: Keypad programming described in Section 2.9 can be used to change the Call Guard code of indi-vidual channels.2.6.7 PENALTY TIMERA penalty timer may be programmed on conven-tional channels to prevent transmissions for 15 - 225 seconds after the time-out timer described in Section 2.4.10 disables the transmitter. The penalty timer starts when the PTT switch is released after the transmitter has been disabled. If the PTT switch is pressed during the penalty time, the time-out indication occurs again. A beep sounds when the penalty timer expires and the transmitter can then be keyed.2.6.8 CONVERSATION TIMERA conversation timer can be programmed on conventional channels to limit the total length of a conversation rather than just the length of each trans-mission as with the time-out timer. This timer can be programmed for 0.5 - 7.5 minutes, and it is reset when the time between transmissions exceeds the penalty time just described. A warning tone sounds 5 seconds before the conversation timer expires. When it expires, the transmitter is disabled and a warning tone sounds. The transmitter remains disabled for the length of the penalty time, and a beep sounds when it can be keyed again.2.6.9 REPEATER TALK-AROUNDNormally, all your transmissions go through a repeater which usually increases range. However, if
OPERATION2-13 September 2001Part No. 001-5100-001you are out of range of the repeater, you cannot talk to anyone else on that channel even though the mobile you are calling may be only a short distance away. To allow communication when this situation occurs, repeater talk-around can be used to allow direct communication with a mobile without going through a repeater.Repeater talk-around can be selected if the Repeater Talk-Around option switch (if available). When talk-around is enabled by this switch, “RTA ON” is flashed in the display. Then when it is disabled by pressing the switch again, “RTA OFF” is flashed. Changing channels or turning power off does not change the selected talk-around mode.2.6.10 POWER OUTPUT SELECTIf the High/Low Power option switch is programmed and power selection is permitted on the current channel, either high or low transmitter power can be selected. Generally, the high power setting allows you to transmit longer distances but uses more battery power, and the opposite occurs with the low power setting. Pressing the High/Low Power switch toggles the power setting. The new level is flashed in the display when this switch is pressed as “HI POWER” or “LO POWER”. If power selection is not permitted on the channel, the fixed power level is flashed and no power change occurs. Turning power off or changing chan-nels does not change the power setting selected for a channel. Selectable power is not available with 800 MHz models.2.6.11 EMERGENCY MODE (CONVENTIONAL)On conventional channels, an emergency mode may be programmed to be selectable by the Emer-gency switch located next to the antenna (see illustra-tion in Section 2.3.2). Scanning is automatically disabled in the emergency mode, so transmissions occur on the selected channel. If an analog channel is selected and scrambling is programmed, pressing the Emergency switch sends an emergency signal on the selected channel 20 times or until an acknowledgment is received. Keying the radio also cancels the emergency condition.If a Project 25 (digital) channel is selected, pressing this switch selects the emergency mode and if the PTT switch is pressed, an emergency status is sent. Radio power must be turned off to cancel the emer-gency mode on a Project 25 channel.2.6.12 CONVENTIONAL MODE SCANNINGGeneralThe following information describes scanning features unique to conventional operation. Scan opera-tion common to all modes is described in Section 2.5, and scan operation unique to SMARTNET/SmartZone operation is described in Section 2.7.12.Selecting a Scan ListWith full keypad (18-key) models, one of up to three scan lists can be selected when scanning with a conventional channel selected. These lists can be system operator or user programmed as described in the information which follows. With limited keypad (6-key) models, only one scan list is available and it cannot be user programmed. However, nuisance chan-nels can still be temporarily deleted as described on Section 2.5.8. Proceed as follows to select a scan list with full keypad models: 1. If required, enable scanning by pressing the Scan option switch. 2. To select a list, press the number key corresponding to the number of the desired list (1-3). The selected list is then briefly displayed as “Scan x” where “x” is the list number. The selected scan list is stored in memory and does not change until this procedure is repeated.Transmitting in Scan ModeEach conventional scan list can be programmed for one of the following modes. These modes deter-mine if priority sampling occurs and also the channel on which transmissions occur while scanning. Refer to the next section for more information.
