MM-013994-001, Rev. Ap1 11 SAFETY SECTION

MM-013994-001, Rev. Ap1 12 1 SAFETY CONVENTIONS The following conventions are used throughout this manual to alert the user to general safety precautions that must be observed during all phases of operation, service, and repair of this product. Failure to comply with these precautions or with specific warning elsewhere in this manual violates safety standards of design, manufacture, and intended use of the product. Harris Corporation assumes no liability for the customer’s failure to comply with these standards. The WARNING symbol calls attention to a procedure, practice, or the like, which, if not correctly performed or adhered to, could result in personal injury. Do not proceed beyond a WARNING symbol until the conditions identified are fully understood or met. CAUTION The CAUTION symbol calls attention to an operating procedure, practice, or the like, which, if not performed correctly or adhered to, could result in damage to the equipment or severely degrade the equipment performance. The NOTE symbol calls attention to supplemental information, which may improve system performance or clarify a process or procedure. The ESD symbol calls attention to procedures, practices, or the like, which could expose equipment to the effects of Electro-Static Discharge. Proper precautions must be taken to prevent ESD when handling circuit modules. WARNING - The electrical hazard symbol indicates there is an electrical hazard present.

MM-013994-001, Rev. Ap1 13 2 SAFETY TRAINING INFORMATION The Harris P7300 portable radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as “Occupational Use Only,” meaning it must be used only during the course of employment by individuals aware of the hazards and the ways to minimize such hazards. This radio is NOT intended for use by the “General Population” in an uncontrolled environment. The P7300 portable radio has been tested and complies with the FCC RF exposure limits for “Occupational Use Only.” In addition, this Harris radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: • FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. • American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. • American National Standards Institute (C95.3 – 1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields – RF and Microwave. 2.1 RF EXPOSURE GUIDELINES CAUTION To ensure that exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines: • DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also cause the FCC RF exposure limits to be exceeded. A proper antenna is the antenna supplied with this radio by Harris or an antenna specifically authorized by Harris for use with this radio. (Refer to Table 6-1.) • DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the “TX” indicator appears in the display. The radio will transmit by pressing the “PTT” (Push-To-Talk) button. • Always transmit using low power when possible. In addition to conserving battery charge, low power can reduce RF exposure. • ALWAYS use Harris authorized accessories (antennas, batteries, belt clips, speaker/mics, etc). Use of unauthorized accessories may cause the FCC Occupational/Controlled Exposure RF compliance requirements to be exceeded. (Refer to Table 2-1.)

MM-013994-001, Rev. Ap1 14 • As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 1.1 cm (0.43 inches) from the body and at least 2.5 cm (1.0 inch) from the face when transmitting to ensure FCC RF exposure compliance requirements are not exceeded. However, to provide the best sound quality to the recipients of your transmission, Harris recommends you hold the microphone at least 5 cm (2 inches) from mouth, and slightly off to one side. Table 2-1: RF Exposure Compliance Testing Distances TESTED DISTANCES (worst case scenario) RADIO FREQUENCY Body Face 450-512 MHz 1.1 cm 2.5 cm 700/800 MHz 1.1 cm 2.5 cm The information in this section provides the information needed to make the user aware of RF exposure, and what to do to assure that this radio operates within the FCC RF exposure limits of this radio. 2.2 ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY During transmissions, this Harris radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites.

MM-013994-001, Rev. Ap1 15 3 OPERATING TIPS Antenna location and condition are important when operating a portable radio. Operating the radio in low lying areas or terrain, under power lines or bridges, inside of a vehicle or in a metal framed building can severely reduce the range of the unit. Mountains can also reduce the range of the unit. In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also improve communications. Vehicular operation can be aided with the use of an externally mounted antenna. Battery condition is another important factor in the trouble free operation of a portable radio. Always properly charge the batteries. 3.1 EFFICIENT RADIO OPERATION Keep the antenna in a vertical position when receiving or transmitting a message. Do not hold the antenna when receiving a message and, especially, do not hold when transmitting a message. Do NOT hold onto the antenna when the radio is powered on! 3.1.1 Antenna Care and Replacement Do not use the portable radio with a damaged or missing antenna. A minor burn may result if a damaged antenna comes into contact with the skin. Replace a damaged antenna immediately. Operating a portable radio with the antenna missing could cause personal injury, damage the radio, and may violate FCC regulations. Use only the supplied or approved antenna. Unauthorized antennas, modifications, or attachments could cause damage to the radio unit and may violate FCC regulations. (Refer to Table 6-1.) 3.1.2 Electronic Devices CAUTION RF energy from portable radios may affect some electronic equipment. Most modern electronic equipment in cars, hospitals, homes, etc. is shielded from RF energy. However, in areas in which you are instructed to turn off two-way radio equipment, always observe the rules. If in doubt, turn it off!

