Likewise, to increase the selected group, press GRP . Holding the key down causes the function to repeat. After the highest system or group is selected, a tone sounds and wrap-around to the lowest system or group occurs.•To decrease the selected system, press SYS and then . Likewise, to decrease the selected group, press GRP . Holding the key down causes the function to repeat. After the lowest system or group is selected, a tone sounds and wrap-around to the highest system or group occurs.

BASIC OPERATION22•To directly select a system or group number, press SYS or GRP and then the number of the desired system or group. For example, to select Group 9, press GRP, 0, 9 (two digits must also be entered for numbers 0-9).Keypad DisableOccasionally, the front panel keys may be accidentally pressed, for example, if you carry the transceiver on your belt and it brushes against an object. To prevent this from happening, the front panel keys can be disabled by the keypad lock feature. To lock and unlock the keypad, press FCN . The locked condition is indicated by the icon and LOCK in the display. If a key is pressed with the keypad locked, all that happens is “LOCKED” is displayed. The top and side panel controls remain func-tional with this feature selected, and turning power off and then on again does not unlock the keypad. Transceiver LockThe transceiver can be locked to prevent unauthorized usage. To lock the transceiver, press FCN and “PASSWORD” is then displayed to indicate that a four-digit unlock password must be entered. This pass-word can be any four-digit number except “0000”. The password must be re-entered to confirm it and the transceiver is then locked as indicated by “LOCKED” in the display.When the transceiver is in the lock mode, calls cannot be received or transmitted. In addition, all controls except FCN and the on-off/volume control are disabled. To unlock the transceiver, the four-digit password must be re-entered. The transceiver then remains unlocked until it is locked again by repeating this sequence. Since the password is not preprogrammed, a different password can be entered each time this feature is used. If the password is forgotten, the transceiver must be returned to your system operator for reprogramming to make it operational again.

BASIC OPERATION23Low Battery IndicationWhen the battery voltage drops to the point where recharging is required, the icon is indicated in the bottom part of the display, and a beep sounds when this indication initially appears and when the push-to-talk switch is released (if the key press tone is enabled). The battery should be recharged as soon as possible after this indication appears (see page 58). The low-battery indication is turned off by turning power off and then on again. Current settings of switches and other parameters are saved in memory during a low-battery condition, and low transmit power is automatically selected (indicated by “L” in display). If the battery voltage drops to the point where the transceiver no longer operates, all segments in the display are enabled.Option SwitchesThis transceiver has three option switches that can be programmed by your system operator to control various functions (see table on page 36). They are the push-button switch on the top panel and the switch immediately above and the switch immediately below the PTT switch on the side panel (see page 12). LTR-Net, LTR, and Conventional OperationIntroductionEach selectable system can be programmed for LTR-Net, LTR, or conventional operation. The type of operation that is programmed is determined by the radio equipment being used by your system operator. There are a few differences in operation that are described in the following information and also noted elsewhere in this manual as required.

BASIC OPERATION24LTR-Net and LTR OperationThe LTR-Net and LTR modes provide automatic channel selection and monitoring before transmitting. Special tones and display messages indicate busy and out-of-range conditions, and telephone calls can be placed almost as conveniently as with your home telephone. Selecting a system selects a collection of up to 99 groups, and selecting one of these groups selects an ID code which determines the type of call (standard group, telephone, or special) and the specific mobile or mobiles is being called (if applicable) and what calls are received. In addition, higher priority calls may be received (see page 46). The LTR-Net operating mode provides the most operating features. Exclusive LTR-Net features include roaming and Unique ID and Directed Group calls. When operating in LTR-Net sites, calls may be made to mobiles in other sites as well as the current site. LTR-Net and LTR features are described starting on page 46. Conventional OperationIn the conventional mode, selecting a system selects a conventional channel, and selecting a group selects the special Call Guard squelch coding (if used) and other unique parameters on that channel such as call indicator operation. The Call Guard coding determines the mobile or group of mobiles being called and also the mobiles from which calls are received (see “Call Guard Squelch” on page 52).In the conventional mode, a busy condition is detected automatically if the Transmit Disable On Busy feature is used. Otherwise, it must be detected manually as described in “Monitoring Before Transmitting” on page 50. Unsuccessful access conditions cannot be detected with conven-tional signaling, so are not indicated by special tones or display messages. Refer to “Operation At Extended Range” on page 60 for infor-mation on how to determine if an out-of-range condition may exist.

GENERAL FEATURES25GENERAL FEATURESBank SelectA bank is a collection of selectable systems that have been set up for a specific application. For example, one bank could be programmed for operation in Minneapolis and another for operation in Milwaukee. Up to sixteen banks can be programmed, and each bank is identified by a unique alpha tag. Banks are selected by the BANK SEL menu parameter or BANK option switch. In the menu mode select the “BANK SEL” parameter and then the desired bank (refer to page 36 for more menu mode informa-tion). If using the Bank option switch, press the and keys to select the desired bank. If neither the menu parameter nor the option switch is available, banks are not selectable. Call IndicatorThe call indicator is “C” in the upper part of the display (see following illustration). The purpose of this indication is to show that a call was received while you were away from the radio. Individual groups can be programmed for this feature and it then turns on when a call is received on one of those groups. This indicator is turned off by pressing any button or cycling power. If scanning and the “Last Received” configuration is programmed (see “Transmitting In The Scan Mode” on page 45), the system and group of the last call are displayed. Otherwise, the currently selected system/group is displayed.CCallIndicator

