3RF EXPOSURE INFORMATIONRF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION, AND OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTSBEFORE USING YOUR PORTABLE 2-WAY RADIO, READ THIS IMPORTANT RF ENERGY AWARENESS AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE WITH THE FCC’S RF EXPOSURE GUIDELINES.NOTICE: This radio is intended for use in occupa-tional/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC limits. This radio device is NOT authorized for general population, consumer, or any other use.This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide commu-nications between two or more users over a distance. It uses radio frequency (RF) energy or radio waves to send and receive calls. RF energy is one form of elec-tromagnetic energy. Other forms include, but are not limited to, electric power, sunlight and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which when used improperly can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. Experts in science, engineering, medicine, health and industry work with organizations to develop stan-dards for exposure to RF energy. These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection. All 2-way radios marketed in North America are designed, manufactured and tested to ensure they meet government established RF expo-sure levels. In addition, manufacturers also recom-mend specific operating instructions to users of 2-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following websites for more information on what RF energy exposure is and how to control your expo-sure to assure compliance with established RF expo-sure limits. •http://www.fcc.gov/oet/rfsafety/rf-faqs.html•http://www.osha.gov/SLTC/radiofrequencyradiation/index.html FEDERAL COMMUNICATIONS COMMISSION REGULATIONSThe FCC rules require manufacturers to comply with the FCC RF energy exposure limits for portable 2-way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupa-tional requirements. Exposure awareness can be facili-tated by the use of a product label directing users to specific user awareness information. Your EFJohnson 2-way radio has a RF exposure product label. Also, your EFJohnson user manual, or product manual, or separate safety booklet includes information and oper-ating instructions required to control your RF exposure and to satisfy compliance requirements. COMPLIANCE WITH RF EXPOSURE STANDARDSYour EFJohnson 2-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) for human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP expo-sure limits for occupational/controlled RF exposure environment at operating duty factors of up to 50% transmitting and is authorized by the FCC for occupa-tional use only. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Note: The approved batteries supplied with this radio are rated for a 5-5-90 duty factor (5% talk-5% listen - 90% standby), even though this radio complies with the FCC occupational RF exposure limits and may operate at duty factors of up to 50% talk.

4RF EXPOSURE INFORMATIONYour EFJohnson 2-way radio complies with the following RF energy exposure standards and guide-lines:•United States Federal Communications Commis-sion, Code of Federal Regulations; 47 CFR §§ 1.1307, 1.1310, 2.1091 and 2.1093 •American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992 •Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES AND OPERATING INSTRUCTIONSTo control your exposure and ensure compliance with the occupational/controlled environment expo-sure limits always adhere to the following procedures.Guidelines:•Do not remove the RF Exposure Label from the device. •User awareness instructions should accompany device when transferred to other users. •Do not use this device if the operational require-ments described herein are not met. Operating Instructions: •Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the time, or less, is important because this radio generates measurable RF energy exposure only when transmitting (in terms of measuring for standards compliance).•Hold the radio in a vertical position in front of face with the microphone (and the other parts of the radio, including the antenna) at least one inch (2.5 am) away from the nose. Keeping the radio at the proper distance is important because RF exposures decrease with distance from the antenna. Antenna should be kept away from eyes. •When worn on the body, always place the radio in an EFJohnson approved clip, holder, holster, case, or body harness for this product. Using approved body-worn accessories is important because the use of EFJohnson or other manufacturer’s non-approved accessories may result in exposure levels, which exceed the FCC’s occupational/controlled environment RF exposure limits. •If you are not using a body-worn accessory and are not using the radio in the intended use position in front of the face, then ensure the antenna and the radio are kept at least 2.5 cm (one inch) from the body when transmitting. Keeping the radio at the proper distance is important because RF exposures decrease with increasing distance from the antenna. •Use only EFJohnson approved supplied or replace-ment antennas, batteries, and accessories. Use of non-EFJohnson approved antennas, batteries, and accessories may exceed the FCC RF exposure guidelines. •For a list of EFJohnson approved accessories, see the service manual or marketing accessory lists or contact the EFJohnson Company CONTACT INFORMATIONToll-Free: 800-328-3911FAX: 507-835-6969E-Mail: customerservice@efjohnson.com You can also e-mail a person directly if you know their first initial/last name (example: jsmith@efjohnson.com).You may also contact the Customer Service Department by mail.

The default icons are as follows: - When the scan or the scan list edit mode is enabled, indicates that the displayed channel is in the scan list and scanned normally (see Section 4.8). - When the scan or the scan list edit mode is enabled, indicates that the displayed channel is a priority channel. If dual priority is used, indicates that it is a second priority channel. - Low battery indication (see Section 3.4). - Voice encryption is enabled (see Section 8.1). - Standard or radio wide scanning is enabled (see Section 4.8). - Repeater talk-around is enabled (see Section 5.8). - Monitor mode is enabled by the Monitor option switch or menu parameter (see Section 5.3). - Keypad programming or another mode is enabled which allows the user to edit radio parameters. - A SMARTNET/SmartZone interconnect* (telephone) call is in progress (see Section 6.6). - A Project 25 or SMARTNET/SmartZone private (unit-to-unit) call is in progress.Option SwitchesPTT SwitchBattery PackAccessoryConnector123IconAreaTextArea2* Telephone calling is currently not available.

13GENERAL OPERATIONSECTION 3 GENERAL OPERATION3.1 TURNING POWER ON AND SETTING VOLUME3.1.1 POWER UPPower is turned on and off by the top panel On-Off/Volume switch. When power is initially turned on, the following events occur:•The software version number is displayed.•A self test is performed.•The currently selected zone is displayed.•If a conventional P25 channel is selected, the Individual ID of the radio is displayed.•If a SMARTNET/SmartZone or P25 Trunked channel is selected, the Unit ID of the radio is displayed. •A tone sounds (if tones are enabled)•The selected channel alias is displayed continuously when power-up is complete. Programming determines if the transceiver powers up on the last selected zone or the pre-programmed home zone. Refer to Section 3.3 for information on the channel that is selected. The minimum volume level may be set by programming. This can prevent missed messages resulting from inad-vertently turning the volume to an inaudible level.3.1.2 STANDARD AND SOFT POWER DOWNTo turn power off, rotate the On-Off/Volume control counterclockwise until a click occurs. Power may remain on for an instant after turn-off occurs.A soft power down feature* can be programmed to prevent radio power from being turned off by acci-dentally turning the on-off/volume control. Any side button can be programmed for this function (in addi-tion to the normal function). Then for power to turn off, this button must be pressed during or after power is turned off in the normal manner using the knob. When this feature is programmed, turning the on-off/volume knob to off has no affect.3.1.3 SETTING VOLUME LEVELThe volume level is adjusted by the top panel volume control knob or by option buttons programmed for the Up/Down volume function**. When the buttons are used, the volume control function of the knob is disabled (it is still used to switch power). Volume buttons may be used instead of the knob, for example, if accidental turning of the volume knob occurs. When the volume control buttons are used, the number of steps (ticks) the volume changes from minimum to maximum is programmable for 1-50. For example, if “20” is programmed, there are 20 adjust-ment steps from minimum to maximum volume. Only one volume control button can be programmed if desired and wrap-around then occurs after the maximum or minimum level is selected. The relative volume level can be determined by the position of the index on the volume knob or by a reference tone as follows:•If a key press tone is enabled, a short tone sounds when a key is pressed. •If a conventional channel is selected and the Monitor option switch or menu parameter is programmed, pressing that switch unsquelches the receiver and either voice or background noise is heard (see Section 5.3). If a SMARTNET/Smart-Zone or P25 Trunked channel is selected, the receiver cannot be manually unsquelched.3.2 POWER-UP PASSWORDThe power-up password feature prevents unau-thorized use of the transceiver by locking the keypad on power up until the proper password is entered. This feature is enabled or disabled by programming.When it is enabled, “ENTER PSWD” is briefly displayed when power is turned on. The eight-digit numeric password must be then be entered as follows. In addition, since the logic resets each time program-* This feature requires 51xx operating (Flash) software 1.9.0 or later and PCConfigure 1.20 or later. ** This feature requires 51xx operating (Flash) soft-ware 1.11.0 or later and PCConfigure 1.21 or later.

