Refer to page 29 for more information. - The lines above the zone and channel displays indicate which display is changed if the Select switch is turned. To switch between displays, press the Select switch (see page 18). - When this triangle is displayed, the scan list edit mode is indicated (see page 25).

GENERAL OPERATION17GENERAL OPERATIONTurning Power OnWhen power is turned on by pressing the On-Off/Volume knob, the multi-function indicator flashes green, a series of beeps sound, and an initial greeting and operating mode are indicated by the alphanumeric display. The zone and channel displays then indicate the currently selected zone and channel. Programming determines if the last selected or home zone is selected at power up.Backlight Control and Display Viewing Angle Adjust The backlight for the display and option keys can be manually turned on and off if the BKLHT option switch is programmed. Otherwise, it is fixed in the on or off mode by programming. If the display is difficult to read from the angle you normally view it, the viewing angle can be adjusted. Simply press and hold the last option switch above the display and then press the first option switch above the display. Then release both switches and turn the Select switch until the best contrast is obtained. This function times out in 3-5 seconds.Setting Volume LevelThe relative volume setting can be determined by noting the position of the index on the On-Off/Volume knob. Otherwise, enable a reference tone for use in setting the volume as follows:•If the key press tones are enabled (see page 20), a short tone sounds when an option switch is pressed or the Select switch is pressed or rotated.•If a conventional channel is selected, take the microphone off-hook and if someone is talking, voice is heard. If the MON (Monitor) option switch is programmed (see page 29), pressing it unsquelches the trans-ceiver and either voice or background noise is heard. If a SMARTNET/SmartZone channel is selected, the transceiver cannot be manually unsquelched.

GENERAL OPERATION18Zone/Channel Display The selected zone and channel are displayed by the zone and channel displays shown in Figure 3 on page 15. In addition, a unique alphanumeric identification tag (alias) is displayed for each channel in the alphanumeric display area. This unique identification is programmed by your system operator. A zone can include any mix of channels. Up to 16 zones can be programmed, and up to 16 channels can be programmed in each zone for a total of up to 256 channels. Zones may be used for operation in different geographical areas or radio systems. Consult your system oper-ator for more information on how to use the zones and channels that have been programmed in your transceiver.Zone/Channel Select The front panel Select switch is used to change the zone and channel. Pressing this switch toggles between the zone and channel select modes, and rotating it changes the zone or channel.The current mode is indicated by the bar over the zone or channel display. For example, when the bar is over the zone display (see following illustration), the zone select mode is enabled. Rotating the Select switch clockwise increases the zone or channel and rotating it counterclockwise decreases the zone or channel number. After theZoneNo.ChnlNo.Zone Select IndicatorChannel Select Indicator

GENERAL OPERATION19highest zone or channel is displayed, wrap-around to the lowest zone or channel occurs and vice versa. If an unprogrammed channel is selected, “UNPROGRAMD” is displayed and a tone sounds. The transceiver may also be programmed so that only programmed channels are selected.The transceiver can be programmed so that the bar defaults to either the zone or channel display when power is turned on and after a change is made. The delay that occurs before it returns is programmed for 1-15 seconds or infinite (“infinite” causes it to remain in the last selected mode). Setting Squelch ControlThis transceiver does not have a squelch control. The squelch level is preset and usually does not require readjustment. However, if the squelch level needs to be changed on a conventional channel, it can be changed using keypad programming if available (see page 43).Option SwitchesThe six option switches on the front panel (one is located to the left of the display) can be programmed by your system operator to control a different set of functions for each of the two different operating modes (see page 27). Refer to page 9 for more information on these switches. 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 from 15 seconds up to 3 minutes, 45 seconds or it can be disabled. If the transmitter is keyed continuously for longer than the programmed time, the transmitter is disabled, a continuous tone sounds, and “TX TIMEOUT” is displayed. Five seconds before time-out occurs, a warning beep 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