GENERAL FEATURES26Emergency SwitchIf the EMER option switch is programmed (see page 35), it is used to quickly select the emergency system/group that has been programmed in the current bank. The emergency call must then be manually trans-mitted by pressing the PTT switch (automatic transmissions do not occur). Scanning continues if it is enabled, and calls are received normally on other systems and groups if applicable. EncryptionEncryption is an optional feature that prevents conversations from being monitored by casual eavesdropping and analog scanners. It does this by encrypting your voice so that it can be understood only by someone using a transceiver equipped with a similar encryption device.Encryption is enabled and disabled by the ENCRYPT menu param-eter or Encryption option switch (see page 35). If equipped with encryp-tion and neither the menu parameter nor the option switch is available, encryption is always enabled. When encryption is enabled, is indi-cated in the display as shown below.To transmit an encrypted call, encryption must be enabled as just described and the selected group must be programmed for encryption. Encrypted calls are always received regardless of the currently selected encryption mode and group programming (if the radio is equipped with encryption). When transmitting an encrypted call, wait approximately 1 second before speaking. This gives the receiving transceiver time to establish synchronization which ensures that all of the first word is received. If the proceed tone is used and an encrypted call is transmitted, two beeps instead of one sound and the tone is automatically delayed for the required time.OEncryptionIndicator

GENERAL FEATURES27Home System/Group SelectTo select the preprogrammed Home system/group, simply press the FCN HOME. The Home system/group is then displayed and it becomes the selected system/group. If no home system/group has been programmed, this function is not available. A different home system/group can be programmed for each bank. Option SelectThe Auxiliary option switch or OPTION menu parameter can be used to control an accessory that may have been installed by your system operator. The enabled condition is indicated by in the display.Power SelectHigh and low transmit power output is selectable if the “TX POWER” menu parameter is available. Select either “LO POWER” or “HI POWER” as described on page 36. When low power output is selected manually or automatically, “L” is indicated in the display (see page 13). Turning power off and then on again does not change the selected power output level. Selecting low power may increase battery life and decrease range, and selecting high power may cause the opposite to occur. The low power mode is automatically selected during a low battery condition (see page 23).Proceed (Clear-To-Talk) ToneThis is a short tone that sounds shortly after the PTT switch is pressed to indicate that the radio system has been accessed and speaking can begin. This tone can be programmed to be a single or distinctive (3-beep) tone. With encrypted calls, a special double beep sounds.This tone always sounds with LTR-Net and LTR standard calls if tones are enabled by the TONES menu parameter (see “Tone Select” on page 29) or system operator programming. It can also be programmed to

GENERAL FEATURES28sound with conventional calls and/or LTR-Net and LTR auxiliary and telephone calls (first access only). On LTR-Net and LTR systems, if the radio system is busy when making a call, the busy tone sounds instead of the proceed tone and “BUSY” is indicated in the display. If an access attempt is unsuccessful, such as because of an out-of-range condition, the intercept tone sounds and “NO ACCES” is indicated in the display. Refer to page 53 for more information on these conditions.If the proceed tone is enabled on conventional systems and the Transmit Disable On Busy feature is used to automatically perform moni-toring (see page 51), the proceed tone does not sound if the channel is busy. Otherwise, it sounds even if the channel is busy. Receive-Only GroupsAny group can be programmed for monitoring only (transmitting disabled). If the PTT switch is pressed with one of these groups selected, the intercept tone sounds and “TX DISBL” is displayed. Stealth ModeThe stealth mode disables all tones and the display backlight so that they do not reveal you are transmitting or otherwise indicate your pres-ence. The speaker audio and display remain enabled. The stealth mode can be selected by the STEALTH menu parameter (see page 35) or it can be fixed in the on or off mode by dealer programming. There is no special indication that this mode is selected except that “On” is briefly displayed when it is selected by the menu parameter. Time-Out TimerThe time-out timer disables the transmitter if it is keyed continu-ously for longer than the programmed time. It can be programmed for 0.5 - 5.0 minutes or disabled entirely. If the transmitter is keyed continuously for longer than the programmed time, the transmitter is disabled, “TIMEOUT” is indicated in the display and the intercept tone sounds. The timer and tone are reset by releasing the PTT switch.

STANDARD GROUP CALLS29One use of the time-out timer feature is to prevent a repeater from being kept busy for an extended period by an accidentally keyed trans-mitter. It can also prevent possible damage to the transmitter caused by transmitting for an excessively long period.Tone SelectIf the TONES menu parameter is selectable, the tones that sound can be selected. Otherwise, the tones that sound are fixed by programming. The following choices are available. Refer to page 36 for more informa-tion on using the menu mode.Silent - All tones are disabled.Keys - Only the key press tones are enabled.Alerts - All tones except the preceding key press tones are enabled.All - Both the key press and alert tones are enabled.STANDARD GROUP CALLSGeneralMost calls you make are probably the standard group type described in this section. These calls are between you and another mobile or control station. The main difference between these calls and the other types is that no number is dialed using a keypad. The following procedure applies to all three types of operation (LTR-Net, LTR, and conventional).Placing a Standard Group Call1. Turn transceiver power on and set the volume as described starting on page 20. With conventional operation, also make sure that the squelch is properly set as described on page 49.2. Select the system and group of the mobile being called as described on page 21.3. If a conventional call is being placed, monitor the channel manually or automatically as described on page 50.

STANDARD GROUP CALLS304. Press (and hold) the microphone PTT (push-to-talk) switch to talk and release it to listen. Operation with LTR-Net, LTR, and conventional calls is as follows:LTR-Net and LTR Operation•If tones are enabled, the proceed tone sounds shortly after the PTT switch is pressed if the radio system was successfully accessed (see page 27). If tones are not enabled, no tone sounds when the system is successfully accessed. •If the radio system is busy, the busy tone sounds (see page 53) and “BUSY” is indicated in the display. Additional access attempts as long as you continue pressing the PTT switch.•If the radio system could not be accessed because of an out-of-range condition or some other reason, the intercept tone sounds (see page 53) and “NO ACCES” is indicated in the display. The PTT switch must then be released and pressed again to make another access attempt. •When responding, busy or no access conditions may also occur the same as when placing a call because the system is re-accessed for each transmission with these calls. Conventional Operation•If the channel is busy and the Transmit Disable On Busy feature is programmed (see page 51), “DSBL BSY” is indicated in the display and the transmitter is disabled. Any channel activity is heard while the PTT switch is pressed.•Otherwise, busy and out-of-range conditions are not indicated and speaking can begin when the PTT switch is pressed (if the channel is not busy). If the proceed tone is enabled on conventional systems, it indicates when speaking can begin but does not indicate that the channel is free or has been successfully accessed.