GENERAL OPERATION14ming data is read or written, it must be entered after performing those functions. If an incorrect password is entered, “INCORRECT” is displayed and it must be re-entered.DTMF Keypad Models - Enter the password using the 1-8 keys and then press the Enter (F2) key when finished. If a mistake is made, the last digit can be erased by pressing the F1 (Clear) key. Limited Keypad Models - Select the proper number for each position by pressing the Up/Down switch. When the proper number for a position is displayed, select it and move on to the next position by pressing the F2 (Enter) key. This password can be changed only by the programmer (see Section 4 of the 5100 Service Manual). It cannot be changed by the user. If it is lost, all programming must be erased to make the trans-ceiver operational again. This is done using the “EEPROM Erase” function of the PCTune program (see Section 6.3.3 of the 5100 Service Manual). This password is displayed by the programmer when data is read. However, data cannot be read (or written) when the transceiver is locked, so the lost password cannot be determined using the programmer. 3.3 ZONE AND CHANNEL SELECTThe selected zone and channel are selected and displayed as follows. For more information on zones and channels, refer to Section 3.8.5.Zone SelectThe front panel Up/Down switch changes and displays the current zone. When not in special modes such as the menu mode, pressing either the top or bottom part of this switch once displays the alias of the current zone. Then quickly pressing it again changes the selected zone up or down. The rotary A/B/C switch on the top panel can also be programmed for zone select (with Flash code 1.7.0 or later). The “A” posi-tion then selects Zone 1, “B” Zone 2, and “C” Zone 3 (if applicable).After the highest programmed zone is displayed, wrap-around to the lowest programmed zone occurs and vice versa. The selected zone is also displayed briefly on power up. If the selected zone alias needs to be displayed continuously, it must be programmed as part of the channel alias.Channel Select Channels are selected by the rotary 16-position switch on the top panel. The alias (identification) for the selected channel/group is displayed continuously during normal operation.When an unprogrammed channel is selected, “UNPROGRAMD” is displayed and a tone sounds (if tones are enabled). When conventional channels are selected and the Display Information option key or menu parameter is programmed, either the channel frequency or alias can be displayed (see Section 5.9).The channel selector knob can also be disabled by programming. Channels must then be directly selected as described next (if applicable). This knob may be disabled when direct selection is used to prevent confusion because it then may not correctly indicate the selected channel.Direct Zone/Channel Selection*The direct Channel Select feature is available if the Channel Select option switch or menu parameter is programmed. This feature allows channels to be directly selected using the DTMF keypad numeric keys (DTMF models only) or Up/Down switch (all models). For direct selection purposes, channels are numbered sequentially starting with the lowest zone. Each zone can be programmed with up to 16 channels, so Zone 1 channels are numbered 1-16, Zone 2 chan-nels 17-32, and so on as shown below. For example, Zone 1/Channel 16 is selected by Channel 16, and Zone 2/Channel 16 is selected by Channel 32.Proceed as follows to select channels using this mode:1. Enable the direct Channel Select mode by pressing the Channel Select option switch or selecting the “Chan Selct” menu parameter. The alias and sequential number of the current channel are alter-nately displayed.* This feature requires 51xx operating (Flash) software 1.5.0 or later and PCConfigure 1.17 or later.

GENERAL OPERATION152. Select the desired channel using the Up/Down keys or directly enter it using the 0-9 keys (if available). If using the 0-9 keys, the radio attempts to display the entered number after the 3rd digit is entered or approximately 2 seconds after the last key is pressed. 3. To exit the this mode and select the entered channel, press the Channel Select switch again or the F2 key. To exit without changing the channel, press the F1 key. This mode is also exited automatically without changing the channel after approximately 1 minute of no activity.NOTE: The Channel Select function should probably not be assigned to a number key because pressing that key to select a channel then exits the select mode. Other features of this mode are as follows:•When using the Up/Down keys, wrap-around to the lowest zone/channel occurs after the last channel in the highest programmed zone is displayed and vice versa. For example, if Zone 1/Channel 5 is the highest programmed channel, wraparound occurs after Zone 1/Channel 16 is displayed.•When an unprogrammed channel is displayed, the sequential channel number and “Unprogramd” are alternately displayed. •If an invalid channel number is entered using the 0-9 keys, or the F2 or Channel Select open switch is pressed with “Unprogrammed” displayed, an error tones sounds, “Invalid” is briefly displayed, and the displayed channel does not change.•The rotary Channel Select switch may not correctly indicate the selected channel after direct channel selection is used. However, if this switch is enabled by programming and rotated, it selects the channel it is indicating. For example, if the switch index is pointing to channel 3 and channel 15 of the current zone is being displayed, rotating it to channel 4 selects channel 4 of the current zone.•If the rotary Channel Select switch is enabled, the radio always powers up on the channel it is selecting. If it is disabled, the radio can be programmed to power-up on the last selected or home channel number of the last selected or home zone*. With the “Last Zone”/“Home Channel” configuration, the programmed home channel number of the last active zone is selected. If it is not programmed, “Unpro-grammd” is displayed. With earlier models, the last selected channel is displayed when powering up on the last selected zone, and channel 1 is displayed when powering up on the home zone.3.4 LOW BATTERY INDICATIONNOTE: If the transceiver contains encryption (hard-ware) keys, be sure to reattach a battery within approximately one minute to prevent the loss of these keys. A low-battery condition is indicated by the icon in the display. The battery should be recharged or replaced as soon after this indication appears. Once this indication appears, it stays on until power is cycled.The following additional low battery indications and conditions may be enabled by programming:•A chirp sounds once a minute in the standby and transmit modes.•A chirp sounds each time the PTT switch is pressed.•The top panel LED indicator flashes red every 30 seconds in the receive mode.•Low power is selected when transmitting. Zone Ch. Seq. Ch. No.11116 16211716 323133* This feature requires 51xx operating (Flash) software 1.9.0 or later and PCConfigure 1.20 or later.

GENERAL OPERATION16As indicated in the preceding “Note”, the trans-ceiver must be connected to a constant power source to preserve the encryption (hardware) keys in memory. To allow the battery to be changed without losing these keys, storage capacitors maintain the supply voltage to memory for approximately 1 minute without a battery attached. Therefore, when changing the battery of a transceiver that has these keys stored, be sure to reat-tach a battery within that time. Refer to Section 8.1.6 for more information on encryption keys.There is a battery saver feature that can be enabled by programming. This feature functions on trunked channels and Flash code 1.7.0 or later only, and it causes low transmit power to be selected when the receive signal strength (RSSI) indicates that the site is nearby. 3.5 BACKLIGHTThe backlight for the display and option keys can be programmed to automatically turn on when any key is pressed. It then automatically turns off after a programmed delay of 0-7.5 seconds so that battery drain is minimized. If the Backlight option switch or menu parameter is programmed, the user can manually turn the backlight on and off (it then stays on). If the Surveillance mode is programmed, the backlight is disabled (see Section 4.7).3.6 KEYPAD LOCKThe Keypad Lock feature temporarily disables the front panel keys to prevent accidental key presses. This feature is available if the Keypad Lock option switch is programmed.To lock the keypad, simply press the Keypad Lock option switch. Then to unlock the keypad again, press and hold this switch until a tone sounds or for approximately 1 second.With DTMF models, the DTMF keys can be totally disabled by programming. In addition, they can be selectively enabled or disabled on conventional analog channels. 3.7 SETTING SQUELCH This transceiver does not have a squelch control. The squelch level is preset during alignment. If the keypad programming feature is available (see Section 5.17), the squelch level can be changed by the user on each conventional analog channel. 3.8 TRANSCEIVER OPERATING MODES3.8.1 GENERALEach selectable channel can be programmed for the conventional (analog or Project 25 digital), SMARTNET/SmartZone, or Project 25 digital trunked operating mode. For example, Zone 1/Channel 1 could be a conventional channel, Zone 1/Channel 2 a SMARTNET channel, and so on. More information on these modes follows.3.8.2 CONVENTIONAL MODEThis is a non-trunked operating mode which accesses independent radio channels. There is no auto-matic access to several channels. Selecting a conven-tional channel selects a transmit and receive frequency and other channel parameters such as squelch control coding. Conventional channels can be either standard (analog) or Project 25 (digital). With digital operation, the DSP (Digital Signal Processor) converts the audio signal to digital data which is sent over the air as complex tones. Another difference is that analog chan-nels use Call Guard (CTCSS/DCS) squelch control and Project 25 channels use a NAC (Network Access Code) and talk group ID codes. With Project 25 operation, a NAC is transmitted and it must match the NAC programmed in the base equipment and the mobile(s) being called for commu-nication to occur. In addition, to receive standard group calls, the receiving mobile must be programmed to detect the transmitted talk group ID code. With conventional operation, a busy channel condition is detected automatically if the busy channel lockout (transmit disable on busy) feature is programmed. Otherwise, it must be detected manually. An out-of-range condition is not indicated by special tones or messages as with SMARTNET operation because there is no initial data exchange with the repeater that allows this condition to be detected. Operating features unique to conventional channels are described in Section 5.