MM-013994-001, Rev. Ap1 16 3.1.3 Aircraft • Always turn off a portable radio before boarding any aircraft! • Use it on the ground only with crew permission. • DO NOT use while in-flight!! 3.1.4 Electric Blasting Caps To prevent accidental detonation of electric blasting caps, DO NOT use two-way radios within 1000 feet of blasting operations. Always obey the "Turn Off Two-Way Radios" signs posted where electric blasting caps are being used. (OSHA Standard: 1926.900) 3.1.5 Potentially Explosive Atmospheres Areas with potentially explosive atmospheres are often, but not always, clearly marked. These may be fuelling areas, such as gas stations, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust, or metal powders. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Turn OFF two-way radios when in any area with a potentially explosive atmosphere. It is rare, but not impossible that a radio or its accessories could generate sparks.

MM-013994-001, Rev. Ap1 17 4 BATTERIES The P7300 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please read carefully, the battery information provided, to maximize the useful life of each type of battery. Do not disassemble or modify Lithium Ion battery packs. The Lithium Ion battery packs are equipped with built-in safety and protection features. Should these features be disabled or tampered with in any way, the battery pack can leak acid, overheat, emit smoke, burst, and/or, ignite. If the battery is ruptured or is leaking electrolyte that results in skin or eye contact with the electrolyte, immediately flush the affected area with water. If the battery electrolyte gets in the eyes, flush with water for 15 minutes and consult a physician immediately. 4.1 CONDITIONING BATTERY PACKS 4.1.1 Conditioning NiMH Battery Packs Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging and fully discharging the battery three (3) times using the tri-chemistry charger. The first time the battery is put into the charger, this unit will condition Nickel-based battery packs by automatically charging and discharging (cycling) the battery. Refer to the appropriate charger manual for details. CAUTION Failure to properly condition NiMH battery packs before initial use will result in shortened performance by the battery. 4.1.2 Conditioning NiCd Battery Packs A new NiCd battery does not require conditioning before use. However, Harris recommends periodically conditioning NiCd batteries to avoid the memory effect which results when a NiCd battery is repeatedly charged and not fully discharged, further resulting in a lower voltage and a lower capacity. Fortunately, both nominal voltage and capacity are restored through battery conditioning. Conditioning requires fully charging and fully discharging the battery three (3) times using the tri-chemistry charger. The first time the battery is put into the charger, this unit will condition Nickel-based battery packs by automatically charging and discharging (cycling) the battery. Refer to the appropriate charger manual for details.

MM-013994-001, Rev. Ap1 18 CAUTION Always use Harris authorized chargers and conditioners. Use of unauthorized chargers and conditioners may void the warranty. 4.1.3 Additional Information For more information regarding the proper care of portable radio batteries or establishing a battery maintenance program, refer to ECR-7367 which may be ordered by calling toll free 1-800-368-3277, then select option 7. 4.2 CHARGING BATTERY PACKS Battery chargers are available from Harris with nominal charge times. Combinations include single and multi-position charge units. Harris chargers are specifically designed for charging nickel-based and lithium ion battery packs. The chargers are chemistry-specific for the battery packs and automatically adjust the charging profiles accordingly. Refer to the appropriate charger manual for specific operating instructions. 4.2.1 Charging Guidelines Observe the following guidelines when charging a battery pack: • Avoid high temperature during charging. • Discontinue use if the charger is overheating. • Only charge Harris battery packs using a charger approved for use by Harris. • Do not leave batteries in the charger indefinitely. For best results, leave the battery in the charger for two to six hours after the Green Ready LED comes on. Then place the battery pack into service and fully discharge (as indicated by the radio low battery warning) before re-charging. If any faults are encountered while charging the battery pack, consult the charger’s manual to determine the cause and possible corrective action. 4.3 BATTERY PACK USAGE Both Nickel-based and Lithium ion batteries vary in capacity and life cycle. For instance, NiCd batteries have a longer life cycle than NiMH batteries whereas NiMH batteries have a larger capacity. However, both Nickel-based and Lithium ion type batteries require basic usage guidelines be followed in order to optimize the battery runtime or shift life. 4.3.1 Usage Guidelines The following guidelines will help optimize the battery runtime or shift life: • Ensure Nickel-based battery packs are fully discharged (as indicated by the radio low battery warning) before re-charging. Full discharge is not required for Lithium Ion battery packs. • Periodically condition Nickel-based battery packs. The frequency should be determined based on usage patterns (refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning) during routine use, the frequency of conditioning may be reduced. Lithium Ion batteries do not suffer from memory-effect and therefore do not require conditioning.

