BASIC OPERATION Low Battery Indication When 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.
BASIC OPERATION LTR-Net and LTR Operation The 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.
GENERAL FEATURES GENERAL FEATURES Bank Select A 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.
GENERAL FEATURES Emergency Switch If 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 transmitted 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.
GENERAL FEATURES Home System/Group Select To 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.

Option Select The Auxiliary option switch or OPTION menu parameter can be used to control an accessory that may have been installed by your system operator.
GENERAL FEATURES sound 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.
STANDARD GROUP CALLS One use of the time-out timer feature is to prevent a repeater from being kept busy for an extended period by an accidentally keyed transmitter. It can also prevent possible damage to the transmitter caused by transmitting for an excessively long period. Tone Select If 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.
STANDARD GROUP CALLS 4. 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.
TELEPHONE CALLS Receiving a Standard Group Call 1. Select or scan the system and group programmed for the call you want to receive (see page 41 for scan information). 2.

DIAL MODE DIAL MODE Introduction When 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.
DIAL MODE Dialing a Number Enter the desired number by pressing the 0-9, # , and dialing functions are as follows: keys. Other • 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).
DIAL MODE NOTE: 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 Memory From 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.
SYSTEM AND GROUP SCANNING SYSTEM AND GROUP SCANNING General Introduction The 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.
SYSTEM AND GROUP SCANNING System Scan List S System or Group Scanning Selected Group Scan List G Group Scanning Occurring Scan Types The 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.
SYSTEM AND GROUP SCANNING LTR-Net Mode Scanning When 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.
SYSTEM AND GROUP SCANNING a 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.
SYSTEM AND GROUP SCANNING Transmitting In The Scan Mode General When messages are received while scanning, programming determines 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.
LTR-NET AND LTR FEATURES LTR-NET AND LTR FEATURES Transmit Inhibit The 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.
LTR-NET FEATURES LTR-NET FEATURES NOTE: 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 FEATURES Roaming LTR-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.
LTR FEATURES LTR FEATURES NOTE: Other LTR features are described starting on page 46. Standard Group Calls Standard 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.
CONVENTIONAL FEATURES 3. 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 automatically after 2 seconds of no activity. 5.
CONVENTIONAL FEATURES Busy Indicator BUSY 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. 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.
CONVENTIONAL FEATURES released and then pressed again to make another call attempt. Occasionally, 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 immediately press it again. There is also a programmable option with this feature to allow transmitting with a busy channel if the correct Call Guard signal is detected.
MISCELLANEOUS MISCELLANEOUS Supervisory Tones The 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 indicates that the radio system is currently busy. The display also indicates “BUSY” while this tone is sounding.
MISCELLANEOUS is 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 receiveonly (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).
MISCELLANEOUS Proceed 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 Tones The 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 terminated by the system.
MISCELLANEOUS BUSY - 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 conventional Transmit Disable On Busy feature (see page 51). It also indicates that the transmitter was keyed while receiving an LTR-Net or LTR call.
MISCELLANEOUS OUT-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 operation can be resumed. SQUELCH - Indicates that the conventional squelch adjust mode is selected (see page 49).
MISCELLANEOUS ROAMING - LTR-Net roaming on-off • ON or OFF SCN CONT - Scan continue on-off • ON or OFF SCN SAVE - Scan list save • ON = save, OFF = not saved SCN TYPE - Selects type of scanning • SYSTEM - Both system and group • GROUPS - Group scanning only • OFF - All scanning disabled STEALTH - Stealth mode select • ON or OFF TONES - Beep tones select • SILENT - All tones disabled • KEYS - Only Select switch and key press tones sound • ALERTS - All tones sound except preceding Key Beeps sound • ALL - All
MISCELLANEOUS Typical 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.
MISCELLANEOUS Speaking Into Microphone For 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.
INDEX The “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 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.