OPERATION2-14 September 2001Part No. 001-5100-001No Priority - No priority channel sampling occurs when the list is selected. The radio transmits on the selected channel.Priority/Tx Priority - Priority sampling occurs and the priority channel is the one programmed in the selected scan list. The radio transmits on the priority channel.Priority/Tx Selected - Priority sampling occurs and the priority channel is the one programmed in the selected scan list. The radio transmits on the selected channel.Priority on Selected - The priority channel is always the selected channel. The radio transmits on the selected channel. Talk ba c k - No priority sampling occurs. The radio transmits on the channel of a call while scanning is halted. Then once scanning resumes, it transmits on the selected channel.2.6.13 PRIORITY CHANNEL SAMPLINGGeneralThe priority channel sampling feature ensures that when standard scanning is occurring, messages on the priority channel are not missed while listening to a message on some other channel. Your transceiver can be programmed so that the priority channel is a fixed channel associated with the current scan list, the currently selected channel, or not used. When the selected channel is a priority channel, “Pri” is indi-cated in the upper part of the display.Priority channel sampling occurs only with Stan-dard conventional scanning. It does not occur with Radio Wide scanning, when listening to any type of SMARTNET/SmartZone call, or when transmitting. A series of “ticks” may be heard and the indicator on the top panel flashes green when the priority channel is sampled while listening to a message on some other channel. The priority sampling times are programmed by the following parameters:Lookback Time A - This time determines how often the priority channel is checked for activity. Times of 0.25-4.00 seconds in 0.25-second steps can be programmed.Lookback Time B - This time determines how often the priority channel is checked once an incorrect Call Guard (CTCSS/DCS) or NAC code is detected. Since it takes much longer to detect an incorrect Call Guard signal than a carrier, this time should be relatively long to prevent the interruptions from making a message difficult to understand. Times of 0.5-8.0 seconds can be programmed in 0.5-second steps.Changing The Priority ChannelIf a specific priority channel is associated with the current scan list, it can be changed if the Priority option switch is programmed. Proceed as follows:1. Select the scan list number to be edited as described in Section 2.6.12. If a list is not selected, the last active scan list is automatically edited.1. Make sure that both radio-wide and standard scan-ning are off (“Scan” is not indicated in display). 2. Select the channel that you want to be the priority channel using the channel selector switch on the top panel. If the channel is in a different zone, also select the appropriate zone.3. Press the Priority option switch and the “Pri” is displayed to indicate that the selected channel is now the priority channel.2.6.14 PLACING AND RECEIVING STANDARD CONVENTIONAL CALLSStandard conventional calls are calls to or from other mobile units on the selected channel. The proper coded Call Guard signaling (see Section 2.6.6) may need to be transmitted for them to receive your call and also for you to receive their calls. Proceed as follows to place and receive these calls:Placing a Standard Conventional Call1. Turn power on and set the volume as described in Section 2.4.2. Select the channel programmed for the mobile you want to call (see Section 2.4.8).
OPERATION2-15 September 2001Part No. 001-5100-0012. Monitor the channel automatically or manually as described in Section 2.6.3.3. Press the PTT switch and the call proceeds as follows:•If the Busy Channel Lockout feature is programmed on the channel, the transmitter is automatically disabled if the channel is busy (see Section 2.6.5). •Otherwise, busy and out-of-range conditions are not indicated and speaking can begin after monitoring the channel as described in Section 2.6.3. 4. Press (and hold) the PTT switch to talk and release it to listen.Receiving a Standard Conventional Call1. Select or scan the channel programmed for the call you want to receive (refer to Sections 2.5 and 2.6.12 for more scanning information).2. When the call is received, press the PTT switch to talk and release it to listen. If scanning, you may have to respond before scanning resumes to ensure that the response occurs on the channel of the call. 2.6.15 DTMF/ANI SIGNALINGDTMF (Dual Tone Multi-Frequency) tones can be generated manually or automatically for ANI (Automatic Number Identification) and other purposes. The following options may be enabled by system operator programming for each conventional channel:DTMF Keypad - Pressing 0-9, *, or # on the keypad while holding the PTT switch transmits the corre-sponding tone until the key is released.Pre-Tx ANI - A preprogrammed ANI sequence is automatically sent when you press the PTT switch.Post-TX ANI - A preprogrammed ANI sequence is automatically sent each time you release the PTT switch. Disabled - All DTMF signaling is disabled.2.6.16 PROJECT 25 MODE FEATURESIndividual, Group, and NAC CodesIndividual ID - Each transceiver that operates on Project 25 (digital) channels is programmed with an 8-digit individual ID. This ID is unique for each transceiver and can be any number from 