GENERAL OPERATION173.8.3 SMARTNET/SMARTZONE MODEThis is a trunked operating mode in which auto-matic access is provided to several RF channels. ID codes are used 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. SMARTNET and SmartZone operation and programming is very similar. Basically, SMARTNET operation is limited to a single repeater site and Smart-Zone operation allows automatic roaming between sites. Enhanced SMARTNET/SmartZone features include roaming (SmartZone only), telephone*, private, and emergency calls, Call Alert™, and messaging. Either analog or digital signaling may be used. 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. Once a control channel is found, the alias (name) of the selected channel is displayed and the radio attempts to register on the radio system. 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” (early units) or “Out Rnge” (later units) is displayed and the radio continues to search for a control channel.The control channel transmits and receives system information to and from all radios registered on the system. Therefore, once a control channel is found, it is continuously monitored for incoming call infor-mation and is used to make call requests. The radio automatically changes to a traffic channel to place and receive calls and then returns to the control channel when the call is complete. Operating features unique to SMARTNET/SmartZone channels are described in Section 6.3.8.4 P25 TRUNKED MODEThe P25 Trunked operating features are very similar to the SmartZone type just described. Since SmartZone features are also similar to SMARTNET features, all three modes are described in the Section 6. Some differences between the P25 Trunking and SmartZone modes are as follows:•Digital signaling is always used with P25 calls. Either analog or digital signaling may be used for SmartZone calls.•Calls made to a specific mobile in the P25 mode are called Unit Calls. In the SMARTNET/SmartZone mode they are called Private Calls. •Messaging is not available with P25 calls.•Telephone calls are currently not available in this mode. •The P25 control channel data rate is 9600 baud and the digital voice data rate is also 9600 baud. With SmartZone operation, the control channel data rate is 3600 baud (both digital and analog calls) and the narrowband digital voice data rate is 9600 baud.•The P25 mode uses a system ID, Wide Area Communications Network (WACN) ID, and RF Subsystem ID (RFSS). The SmartZone mode does not use the WACN and RFSS IDs.•P25 Unit IDs can be 1-16,777,215 (000001-FFFFFF hex) and SmartZone Unit IDs can be 1-65,535 (0001-FFFF hex).3.8.5 SYSTEMS, CHANNELS, AND ZONESA zone and channel are selected to place and receive calls. The following describes the relationship between systems, channels, and zones.SystemsA system is a collection of channels or talk groups belonging to the same repeater site. It defines all the parameters and protocol information required to access a site. Up to 16 systems of any type can be programmed. The maximum number of channels assignable to a system is limited to 256 with standard models or to approximately 512 with the 512-channel option. Chan-nels may also be limited by available memory space as described in the following information.* Telephone calling is currently not available.

RADIO-WIDE FEATURES18ChannelsA channel selects a radio (RF) channel or talk group as follows:Conventional Analog Mode - A channel selects a specific radio channel, Call Guard (CTCSS/DCS) squelch coding, and other parameters unique to that channel.Conventional Project 25 Mode - A channel selects a specific radio channel, NAC squelch coding, talk group ID, and other parameters unique to that channel. Mode - A channel selects a specific talk group ID and other parameters unique to that talk group.SMARTNET/SmartZone and Trunked Project 25 Modes - A channel selects a specific talk group, announcement group, emergency group, and other parameters unique to that talk group.A maximum of up to 512 channels can be programmed with the preceding modes (with the 512-channel option). These channels can belong to a single system or multiple systems. The maximum number is also limited by the available memory. For example, since more memory is required to program a SMARTNET system than a conventional system, the total number of channels decreases as the number of SMARTNET channels increases. The programming software displays a bar graph which shows the amount of available memory space that is used by the current data. ZonesA zone is a collection of up to 16 channels of any type. For example, a zone could include 12 conven-tional channels and 4 SMARTNET channels. One use of zones may be to program the channels used for operation in a different geographical areas. The maximum number of zones is limited to 16 with stan-dard models or to 32 with the 512-channel option.SECTION 4 RADIO-WIDE FEATURES4.1 OPTION SWITCHESAlmost all the buttons on this transceiver are programmable. The programmable switches are as follows:•On the side panel, the three switches above the PTT switch (see Figure 2-2 on page 12).•On the top panel, the rotary three-position switch and the orange switch (see Figure 2-1 on page 11).•On the front panel, F1 and F2 unless the menu mode is used (see next section), and F3 and F4.•With DTMF keypad models, all 12 DTMF keys.The functions that can be controlled by option switches are shown in Table 4-1. Each option switch can be programmed to control a different function in each of the three operating modes. For example, F3 can control one function when a conventional channel is selected, another when a SMARTNET/SmartZone channel is selected, and still another when a Project 25 trunked channel is selected. 4.2 MENU MODEMost functions that can be controlled by an option switch can also be controlled by the menu mode. The functions that can be controlled by the menu mode are shown in Table 4-1. Functions can be controlled by both an option switch and a menu parameter if desired.Menu Mode ButtonsWhen the menu mode is used, the F1 and F2 switches become dedicated menu mode control MenuExitBack/ MenuSelect/EnterMenuScrollUp/Down

RADIO-WIDE FEATURES19switches. The F1 switch is Back/Clear, and the F2 switch is Menu Select/Enter. If the menu mode is disabled, these switches can be programmed for other functions. Only the enabled menu items which apply to the selected channel type are displayed. For example, if a conventional channel is selected, only the enabled functions for conventional channels are displayed. When in the menu mode, messages continue to be received on the selected channel. However, the display does not indicate who is calling. Pressing the PTT switch exits the menu mode and keys the transmitter.The menu mode operates as follows:1. To select the menu mode, press the F2 key. Up to three menu parameters are then displayed as shown in the preceding photo.2. To scroll up or down through the menu parameter list, press the Up/Down switch. The selected parameter is indicated by a dark bar.3. To display the available modes for a highlighted parameter, press the F2 switch. The currently selected mode is indicated by an asterisk.4. Press the Up/Down switch to highlight the desired mode. Then press the F2 key to select that mode.5. To step back to the previous level or exit the menu mode, press the F1 (Clear) key.4.3 TIME-OUT TIMERThe time-out timer disables the transmitter if it is keyed continuously for longer than the programmed time. It can be programmed for 15 seconds to 3 minutes, 45 seconds or it can be disabled. If the transmitter is keyed for longer than the programmed time, the transmitter is disabled, a contin-uous 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. A different time can be programmed for each system, and the timer can be enabled or disabled on each conventional channel. With conventional chan-nels, a penalty time may also be programmed that prevents transmissions for a certain time after the transmitter is disabled (see Section 5.6).One use of this feature is to prevent a channel from being kept busy for an extended period by an accidentally keyed transmitter. It can also prevent possible transmitter damage caused by transmitting for an excessively long period.4.4 HOME ZONE/CHANNEL SELECTIf the Home Zone option switch or menu param-eter is programmed, it selects the preprogrammed home zone. The selected channel is displayed if the channel switch is enabled, and the preprogrammed home channel is selected if it is disabled. The trans-ceiver is also programmed so that either the home or last selected zone is selected when power is turned on. Refer to Section 3.3 for more information.4.5 POWER OUTPUT SELECTEach conventional channel and SMARTNET/SmartZone and P25 Trunked system can be programmed for high, low, or switchable power. If the High/Low Power option switch or menu parameter is programmed and selectable power is programmed on the current channel or system, high and low trans-mitter power can be selected. All models support high and low power. The new level is flashed in the display as either “HI POWER” or “LOW POWER”. If selectable power is not permitted on the current channel, “FIXED LOW” or “FIXED HIGH” is flashed and no change occurs. The selected power level for a channel is permanent until it is manually changed again. The low power mode may be automatically selected during a low battery condition (see Section 3.4). 4.6 ALERT TONE SELECTThe various alert tones that sound are described in Section 7.1. These tones can be turned on and off if the Alert Tone option switch or Tones menu parameter is programmed. When all tones are off, “TONE OFF” is momentarily displayed, and when all tones are on, “TONE ON” is momentarily displayed. If this switch or menu parameter is not programmed, tones are fixed* This feature requires 51xx operating (Flash) software 1.9.0 or later and PCConfigure 1.20 or later.