MM-013994-001, Rev. Ap1 19 Do not leave any Harris rechargeable batteries in a charger for more than a few days. 4.4 CHANGING THE BATTERY PACK 4.4.1 Removing the Battery Pack Make sure the power to the radio is turned OFF. CAUTION Although the P7300 has been designed to tolerate changing the battery pack without turning power off, Harris recommends turning the radio off before changing battery packs to ensure safety and best operation. 1. Press or pull both latches on either side of the battery pack  toward the bottom of the radio simultaneously. 2. Pull the battery  away from the radio. 3. Remove the battery pack from the radio.

MM-013994-001, Rev. Ap1 21 PRODUCT INFORMATION

MM-013994-001, Rev. Ap1 22 5 INTRODUCTION The P7300 series portable radio is available in two models: the P7350 Scan model with a limited 6-button front-mounted keypad and the P7370 System model with a 15-button DTMF front-mounted keypad. The UHF P7300 portable radio delivers end-to-end encrypted digital voice and IP data communications. It is designed to support multiple operating modes including: • EDACS® (Enhanced Digital Access Communications System) or ProVoice™ Trunked mode • P25 Trunked Mode • P25 Digital Conventional Mode • Conventional Analog mode The P7300 portables can include all of these modes or just one. Additional modes of operation can be added with software updates. The P7300 supports a full range of advanced digital trunking features, including voice group calls, priority scanning, emergency calls, late call entry, and dynamic reconfiguration. It performs autonomous roaming for wide area applications. High quality voice coding and robust audio components assure speech clarity. In the trunked modes, the user selects a communications “operating” system (i.e., EDACS, ProVoice, or P25) and group. While communicating in a trunked mode, channel selection is transparent to the user and is controlled via digital communication with the system controller (e.g., a CSD in an EDACS system). This provides advanced programmable features and fast access to communication channels. In Conventional Analog mode, the user selects a channel and communicates directly on that channel. A channel is a transmit/receive radio frequency pair. The exact operation of the radio will depend on the operating mode, the radio’s programming, and the particular radio system. Most features described in this manual can be enabled through programming. Consult your System Administrator for the particular features programmed into your P7300. Then refer to the corresponding section(s) within this manual for feature and operation information. 5.1 WATER RESISTANCE The P7300 series portable radios operate reliably even under adverse conditions. These radios meet MIL-STD-810F specifications for wind driven rain, humidity, and salt fog.

The voice modes are programmed on a per-group basis within each trunked system and on a per-channel basis within each conventional system.

MM-013994-001, Rev. Ap1 49 8.18.1 Clear Mode The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be monitored easily by unauthorized persons. Groups or channels programmed for clear operation cannot transmit or receive digital or private messages. 8.18.2 Digital Mode The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide improved weak signal performance and cannot be easily monitored with a standard receiver. Groups or channels programmed for digital operation transmit only digital signals. Message trunked group calls and individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or inoperative. 1. If receiving an analog message trunked call, the radio responds in the analog mode during the hang time on the working channel. 2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 3. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is transmitted in the mode defined by the system mode as programmed for the current system if the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-Call mode programmed in the list for that ID. The overdial DTMF tones are not available while in the Digital Mode. 8.18.3 Private Mode The Private Mode allows the radio to transmit encrypted messages and receive clear or private transmissions. The radio transmits private if the group/channel is programmed for private operation and forced operation is pre-programmed. If auto-select operation is pre-programmed and the radio is in the Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang time is active, the radio transmits private. Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An individual key is automatically selected on a per-group/channel basis according to the radio programming. Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks of 7 keys can be stored for private systems. The bank is specified per system. When operating on a group or channel programmed for Private Mode, all transmissions are private transmissions and the radio receives clear and private signals. The status icon is displayed when the Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the mode may be toggled between private and clear with the key, then following the selection mode rules. Radios programmed for forced private operation do not allow a change of the transmit mode.