1-16777216. When power is turned on with a Project 25 channel selected, this ID is briefly displayed.Group ID - Each Project 25 channel is programmed with a group ID that determines which group of mobiles will receive the call. A call is received if any Project 25 channel is programmed with that group and the correct NAC is detected (see following description). Group IDs can be any number from 0-4095.NAC - Project 25 conventional channels use a NAC (Network Access Code) instead of Call Guard squelch coding (see Section 2.6.6) to control which calls are received on a channel. The NAC can be 0-4095, and each transmit and receive channel can be programmed for a different code. Other operation, such as monitoring before trans-mitting, is similar to that of standard analog channels.To receive a Project 25 group call, the talk group programmed with the group ID being transmitted must be selected or scanned. In addition, the receive NAC programmed for that channel must be detected.Viewing Individual IDEach transceiver which operates on Project 25 (digital) channels is assigned an eight-digit individual ID. When power is turned on with a Project 25 channel selected, the individual ID of your radio is briefly displayed.Changing Talk Group Assigned To A ChannelIf the Talk Group Select option switch is programmed and user talk group programming is permitted on the channel, the talk group assigned to a channel can be changed. This change is permanent
OPERATION2-16 September 2001Part No. 001-5100-001(cycling power does not reselect the old talk group). Proceed as follows:1. Select the channel to be changed and then press the Talk Group Select option switch.2. Display the talk group to be assigned to that channel by pressing the and keys. Talk groups are indicated by an alias (unique alphanumeric identifi-cation).3. To select that talk group and return to normal oper-ation, press the Talk Group select switch again. If talk group selection has been disabled on the chan-nel by programming, the talk group does not change and an error tone sounds.Individual CallsIf the Individual Call option switch is programmed and the radio is a full keypad (18-key) mode, individual calls can be placed to a specific mobile radio on Project 25 channels. This call differs from standard group calls in that only one mobile instead of entire groups of mobiles may receive the call. To respond to an individual call, simply press the PTT switch and begin talking before a call timer expires. Proceed as follows to place this call:1. Press the Individual Call option switch and the iden-tification of the last individual call placed is dis-played as IDxxxxxx.2. If required, enter the ID of the mobile being called using the keypad. 3. Press the PTT switch and begin talking. When individual calls are received, the trans-ceiver may be programmed to display the selected talk group, the talk group of the call, or the ID of the calling radio.2.6.17 CONVENTIONAL SECURE COMMUNICATIONIntroductionThere are two different protocols that can be used to provide secure communication on conventional analog channels: SecureNet™ and 460 scrambling. More information on these protocols follows.SecureNetSecureNet is a proprietary Motorola protocol that digitizes the voice and then encrypts it using the DES algorithm. It provides the highest level of security. There are two DES protocols:•DES (CFB) uses cipher feedback DES encryption. A disadvantage of this type is reduced communica-tion range when compared to clear voice.•DES-XL uses counter addressing feedback DES. It provides better range but at lower voice quality. The transmission mode (DES or DES-XL) is selected by the programming software for each SecureNet analog channel. If a channel is programmed for DES-XL, it will also receive DES, but transmis-sions always occur in DES-XL. Each SecureNet capable channel is assigned an encryption number from 0-15. The key corresponding to this number is loaded into the radio using the Motorola key loader. There is a maximum of 16 keys that can be loaded into the radio at one time.Transmissions on an analog channel are in the clear mode if the channel has been strapped to the clear mode by programming, and in the SecureNet mode if it has been strapped to SecureNet. If the channel has been strapped to “switched”, the mode is selected by the Clear/Secure option switch. When a message is received or transmitted in the secure mode, “Sec” is indicated in the upper part of the display.If an attempt is made to transmit a secure message without loading the corresponding key, “KEYFAIL” is displayed. The message must then be transmitted in the clear mode (this is possible only if the channel is strapped to “switchable”) or the key must be loaded.460 ScramblingThe 460 Scrambling protocol is a proprietary Transcrypt protocol that is compatible with the stand-alone scrambling option from Transcrypt. If equipped