RADIO-WIDE FEATURES21in the on or off mode by programming. If the Surveil-lance mode is programmed (see following), tones are totally disabled.The Alert Tone volume** can be adjusted relative to the volume control setting. This is done by programming and also by the user if the Tone Volume Adjust option button or menu parameter is programmed. Relative levels of –170 to +170 can be set with “0” the default setting. A minus value decreases the tone volume and a plus value increases it. The user adjusted level permanently overrides the programmed level if applicable.4.7 SURVEILLANCE MODEIf the Surveillance mode* is programmed, the backlight, all alert tones, and front panel LED indi-cator are totally disabled in all operating modes. This feature can be turned on and off** by the user if the Surveillance Mode option button or menu parameter are programmed. The user selected mode permanently overrides the programmed mode if applicable. 4.8 SCANNING4.8.1 INTRODUCTIONScanning monitors the channels in the scan list for messages that the transceiver is programmed to receive. When a message is detected, scanning stops and the message is received. Shortly after the message is complete, scanning resumes (unless it has been disabled). There are two basic scan modes available: Stan-dard and Radio Wide. The operation of the standard type is unique to the type of channel selected, and the operation of Radio Wide type is the same regardless of the type of channel selected. Only one type can be enabled at a time. For example, if standard scanning is enabled and radio wide scanning is selected, standard scanning is automatically disabled and vice versa. More information on these types of scanning follows.4.8.2 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 and likewise for SMARTNET/SmartZone and Project 25 Trunked channels. More information on how standard scan-ning operates in these modes is located in the following sections:Conventional Mode - Section 5.11Other Modes - Section 6.12Standard scanning is turned on and off by the Scan option switch or menu parameter as follows. If this switch or menu parameter is not programmed, standard scanning is not available.•Enable scanning using the Scan option switch or menu parameter. Scanning is enabled when the icon is displayed. •To turn scanning off, press the Scan option switch again or select “Off” in the scan menu. Scanning is disabled when the icon is no longer displayed. •If the zone or channel is changed while scanning is selected, scanning continues on the same or a different scan list (see “Standard Mode Scan Lists” on page 22). NOTE: Each SMARTNET/SmartZone and P25 trunked channel can be programmed so that scanning is auto-matically enabled when the channel is selected.4.8.3 RADIO WIDE SCANNING NOTE: Use radio wide scanning only if two types of channels need to be scanned at the same time such as conventional and SMARTNET/SmartZone. Otherwise, use the more efficient standard scanning because there is less chance of missed calls.Radio wide scanning monitors the channels in the preprogrammed radio-wide scan list. This scan list can include up to 16 channels of any type and assigned to any zone (see “Radio Wide Scan List” on page 22). Radio wide scanning is turned on and off by the Radio Wide Scan option switch or menu parameter as follows. If this switch or menu parameter is not programmed, radio wide scanning is not available. * This feature requires 51xx operating (Flash) software 1.5.0 or later and PCConfigure 1.17 or later. ** This feature requires 51xx operating (Flash) software 1.9.0 or later and PCConfigure 1.20 or later.

RADIO-WIDE FEATURES22•Enable Radio Wide Scanning using the Radio Wide Scan option switch or menu parameter. As with standard scanning, radio wide scanning is indicated when the icon is displayed. •To turn radio wide scanning off, press the Radio Wide Scan option switch again or select “Off” in the menu. Scanning is disabled when the icon is no longer displayed.•If the zone or channel is changed while radio wide scanning, scanning continues normally.4.8.4 SCAN HOLD TIMEWhen a message is received or transmitted while scanning, there is a delay before scanning resumes. The delay after receiving a call prevents another message from being received before a response can be made. The delay after transmitting a call ensures that a response is heard instead of another message occurring on some other channel. Separate delay times are programmable for Radio Wide and Standard scanning. With radio wide and conventional standard scanning, delays of 0-7.5 seconds are programmable in 0.5-second steps. With SMARTNET/SmartZone and P25 Trunked standard scanning, a scan delay of 2-10 seconds can be programmed in 0.5-second steps. 4.8.5 TRANSMITTING IN THE SCAN MODEWhen the transmitter is keyed while scanning is enabled, the transmission may occur on various channels as follows. Conventional Operation - Transmissions can be programmed to occur on the priority, selected, or receive channel. Refer to Section 5.11 for more information.SMARTNET/SmartZone/P25 Trunked Operation - If scanning is halted to receive a message, program-ming determines if transmissions occur on the selected or active channel. Transmissions at other times occur on the selected channel. 4.8.6 NUISANCE CHANNEL ADD/DELETEWith standard scanning, channels can be tempo-rarily deleted from the scan list, for example, if messages become annoying. This feature is not avail-able with radio wide scanning. Channels can also be permanently added or deleted from a scan list as described in Section 4.9.5. Proceed as follows to temporarily delete a nuisance channel:NOTE: The selected channel and also priority chan-nels 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 (about 1 second).2. The channel is then deleted and scanning of the remaining channels in the scan list resumes.3. Deleted channels are added back into the scan list if any of the following occur:•Scanning is turned off and then on again using the Scan option switch or menu parameter.•Transceiver power is turned off and then on again.•The selected channel is changed.4.9 SCAN LISTS4.9.1 STANDARD MODE SCAN LISTSNOTE: The selected channel is always scanned.A scan list is simply the channels that are scanned when scanning is enabled. With all operating modes, as many standard scan lists as are required can usually be programmed (up to 256). The only limitation is the available memory. Each scan list can include up to 256 channels/talk groups (or optionally up to 512). Refer to Sections 4.9.4 and 4.9.5 which follow for informa-tion on selecting and editing standard scan lists. 4.9.2 RADIO WIDE SCAN LISTWith radio wide scanning, there is only one scan list available regardless of the type of channel selected, and it is not user programmable. This scan list can contain up to 16 channels of any type. For example, it could include six conventional channels and ten SMARTNET/SmartZone channels.

RADIO-WIDE FEATURES234.9.3 DETERMINING WHICH CHANNELS ARE IN SCAN LISTThe channels in the radio-wide and conventional scan lists are indicated as follows. Channels in the SMARTNET/SmartZone/P25 Trunked lists are indi-cated only when editing a scan list.1. To view the conventional scan list, enable standard scanning using the Scan switch or menu parameter. Likewise, to view the radio wide scan list, enable radio wide scanning using the Radio Wide Scan switch or menu parameter. Also select the scan list if applicable as described in the following “Selecting a Scan List” description. 2. Select the desired zone and then scroll through the channels by rotating the channel switch. When the displayed channel is in the scan list (scanned normally), the icon is displayed. 4.9.4 SELECTING A SCAN LISTNOTE: Only standard scan lists are selectable.With conventional operation, selecting another conventional channel does not change the scan list. However, the scan list can be temporarily changed by the user if the Scan (List) Select option switch or menu parameter is programmed (see following). The programmed default scan list is automatically reselected on power up.With SMARTNET/SmartZone operation and Project 25 trunked operation, each channel (talk group) can be programmed to select one of the programmed lists or so that scanning is disabled (No List). In addition, each channel can be programmed so that scanning is automatically enabled (Auto Scan) when it is selected. If the Scan (List) Select option switch or menu parameter is programmed, the list that is selected by all talk and announcement groups in the current system can be temporarily changed by the user as follows. “No List” (scanning disabled) or “Programmed” (default list) can also be selected if desired). The programmed default scan list is automat-ically reselected on power up. Change the currently scan list as follows. 1. With scanning disabled ( icon not displayed), press the Scan List option switch or select the Scan Selct menu parameter.2. The currently selected list is displayed as “List x”, where “x” is the currently selected list. To exit without changing the selected list, simply press the Scan List option switch again or the F1 key.3. To select another list, press the Up/Down switch. When the desired list is displayed, select it and exit this mode by pressing the Scan List option switch again or the F1 or F2 key.4.9.5 EDITING A SCAN LISTIf the Scan Edit option switch or menu parameter is programmed, conventional, SMARTNET/SmartZone, and P25 Trunked standard scan lists can be user programmed as follows. Changes are perma-nent (cycling power does not reselect a default condition). 1. Make sure that both standard and radio wide scan-ning are off ( icon not displayed). Select a conventional or SMARTNET/SmartZone/P25 Trunked channel corresponding to the scan list being programmed.2. Select the scan edit mode using the Scan Edit option switch or menu parameter. This mode is indicated by in the display. 3. If applicable, select the list to be edited by pressing the Up/Down switch. Select the desired list by pressing the F2 key. The selected list is indicated as “LIST x”. If user programming is disabled on a list, (conventional only) “NO EDIT” is momentarily displayed and it cannot be edited.4. Select the channel you want to add or delete by pressing the Up/Down switch. After the last channel in the current zone is displayed, the first valid channel in the next zone is displayed and vice versa. Lists are limited to 256 channels (or optionally up to 512). If an attempt is made to add more than 256 or 512, “LIST FULL” is displayed and a channel must be deleted before another can be added.