TELEPHONE CALLS31Receiving a Standard Group Call1. Select or scan the system and group programmed for the call you want to receive (see page 41 for scan information).2. When the message is received, the display changes to the system and group of the call. Press the PTT switch to talk and release it to listen. If scanning, a response may not automatically occur on the group of the call. Refer to “Transmitting In The Scan Mode” on page 45 for more information. TELEPHONE CALLSGeneralNOTE: Telephone calls can be placed and received only if that service is available to you and your transceiver has been programmed appropri-ately. The telephone calling feature allows you to place and receive tele-phone calls using your transceiver. The following information describes how these calls are made with LTR-Net and LTR operation. If you can make telephone calls with conventional operation, the procedure may be somewhat different and your system operator may provide additional information. Proceed as follows:Placing Telephone Calls1. Turn transceiver power on and set the volume as described starting on page 20. 2. Select the dial mode and a telephone group as follows. When the dial mode is selected, the handset portion of the telephone icon is displayed, and then when a telephone group is selected, the base portion is displayed.

TELEPHONE CALLS32•To select the dial mode and a preprogrammed telephone group, press FCN PHONE. •To select the dial mode without changing the selected group, press FCN DIAL. Then manually select a telephone group if required.3. Dial the desired number using the keypad or recall it from memory by pressing FCN RCL and the location number (0-9). Refer to the dial mode description starting on page 38 for more information.4. To automatically access the radio system and send the telephone number, press FCN SND. Landside ringing (or a landside busy condi-tion) should then be heard.The following conditions may also occur:•If the radio system is busy or could not be accessed, busy or no access conditions may be indicated the same as described for stan-dard group calls on page 30.•With LTR-Net operation, a short tone sounds to indicate that the number was accepted by the system. 5. When the other party answers, press the PTT switch and respond. The PTT switch must be pressed to talk and released to listen the same as with standard group calls. 6. When the call is finished, it should be terminated and the dial mode exited. The call is usually terminated by transmitting either the or characters. To automatically send these characters and exit the dial mode, press FCN PHONE. To exit the dial mode without sending these characters, press FCN DIAL. Termination is indicated by three beeps. Terminating the call in this manner prevents extra billing that may occur while the system automatically detects the end of the call.##

LTR-NET AUXILIARY CALLS33Receiving a Telephone Call1. Select or scan the system and group programmed for telephone calls. When a telephone group is selected, the base portion of the tele-phone icon is displayed. 2. When “ringing” is heard, press the PTT switch and respond. The PTT switch must be pressed to talk and released to listen the same as with standard calls.3. When the call is finished, it should be terminated as in step 6 of the preceding section. Landside-Originate Telephone CallsIf telephone calls can be placed, it is usually possible to receive tele-phone calls from a landside telephone. With some radio systems, each mobile is assigned a unique telephone number so that it can be dialed directly. With others, the number of the radio system is dialed and then when a tone sounds, the number specifying the mobile being called is dialed. The mobile user hears “ringing” when a telephone call is received. Contact your system operator for the number to dial and other informa-tion on how to place these calls. LTR-NET AUXILIARY CALLSGeneralThe LTR-Net auxiliary calls are Unique ID and Directed Group calls. Unique ID calls are placed to specific mobiles, and Directed Group calls are placed to specific talk groups. These calls can be made to other mobiles in your site or some other site that is part of your radio network.As with telephone calls, a special number must be dialed to place these calls. The number dialed is 1-10 digits long, and is provided by your system operator. Other requirements to place these calls are they

LTR-NET AUXILIARY CALLS34must be authorized on the radio system and your transceiver must be properly programmed. Refer to page 47 for more information on LTR-Net calls.Placing LTR-Net Auxiliary Calls1. Turn transceiver power on and set the volume as described starting on page 20. 2. Select the LTR-Net system and group programmed for auxiliary calls. When an auxiliary call group is selected, “UID” is indicated in the lower part of the display. If the group alpha tag is displayed, it may also indicate when one of these groups is selected.3. Select the dial mode by pressing FCN DIAL. This mode is indicated when the handset portion of the telephone icon is displayed.4. Dial the desired number which specifies the mobile or group of mobiles being called. If it has been previously stored, this number can be recalled from memory by pressing FCN RCL and the location number (0-9). Refer to the dial mode description starting on page 38 for more information.5. To automatically access the radio system and send the number, press FCN SND. A tone then sounds to indicate that the call was accepted by the system. The call then proceeds as follows. If this tone does not sound, an unauthorized or incorrect number may have been dialed. If all system resources are busy, the call is placed in a queue as described in “Busy Queuing” on page 47.Unique ID Call - Ringing is heard to indicate that the other transceiver is being rung. If there is no answer, ringing automatically stops after several rings and the call is terminated. When the other party answers, respond as with a standard call.Directed Group Call - A second tone sounds to indicate that the path is complete and speaking should begin. No ringing occurs.