OPERATION2-17 September 2001Part No. 001-5100-001with the 460 Scrambler, a Clear/Secure option switch may be programmed. Pressing this switch changes the transmission mode for the selected channel and momentarily displays either “CLEAR” or “SECURE”. In the coded mode, transmissions are in scram-bled voice on any 460-enabled channel and the mobile receiving the call automatically responds in the scram-bled mode because the receiver automatically switches between the clear and coded modes. Although 16 generic codes are loaded, only one is active and all 460-enabled channels use this code. The 460 scrambling option also provides several other signaling enhancements including Digital ID, Auto-matic Status and Location Update, Individual and Group ID calling, and Emergency. Transmit Mode OptionsEither the SecureNet or 460 protocol can be selected, and then the following transmit options are available for each:Clear - All calls are in the clear mode unless responding to a secure call. If the response is then made within the delay time (see Section 2.5.4), it occurs in the secure mode.Coded - All calls are made in the selected secure mode. Switched - The mode is selected by the Clear/Secure switch. With 460 scrambling, if responding to a secure call, the secure mode is automatically selected if the response occurs within the delay time. When the clear mode is selected by this switch, “CLEAR” is flashed, and when the secure mode is selected, “SECURE” is flashed.Receive Mode OptionsWith 460 scrambling, clear and scrambled signals are always autodetected. In addition, the user can switch between the clear and secure mode at any time using the Clear/Secure option switch. SecureNet signals are unintelligible when 460 scrambling is used and vice versa.With the SecureNet protocol, the following receive options can be programmed:No Autodetect - Only signals coded like the transmit signals are received.Secure Autodetect - Both clear and SecureNet signals are automatically detected. This mode is automati-cally selected if the transmit mode is switch selectable.Proper Key Autodetect - An incoming Securenet call is compared against all of the available keys programmed into the radio. If a match is found, the call is decrypted using matched key. Project 25 (Digital) ChannelsProject 25 digital channels use the DES-OFB protocol. Using this protocol on digital channels does not result in the degraded range that occurs with analog channels. The same transmit mode options are available as with the preceding analog operation. In the receive mode, clear and secure messages are always automatically detected.2.7 SMARTNET/SMARTZONE FEATURES2.7.1 INTRODUCTIONThe following information describes features unique to the SMARTNET and SmartZone operating mode (see brief description in Section ). Refer to Section 2.4 for information on features common to all operating modes, and to Section 2.4.12 for information on conventional mode features. 2.7.2 VIEWING UNIT IDEach radio in a SMARTNET system is identified with a six-digit system ID and Unit ID. To display these IDs, make sure that a SMARTNET channel is selected and then turn power off and then on again. The system ID is briefly displayed as SYxxxxxx followed by the Unit ID as EDxxxxxx. 2.7.3 STANDARD GROUP CALLSStandard group calls are between you and another mobile, group of mobiles, or a control station (a radio

Press the CLR key to return to normal operation.2.7.10 EMERGENCY ALARM AND EMERGENCY CALLEmergency alarms and emergency calls are sepa-rate functions that can be individually programmed on SMARTNET/SmartZone channels. The Emergency switch is pressed to initiate these features. This switch is the orange button located next to the antenna connector.An emergency alarm is a special data transmis-sion to alert your dispatcher of an emergency situation, and an emergency call is an urgent request for access to a voice channel. The emergency alarm and call are transmitted on the emergency talk group or announce-ment group that has been preprogrammed by your system operator on the currently selected channel. Proceed as follows:1. To transmit an emergency alarm, select a SMART-NET/SmartZone channel that has that feature enabled and then press the Emergency option switch.2. The emergency alarm is then transmitted and “EMERGNCY” is indicated in the display for a short time. Transmitting continues until an acknowl-edgment is received (indicated by two beeps) or the programmed number of attempts have occurred. Silent operation may also be programmed in which case no audio or visual indication of the alarm con-dition occurs.3. To transmit an emergency call, press the Emergency option switch with a SMARTNET/SmartZone chan-nel selected that has that feature enabled. Then man-ually press the PTT switch and begin speaking as
OPERATION2-24 September 2001Part No. 001-5100-001with a standard call. All calls that follow are then emergency calls and they occur on the emergency talk group. 4. To exit the emergency mode, power must be turned off and then on again. 2.7.11 FAILSOFT OPERATIONIf a failure occurs in the SMARTNET/Smart-Zone system so that it cannot be used, the transceiver automatically enters the failsoft mode. When this mode is selected, the display alternately indicates “FAILSOFT” and the alias of the selected channel.When in the failsoft mode, operation is in the conventional mode on a preprogrammed failsoft channel. If a transmission is attempted before a failsoft channel is located, a continuous tone sounds until the PTT switch is released. When the radio system returns to normal operation, this condition is automatically detected and normal operation resumes. 