MM-013994-001, Rev. Ap1 50 8.18.3.1 Displaying the Currently Used Cryptographic Key Number To display the Currently Used Cryptographic Key Number for either the system encryption key (for special call such as individual, phone, all, agency or fleet) or the group/channel key (for group or conventional calls), perform the following procedure: 1. Press the button. 2. Use the or button to select "DISP KEY." 3. Use the or button to toggle between displaying the system key (Figure 8-9) or the group/channel key (Figure 8-10). Figure 8-9: System Encryption Key Display Figure 8-10: Group/Channel Encryption Key Display 8.18.3.2 Key Zero All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while still pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds. A series of beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been zeroed. The display will indicate KEY ZERO. If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the radio before private communications may continue. 8.18.4 Private Operation 8.18.4.1 Receiving an Encrypted Call When receiving, the radio automatically switches between clear or private operation. If the transmission being received is an encrypted transmission, it will be decrypted, the icon will be displayed, the receiver will unsquelch, and the message will be heard in the speaker. For this to occur, the selected group or channel must be programmed for private operation and the correct cryptographic key must be loaded into the radio. 8.18.4.2 Transmitting an Encrypted Call 1. Select the desired group or channel. 2. Place the radio in Private Mode by pressing key; then follow the selection mode rules. On a System radio, the key can be used to toggle the Private Mode ON/OFF. When Private Mode is enabled, the icon is displayed.

MM-013994-001, Rev. Ap1 51 3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also, the Private Mode will be enabled if forced operation has been programmed in the radio. If a group or channel is not programmed for Private Mode operation, PVT DIS will be displayed if an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel in Private Mode. If the radio does not have the correct encryption key loaded, NO KEY# will be displayed and the call will not be transmitted. 4. Continue with standard transmission procedures. A Private Mode access tone will be heard when the PTT button is pressed. 8.18.4.3 Scanned Group Calls Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same group was available in private and entered in the scan list, it can receive clear and private calls, provided auto-select was programmed in the radio. The user can select transmitting on the scanned or selected group. If a group is entered in the scan list more than once and under different modes, (clear, digital, or private), then only the first occurrence of the group will be used. Table 8-7: Transmit/Receive Mode Compatibility for Digital Voice Operation GROUP/CHANNEL PROGRAMMING (TRANSMIT) CLEAR RECEIVE DIGITAL RECEIVE PRIVATE RECEIVE CLEAR Yes No No DIGITAL Yes Yes No PRIVATE Yes No Yes* *assumes the proper cryptographic key is loaded Conventional digital or encrypted channels require Channel Guard on the channel to operate correctly.

MM-013994-001, Rev. Ap1 54 8.19.4 Nuisance Delete A group can also be deleted from the scan list, if it is not the currently selected group, by pressing the key (P7350 model) or the key (P7370 model) during scan operation while the radio is displaying the unwanted group. The group will be deleted from the system's group scan list in the same manner as if done using the steps above. Deletions done in this manner will not remain deleted if the radio is powered OFF and then powered ON. 8.20 SCANNING TRUNKED SYSTEMS The radio can be programmed using Radio Personality Manager (RPM) with the following System Scan features. Then these features are automatically enabled when the radio is powered ON. A key or menu option is also defined to allow the System Scan features to be toggled during radio operation. The System Scan state will be maintained through system changes but will default to ON when the radio is powered ON. Enable/Disable via Menu Selection Press and then use the or buttons to scroll through the selections until SYS SCAN is displayed. Then press to toggle the System Scan state. The SYSC ON or SYSC OFF display message is displayed for two seconds to show the new state. Enable/Disable via Pre-Programmed Keypad Key Press the key pre-programmed to toggle System Scan and the SYSC ON or SYSC OFF display message is displayed for two seconds to show the new state. 8.20.1 Wide Area System Scanning The P7300 series radio can be pre-programmed through RPM for Wide Area System Scan operation for roaming across mobile systems. EDACS radio systems manage the radios assigned to the system via a control channel (CC). Upon the loss of the currently selected system's control channel, radios can be programmed to automatically scan the control channels of other systems. If a new control channel is found, the radio will switch to the new system and sound an alert tone. 8.20.2 Priority System Scan The radio can also be pre-programmed for Priority System Scan. The priority system is the desired or preferred system. While receiving the control channel of the selected system, the radio will periodically leave the selected system and search for the control channel of the priority system. This is done at a pre-programmed rate defined by the value in the Priority Scan Time control, unless the ProScan™ algorithm is enabled, as explained in the following sections. This priority scan timer is reset each time the PTT button is pressed or when the call is received. If the priority system control channel is found, or meets the predefined criteria (ProScan), the radio will automatically switch to the priority system. 8.20.2.1 Enabling the Wide Area System Scan Function If the radio cannot find the control channel of the selected system and begins to wide area system scan, the radio will only scan for the priority system control channel if the priority system is in the wide area scan list.