24CONVENTIONAL MODE FEATURESNOTE: Priority channels can be deleted.5. If the selected channel is in the scan list (scanned), the icon is displayed. To change the status of the displayed channel, press the F2 (Enter) switch. With conventional channels only, if the selected scan list is programmed with fixed priority channel(s), the next press of F2 makes the current channel the priority channel indicated by . If dual priority channels are used, pressing F2 again makes it the second priority channel indicated by . Then pressing F2 again takes the channel out of the scan list. Refer to Sections 5.11.3 and 5.11.4 for more information on priority channel sampling.6. To exit this mode and save the changes, press the F1 (Exit) key or the Scan Edit option switch again.2SECTION 5 CONVENTIONAL MODE FEATURES5.1 INTRODUCTIONAn overview of the conventional operating mode is located in Section 3.8.2. The following information describes the features unique to analog and digital (Project 25) conventional operation. Refer to the preceding “Radio Wide Features” section (4) for infor-mation on features common to all operating modes.5.2 MONITORING BEFORE TRANSMITTINGWith conventional operation, you may need to manually monitor the channel before transmitting to make sure that it is not be used by someone else. If you were to transmit while someone else was using the channel, you would probably disrupt their conversa-tion. With SMARTNET/SmartZone and P25 Trunked operation, monitoring is performed automatically. Monitor conventional channels automatically or manually as follows:Automatic Channel MonitoringIf the selected channel is programmed for Busy Channel Lockout (also called Transmit Disable On Busy), monitoring is performed automatically. Refer to Section 5.4 for more information on this feature.Manual Channel MonitoringThe automatic monitoring just described may occasionally disable the transmitter when the channel is not in use, such as if the repeater has extended hang time. In this case, you may not want to use it and the channel must then be monitored manually as follows:Busy Indicator - With scanning disabled, note if the multi-function indicator on the front panel is steady green. If it is not, the channel is not being used and a call can be transmitted. It it is green, a carrier is being detected, so the channel may be busy (see following). Monitor Mode - There may be times when a busy condition is indicated even though no one is using the channel. Monitoring should then be performed by disabling Call Guard squelch (or group ID detect on Project 25 channels). This is usually done by selecting the Monitor Mode (see following) or by the Normal/Selective option switch or menu parameter (see Section 5.5.5). 5.3 MONITOR MODEThe monitor mode unsquelches the receiver and monitors the channel even if a carrier is not detected. Other features of this mode are as follows:•Call Guard (CTCSS/DCS) squelch is disabled on analog channels and NAC and group ID detect are disabled on P25 (conventional) channels. •Busy Channel Lockout is overridden (see next section)•Scanning temporarily halts The Monitor Mode operates as follows:1. To monitor the transmit frequency for activity before transmitting, briefly press the Monitor option switch or select the Monitor menu “Tx Channel” parameter. The icon is then displayed to indicate the monitor mode and the receiver unsquelches.

CONVENTIONAL MODE FEATURES252. To monitor the receive frequency instead, press and hold the Monitor option switch until a tone sounds or approximately 2 seconds, or select the Monitor menu “Sqlch Ovrd” parameter. This can be used, for example, to improve reception if intermittent squelching is making a weak message difficult to understand.3. To disable the monitor mode and return to normal operation, press the Monitor option switch again of select the Monitor menu “Off” parameter.The Normal/Selective function disables Call Guard squelch and P25 group ID detect but not scanning and P25 NAC detect (see Section 5.5.5).5.4 BUSY CHANNEL LOCKOUTThe Busy Channel Lockout feature (also called Transmit Disable on Busy) automatically disables the transmitter if the channel is busy when the PTT switch is pressed. When the transmitter is disabled by this feature, “BUSY” is displayed, a busy tone sounds, and the transmitter is disabled.The Busy Channel Lockout feature can be programmed to operate as follows. Each conventional channel can be programmed differently.Off - Busy channel lockout is disabled and the trans-mitter keys even if the channel is busy.Noise - If a carrier is detected on the channel, the transmitter is disabled when the PTT switch is pressed.Tone (NAC) - If an incorrect Call Guard (CTCSS/DCS) or NAC code (see Section 5.16) is detected, the transmitter is disabled when the PTT switch is pressed. An incorrect code is any code other than the one programmed for the current channel.If Busy Channel Override is permitted by programming, it is possible to transmit even when the transmitter is disabled by this feature. Simply release the PTT switch and then quickly press it again.5.5 CALL GUARD SQUELCH5.5.1 INTRODUCTIONTone or digital Call Guard squelch (also called CTCSS/DCS signaling) can be programmed on each conventional analog transmit and receive channel in any order desired. The reverse burst and turn-off code are always transmitted and also detected on channels programmed with Call Guard squelch. The Call Guard squelch feature eliminates distracting messages intended for others using the channel. This is done by using a subaudible tone or digital code to control the squelch. This tone or code is unique to a user or a group on that channel. This tone or code is transmitted with the voice signal but is not heard because it is in the subaudible range and is atten-uated by a filter. Call Guard squelch must be used in both the transmitting and receiving transceiver to be functional. 5.5.2 CALL GUARD SQUELCH ENABLE/DISABLEThe Normal/Selective option switch or menu parameter (if programmed) can be used to disable receive Call Guard squelch on analog channels or group ID code detection on P25 channels. When selec-tive squelch is disabled, “Sq Normal” is flashed in the display, and when it is enabled, “Sq Select” is flashed. When “Normal” is selected, the receiver unsquelches only if a carrier is detected, and scanning and Project 25 NAC detection are not disabled. The selected mode is in effect until it is manually changed again. Selecting another channel or cycling power does not reselect a default condition. 5.5.3 TONE CALL GUARD SQUELCHTone-type Call Guard squelch utilizes subaudible CTCSS tones from 67-254.1 Hz. Although there are 42 tones assigned, those above 33 (210.7 Hz) are normally not used because of their close proximity to the voice band which starts at 300 Hz. In addition, tones 11 (97.4 Hz), 39 (69.3 Hz), 40 (206.5 Hz), 41 229.1 Hz), and 42 (254.1 Hz) are normally not used because they may cause interference with adjacent tones.

CONVENTIONAL MODE FEATURES26A reverse burst is transmitted when the push-to-talk switch is released and also detected when calls are received. It is a 180-degree phase reversal for a period of time determined by the tone frequency, and it elimi-nates the squelch tail (noise burst) in the receiving transceiver. Both the transmitting and receiving trans-ceiver must be equipped with this feature for it to be utilized. 5.5.4 DIGITAL CALL GUARD SQUELCHDigital Call Guard squelch (DCS) uses digital data instead of subaudible tones to control the squelch. This data consists of continuous repetitions of 23-bit words. No bit or word synchronization information is used. When the push-to-talk switch is released, a turn-off code is transmitted which eliminates the squelch tail similar to the reverse burst. Although there are thousands of possible code combinations with 23 bits, only 83 are unique with the data scheme used. The number specified when the code is programmed is actually a seed for a special algorithm used to generate the 23-bit data word. The data is transmitted at a rate of 134.4 bits per second. Therefore, approximately six words are transmitted each second. When the data is decoded, 23-bit samples are taken and then the bits are rotated to determine if a valid code was received. 5.5.5 SELECTIVE SQUELCH CODE SELECT (CTCSS/DCS/NAC)NOTE: Call Guard codes can be permanently repro-grammed by keypad programming (see Section 5.17).A different CTCSS/DCS/NAC squelch code can be temporarily selected if the Selective Squelch option switch or menu parameter and a CTCSS/NAC code list have been programmed. This feature allows the normal transmit and receive Call Guard programming to be temporarily overridden with a code selected from this list. The CTCSS/DCS/NAC list is programmed with up to sixteen tone (CTCSS) or digital (DCS) Call Guard codes. In addition, for operation on Project 25 channels, each position can be programmed with an NAC code. When the Call Guard code is changed using this feature, it remains selected even if other channels are selected. However, if transceiver power is cycled or a talk-around channel is selected, the normal codes are reselected. When scanning, the selected code also applies to all scanned channels. If both analog and digital (Project 25) channels can be selected or scanned, the CTCSS/DCS code for the selected posi-tion is used for analog channels and the NAC code for the selected position is used for P25 channels. If a channel is programmed for mixed mode operation, the selective squelch type (analog or digital) programmed for the transmit mode determines the selective squelch type used. Proceed as follows to select a preprogrammed Call Guard code:1. Press the Selective Squelch option switch or select the Sqlch Code menu mode parameter. Then press the Up/Down 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 display, press the F2 (Select) key or 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. As previously described, the normal codes are also automatically reselected whenever transceiver power is cycled or a talk-around channel is selected.5.6 PENALTY TIMERA penalty timer may be programmed on conven-tional systems to prevent transmissions for the programmed time after the time-out timer disables the transmitter (see Section 4.3). The penalty timer can be programmed for the same times as the time-out timer, and timing starts when the PTT switch is released. If the PTT switch is pressed during the penalty time, the time-out indication occurs again and the transmitter remains disabled. When the penalty timer expires, a beep sounds and the transmitter can be keyed.