OPTION SWITCHES AND MENU MODE356. When the call is complete, it should be terminated the same as described in step 6 on page 32. Three beeps indicate that the call has been terminated. Receiving Auxiliary CallsTo receive a Unique ID call, all that is required is that an LTR-Net system containing a group programmed for those calls be selected. To receive a Directed Group call, the group of the call usually needs to be selected or scanned. A Unique ID call is indicated by a “ringing” tone similar to telephone calls, and a Directed Group call is indicated by the caller’s voice the same as with standard group calls. The transceiver may be programmed so that responses always occur on the last selected group. In this case, the group may need to be manu-ally changed to respond to these calls (see “Transmitting In The Scan Mode” on page 45). Unique ID and Directed Group calls can also be placed from a landside telephone. The same numbers are dialed as when the call is mobile originated. Contact your system operator for more information on how to place these calls.OPTION SWITCHES AND MENU MODEOption SwitchesThe push-button switch on the top panel (see page 11) and the switch immediately above and and the switch immediately below the PTT switch on the side panel (see page 12) are programmable by your system operator. The functions which can be controlled by these three switches are indicated by an “X” in the “Option Switch” column of the following table. More information on each function can be found on the page indi-cated in this table. Some functions may be controlled by both the menu mode and an option switch, and some or all option switches may not be used.

OPTION SWITCHES AND MENU MODE36Menu ModeIntroductionThe menu mode is selected by pressing FCN MENU. Functions which can be controlled by the menu mode are indicated by an entry in the “Menu Items” column of the preceding table. More information on each function can be found on the page indicated in this table. Parameters are not displayed in the menu mode if they are not used, in a fixed state, or controlled by only an option switch. Calls cannot be received or trans-mitted while the menu mode is selected.Using Menu ModeA flowchart of the menu mode is shown on the next page. Proceed as follows to select functions using the menu mode:1. Select the menu mode by pressing FCN MENU.

DIAL MODE38DIAL MODEIntroductionWhen placing calls that require a number be dialed (telephone and auxiliary), using the dial mode allows the number to be dialed at any convenient rate, dialing errors to be corrected, and then the radio system to be automatically accessed and number transmitted when desired. The dial mode also allows up to ten 16-digit numbers to be stored in memory and later recalled. When in the dial mode, the SYS and GRP keys become RCL (Recall) and CLR (Clear) keys. Therefore, the selected system and group cannot be changed when the dial mode is selected. The information which follows describes how the dial mode is used.Selecting Dial ModeSelecting Dial Mode and Telephone Group - To select the dial mode and a telephone group in the current system, press FCN PHONE. If there is more than one group programmed for telephone calls in the current system, the first high numbered telephone group is selected. If there is no telephone group or a conventional system is selected, “NO PHONE” is displayed and an error tone sounds.Selecting Dial Mode Without Changing Selected Group - To select the dial mode without changing the currently selected group, press FCN DIAL. This method should be used when placing auxiliary calls because the auxiliary call group and not the telephone group must be selected.The dial mode is indicated when the handset portion of the tele-phone icon is displayed. The base portion is displayed when a tele-phone group is selected, and “UID” is displayed when an auxiliary call group is selected.

DIAL MODE39Dialing a NumberEnter the desired number by pressing the 0-9, , and keys. Other dialing functions are as follows:•Only the last 8 digits dialed are displayed. To momentarily display the upper 8 digits, press FCN .•To erase the last digit, press the CLR key (hold it down to repeat). To erase the entire number, press FCN CLR.•To enter a pause, press FCN (each pause equals one character).Sending the NumberTo automatically access the radio system and send the number in the display, press FCN SND. The keypad remains active while in a conversa-tion to allow additional numbers to be dialed. Simply press the PTT switch and dial the number. The number in the display does not change when a number is dialed in this manner. If you want to save the number in the display (see following information), make sure you do so before the dial mode is exited.Storing Numbers in MemoryUp to ten 16-digit numbers can be stored in memory and later recalled. Proceed as follows to store a number:1. Enter the number as described in the preceding “Dialing a Number” section.2. To store the number, press FCN RCL and the memory location from 0-9. 3. If there is already a number in the selected location, it is replaced by the new number. To clear a memory location, simply store a blank display.#

DIAL MODE40NOTE: The character is stored and sent normally (no pause occurs), and the character should not be stored because it may terminate the call when it is sent.Recalling Numbers From MemoryFrom Specific Location - FCN RCL 0-9 (location number)Stored in Next Location - RCL (hold down to repeat). If a number is already displayed, the number in the next higher location is indicated; if display is blank, the number in location 1 is indicated first.Last Number Dialed by Recalling from Memory - FCN RCL Last Number Dialed - FCN RCL Exiting Dial ModeWithout Sending Call Termination Characters - To exit the dial mode without sending the call termination characters, press FCN DIAL.Sending Call Termination Characters - To exit the dial mode and send the characters which automatically terminate the call, press FCN PHONE. Terminating a call in this manner prevents any additional billing for the time required to automatically detect the end of a call.Placing Calls Without Selecting Dial ModeTelephone and Auxiliary calls can also be placed without selecting the dial mode by using the procedure which follows:1. Access the radio system by briefly pressing the PTT switch. 2. When a dial tone is heard, dial the desired number while pressing the PTT switch. If too much time elapses between digits, the call is auto-matically terminated. NOTE: When receiving telephone or auxiliary calls, the selection of the dial mode is optional because it does not enhance operation.#

SYSTEM AND GROUP SCANNING41SYSTEM AND GROUP SCANNINGGeneralIntroductionThe scan feature monitors, in sequence, the systems and/or groups in the scan list. When a message is detected that the 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). System and group scanning or group scanning only may be used (see next page), and the operation of each type is as follows. Refer to page 23 for more information on systems and groups.System Scanning - Detects calls on all systems in the system scan list. If system scanning is not used, calls are detected on only the currently selected system. Group Scanning - Detects calls on all groups in the group scan list. These groups are from the selected system and also from scanned systems if system scanning. If group scanning is not used, calls are detected on only the selected group. In addition, calls may be detected on higher priority LTR-Net and LTR groups (see “Priority Calls” on page 46). Scan On-OffSystem and/or group scanning are turned on and off by pressing FCN SCAN. When either type of scanning is enabled, is indicated in the display (see following illustration). Then when group scanning is actually occurring, dashes are displayed instead of a group number (if the numeric display mode described on page 20 is selected). Group scanning is not indicated if the alpha display mode is selected, and system scanning is never indicated. The monitor mode must be disabled for scanning to occur (see page 50).