GENERAL OPERATION20prevent possible transmitter damage caused by transmitting for an exces-sively long period.Home Zone SelectIf the HOME zone option switch is programmed, pressing it selects the preprogrammed home zone. This provides a quick way of returning to the home zone. The transceiver may also be programmed so that when-ever power is turned on, the home or last selected zone is automatically selected.Tone SelectThe various alert tones that sound are described starting on page 56. These tones can be enabled and disabled if the TONE option switch is programmed. To turn all tones off, press this switch and “TONE OFF” is displayed. Then to turn all tones on again, press it and “TONE ON” is displayed. If this switch is not programmed, tones are fixed in the on or off condition by programming.Power Turn-Off DelayYour transceiver can be installed so that the vehicle ignition switch as well as the front panel power switch control transceiver power. If this is the case, both the ignition switch and the front panel power switch must be on for transceiver power to turn on.When the ignition switch controls power, a turn-off delay of up to 254 minutes can be programmed. The delay can be overridden at any time by turning power off using the front panel power switch or turning the ignition switch back on. A turn-off delay allows calls to be received for a time after the ignition switch is turned off. At the same time, advan-tages of ignition switch control are utilized such as preventing the battery discharge that may occur if the transceiver is left on for an extended period (see page 59).

GENERAL OPERATION21ScanningIntroductionScanning monitors the channels in the scan list for messages your transceiver is programmed to receive. When a message is detected, scan-ning stops and the message is received. Shortly after the message is complete, scanning resumes (unless it has been disabled). The micro-phone must on-hook for scanning to occur (unless the transceiver is programmed to not detect the off-hook condition).There are two scan modes available: Standard and Radio Wide. The standard type is unique to the type of channel selected, and the Radio Wide type is the same for all channel types. Only one type of scanning can be enabled at a time. Therefore, if standard scanning is enabled when the Radio Wide Scan switch is pressed, standard scanning is automati-cally disabled and vice versa. Refer to the following for more information.Standard ScanningStandard scanning monitors only channels that are the same type as that currently selected. For example, if a conventional channel is selected, only conventional channels are scanned. Standard scanning operates as follows.•To turn standard scanning on, press the SCAN option switch. Scanning is enabled when a rotating is indicated in the right status display asfollows and “SCAN ON” is briefly displayed. Scan Enable Indicator

GENERAL OPERATION22•To turn scanning off, press the SCAN option switch again and is no longer indicated in the status display 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 page 23).Radio Wide ScanningRadio wide scanning monitors the channels in the preprogrammed radio wide scan list. This list may contain up to 16 channels of any type assigned to any zone (see scan list description on page 23). Radio wide scanning is turned on and off by the RWS option switch as follows. If this switch is not programmed, radio wide scanning is not available. •To turn radio wide scanning on, press the RWS option switch and “RSCN ON” is briefly displayed. In addition, is displayed the same as with standard scanning. •To turn radio wide scanning off, press the RWS option switch again and “RSCN OFF” is briefly displayed and is no longer displayed.•If the zone or channel is changed while radio wide scanning, scanning continues normally.Scan Resume DelayWhen a message is received or transmitted while scanning, there is a system operator programmed 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.Transmitting in the Scan ModeIf the transmitter is keyed while scanning is enabled, the transmis-sion may occur on the receive, selected, or priority channel depending on the operating mode and programming.

GENERAL OPERATION23Standard Mode Scan List NOTE: 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 on page 33. Selecting another conventional channel does not change the current scan list. The scan lists are user program-mable if the SCN ED (Scan Edit) option switch is programmed (see page 25). With SMARTNET/SmartZone operation, each channel can be programmed so that one of up to three different scan lists is selected or scanning is disabled. As with conventional channels, the selected scan list is user programmable if the SCN ED option switch is programmed. 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. Determining Which Channels are in Scan ListChannels in the radio wide and conventional standard scan lists are determined as follows. Channels in the SMARTNET/SmartZone standard scan lists are indicated only when editing a list (see page 25).1. Enable Standard scanning to view the standard list or Radio Wide scan-ning to view the radio wide scan list (the procedure is on page 21). With conventional standard scanning which can have up to three lists, also select the scan list if applicable as described on page 33. 2. Select the desired zone and then scroll through the channels by rotating the Select switch. When the displayed channel is in the scan list (scanned normally), the symbol is displayed next to the zone number as shown in the following illustration.

GENERAL OPERATION24Nuisance Channel DeleteWith standard scanning, channels can be temporarily 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 also 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 a tone sounds (approximately 2 seconds). 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 changing channels (SMARTNET/SmartZone) or using the SCAN option switch (conventional).Scan List Indicator ChnlNo.