CONVENTIONAL MODE FEATURES275.7 CONVERSATION TIMERA conversation timer can be programmed on conventional systems in addition to the time-out timer (see Section 4.3). This timer limits the total length of a conversation rather than just the length of each trans-mission as with the time-out timer. The following is more information on this timer.•It can be programmed for times up to 7.5 minutes.•It is reset when the time between transmissions exceeds the time programmed for the penalty timer.•A warning beep sounds 5 seconds before this timer disables the transmitter.•When this timer disables the transmitter, a contin-uous tone sounds and the red transmit indicator turns off. The PTT switch must then be released until the penalty timer expires (indicated by a beep).5.8 REPEATER TALK-AROUNDNormally, all transmissions go through a repeater which usually increases range. However, there may be times when a mobile is out of range of the repeater and therefore unable to talk to anyone even though the mobile being called is only a short distance away. To allow communication in this situation, repeater talk-around can be selected. Transmissions then occur on the receive frequency which permits direct mobile-to-mobile communication.Repeater talk-around can be selected if the RTA option switch or menu parameter is programmed. When talk-around is enabled by this switch, is displayed. This feature remains enabled during scan-ning, and changing channels or turning power off does not change the selected condition. Talk-around is available on conventional channels only.5.9 DISPLAYING TRANSMIT/RECEIVE FREQUENCYIf the Displayed Information option switch or menu parameter is programmed (see Section 4.1), it can be used to display the channel frequency in megahertz. Pressing this switch toggles between displaying the standard channel alias and the channel frequency. The receive frequency is displayed when receiving and the transmit frequency is displayed when transmitting. This feature is available on conventional channels only.5.10 EMERGENCY ALARM AND CALLNOTE: The following enhanced conventional emer-gency features require 5100 operating (Flash) soft-ware 1.8.0 or later and PCConfigure 1.19 or later.5.10.1 INTRODUCTIONEmergency Alarms and Calls are separate func-tions that can be individually enabled or disabled on each analog and P25 conventional system. The Emer-gency option switch or menu parameter is required for these functions. Emergency Alarms and Calls are transmitted on the last selected talk group. The emergency hot microphone function can also be programmed with emergency alarms and calls. Then when the emergency switch is pressed, the microphone audio is enabled and the transmitter auto-matically keyed for the programmed hot microphone time (10-120 seconds). If “silent” emergency is programmed, no tones sound but the transmit indicator still lights. If the “Surveillance Mode” is enabled (see Section 4.7), all indicators, lights, and tones are disabled.5.10.2 EMERGENCY ALARMSAn emergency alarm is a special transmission on the selected talk group that alerts a dispatcher of an emergency situation. It is sent by simply pressing Emergency option switch or selecting the Emergency menu parameter on channel of a system programmed for emergency alarms. In the P25 conventional mode, a special emer-gency data transmission is sent, and in the conven-tional analog mode, it is a DTMF number that is sent in place of the Pre/Post ANI programming if appli-cable. If ANI is not programmed, it defaults to the “Pre” condition. The DTMF Emergency ID is programmed on the Conventional Radio Wide screen when programming the radio. Proceed as follows to activate an emergency alarm: 1. Select a channel of a system on which the Emer-gency Alarm is enabled and then press the Emer-gency option switch or select that menu parameter. The radio then begins automatically transmitting an emergency alarm and “EMERGNCY” is indicated in the display for 3 seconds.

CONVENTIONAL MODE FEATURES282. When the emergency alarm is acknowledged, “ACK RCVD” is briefly displayed and the emergency acknowledge tone (two beeps) sounds. This alert tone can be disabled if desired. Silent operation may also be programmed in which case no tone sounds and there is no indication that an acknowledgment occurred.3. The radio continues to transmit this message until an acknowledgment is received or until 30 attempts have been made. To exit this mode, power must be turned off. 5.10.3 EMERGENCY CALLSAn emergency call occurs if the PTT switch is pressed after pressing the Emergency switch or selecting the menu parameter as above and the system of the selected channel is programmed for emergency calls. If the PTT switch is pressed on a P25 channel, an emergency indication is sent according to the P25 standard (the emergency bit is set in the Common Air Interface). If it is pressed on an analog channel, the DTMF emergency ID is sent in place of the ANI DTMF PTT ID if applicable. To place this call, proceed as follows: 1. Select a channel of a system on which the Emer-gency Call is enabled and press the Emergency option switch or select that menu parameter. 2. To place the emergency call, manually press the PTT switch and begin speaking as with a standard call. If the channel is changed, operation continues on the new channel in the emergency mode.3. To exit this mode, power must be turned off.5.11 CONVENTIONAL MODE SCANNING5.11.1 GENERALChannel scanning features common to all oper-ating modes are described in Sections 4.8 and 4.9. The following information describes features unique to conventional operation.5.11.2 TRANSMITTING IN SCAN MODEEach conventional scan list can be programmed for one of the following modes. These modes deter-mine if priority sampling occurs and also the channel on which transmissions occur while scanning. Refer to the next section for more information on priority sampling.No Priority - No priority channel sampling occurs when the list is selected. The radio transmits on the selected channel.Priority/Tx Selected - Priority sampling occurs and the priority channel or channels are those programmed in the selected scan list. The radio transmits on the selected channel.Priority/Tx Priority (1) - Priority sampling occurs and the priority channel or channels are those programmed in the selected scan list. The radio trans-mits on the priority (1) channel.Priority (1) on Selected - The priority (1) channel is always the selected channel. The radio transmits on the selected channel. Talkback - No priority sampling occurs. The radio transmits on the channel of a call while scanning is halted. Then once scanning resumes, it transmits on the selected channel.5.11.3 PRIORITY CHANNEL SAMPLINGNOTE: The following describes priority sampling when scanning conventional channels. Priority sampling when scanning SMARTNET/SmartZone/P25 Trunked channels is described in Section 6.12.GeneralThe priority channel sampling feature ensures that when standard scanning, messages on the priority channel are not missed while listening to a message on some other channel. The transceiver can be programmed as just described so that the priority channel is a fixed channel programmed in the current scan list, the currently selected channel, or not used.

CONVENTIONAL MODE FEATURES29NOTE: Priority channel sampling (both analog and P25 channels) currently does not occur when receiving encrypted calls, and also when receiving P25 calls if equipped with Flash code 1.10 or earlier. In addition, the priority channel is not scanned if the active channel is an analog channel on the same frequency programmed with CTCSS/DCS squelch control.Either a single or dual priority* channels can be programmed if desired. With dual priority, a call on the second priority channel is interrupted by a call on the first priority channel but not vice versa. When scanning and the selected channel is a single or first priority channel, is indicated in the display. This indication is displayed regardless of whether the priority channel is fixed or always the selected channel. When it is a second priority channel, is displayed.The priority channel sampling frequency is deter-mined by the programmed Priority Lookback Time A (see description which follows). For example, if 2.0 seconds is programmed, the priority channel is sampled every 2.0 seconds when listening to a message on a non-priority channel. When not listening to a message, the priority channels are scanned in the normal scan sequence. With dual priority, the first and second priority channels are alternately sampled at the Lookback Time.Priority channel sampling occurs only with stan-dard conventional scanning. It does not occur with radio-wide scanning, when listening to any type of SMARTNET/SmartZone/P25 trunked call, encrypted call, or when transmitting (see preceding note). A series of “ticks” may be heard when the priority channel is sampled while listening to a message on some other conventional channel. The priority sampling times are programmed by the following parameters:Lookback Time A - This time determines how often the priority channel is checked for activity. Times of 0.25-4.00 seconds in 0.25-second steps can be programmed.Lookback Time B - This time determines how often the priority channel is checked once an incorrect Call Guard (CTCSS/DCS) or NAC code is detected. Since it takes much longer to detect an incorrect Call Guard signal than a carrier, this time should be relatively long to prevent the interruptions from making a message difficult to understand. Times of 0.5-8.0 seconds can be programmed in 0.5-second steps.5.11.4 CHANGING THE PRIORITY CHANNELIf a fixed priority channel is associated with the current scan list, it can be changed if the Priority option switch or menu parameter is programmed. With dual priority, this function changes only the first priority channel. To change both priority channels, use the Scan List Edit function described in Section 4.9.5. Proceed as follows to change the priority channel using the Priority option switch/menu parameter:1. Make sure scanning is disabled ( icon not displayed) and the desired scan list is selected (see Section 4.9). 2. Select the channel you want to be the priority channel and then press the Priority option switch or select that menu parameter. “Priority” is then flashed to indicate that the current channel is now the priority channel when scanning that list. Other indications that may occur are as follows:•If “No Priority” is displayed, priority sampling may not be enabled on the scan list.•If “Sel Chan” is displayed, the priority channel is always the selected channel and cannot be changed.•If no indication displayed, the scan list may not be user editable or the channel may not be in the scan list. 5.12 STANDARD CONVENTIONAL CALLSStandard conventional calls are placed to other mobile units monitoring the selected channel. The proper coded Call Guard squelch tone or code or P25 NAC may need to be transmitted by your radio for them to receive a call (see Sections 5.5 and 5.16.3).2* This feature requires 51xx operating (Flash) software 1.5.0 or later and PCConfigure 1.17 or later.