MM-013994-001, Rev. Ap1 55 8.20.2.2 When ProScan is Enabled The radio monitors the priority system and will switch to the priority system if the pre-preogrammed criteria ProScan options are met. If ProScan is enabled, the rate at which the radio will scan for the priority system is defined by the System Sample Time control, set in RPM, (refer to RPM On-Line Help). See Section 8.20.3 for more information on ProScan. 8.20.3 ProScan The radio may be programmed for ProScan system scan operation for multi-site applications. ProScan is a multi-site system scanning algorithm. ProScan provides the radio with the ability to select a new system for the radio to communicate on, when the selected system drops below a predefined level. This algorithm enables each radio to analyze the signal quality of its current control channel and compare it with the signal quality of the control channel for each site in its adjacent scan list. The signal quality metric used for the ProScan algorithm is based on a combination of both Received Signal Strength Indicator (RSSI) and Control Channel Verification (CCV) measurements. When the selected system degrades to a pre-programmed level, the radio will begin to look for a better control channel. Once a control channel that exceeds the pre-programmed parameters is found, the radio will change to the new system and emit a tone (if enabled through programming). If the control channel is completely lost, the radio will enter Wide Area System scanning and search the programmed adjacent systems until a suitable control channel is found. 8.21 EMERGENCY OPERATION The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency system and group, and the emergency audio and display freeze can each be enabled or disabled through programming. When an emergency is declared scanning will stop and restarts only after the emergency has been cleared. 8.21.1 Receiving an Emergency Call When receiving an Emergency Call on the selected group and system, an alert beep is heard and is displayed. The message *RXEMER* flashes in the display on line two until the emergency condition is cleared. 8.21.2 Declaring an Emergency Call Perform the following steps to send an emergency call to a selected system and group (or on an optionally pre-programmed group). 1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for approximately one second (this time is programmable and therefore could be longer or shorter; check with the system administrator). The radio will transmit an emergency call request with the radio ID until an emergency channel assignment is received. 2. When the working channel assignment is received, the radio sounds a single beep indicating the radio has auto keyed (see Table 8-4) and is ready for voice transmission. *TXEMER* flashes on line two in the display until the emergency is cleared. 3. Press PTT and speak into the microphone in a normal voice. and momentarily turn ON. 4. Release PTT when the transmission is complete. To clear the emergency, first press and hold the button. While continuing to hold the button, press the EMERGENCY button. (This will work if the radio is programmed to clear emergencies.)

MM-013994-001, Rev. Ap1 56 8.22 INDIVIDUAL CALLS 8.22.1 Receiving and Responding to an Individual Call When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the assigned working channel and displays . The first line on the display shows the logical ID number of the unit sending the message, or the associated name if the ID number is found in the individual call list. The radio can be programmed to ring when an individual call is received. If enabled, the ring begins five seconds after the caller un-keys and will continue until the PTT button, the button or the individual call mode is entered. The volume of the ring is adjustable through the volume control levels. If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call will automatically be directed to the originating unit. If a response is not made before the call-back time-out, the radio will return to normal receive display, and *WHC* will appear on the first line of the LCD. To respond after the call-back time-out, press the key. The radio's display will show the callers ID on the first line and WHCI=1 on the second line. Pressing the PTT button at this point will initiate an individual call back to the original caller. The radio stores the IDs of the last 10 callers in the Calls Received List as shown. Individual calls are stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The most recent call is stored in position 1, the second most recent call is stored in position 2, etc. Figure 8-11: Calls Received Lists To access the Calls Received List, press the key twice.