GENERAL OPERATION25Programming a Scan ListIf the SCN ED (Scan Edit) option switch is programmed, conven-tional and SMARTNET/SmartZone standard scan lists can be user programmed as follows:1. Make sure that both standard and radio wide scanning are off (the rotating icon is not indicated in the right status display). Then press the SCN ED option switch and the scan edit mode is indicated by a triangle in the upper left part of the display (see illustration on page 15). 2. With conventional channels, if applicable, select the list to be edited (1-3) by rotating and then pressing the Select switch. The scan list is indicated as “SCAN LIST x” (see page 33). If user programming is disabled on a list, “NO LIST” is momentarily displayed and it cannot be edited.With SMARTNET/SmartZone channels, the scan list for the selected channel is fixed and cannot be changed. Scanning may also be disabled on the selected channel in which case “NO LIST” is momentarily displayed and scan list editing is not available.3. Select the channel you want to add or delete by rotating the Select switch. After the last channel in the current zone is displayed, the first valid channel in the next zone is displayed and vice versa. SMARTNET/SmartZone lists are limited to 16 channels. If an attempt is made to add more than 16, “LIST FULL” is displayed and a channel must be deleted before another can be added.4. If the selected channel is in the scan list (scanned), the symbol is displayed next to the zone number as described on page 23. To change the scan list status of the displayed channel, press the Select switch. NOTE: The priority channel cannot be deleted (see “Priority Channel Sampling” description which follows).5. To exit this mode and save the changes, press the SCN ED option switch again.

GENERAL OPERATION26Secure Communication GeneralThis transceiver may be optionally equipped to provide secure communication on some or all channels. This feature encrypts your voice so that it can be understood only by someone using a transceiver equipped with a similar encryption device and encryption codes. If your transceiver has this feature, consult your system operator for more infor-mation on how it functions in your application.When a secure call is received or transmitted, is indicated in the display. Secure communication can be programmed on a per channel basis to operate in various ways. If equipped with the C/S (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. In the receive mode, secure calls may be autodetected or only calls coded like the transmit signal may be received. Hardware Key SelectWith SecureNet encryption, up to sixteen hardware keys can be programmed into the transceiver, and then each encrypted channel is programmed to select a specific hardware key. The hardware key is actu-ally the location in the transceiver of the encryption key that is used for a call. The same encryption key may need to be selected in both the trans-mitting and receiving transceivers for secure communication to occur. If multiple keys have been programmed, the Hardware Key Select option switch (if available) can be used to change the key associated with a channel. This permanently changes the key for the channel (cycling power or selecting another channel does not re-select the original key). Therefore, to switch back to the original key, it must be manually reselected. Proceed as follows to change a key:1. Select the desired channel. Then press the Hardware Key Select option switch and “HWKEY x” is displayed. The “x’ indicates the currently selected key from 0-15.

GENERAL OPERATION272. To select another key, rotate the Select switch to display the desired key and then press the Select switch to select it. Press the Hardware Key Select switch again to return to normal operation.Transceiver Operating ModesEach selectable channel can be programmed for either the conven-tional 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. Consult your system operator to deter-mine the type or types of operation programmed in your transceiver. More information on these modes follows.Conventional - This is a non-trunked operating mode which accesses independent radio channels (there is no automatic access to several chan-nels). 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. Channel monitoring and other operating features unique to conventional channels are described starting on page 28.SMARTNET™/SmartZone® -This is a trunked operating mode that uses ID codes to select what mobiles are being called and what calls are received. Monitoring is performed automatically 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. Operating features unique to SMARTNET/SmartZone channels are described starting on page 44.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 condition or the system ID is not correct, for example), “NO SYS” is displayed and the radio continues to search for a control channel.

CONVENTIONAL FEATURES28The 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 informa-tion 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.CONVENTIONAL FEATURESIntroductionAn overview of the conventional operating mode is located on the preceding page. The following information describes the features unique to standard (analog) and Project 25 digital conventional operation. Refer to the preceding “General Operation” section for information on features common to all operating modes.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 conversation. Monitor conven-tional channels automatically or manually as follows:Automatic Channel MonitoringIf the selected channel is programmed for Busy Channel Lockout feature (consult your system operator), monitoring is performed automat-ically. Refer to the description of this feature on the next page for more information.Manual Channel MonitoringThe automatic monitoring just described may occasionally disable the transmitter when the channel is not in use. In this case, it may not be used and the channel must then be monitored manually as follows:

CONVENTIONAL FEATURES29Busy Indicator - With scanning disabled, note if the multi-function indicator on the front panel (see Figure 1 on page 13) 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 using the monitor mode which follows.Monitor ModeThe Monitor Mode temporarily disables squelch control features (such as Call Guard squelch) so that all messages are heard on the channel. To enable the monitor mode, briefly press the SEL SQ option switch (if available) so that “Normal” is briefly displayed. Then to return to normal operation, press this switch again (see page 30 for moreinformation). The monitor mode can also be enabled by taking the microphone off-hook (if off-hook detection is enabled by programming). This also temporarily disables scanning if applicable. To return to normal opera-tion, place the microphone back on-hook. If the MON option switch is programmed, it can also be used to enable monitoring and disable scanning. When monitoring is enabled by this switch, “MON” is indicated in the display (see Figure 3 on page 15). Pressing it a second time returns to normal operation. This function unsquelches the receiver so that all activity, including background noise, is heard. Therefore, it may also be useful during weak signal conditions if intermittent squelching is making a message difficult to understand.Pressing and holding the MON switch for at least 2 seconds when scanning monitors the current scanned channel instead of the selected channel (which may be different when receiving a call).

CONVENTIONAL FEATURES30Busy 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 the transmitter is disabled by this feature, “BUSY” is displayed and a tone sounds. This feature is programmed to operate for one of the following modes:Off - The feature is disabled and the transmitter keys even if the channel is busy.Noise - The transmitter is disabled if any signal is detected on the channel.Tone - The transmitter is disabled if the detected squelch coding is not correct.If busy channel override is enabled by programming, it is possible to transmit when the transmitter is disabled by this feature. Simply release the PTT switch and then quickly press it again.Call Guard SquelchGeneralCall Guard® squelch (also called CTCSS/DCS or selective signaling) may be programmed on conventional channels. This feature eliminates distracting messages intended for others using the channel. This is accomplished by using a subaudible tone or digital code to control the squelch. This tone or code is unique to a user or talk group on that channel. It is transmitted by the mobile placing a call, and if Call Guard squelch is programmed in the mobile receiving the call, it must detect the correct tone or code to receive the call.Call Guard Squelch Enable/DisableThe SEL SQ option switch (if available) can be used to temporarily disable receive Call Guard squelch on the current channel. When it is disabled, “NORMAL” is flashed in the display, and when it is enabled, “SELECTIVE” is flashed. It is automatically re-enabled when another

CONVENTIONAL FEATURES31channel is selected or transceiver power is turned off and on. Call Guard squelch can also be disabled by taking the microphone off-hook or pressing the MON option switch as described on page 29. Selective (Call Guard) Code SelectIf the Selective Squelch Select option switch is programmed, the Selective Squelch (Call Guard) code can be temporarily changed. This switch is used to select a code from a pre-programmed list of up to 16 codes. Proceed as follows to change a code using this switch:1. Press the Selective Squelch option switch and then rotate the Select switch to select the desired code. The display indicates “SEL SQ xx” where, “xx” is the selected code from 1-16.2. To select the displayed code and return to the normal operation, press the Selective Squelch switch again. 3. To check which code is selected, press the Selective Squelch switch once to display the current selection and then again to return to normal operation.4. To return to the normal selective squelch codes, select “DEFAULT” in this mode. The normal codes are also automatically reselected when-ever transceiver power is cycled or a talk-around channel is selected.NOTE: Call Guard codes can also be changed using the keypadprogramming function described on page 38.Penalty TimerA penalty timer may be programmed on conventional channels to prevent transmissions for a short period of time after the time-out timer disables the transmitter (see page 19). 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. When the penalty timer expires, a beep sounds and the transmitter can then be keyed.

CONVENTIONAL FEATURES32Conversation TimerBesides the time-out timer described on page 19 and the penalty timer just described, there is also a conversation timer that can be programmed with conventional channels. This timer limits the total length of a conversation rather than just the length of each transmission as with the time-out timer. If this timer is used, a warning tone sounds 5 seconds before it expires. Then when it expires, the transmitter is disabled and a warning tone sounds. The transmitter remains disabled for the length of the penalty time just described, and a beep sounds when it can be keyed again. Repeater Talk-AroundNormally, all your transmissions go through a repeater which usually increases range. However, if you are out of range of the repeater, you cannot talk to anyone else on that repeater even though the mobile you are calling may be only a short distance away. To allow communica-tion when this situation occurs, repeater talk-around can be selected to allow direct mobile-to-mobile communication.Repeater talk-around can be selected if the RTA option switch is programmed. When talk-around is enabled by this switch, “RTA ON” is flashed in the display, and when it is disabled, “RTA OFF” is flashed. This feature remains enabled during scanning, and changing channels or turning power off does not change the selected mode.Power Output SelectIf the Tx PWR option switch is programmed and selectable power is permitted on the current channel, high and low transmitter power can be selected. Generally, the high power setting allows you to transmit longer distances but uses more battery power. The opposite occurs with the low power setting.