SYSTEM AND GROUP SCANNING42Scan TypesThe type of scanning selected is determined by the menu mode SCN TYPE parameter (see page 36). If it is not selectable, the scan type is fixed by system operator programming. The available scan types are as follows. SYSTEMS - Both system and groupGROUPS - Group scanning onlyOFF - Both types disabled (scanning not selectable)If the scan on-off key (FCN SCAN) is disabled, the selected mode is always enabled. If both this key and the SCN TYPE menu parameter are disabled, the scan mode and type are fixed by programming. The selected system and group can be changed while scanning using the SYS and GRP keys in the normal manner. Scanning resumes shortly after the change is made. When a call is received in the scan mode, the display changes to the system and group of the call. Programming determines if this change is temporary or permanent, and if a response occurs on the system/group of the call or the selected system/group. Refer to “Transmitting In The Scan Mode” on page 45 for more information. GSSystem Scan List Group Scan ListSystem or GroupScanning SelectedGroupScanning Occurring

SYSTEM AND GROUP SCANNING43LTR-Net Mode ScanningWhen system scanning with an LTR-Net system selected and roaming disabled, only the LTR-Net systems in the scan list that access the site of the selected system are scanned (any LTR and conventional systems are not scanned). If roaming is enabled, registration on other sites occurs normally and scanning of LTR-Net systems occurs as just described. However, if the current LTR-Net site is lost and no other LTR-Net site can be located, the LTR and conventional systems in the scan list are also scanned. Searching for an LTR-Net site continues and if one is again detected, registration on that site occurs and the LTR and conventional systems are no longer scanned. This operation can provide uninterrupted operation in areas which have not been converted to LTR-Net operation.LTR and Conventional Mode ScanningWhen an LTR or conventional system is selected with system scan-ning enabled and roaming disabled, scanning is sequential through only the LTR and conventional systems in the scan list (LTR-Net systems are not scanned). If roaming is enabled, all three system types or only LTR-Net systems may be scanned as described in the preceding LTR-Net description. Scan List ProgrammingGeneralNOTE: The selected (displayed) system and group are always scanned even if they have been deleted from the scan list. The scan list status of the displayed system is changed by pressing FCN S.A/D, and the status of the displayed group is changed by pressing FCN G.A/D. The displayed system is in the scan list and scanned normally when is displayed, and the displayed group is scanned when is displayed (see preceding illustration). Deleting a system only temporarily deletes the groups associated with that system because when

SYSTEM AND GROUP SCANNING44a system is added back into the scan list, the original group scan list is again active. Systems and groups can be deleted from the scan list in the normal manner while listening to a message on the system or group by simply pressing the S.A/D or G.A/D key. Scanning resumes shortly after the system or group is deleted. The S.A/D and/or G.A/D functions can also be disabled by programming. The scan list programming function performed by that switch is then not available.Saving Scan ListIf the menu mode SCN SAVE parameter is available (see page 36), you can select if scan list changes are saved. If “On” is selected, changes are saved as they are made and the scan list does not change when power is turned off. Conversely, if “Off” is selected, they are not saved and the default status of all systems and groups is reselected when power is turned on. If the menu SCN SAVE parameter is not selectable, the scan list save mode is fixed in one of these states.Scan Delay and Continue TimersWhen a message is received or transmitted while scanning, there is a short delay before scanning resumes. The delay after receiving a call prevents another message from being received before a response can be made. Likewise, the delay after transmitting a call ensures that you hear a response to your call instead of another message occurring on some other system or group. Note that scanning does not resume if it has been disabled, such as by selecting the monitor mode.There is also a scan continue timer that may be programmed. This timer controls the maximum time that a call is received before scanning resumes. Times up to 60 seconds can be programmed. This prevents scan-ning from being delayed for long periods by lengthy calls. If the menu SCN CONT parameter is selectable (see page 36), this feature can be turned on and off.

SYSTEM AND GROUP SCANNING45Transmitting In The Scan ModeGeneralWhen messages are received while scanning, programming deter-mines if the selected system/group does not change, changes permanently to the new system/group, or changes temporarily. This in turn affects the system/group on which responses occur. The display always indicates the system/group on which a call is received, but this may not be the system/group on which a response occurs. The three programmable configura-tions operate as follows:Last Selected - Transmissions always occur on the system/group that was selected manually by the SYS and GRP keys or automatically by roaming. Therefore, to respond to a message that is not on the selected system/group, the selected system/group must be changed using one of these methods:•Select the system/group of the call manually using the SYS and GRP keys.•Before scanning resumes, exit the scan mode by pressing FCN SCAN. The system/group of the call then becomes the selected system/group and it is not necessary to change it manually.Last Received - The selected system/group changes to the system/group of a call. Therefore, you can always respond to a call without having to manually change the system/group. To return to the previously selected system/group, it must be manually selected using the SYS and GRP keys.Temporary Last Received - The system/group changes to the system/group of a call for only the duration of the scan delay period (see page 44.) Then when the delay expires and scanning resumes (if it is not disabled), the selected system/group is again displayed. Therefore, you can respond to a call without changing the selected system/group as long as you do so before scanning resumes.