2.7.12 SMARTNET/SMARTZONE SCANNINGScanning on a SMARTNET/Smartzone channel is similar to the standard and radio wide scanning described in Section 2.5. Each channel can be programmed with a different scan list that includes up to 16 channels, one of which can be a priority channel. These scan lists are user programmable if the Scan Edit option switch is programmed, and nuisance chan-nels can be temporarily deleted (see Section 2.5.8).Scanning is enabled/disabled by the Scan option switch. In addition, channels can be programmed so that scanning automatically starts whenever the channel is selected. Scanning is temporarily disabled and “Scan” turns off if a channel is selected that has scanning disabled. Then when a channel is selected again that permits scanning, it is automaticallyre-enabled. In addition to calls on channels in the scan list, pages, private calls, and telephone calls are received while scanning. Messages on the priority channel are received while listening to lower priority messages. However, private and telephone calls are not inter-rupted by calls on the priority channel. When responding to messages in the scan mode, programming determines if the response always occurs on the talk group of the call or the selected talk group (if they are different). Transmissions occurring at other times always occur on the selected talk group.2.7.13 DYNAMIC REGROUPINGThe dynamic regrouping feature allows a dispatcher to switch users to a dynamically defined channel to receive an important message. Dynamic regrouping operates as follows:1. When this command is received, the alternating dynamic regrouping tone sounds, the transceiver automatically changes to the regrouping channel, and the display alternately indicates “REGROUP” and the alias of the selected channel. All transmit-ting and receiving then occurs on this channel. 2. To reset all talk and announcement groups to normal so that only the designated regrouping channel is on the dynamic group, manually select the designated regrouping channel if you know it. If this channel is not selected or there is no designated regrouping channel, all transmissions occur on the dynamically assigned group regardless of which channel is selected, and the regrouping tone sounds each time the PTT switch is pressed. 3. When regrouping is canceled by the dispatcher, transceiver operation returns to normal. 2.7.14 SMARTZONE FEATURESIntroductionAs described in Section , the SmartZone® mode provides wide area coverage by allowing roaming between SMARTNET and conventional sites. Smart-Zone operation is the same as SMARTNET with the following additional features.Determining Current SiteTo determine the current radio site, momentarily press the Site Search option switch (if programmed). If currently registered on a site, “SITE x” is displayed, where “x” is the site number. The display then indi-cates the RSSI (Receive Signal Strength Indicator)

Locking/Unlocking a SiteIt is sometimes desirable to stay on the current site regardless of signal level. To lock the radio on the current site so that it does not search for another, press the Site Lock option switch (if programmed). The display then momentarily indicates “LOCK x” to indi-cate that the current site is locked (“x” is the current site number). To unlock the site, press the Lock switch again and “UNLOCK” is momentarily displayed. When locked on a site, it is still possible to search for a different site using the site search function described in the preceding section. When a new site is found, the radio is then locked on that site.2.7.15 SMARTNET/SMARTZONE SECURE COMMUNICATIONOn analog SMARTNET/SmartZone channels, either the SecureNet or 460 protocols can be selected. Operation is similar to conventional channel secure communication described in Section 2.6.17.On digital SMARTNET/SmartZone channels, only the DES-OFB protocol is available. Talk groups can be strapped to Clear, Coded, or Switch selectable, and clear and secure messages are alwaysautodetected.The following calls require their own encryption key selection: emergency, failsoft, patch, telephone, private, and system-wide.2.8 SUPERVISORY TONES Single Beep (Alert Tone)•Power was turned on and a successful power-up sequence occurred (see Section 2.4.2).•The time-out timer is about to expire or the penalty timer has expired (Sections 2.4.10 and 2.6.7).•The conversation timer is about to expire (Section 2.6.8). •The system received your page but the paged mobile is not on the air (Section 2.7.7).•Telephone interconnect is not operational (Section 2.7.6).Continuous Tone (Invalid or No AcknowledgeCondition)•A transmission is being attempted on an unpro-grammed channel or a conventional channel programmed as receive-only.•The transmitter is disabled by the busy channel lockout feature (Section 2.6.5).•The transmitter has been disabled by the time-out timer feature (Section 2.4.10).•The transmitter has been disabled by the conversa-tion timer (Section 2.6.8).•An out-of-range condition exists (SMARTNET/SmartZone only).•A transmission is being attempted before the penalty timer has expired (Section 2.6.7).•Dynamic regrouping has been exited but the dynamic regrouping channel is still selected (Section 2.7.13).•The paged mobile did not acknowledge the page (Section 2.7.7).•The message that was sent has not been acknowl-edged (Section 2.7.8).•The status condition that was sent has not been acknowledged (Section 2.7.9).Single Short Medium-Pitch Tone•A valid key has been pressed.Single Short Low-Pitch Tone•An invalid key has been pressed.Six Beeps (Recurring)•The page was received (Section 2.7.7).Three Beeps (Recurring)•A unit-to-unit call was received (Section 2.7.4).