CONVENTIONAL FEATURES33Pressing the TX PWR switch toggles the power setting. The new level is flashed in the display when this switch is pressed as “HIGH POWER” or “LOW POWER”. If selectable power is not permitted on the current channel, the fixed power level is flashed and no power change occurs.Displaying Transmit/Receive FrequencyIf the DISP option switch is programmed, it can be used to display the channel frequency in megahertz. Pressing this switch toggles between displaying the standard channel identification and the frequency. The receive frequency is displayed while receiving and the transmit frequency is displayed while transmitting.Emergency ModeAn EMER option switch may be programmed for use on conven-tional Project 25 (digital) channels. This function could be used, for example, to alert your dispatcher of an emergency condition. If you have this switch, consult your system operator for more information on how it is used in your application.Conventional Mode ScanningGeneralThe following information describes scanning features unique to conventional operation. Scan operation common to all modes is described starting on page 21, and scan operation common to SMARTNET/Smart-Zone operation is described starting on page 54.Selecting Scan ListUp to three scan lists are available when standard scanning with a conventional channel selected. These lists are preprogrammed by your system operator, and the list to be scanned is selected by the SCAN option switch as follows:

CONVENTIONAL FEATURES341. Press the SCAN option switch to enable scanning and Scan List 1. This is indicated when “SCAN LIST 1” is momentarily displayed. 2. To select Scan List 2 (if available), press the SCAN option switch again and “SCAN LIST 2” is momentarily displayed. Repeat to display Scan List 3 if available. 3. To disable scanning, press the SCAN switch again. Scanning is disabled when scan indicator is no longer displayed.Transmitting in Scan ModeWhen the transmitter is keyed with scanning enabled, the transceiver can be programmed so that the transmission always occurs on one of the following channels: •Priority channel (see following)•Selected channel•Channel of a call if the response is made before scanning resumesPriority Channel SamplingGeneralThe priority channel sampling feature ensures that 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. Priority channel sampling occurs only with Standard 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 when the priority channel is sampled while listening to a message on some other channel. When the selected channel is a priority channel, “P” is indicated in the left status display next to the zone number as follows:

CONVENTIONAL FEATURES35Changing The Priority ChannelIf a specific priority channel is associated with the current scan list, it can be changed if the PRI SEL option switch is programmed. Proceed as follows:1. Make sure that both standard and radio wide scanning are off (the rotating icon is not indicated in the right status display).2. Select the channel that you want to be the priority channel using the Select switch in the normal manner. If the channel is in a different zone, also select the appropriate zone.3. Press the PRI SEL option switch and “P” is indicated in the left status display as just described to indicate that the selected channel is now the priority channel.Standard Conventional CallsStandard conventional calls can be placed to other mobile units monitoring the selected channel. The proper coded Call Guard squelch tone or code may need to be transmitted by your transceiver for them to receive your call (see page 30).Placing a Standard Conventional Call1. Turn power on and set the volume as described on page 17. Select the channel programmed for the mobile you want to call (see “Zone/Channel Select” on page 18).Priority Indicator

CONVENTIONAL FEATURES362. Monitor the channel automatically or manually as described on page 28.3. 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 description on page 30). •Otherwise, busy and out-of-range conditions are not indicated and speaking can begin after monitoring the channel. 4. Press (and hold) the PTT switch to talk and release it to listen. When the call is finished, place the microphone back on-hook.Receiving a Standard Conventional Call1. Select or scan the channel programmed for the call you want to receive (refer to pages 21 and 33 for more scanning information).2. When the call is received, take the microphone off-hook and 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. 3. When the call is finished, place the microphone back on-hook.Project 25 Mode FeaturesViewing 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.