LTR-NET AND LTR FEATURES46LTR-NET AND LTR FEATURESTransmit InhibitThe Transmit Inhibit feature prevents the transmitter from keying if the mobile you are calling is busy with another call. When the transmitter is disabled by this feature, the intercept tone sounds and “TX INHIB” is displayed (see following illustration). To make another call attempt, the PTT switch must be released and pressed again. However, you may want to wait a few seconds before making another attempt because a timer must time out before another attempt will be successful. A similar Transmit Disable On Busy feature is available on conventional systems (see page 51).Priority CallsEach LTR-Net and LTR group is programmed with a receive priority number. If a call is detected on a group in the group scan list that has a higher priority than the selected group, it is received (even if scanning is not enabled). If another call is in progress when the higher priority call is detected, the current call is immediately dropped. Some groups, such as those used to make telephone calls, may be programmed as not interrupt-ible to prevent other calls from interrupting a call in progress. The system/group of the priority call is displayed while it is received. The programming described on page 45 determines if the change is temporary or permanent and if a response occurs on the last selected or received system/group.

LTR-NET FEATURES47LTR-NET FEATURESNOTE: Other LTR-Net features are described starting on page 46.LTR-Net Standard Calls Standard group calls are between two mobiles or between a mobile and a control station. To place these calls in the LTR-Net or LTR mode, simply select the desired group and press the PTT switch (no number is dialed) as described starting on page 29.LTR-Net Special CallsThe LTR-Net Special calls are as follows:Telephone Calls - These calls allow you to place and receive telephone calls using your transceiver. They are described starting on page 31.Auxiliary Calls - As shown in the preceding illustration, these calls include Unique ID and Directed Group calls. Unique ID calls are to specific mobiles, and Directed Group calls are to specific talk groups. Refer to page 33 for information on placing and receiving Auxiliary calls.Busy QueuingIf system resources are not available when placing special calls, queuing may be provided by the radio system. Standard group calls are not queued. When a call is placed in a queue, a voice message informs you that this has occurred. Then when resources become available, the call is automatically placed and the normal ringing or other tones are heard if applicable. If the call cannot be placed in the allotted time, it is terminated and another message informs you that this has occurred.SpecialTelephoneAuxiliaryDirected GroupUnique ID

LTR-NET FEATURES48RoamingLTR-Net radio localities (sites) can be linked together to provide wide area coverage. Calls can then be automatically routed to your current location as you travel from locality to locality. Both standard group and special calls may be routed in this manner. If your transceiver is programmed for roaming, this feature is utilized as follows:1. Enable roaming using the Roam option switch or ROAMING menu parameter (see page 35) if available. When roaming is enabled and disabled by the option switch, “ROAM ON” and “ROAM OFF” are momentarily displayed. If neither the menu parameter nor option switch is available, roaming is fixed in the on or off mode by program-ming.2. If scanning is disabled, an LTR-Net system must be selected. If system scanning is enabled, any system can be selected if the LTR-Net systems are in the system scan list (see page 43).When roaming is enabled as just described and the signal from the current locality becomes weak, the transceiver automatically begins searching for another locality. While searching is occurring, “LCL SRCH” is displayed as shown below. Then when a new locality is located, registration occurs and “LCL SRCH” is no longer displayed. The displayed system is then the next LTR-Net system programmed with a different locality that could be accessed, and the displayed group is usually the group that was displayed before roaming occurred.

LTR FEATURES49LTR FEATURESNOTE: Other LTR features are described starting on page 46.Standard Group CallsStandard group calls are between two mobiles or between a mobile and a control station. To place these calls in the LTR or LTR-Net mode, simply select the desired group and press the PTT switch (no number is dialed). The procedure for placing and receiving these calls is described starting on page 29.Telephone CallsTelephone calls allow you to place and receive calls over the public telephone system using your transceiver. LTR and LTR-Net telephone calls are described starting on page 31.CONVENTIONAL FEATURESSquelch AdjustThis function sets the squelch level used for conventional calls. Since the squelch level for LTR-Net and LTR calls is preset and cannot be changed, this adjustment needs to be made only if you make conventional calls (refer to page 23 for more information on operating modes). Proceed as follows:1. Select a conventional system and a group that is not busy. If the selected channel is programmed for Call Guard squelch, press the Monitor option switch to enable monitoring (see page 50).2. Press FCN SQL to select the squelch adjust mode. The currently selected squelch level is then indicated by “SQ xxx” in the display.

CONVENTIONAL FEATURES503. Press the key until receiver noise is heard and then press until the noise just mutes. To decrease or increase the selected level in steps of 10 (or select the minimum or maximum level if this is not posssible), press FCN or FCN , respectively.NOTE: Slight readjustment may be required if weak messages are not heard or unsquelching occurs when no messages are present.4. To exit this mode, press the FCN SQL again. Exiting also occurs auto-matically after 2 seconds of no activity. 5. If both narrow and wide band channels are used, perform this adjust-ment for each type because separate settings are maintained.Monitoring Before TransmittingGeneralRegulations require that conventional channels (groups) be moni-tored before transmitting to make sure that they are not being used by someone else. If you were to transmit when someone else is talking, you would probably disrupt their conversation. Proceed as follows to auto-matically or manually monitor conventional channels. In the LTR-Net and LTR modes, monitoring is always performed automatically. Automatic Channel MonitoringIf the selected group is programmed with the Transmit Disable On Busy feature (see page 51), monitoring is performed automatically. If not, it must be monitored manually using one of the methods which follow.Busy IndicatorWith scanning disabled and the squelch properly adjusted (see page 49), note if “BUSY” is indicated in the display (see following illus-tration). If it is, a signal is being detected on the selected group (channel) and you should not transmit a message until it turns off.