Unsuccessful interconnect signaling returns the radio to the normal receive mode and the number remains displayed until the special call is cleared or the time-out expires or another group or system is selected. 3. To terminate the call, momentarily press the button. 8.23.3 Dual-Tone Multi-Frequency: Overdial/Conventional Mode Once the radio has established a connection to the public telephone system, it may be necessary to “over-dial” more digits to access banking services, answering machines, credit card calls, or other types of systems that require Dual-Tone Multi-Frequency (DTMF) access digits. Overdial operation can also be used to initiate a telephone interconnect call via DTMF signaling if a dial tone has already been accessed on the system. This method makes a telephone interconnect call while operating in the conventional mode but will also function in trunked mode if a dial tone is directly accessible. Telephone numbers and other number sequences for overdialing can be stored in the phone list when programming the radio. These numbers are accessed by pressing the key, then following the selection mode rules. Perform the following procedures to access and dial these stored numbers. P7350 Model Radio 1.

If necessary, a pause can be entered by pressing and holding 0-9, , or until an underscore appears in the display (telephone interconnect only). The individual call list entries will accept up to 5 digits. The phone call list entries accept a combination of up to 31 digits and pauses. 4. Press and hold the key until the display changes indicating that the number has been stored. Repeat steps 1-4 to store additional numbers, to change numbers already stored, or to change the storage location of a number. 8.25 STATUS/MESSAGE OPERATION The Status and Message operations allow for the transmission of a pre-programmed status or a pre-programmed message to an EDACS site. Each Status and Message is assigned an ID then cross-referenced with the representative status condition (“Off Duty,” for example) or a message (“Call home”). In addition, Status conditions can also be associated with a programmable Menu entry (required for second method of transmitting a Status condition (see Section 8.25.1). 8.25.1 Status Operation P7370 Model Radio One of two methods can be used to transmit a status condition. METHOD 1: 1. Press the key, then use the or buttons to scroll to the pre-programmed status condition. STATUS and 0 through 9 pre-programmed status selections are available from the menu. 2. If STATUS is selected, you need to enter the number of the status condition youintend to transmit. If no status has been programmed for the selected number key,the radio will display NO ENTRY. A valid selection will display the status for a pre-programmed time. After the time-out expires or the key has been pressed (the key will override the time-out period), the status is selected and will be transmitted to the site or stored in theradio memory where it can be polled by the site at a future time. METHOD 2: 1. Press the key. 2. Press the corresponding pre-programmed 0 through 9 status condition key. If no status has been programmed for the selected number key, the radio will displayNO ENTRY. A valid selection will permit the status condition to appear in the top line of the display and the status ID to appear in the second line of the display for a pre-programmed time. After the time-out expires or the key has been pressed (the key will override the time-out period), the status is selected and will be transmitted to the site or stored in theradio memory where it can be polled by the site at a future time. View the currently selected status after it has been transmitted by pressing the key and then the key and then the button prior to the time-out period. If the status was not sent successfully to the site, the text associated with the status condition will flash in the display. The status selection can be changed by pressing a different status key 0 through 9, or the status operation can be cancelled by pressing Option Button 2 . Both operations must be carried out prior to the time-out period.

MM-013994-001, Rev. Ap1 62 8.25.2 Message Operation The following method can be used to transmit a Message using the Message Operation. 1. Press the key. 2. Press the corresponding pre-programmed 0 through 9 pre-programmed “message” key. If no message has been programmed for the selected number key, the radio will display NO ENTRY. A valid selection will permit the message to appear in the top line of the display and the message ID to appear in the second line of the display for a pre-programmed time. The message selection can be changed by pressing a different message key 0 through 9, or the message operation can be cancelled by pressing Option Button 2 . Both operations must be carried out prior to the pre-programmed time-out period. 8.26 DYNAMIC REGROUP OPERATION Dynamic Regroup Operation permits multiple talk groups (up to eight) to be added to a radio via the system manager. The radio must be pre-programmed to respond to regrouping. Dynamic regrouping will not be activated in a radio until the system manager sends an activation message. Each radio that receives and acknowledges the regrouping instructions is successfully regrouped. Pressing and holding the button for 2.5 seconds toggles the user into and out of the dynamic regroup groupset. A double beep will sound for entry or exit. The display will indicate REGRP_0x where "x" is a digit of 1 to 8 indicating the group (when dynamic regroup has been enabled by the user). If the radio is in dynamic regroup and the user selects a group that has not been regrouped, the display will show NO ENTRY. The radio will be prevented from transmitting and receiving calls in this condition except for scanned groups. After the time-out expires or the key has been pressed (the key will override the time-out period), the status is selected and will be transmitted to the site or stored in the radio memory where it can be polled by the site at a future time. 8.26.1 Emergency Operation If the pre-programmed groupset on the currently selected system contains an EMER/HOME group and the radio is in dynamic regroup, the radio will declare the emergency on the currently selected dynamic group. 8.27 MACRO KEY OPERATION Macro key operation permits the user to accomplish a series of keystrokes with a single "macro" keystroke. Each Macro Key is capable of executing up to twenty (20) keystrokes, to any push button input (i.e., keypad keys, OPTION buttons, etc.). Each macro key can be pre-programmed to activate when pressed or when released. A macro key may also be pre-programmed to change the key stroke sequence the next time the macro key is activated. For detailed operation and assignment of macro keys, contact your communications supervisor or administrator. 8.28 PORTABLE DATA The P7300 series portable radios, when operating in the EDACS Trunked configuration, permit both voice and data calls to be transmitted and received. The radio can handle only one type of call at a time;