CONVENTIONAL FEATURES37Group IDsEach Project 25 channel is programmed with a group ID code that determines the group of mobiles which will receive your call on that channel and also which calls you can receive.Coded SquelchProject 25 conventional channels use a NAC (Network Access Code) instead of Call Guard squelch (see page 30) to control which calls are received on a channel. Both the correct group ID and NAC must be detected to receive a call. However, other operation, such as monitoring, is similar to when Call Guard squelch is used.Changing Talk Group Assigned To A ChannelIf the TG SEL option switch is programmed, the talk group assigned to a channel can be changed. This change is permanent (cycling power does not reselect the old talk group). Proceed as follows:1. Select the channel to be changed and then press the TG SEL option switch.2. Rotate the Select switch to display talk group to be assigned to that channel. Talk groups are indicated by a unique identification in the alphanumeric display.3. To select that talk group and return to normal operation, press the TG SEL switch again or press the Select switch. If talk group selection has been disabled on the channel by programming, the talk group does not change, “NO LIST” is displayed, and a tone sounds.Individual CallsIf the CALL option switch is programmed, 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

CONVENTIONAL FEATURES38press the PTT switch and begin talking before a call timer expires. Proceed as follows to place this call:1. Press the CALL option switch and the identification of the last indi-vidual call placed is displayed.2. If required, rotate the Select switch to display the identification of the mobile you are calling.3. Press the PTT switch and begin talking. When individual calls are received, the transceiver may be programmed to display the selected talk group, the talk group of the call, or the ID of the calling radio.Keypad ProgrammingIntroductionKeypad programming is available if the PROG option switch is programmed. It is then selected by simply pressing that switch. The keypad programming mode is indicated by “ZONE CHG” and blanked Zone and Channel displays as follows:Keypad programming allows conventional channel parameters such as the transmit and receive frequency and Call Guard squelch code to be changed. In addition, several conventional mode timers can be changed. It cannot be used to reprogram unavailable channels or any SMARTNET/SmartZone information.

CONVENTIONAL FEATURES39Menu DescriptionA menu system is used to select parameters to be changed in the keypad programming mode. When the Keypad Programming mode is selected by pressing the PROG option switch, the first menu parameter “ZONE CHG” is displayed as just described.

Press and then release the PTT switch and “DIALING” is displayed. One of the following conditions then occur:•If the access is successful, a dial tone sounds and the dialed number is displayed and sent. Either ringing or a busy signal is then heard as with a standard telephone call. When the called party answers, press the PTT switch to talk and release it to listen (since the transceiver operates half-duplex, it is not possible to talk and listen at the same time). Each time the PTT switch is released, a go-ahead tone is sent to the landside party to indicate when they can respond. To dial a number after the connection is made, press the PTT switch and dial the number using the microphone keypad (if available).•If the selected telephone number is not valid, “INVALID” is displayed and an alert tone sounds. Select a valid number.•If the system is busy, “BUSY” is displayed and the busy tone sounds. The call will automatically proceed when the system becomes available.•If you are out-of-range or the radio cannot be accessed for some reason, “NO PHONE” is displayed and an alert tone sounds.•If the interconnect call you are making or the selected secure mode is not authorized, “REJECT” is displayed and an alert tone sounds.•If your transceiver does not have the proper encryption key, “KEYFAIL” is displayed and the call must be made in the clear mode (selected by pressing the C/S (Clear/Secure) option switch if enabled on the channel).4. When the telephone call is finished or it could not be completed for some reason, end it by pressing the PHONE option switch and placing the microphone back on-hook.

To answer the call, press the PHONE option switch and press the PTT switch to talk and release it to listen (since the transceiver operates half duplex, it is not possible to talk and listen at the same time).3. When the call is finished, end it by pressing the PHONE option switch and placing the microphone back on-hook.Call Alert The Call Alert™ feature allows pages to be sent and received. Either the Enhanced Private Conversation™ or Private Conversation II™ mode may be programmed depending on the capabilities of the radio system. The operation differences are noted in the procedure which follows.Answering a Page1. When a page is received, four beeps sound and “PAGE” is displayed. The ID of the mobile paging you is stored as the last ID received.2. To clear or ignore the page, press any option switch. If the PTT switch is pressed, a group call is placed on the selected channel.3. To answer the page as a private call (see page 45), press the CALL (Private Call) option switch and the tag (alias) of the mobile paging you is displayed. Press the PTT switch and respond. One of the conditions that follow may also occur:Enhanced Private Conversation™ Mode•If the mobile being called is on the air, ringing is heard until the called party answers or for 20 seconds, whichever occurs first. If no answer occurs within 20 seconds, “NO ANS” is displayed.