CONVENTIONAL FEATURES51Monitor ModeThere 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. This mode is enabled by pressing the Monitor option switch (see page 35), and is indicated by in the display as shown in the following illustration. While this switch is pressed, both Call Guard squelch (see page 52) and scanning are disabled so that any activity on the group is heard.A conventional system must be selected to enable monitoring. If the Monitor option switch is pressed with an LTR-Net or LTR system selected, scanning halts but monitoring is not enabled. Transmit Disable On BusyThe Transmit Disable On Busy feature automatically disables the transmitter if the selected group (channel) is busy and it has not been monitored when the PTT switch is pressed. When the transmitter is disabled by this feature, the busy tone sounds briefly and “DSBL BSY” is indicated in the display as follows: While the PTT switch is pressed, the receiver is enabled so that activity on the channel can be monitored. The PTT switch must be BUSYBusyIndicatorMonitor ModeSelected

CONVENTIONAL FEATURES52released and then pressed again to make another call attempt. Occasion-ally, a busy condition may be detected even though no one is talking. To key the transmitter in this case, release the PTT switch and then immedi-ately press it again. There is also a programmable option with this feature to allow trans-mitting with a busy channel if the correct Call Guard signal is detected. The Transmit Disable On Busy feature is enabled or disabled on each conventional group by system operator programming. If this feature is disabled or if monitoring has been performed by taking the microphone off-hook, the transmitter keys even if the group is busy.Talk-AroundNormally, all transmissions go through a repeater which usually increases range because the repeater transmits at a higher power level and has a higher antenna. However, this means that if you are out of radio range of the repeater, you cannot talk to anyone even if the mobile you are calling is only a short distance away. To allow communication if this occurs, talk-around groups can be programmed which enable direct mobile-to-mobile communication without going through a repeater.Talk-around is then automatically enabled by selecting one of these groups. There is no special talk-around option switch or indicator. However, the group alpha tag on the lower line of the display may be used to indicate groups programmed for this feature. Talk-around is not available on LTR-Net and LTR systems.Call Guard SquelchThe 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. It is transmitted with the voice signal but is not heard because it is in the subaudible range and attenuated by a filter. Call Guard squelch can be programmed on each conventional group. LTR-Net and LTR operation uses ID codes to perform a similar function.

MISCELLANEOUS53MISCELLANEOUSSupervisory TonesThe following tones are heard at various times when operating this transceiver. Some or all of these tones can be disabled by the TONES menu parameter or programming (see “Tone Select” on page 29).Busy Tone This tone is similar to the standard telephone busy tone, and it indi-cates that the radio system is currently busy. The display also indicates “BUSY” while this tone is sounding. Repeated access attempts are made while the PTT switch pressed with this tone sounding. Therefore, it is not necessary to release the PTT switch to access the system. This tone sounds only with LTR-Net and LTR calls.Intercept Tone This is a siren-like tone (alternating high and low tones) which indi-cates the following no access and error conditions: •No Access - If this tone sounds shortly after pressing the PTT switch and “NO ACCES” is displayed, the radio system could not be accessed, perhaps because of an out-of-range condition (see “Opera-tion At Extended Range” on page 60). Once this tone sounds, no more access attempts are made until the PTT switch is released and then pressed again. This condition is indicated only with LTR-Net and LTR calls.•Time-Out Timer - If this tone sounds after the transmitter has been keyed for an extended period and “TIMEOUT” is displayed, the transmitter has been disabled by the Time-Out Timer feature (see page 28). •Transmit Inhibit - If this tone sounds as soon as the PTT switch is pressed with an LTR-Net or LTR system selected and “TX INHIB”

MISCELLANEOUS54is displayed, the transmitter has been disabled by the Transmit Inhibit feature (see page 46).•Receive-Only Group - If this tone sounds as soon as the push-to-talk switch is pressed and “TX DISBL” is displayed, the group is receive-only (see page 28). Proceed (Clear-To-Talk) Tone - This is a short single or double tone which sounds after the push-to-talk switch is pressed to indicate when talking can begin (see page 27).Key Press Tone - This is a short tone that indicates when an option switch is pressed. Wrap-Around Tone - This is a two-pitch tone that indicates that the highest or lowest channel was displayed and that wrap-around has occurred.Error Tone - This is a two-pitch tone that indicates that an error condition has occurred.LTR-Net Special Call TonesThe following tones are generated by the LTR-Net equipment and are heard when making a telephone, unique ID, or directed group special call on an LTR-Net system.Confirmation Tone - This is a short tone that sounds when the number just dialed has been accepted by the system.Call Proceed Tone - With LTR-Net directed group calls (see page 34), ringing does not occur after the number is dialed. Instead, another short tone sounds after the confirmation tone to indicate that the audio path is complete and speaking can begin.End Call Tone - Three beeps which indicate that the end of the call has been detected by the system.

MISCELLANEOUS55Proceed Dialing Tone - When placing a landside-to-mobile telephone call (see page 33), the landside caller may enter a special number which specifies the mobile being called. This tone indicates when that number should be dialed.LTR Telephone Call TonesThe following tones are generated by LTR interconnect equipment and are heard when making LTR telephone calls. Reorder Tone - Three beeps which indicate that the call has been termi-nated by the system. Return Time Warning Tone - Two beeps which warn that you have not transmitted for an extended period. If you do not transmit within 5 seconds, the call is automatically terminated by the system. The time between transmissions is one of the parameters used by the system to detect the end of a call when the # character is not sent. Conversation Time-Out Tone - Calls are limited to a certain length by the system. Thirty seconds before this time is reached, a “tick” begins sounding each second. When the 30-second time expires, the call is auto-matically terminated by the system.Turn-Around Tone - This is a single beep which may be used to indicate to the landside party when to respond to your transmission. It sounds when you release the PTT switch, and you may partially hear this tone.Proceed Tone - This tone consists of two beeps and it tells the landside caller when to enter the five-digit number specifying the mobile being called. Dialing of this number must be started within 5 sec. of hearing this tone, and a tone-type telephone must be used.Display MessagesThe following messages appear in the display to indicate various operating modes and error conditions.