CONVENTIONAL MODE FEATURES30Placing a Standard Conventional Call1. Turn power on and set the volume as described in Section 3.1. Select the channel programmed for the mobile you want to call as described in Section 3.3.2. Monitor the channel automatically or manually as described in Section 5.2.3. Press the PTT switch and if the Busy Channel Lockout feature is programmed on the channel (see Section 5.4), the transmitter is automatically disabled if the channel is busy. Otherwise, busy and out-of-range conditions are not indicated. 4. Press (and hold) the PTT switch to talk and release it to listen. Receiving a Standard Conventional Call1. Select or scan the channel programmed for the call you want to receive (refer to Sections 4.8 and 4.9 for more scanning information).2. When the call is received, press the PTT switch to talk and release it to listen. If scanning, responses may occur on the priority, selected, or receive channel as described in Section 5.11.2. 5.13 DTMF/ANI SIGNALINGDTMF (Dual Tone Multi-Frequency) tones can be generated for ANI (Automatic Number Identifica-tion) and other purposes on conventional analog chan-nels. One of the following options may be enabled on each channel:Pre-Tx ANI - A preprogrammed ANI sequence is automatically sent each time the PTT switch is pressed.Post-Tx ANI - A preprogrammed ANI sequence is automatically sent each time the PTT switch is released. When an emergency alarm or call is placed, this ANI signaling is replaced by the Emergency DTMF ID (see Section 5.10).5.14 CLONE MODEThe Clone feature* enables one radio to program another with identical information. The PCConfigure programming software is not required. This feature is available with 51xx portables only. Other requirements are as follows:•The Clone menu parameter must be selectable by the master (sending) radio. This parameter is not required with the slave (receiving) radio. •The master and slave radios must be identical models (same frequency range and options). •Flash code Version 1.5.0 or higher is required with both radios (the version number is display briefly at power up). PCConfigure Version 1.17 or higher is also required to program the Clone menu parameter.Only zones with conventional analog and P25 channels can be transferred using this function. Any SMARTNET/SmartZone and P25 trunked informa-tion is not transferred. In addition, the P25 Unit ID, encryption keys, and the RSI ID and other OTAR information is not transferred. Cloned zones are indi-cated in the slave radio by an asterisk in the first char-acter position of the zone alias.Proceed as follows to program a radio using this feature:1. Turn the slave (receiving) radio off and connect it to the master (sending) radio using Cloning Cable, Part No. 023-5100-930. Turn the slave radio back on.2. On the master radio, select the Clone menu param-eter and press the F2 key. Either the “Zone” or “Complete” mode can then be selected. Operation in these modes is as follows:Zone - This mode allows channel information for only the selected zones to be transferred. Informa-tion programmed on the Global, Radio Wide, and By System screens is not changed. A list of the available conventional zones is displayed, and then to select a zone, highlight it and press the F2 key. A selected zone is indicated by an asterisk (*). After the desired zones are selected, scroll to “OK” and press F2 to begin the data transfer.* This feature requires 51xx operating (Flash) software 1.5.0 or later and PCConfigure 1.17 or later.

CONVENTIONAL MODE FEATURES31Complete - This mode transfers all conventional programming information from the master radio. This includes information on the Global, Radio Wide, and By System screens. Simply highlight “Complete” and press the F2 key to begin the data transfer.5.15 SINGLE TONE ENCODERThis feature allows the user to transmit a single tone by pressing the Single Tone Encoder option switch or selecting that menu parameter. Each conven-tional system can be programmed for a tone of 500-2500 Hz in 1 Hz steps with a duration of 0.5-2.5 seconds in 0.1 second steps. This feature is available only with Flash code 1.7.0 or later.5.16 PROJECT 25 MODE FEATURES5.16.1 UNIT ID CODEEach transceiver that operates on Project 25 (digital) channels is programmed with an eight-digit unit ID. This ID is unique for each transceiver and can be any number from 1-16,777,216. When power is turned on with a Project 25 channel selected, this ID is briefly displayed.5.16.2 GROUP ID CODEEach Project 25 channel is programmed with a group ID that determines which group of mobiles will receive the call. A call is received on a channel if a selected or scanned channel is programmed with that ID and the correct NAC is detected (see following). Group IDs can be any number from 0-65,535. Group ID detect can be disabled by the Normal/Selective squelch function described in Section 5.5.2 or the monitor mode described in Section 5.35.16.3 NETWORK ACCESS CODEProject 25 conventional channels also use a NAC (Network Access Code) to control which calls are received on a channel. The NAC can be 0-4095, and each transmit and receive channel can be programmed for a different code. Other operation, such as moni-toring before transmitting, is similar to that of analog channels. NAC (and group ID) detect can be disabled by the monitor mode described in Section 5.3.5.16.4 P25 GROUP CALLSP25 group calls are placed by simply selecting the channel programmed for the desired group, monitoring the channel if required, and transmitting. Changing a Channel Talk GroupIf the Digital Talk Group Select option switch or Select TG menu parameter is programmed, the talk group assigned to a channel can be changed by the user. The new talk group continues to be assigned to the channel until it is manually changed again (cycling radio power or selecting another channel does not reselect a default talk group). Change the talk group assigned to a channel as follows:1. Select the channel to be changed and then press the Talk Group Select option switch or select the Select TG menu parameter. 2. Press the Up/Down switch until the alias (alphatag) of the desired talk group is displayed. 3. To select that talk group and return to normal oper-ation, press the Talk Group Select option switch again or the F2 switch. If talk group selection has been disabled on the channel by programming, “NO LIST” is displayed, a tone sounds, and no change occurs.5.16.5 P25 UNIT CALLSUnit Calls (also called Individual Calls) can be placed to a specific radio on a Project 25 channel if the Unit Call option switch or menu parameter is programmed. Only the individual ID of the target radio is sent (a talk group ID is not sent). The mobiles that can be called are preprogrammed in the unit call list. To receive a Unit Call, the RF channel of the call must be selected or scanned and the correct NAC and unit ID must be detected. The ID of the calling mobile is then transmitted back. To respond to the call, the transceiver must be programmed with the Unit ID option switch or menu parameter, and have a Unit Call programmed for the ID of the calling mobile.* This feature requires 51xx operating (Flash) software 1.9.0 or later and PCConfigure 1.20 or later.

CONVENTIONAL MODE FEATURES32Place and receive a Unit Call as follows:1. To transmit a Unit Call, press the Unit Call option switch or select the Unit Call menu parameter. The alias (tag) of the last Unit Call is displayed.2. If required, press the Up/Down switch to display the desired call. The alias and ID of the calls that have been programmed are alternately displayed.3. Press and then release the PTT switch. Ringing is then heard and “WAIT” displayed to indicate that the mobile is being rung. To disable this ringing but not the call, briefly press the PTT switch again. Ringing occurs for 20 seconds or until the call is answered, whichever occurs first.4. When a Unit Call is received, two beeps sound (if tones are enabled), and “Call Rcvd” and the alias or frequency of the currently selected talk group are alternately flashed. In addition, the transceiver can be programmed to display the alias of the talk group on which the call is being received (if it is not the same as the selected talk group) and/or the ID of the mobile placing the call. The time each is displayed is programmable** for 0.5-7.0 seconds or infinite.5. To respond, select the Unit Call mode by pressing the Unit Call option switch or selecting the menu parameter. The following operation then occurs:•If a unit call has been programmed with the ID of the calling mobile, it is automatically selected. A response can then be made without changing the selected channel.•If no Unit Call has been programmed with the ID of the calling mobile, a response cannot be made in this mode.•If the call timer times out (set by programming) or the channel is changed before a response is made, the unit call mode is exited. 5.16.6 CALL ALERTGeneralThe Call Alert™ feature* allows pages to be sent and received on P25 conventional channels.