MM-013994-001, Rev. Ap1 63 however, either data or voice is selected transparently by the operator through normal usage of the radio. Data communications is not supported in conventional mode. The radios can be connected to a Mobile Data Terminal (MDT) or to a host computer. Any RS-232 compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) may be connected to the radio. Support for MDTs or host computers is a programmable option per radio. Additionally, radios may also be programmed for data only operation (no voice calls transmitted or received). 8.28.1 Displays The following will be displayed during the various states of data mode of operation: TX DATA Appears on top line of display when the radio is transmitting a data call. RX DATA Appears on top line of display when the radio is receiving a data call. DATA OFF Appears on top line of display when the radio is in the data disabled state. DATA ON Appears for two seconds on top line of display when the radio is toggled to the data enabled state. 8.28.2 DATA OFF Operation The radio can be placed in the data disabled state by any of the following methods. When the data state is disabled, DATA OFF appears on the top line of the display. • Declaring an emergency (not to be used unless an actual emergency condition exists). Alert tone will sound. • Pressing Option Button 1 (if pre-programmed as “no data” key). Alert tone will sound. • Pressing the pre-programmed “no data” (ND) key. Refer to previous bullet. 8.28.3 DATA ON Operation The data state is enabled by one of the following (depending on how it was disabled). DATA ON will appear on the top line in the display for two seconds then the display will return to normal. • Pressing the pre-programmed “no data” (ND) key toggles data state ON or OFF. • Clearing an emergency. This is valid only if the emergency caused “DATA OFF” operation. 8.28.4 Exiting Data Calls Under normal conditions, the radio enters the scan lockout mode and returns to the control channel after completion of a data call (transmit or receive). If, during a data call, one of the following operations occurs, the data call is immediately terminated and the radio performs the desired function: • If the PTT is activated. • If an Emergency is declared by pressing the pre-programmed emergency button. • If a group or system is changed. 8.28.5 Scan Lockout Mode Following the transmission or reception of a data call, if scan is enabled, scanning will stop temporarily. There are two independent pre-programmed times associated with this mode; one after a received data

MM-013994-001, Rev. Ap1 64 call and one after a transmitted data call. During this time the scan indicator will flash to indicate that scan is enabled but temporarily suspended. This condition typically returns to normal scan operation when the pre-programmed time expires; however, the following operations and conditions will terminate the scan lockout mode before the timeout has expired. • Press the button. • Press the PTT. • Change a group or system. • Enter Telephone Interconnect mode. • Enter Individual call mode. • Receive a new emergency assignment. • Declare or clear an emergency. • Receive an individual or phone call. • Receive an Agency, Fleet, or System All Call. • Press (P7350 model) or (P7370 model) to toggle Scan ON or OFF. 8.28.6 Data Lockout Mode During the voice call scan hang time (pre-programmed) the radio does not receive data calls.