MISCELLANEOUS56BUSY - Indicates that the LTR-Net or LTR radio system is currently busy (see “Busy Tone” on page 53).CALL SVC - Indicates that the transceiver is inoperative. Contact your system operator for service.DSBL BSY - Indicates that the transmitter is disabled by the conven-tional Transmit Disable On Busy feature (see page 51). It also indicates that the transmitter was keyed while receiving an LTR-Net or LTR call. FCN - Indicates that the function select mode is selected by the FCN option switch (see page 15).LCL SRCH - Indicates that the transceiver is currently searching for a new locality (site) on which to register (see page 48).Model - The last seven digits of the transceiver part number are indicated very briefly in the display when transceiver power is turned on. This number indicates such things as frequency band, power output, and tier of the transceiver. The eighth digit is reserved and always “0”.NO ACCES - Indicates that the radio system could not be accessed, perhaps because of an out-of-range condition. Refer to “Operation At Extended Range” on page 60 for more information.NO PHONE - Indicates that there is no telephone group programmed in the current system when the dial mode is selected by pressing FCN PHONE (see page 38).NOT AUTH - Indicates that an attempt was made to register on a site where service was not authorized (see page 48).NOT CONV - Indicates that an attempt was made to enable a conven-tional mode feature on an LTR-Net or LTR system. NOT LNET - Indicates that an attempt was made to enable an LTR-Net mode feature on an LTR or conventional system.

MISCELLANEOUS57OUT-LOCK - Indicates that the synthesizer is unlocked. Refer to “Transceiver Service” on page 60 for more information. PROG ERR - Indicates an EEPROM read error. Refer to “Transceiver Service” on page 60 for more information.SLEEPING - Indicates that the transceiver has been temporarily disabled by the system operator. It will be automatically enabled again when oper-ation can be resumed.SQUELCH - Indicates that the conventional squelch adjust mode is selected (see page 49).TIMEOUT - Indicates that the transmitter has been disabled by the Time-Out Timer (see page 28). TX DISBL - Indicates that the transmitter has been disabled because the selected group is receive-only (see page 28).TX INHIB - Indicates that the transmitter has been disabled by the Transmit Inhibit feature (see page 46).Menu Mode MessagesThe following messages are displayed in the menu mode that is described starting on page 35.

The battery pack contains nickel metal-hydride (NiMH) cells which must be disposed of in accordance with local regulations. Do not short the termi-nals because the battery may become very hot.Battery LifeWith proper care, the nickel metal-hydride (NiMH) battery pack used by this transceiver should provide excellent service. When the pack no longer holds a charge or provides only a very short operating time, it must be replaced with a new unit.

MISCELLANEOUS59Typical operating time before recharging is required is 8 hours. This assumes that the transceiver is transmitting at high power 5% of the time, receiving and producing audio 5% of the time, and in the standby mode (receive with audio muted) 90% of the time. If the low-power mode is selected or different times are spent in these modes, operating time varies accordingly. The charge of the battery and ambient temperature also affect operating time.NOTE: Be sure to turn transceiver power off before removing the battery pack. Failure to do so may result in current settings not being saved in memory.RechargingRecharging is required when the icon is displayed as described on page 23. The pack can be recharged while still on the trans-ceiver or it can be charged separately. To remove the battery pack from the transceiver, press the spring-loaded release button on the bottom and slide the battery off. A new battery pack must be charged before use.Battery CareOne cause of shortened battery life is repeated deep discharge. Therefore, it is recommended that the battery be recharged as soon as practical after the low-battery indication appears (see preceding informa-tion). Do not continue using the transceiver until the battery is completely discharged. Another cause of reduced battery life is operation at tempera-ture extremes. It is also good practice not to regularly leave a pack in the charger for extended periods after it is completely charged.It is possible that the pack could develop a characteristic called “memory” although these packs are designed to minimize that problem. When a pack has this problem, it acts as if it is totally discharged even though it has greater capacity. This can be caused by discharging a pack only slightly before recharging, charging at too high a temperature, or extended storage. If a pack develops this problem, it can usually be corrected by performing three discharge/charge cycles.

MISCELLANEOUS60Speaking Into MicrophoneFor best results, hold the speaker grille about 1-2 inches from you mouth and speak at a normal conversational level. Do not shout since it distorts you 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. Even though you can hear messages, you may still be out of radio range. The reason for this is that the signal being received is normally transmitted by a repeater which usually has a much higher power level than is produced by your transmitter. Communication may be improved by moving to higher ground or away from shielding objects such as tall buildings or hills.LicensingA government license is usually required to operate this transceiver on the air. Your system operator will normally handle the licensing requirements.Transceiver ServiceIf your transceiver is not operating properly, “OUT-LOCK”, “PROG ERR”, “SLEEPING”, or “CALL SVC” may be displayed. It may be possible to clear the first two conditions by turning power off and then on again to reset the control logic. Also make sure that the controls are prop-erly set and that the battery is fully charged. If the transceiver still does not operate properly, return it to your system operator for service.

INDEX61The “SLEEPING” message indicates the transceiver is temporarily disabled as described on page 57. If the CALL SVC message is displayed, the transceiver must always be returned to your system oper-ator 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.INDEXAAccessory Connector 12Alpha Tag Display Mode 21Alphanumeric Display 13Antenna Care 4Antenna Jack 12Auxiliary Call 47Placing 33Receiving 35BBacklight 20Battery Pack 58Battery Release Button 12Busy Queuing 47Busy Tone 53CCall Guard Squelch 52Call Indicator 14, 25Clear-to-Talk Tone 27CLR Key 16ControlsOn-Off/Volume 11Option Switch 12PTT Switch 12Top Panel 11Conventional Mode 24Conventional Mode Scanning 43DDIAL Key 17Dial Mode 38Exiting 40Selecting 38Dialing a Number 39Directed Group Call 33Directed Group Calls 47Disabling Keypad 22Display 13Display Messages 55Display ModeAlpha Tag 21Numeric 21Display Modes 20EEmergency Switch 26FFCC Rules 2FCN Key 15FeaturesConventional 10General 10LTR 10LTR- N et 10Front Panel Keys 15