The radio then begins automatically transmitting an emergency alarm data message and “EMERGNCY” is indicated in the display for 3 seconds.2. When the emergency alarm is acknowledged, “ACK RCVD” is briefly displayed and the emergency acknowledge tone (two beeps) sounds. Silent opera-tion may also be programmed in which case no tone sounds and there is no indication that an acknowl-edgment occurred.3. The radio continues to transmit this message until an acknowledgment is received or the programmed number of attempts have been made. To exit this mode, power must be turned off. 6.10.3 EMERGENCY CALLSAn emergency call urgently requests access to a voice channel (an emergency tone usually does not sound at the console). To place this call, proceed as follows: 1. Select a SMARTNET/SmartZone or P25 Trunked channel that has this feature enabled and press the Emergency option switch or select that menu parameter. The emergency mode is indicated when “ACK RCVD” is briefly displayed and then “EMERGNCY” and the emergency talk group are alternately displayed. 2. To place the emergency call, manually press the PTT switch and begin speaking as with a standard call. All group calls which follow are then emer-gency calls (private, telephone, and call alert calls are not allowed). If the channel is changed, the call is made on the emergency talk group programmed for the new channel.3. To exit this mode, power must be turned off.6.11 FAILSOFT OPERATIONIf a failure occurs in the SMARTNET/Smart-Zone or P25 Trunked system so that it cannot be used, the system directs the transceiver to automatically enter the failsoft mode. When in this mode, “FAIL-SOFT” and the alias of the selected channel are alter-nately displayed. A failsoft tone may also be heard, depending on how the repeater is programmed.When in the failsoft mode, operation is in the conventional mode on the preprogrammed failsoft channel (a different failsoft channel can be programmed on each talk group). If a transmission is attempted before a failsoft channel is located, a contin-uous tones sounds until the PTT switch is released. When the radio system returns to normal operation, this is automatically detected and normal operation resumes. 6.12 SMARTNET/SMARTZONE/P25 TRUNKED SCANNING FEATURES6.12.1 GENERALScanning on a SMARTNET/Smartzone and P25 Trunked systems is called Priority Monitor Scan. The following are unique features of this type of scanning. For general scanning information applicable to all operating modes, refer to Sections 4.8 and 4.9. •Scanning is turned on and off by the Scan option switch or menu parameter. Talk groups (channels) can be programmed so that scanning automatically starts when the talk group is selected (Autoscan).

SMARTNET/SMARTZONE/P25 TRUNKED FEATURES43•When responding to calls in the scan mode, the programming of the Talkback Scan parameter deter-mines if a response always occurs on the talk group of the call (Active Group) or the Selected Group if they are different. Transmissions at other times always occur on the selected talk group.•Each talk group can be programmed to select one of the programmed scan lists or “No List” (scanning is disabled). If scanning is enabled and the selected channel does not permit scanning, it is automatically enabled again when a channel is selected that permits scanning.•Up to 256 scan lists, each with up to 256 talk groups from the same system can be programmed. The selected scan list can be temporarily changed as described in Section 4.9.4 and edited as described in Section 4.9.5.•In addition to calls on channels in the scan list, pages, private/unit calls, and telephone* calls are received while scanning. Private and telephone calls are not interrupted by priority messages. 6.12.2 PRIORITY TALK GROUP SAMPLINGOne talk group in the scan list can be designated a priority talk group by programming or it can be the selected talk group. When scanning, messages on a non-priority talk group are interrupted by messages on the priority talk group. Priority scanning must also be supported at the system level for it to occur as programmed in the radio. 6.13 DYNAMIC REGROUPINGThe dynamic regrouping feature allows a dispatcher to change the current talk group or switch mobiles to a predefined regrouping channel to receive an important message. When the console issues a regroup order, the transceiver switches to the prepro-grammed regroup talk group. If the lock mode was not specified, the selected talk group can be manually changed and the previous talk group is reselected if power is cycled. If a locked regroup command is received, the displayed talk group cannot be changed manually or by cycling power. It can be changed only after a clear order is received from the console. Dynamic regrouping operates as follows:1. When this command is received, alternating tones sound and the transceiver automatically changes to the regrouping channel and “DYN REGRP” is displayed. 2. Manually select the channel corresponding to that alias. If this is not done, transmission still occurs on the new channel, but the alternating tones sound each time the PTT switch is pressed.3. Talk and listen as usual. The dispatcher cancels dynamic regrouping which is indicated by a short tone. If a standard channel is not selected after this occurs, transmission is not allowed if the talk group is assigned as a dynamic regrouping talk group only. If it is assigned as a normal talk group, normal trans-missions are allowed. 6.14 SMARTZONE AND P25 TRUNKED UNIQUE FEATURES6.14.1 INTRODUCTIONAs described in Section 3.8.3, the SmartZone® mode provides wide area coverage by allowing roaming between SMARTNET and conventional sites. The P25 Trunked mode can provide access to a single trunked site or roaming between several trunked sites. Operation in these modes is the same as just described in the preceding sections (6.1-6.13) with the following additional features:6.14.2 BUSY OVERRIDEThe busy override feature is enabled at the system level by the system manager and is not a program-mable radio feature. It allows a call to be placed even if not all sites you are calling have a free traffic channel. The only sites guaranteed to be included are the Critical Sites and the sites where a Critical User is located. This feature 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 tone sounds with the PTT switch pressed, busy override is occurring.* Telephone calling is currently not available.

MISCELLANEOUS44NOTE: Remember that not all members of the talk group are receiving your message. Missing members will start receiving your message as channels become available.6.14.3 SITE TRUNKINGSite trunking occurs when a site can no longer participate in wide area trunking. When site trunking is occurring, the radio searches for other sites that may provide wide area coverage. Site trunking ends when a wide area coverage site is located, the current site is operating again as a wide area coverage site, an out-of-range condition occurs, or the failsoft mode is entered.6.14.4 DETERMINING CURRENT SITE AND SEARCHING FOR NEW SITETo display the RSSI level of the current site, press the Site Search option switch or select that menu parameter. The display then indicates the current site number as “SITE xx” and the RSSI level as “RSSI xx”. This mode is then automatically exited.To scroll through the other programmed sites, press and hold the Site Search option switch while “SITE xx” or “RSSI xx” is displayed. 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. 6.14.5 LOCKING/UNLOCKING A SITEIt is sometimes desirable to stay on a site. To prevent the transceiver from searching for a new site, lock it on the current site by pressing the Site Lock option switch or selecting that menu parameter. The display then momentarily indicates the site alias to indicate that the current site is locked (“x” is the current site number). To unlock the site, press the Site Lock switch again or the F2 (Select) key and “UNLOCK” is momentarily displayed.

This usually refers to the program-ming performed by the PCConfigure programmer when the radio was set up, not to any programming a user can perform. If a feature is controlled by a front panel option switch and that switch is not available, it is probably not available. If the Keypad Programming option switch is available, you can reprogram some conventional channel parameters. Refer to Section 5.17 for more information.7.3 SPEAKING INTO MICROPHONEFor best results, hold the transceiver about 1-2 inches from your mouth and speak at a normal conver-sational 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.7.4 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 background noise when messages are received. You may still be out of range even though you can hear a message. The reason for this is that the signal you are receiving is usually transmitted at a higher power level than the one trans-mitted by your transceiver. Communication may be improved by moving to higher ground or away from shielding objects such as tall buildings or hills.7.5 LICENSINGA government license is usually required to operate this transceiver on the air. 7.6 TRANSCEIVER SERVICE If the transceiver is not responding to any key presses, the keypad may be locked. Refer to Section 3.6 for more information.

MISCELLANEOUS46If “PASSWORD” is briefly displayed when power is turned on and you are prompted to enter a password, the Power-Up Password feature is enabled. Refer to Section 3.2 for more information.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. Reprogram the radio.If no characters appear in the display, the battery may be discharged or defective. Try another battery. 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. If it still does not operate correctly, return it 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.