SMARTNET/SMARTZONE FEATURES51•If the mobile being called is not on the air, no ringing is heard and “NO ACK” is displayed.Private Conversation II™ Mode•If the mobile being called is not on the air or does not answer, you will simply not hear a response.4. When the call is finished or it could not be completed for somereason, end it by pressing the CALL option switch and placing the microphone back on-hook.Initiating a Page1. With a SMARTNET/SmartZone channel selected, momentarily press the ALERT option switch. The tag (alias) of the last ID called is displayed.2. If required, rotate the Select switch to display the desired mobile. The tag of each number is displayed. 3. Press the PTT switch and one of the following then occur:•If a continuous tone sounds, the system received the page but the called mobile is not on the air. Try again later or cancel the page by pressing the ALERT switch again.•If the called mobile does not answer within 6 seconds, a continuous tone sounds and “NO ACK” is displayed. Try again later or cancel the page by pressing the ALERT switch again. •If five beeps sound, the system received the page and the paged mobile is on the air and received it. The normal mode is automati-cally reselected.

SMARTNET/SMARTZONE FEATURES52MessagingThe messaging feature allows preprogrammed messages to be sent to your dispatcher. Up to 16 messages can be preprogrammed, and they are identified by a tag (alias). If an MSG option switch is programmed, messages are sent as follows:1. Momentarily press the MSG option switch. The tag of the last message sent is displayed.2. If required, rotate the Select switch to display the desired message. Then send the message by momentarily pressing the PTT switch. One of the following then occurs:•If five beeps sound, the message was received and acknowledged by the dispatcher.•If after 6 seconds, the message is not acknowledged, a tone sounds, and “NO ACK” is displayed. Press and release the PTT switch to send it again or press the Message option switch to exit the messaging mode.Sending Status ConditionsThe status feature allows you to manually or automatically send your current status to your dispatcher. Up to eight status conditions can be preprogrammed, and they are identified by a tag (alias). If the STATUS option switch is programmed, status conditions are sent as follows:1. Momentarily press the STATUS option switch. The tag of the current status condition is displayed.2. To change the current status, rotate the Select switch until the desired status is displayed. Then press the Select switch to accept that status.3. You can wait to send the current status until polled by the dispatcher or it can be sent immediately by briefly pressing the PTT switch. One of the following then occurs:

SMARTNET/SMARTZONE FEATURES53•If five beeps sound, the status was received and acknowledged by the dispatcher.•If after 6 seconds, the message is not acknowledged, a tone sounds and “NO ACK” is displayed. Press and release the PTT switch to send it again or press the Status option switch to exit this mode and return to normal operation.Emergency Alarm and Emergency CallEmergency alarms and emergency calls are separate functions that can be individually programmed on SMARTNET/SmartZone channels. The EMER option switch is also required to have these functions. An emergency alarm is a special data transmission 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 programmed emergency talk group. Proceed as follows to initiate an emergency alarm or call:1. To transmit an emergency alarm, select a SMARTNET/SmartZone channel that has that feature enabled and then press the EMER option switch.2. The emergency alarm is then transmitted and “EMERGENCY” is indicated in the display for a short time. Transmitting continues until an acknowledgment is received (indicated by two beeps) or the programmed number of attempts have occurred. 3. To transmit an emergency call, press the EMER option switch with a SMARTNET/SmartZone channel selected that has that feature enabled. Then manually press the PTT switch and begin speaking as with a stan-dard 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.

SMARTNET/SMARTZONE FEATURES54Failsoft OperationIf a failure occurs in the SMARTNET/SmartZone system so that it cannot be used, the transceiver automatically enters the failsoft mode. When in this mode, “FAILSOFT” and the tag (alias) of the selected channel are alternately displayed.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. The secure mode is controlled by the C/S (Clear/Secure) option switch and indicated by in the display. Secure calls are always automatically detected.SMARTNET/SmartZone ScanningScanning on a SMARTNET/Smartzone channel is similar to the standard and radio wide scanning described starting on page 21. Each channel can be programmed with a different scan list that includes up to 16 channels, on of which can be a priority channel. The scan lists are programmable as described on page 25 if the SCN ED (Scan Edit) option switch is programmed. In addition, channels can be programmed so that scanning automatically starts or is disabled whenever the channel is selected. Messages on the priority channel are received while listening to lower priority messages. However, unit-to-unit and telephone calls are not interrupted by priority messages. Pages, unit-to-unit calls, and tele-phone calls are received while scanning.Dynamic RegroupingThe dynamic regrouping feature allows a dispatcher to switch mobiles to a newly defined channel to receive an important message. Dynamic regrouping operates as follows:

SMARTNET/SMARTZONE FEATURES551. When this command is received, an alternating tone sounds for 5 seconds, the transceiver automatically changes to that channel, and the display indicates the tag (alias) of the channel.2. Manually select the channel corresponding to that tag. If this is not done, transmission still occurs on the new channel, but an alternating tone sounds each time the PTT switch is pressed.3. Talk and listen as usual. The dispatcher will cancel dynamic regrouping. If a standard channel is not selected after this occurs, an error tone periodically sounds.SmartZone FeaturesIntroductionAs described on page 27, the SmartZone® mode provides wide area coverage by allowing roaming between SMARTNET and conventional sites. SmartZone operation is the same as SMARTNET with the following additional features:Busy OverrideThe busy override feature allows a call to be placed even if all of the sites you are calling do not have a free traffic channel. This feature is enabled and disabled by the system manager, and it operates as follows:1. Assume that you have attempted to place a call and the system was busy (“BUSY” displayed and busy tone sounded). 2. Release the PTT switch and then press it for 5 seconds or more. If a chirp-like tone sounds with the PTT switch pressed, busy override is occurring.NOTE: Remember that not all members of the talk group are receiving your message. Missing members will start receiving your message as channels become available.

MISCELLANEOUS56Determining Current Site and Searching For a New SiteTo determine the current radio site and the signal level of that site, press the SEARCH option switch. The display then alternately indicates the current site number as “SITE xx” and the signal level as “RSSI xx”. To exit, press the SEARCH option switch again. To scroll through the other programmed sites, rotate the Select switch while “Site xx” or “RSSI xx” is displayed. To select the displayed site and exit this mode, press the SEARCH option switch again. If site lock is on when site search is entered (see following), the radio will be locked on the new site when this function is exited. Locking/Unlocking a SiteIt is sometimes desirable to stay on a site. To prevent the transceiver from searching for a new site, it can be locked on the current site. To lock on the current site, press the LOCK option switch. The display momen-tarily indicates “LOCK x” to indicate that the current site is locked (“x” is the current site number). To unlock the site, press the LOCK option switch again and “UNLOCK” is momentarily displayed. MISCELLANEOUSSupervisory Tones Single Beep (Alert Tone)•Power was turned on and a successful power-up sequence occurred (see “Turning Power On” on page 17).•The time-out timer is about to expire or the penalty timer has expired (page 19).•The conversation timer is about to expire (page 32). •The system received your page but the paged mobile is not on the air (page 50).•Telephone interconnect is not operational (page 48).

This usually refers to the programming performed by your system operator when the radio was set up, not to any programming that you can perform. If a feature is controlled by a front panel option switch and that switch is not available, it is probably not available.

MISCELLANEOUS59If you require additional information on the operation of a feature, contact your system operator. If the Keypad Programming option switch is available, you can reprogram some conventional channel parameters. Refer to “Keypad Programming” on page 38 for more information.Speaking Into MicrophoneFor best results, hold the microphone about 1-2 inches from your mouth and speak at a normal conversational level. Do not shout since it distorts your voice and does not increase range. Make sure that the PTT (push-to-talk) switch is pressed before you begin to speak and released as soon as the message is complete.Operation At Extended RangeWhen approaching the limits of radio range, the other party may not be able to hear your transmissions and there may be an increase in back-ground 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.Preventing 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.

MISCELLANEOUS60LicensingA government license is usually required to operate this transceiver on the air. Your system operator will normally handle the licensing requirements.Transceiver Service 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. Contact your system operator for service.If no characters or all characters appear in the display, the viewing angle may be incorrect. Refer to page 17 for more information. 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 prop-erly, return it to your system operator for service.NOTE: There are no user-serviceable components in the transceiver. Altering internal adjustments can cause illegal emissions, void the warranty, and result in improper operation that can seriously damage the transceiver.