Quick Keys function as a toggle for these menu items. Table 9-6: Quick Key Sequence QUICK KEYS FUNCTION 1# Transition to ECP mode If ECP code is not loaded in the radio, “No App” appears in the display 2# Toggles Stealth Mode On/Off 3# Toggles Scan Mode On/Off (Normal/Fixed, see details below) • If the Scan Mode is Normal when the Scan Mode is toggled Off, the Scan Mode will be Normal when toggled On again. • If the Scan Mode is Fixed when the Scan Mode is toggled Off, the Scan Mode will be Fixed when scan mode is toggled On again. • If the Scan Mode is Off when the radio boots up, the Scan Mode will be Normal when Scan Mode is toggled On. 4# Lights/Tones On/Off Pressing 4# turns the TX/RX LEDs, Backlight, and Side Tones On/Off. If any of the TX/RX LEDs, Backlight, and/or Side Tones are On, and this quick key sequence is used, then all of the TX/RX LEDs, Backlight, and Side Tones are turned Off. If the radio is in Stealth mode, this quick key is disabled since the user is not able to turn on the light/tones in stealth mode. 6# XCOV & XCOV-TG Attach/Detach This quick key sequence is used to manually connect to a V-TAC. When attaching to a V-TAC, the radio’s programming determines whether to attach to the V-TAC in XCOV or XCOV-TG mode. 1. If the user attaches to a V-TAC manually, using the *61# or *62# command sequence, the radio is understood to be attached and this quick key sequence will detach the radio from the VTAC. 2. If the user detaches manually from a V-TAC using the *60# command sequence, the radio is understood to be detached and this quick key sequence will attach the radio to a VTAC. 3. At bootup, the radio is understood to be detached from a VTAC. If a radio automatically attaches to a VTAC, the radio is still understood to be detached from a VTAC and will attempt to attach to a VTAC. 4. If a radio manually attaches to a VTAC and then is automatically detached from a VTAC, the radio is still understood to be attached to a VTAC and will attempt to detach from a VTAC. 9.12 LOCK/UNLOCK THE KEYPAD 1. Press and hold the button. 2. While holding the button, press the button on the side of the radio. 9.13 DUAL-TONE MULTI-FREQUENCY (P7370 ONLY) Dual-Tone Multi-Frequency (DTMF) is the system used by touch-tone telephones. DTMF assigns a specific tone frequency to each key so a microprocessor can easily identify its activation. This allows for specific tasks such as entering a user ID and password, or selective calling.

MM-013994-001, Rev. Ap1 84 A shortened User ID number can be dialed using the following guidelines: • If the radio being called is in the same region and agency – enter only the last four digits. • If the radio being called is in the same region, but a different agency – enter the last seven digits. • If the radio being called is in another region or if the area is unknown – enter all ten digits. 2. Press PTT (and release) to ring the other user. The ring tone is sounded. If the other user accepts the call, the called user’s alias will appear in initiating caller’s display. The two are now in a unit-to-unit call until one ends the call, the call is terminated due to an initiated emergency, or the maximum time limit of ten (10) minutes is reached. If the called radio is busy, “BUSY” will appear in the second line of the display. 9.24.2 Selective Call Using Speed Dial Speed dial numbers are defined and provisioned by the OpenSky network administrator and cannot be manually entered into the radio by the user. Contact the administrator if changes to the speed dial list are required. 1. Scroll through the Menu options using the or button until “Speed Dial” appears in the second line of the display. Using the or keys, scroll through the pre-programmed speed-dial numbers until the desired number appears in the display and press the PTT button. OR 2. Press and hold a key associated with a given number for more than three seconds. For example, press and hold the to open the Speed Dial Menu and display the number assigned to that key in the speed dial list. Press the PTT button. A ring tone is sounded. If the other user accepts the call, the called user’s alias will appear in initiating caller’s display. The two are now in a unit-to-unit call until one ends the call, or the call is terminated due to an initiated emergency. If the called radio is involved in another selective call, “BUSY” will appear on the second line of the display. “Unavailable” is displayed when the call has not been answered after a 1 minute timeout or when the other party is not registered on the network. 9.24.3 Accepting a Selective Call 1. The radio will ring (like a telephone), indicating you are receiving a Selective Call. 2. Press the , or the or buttons to accept the incoming selective call. 3. “CONNECT” will appear in the display, followed by “Lim 10 Min.” “SEL CALL” and the alias of the caller appear in the display once the call is established. 9.24.4 Rejecting a Selective Call When a Selective Call is being received (the radio is ringing), you can reject the call by pressing either of the or buttons or the key, or by turning the Voice Group Selector Control knob. The call will be rejected and “Reject” appears on the callers display.

MM-013994-001, Rev. Ap1 85 9.24.5 Terminating a Selective Call Terminate a Selective Call (call must be active) by pressing the or buttons or the key, or by turning the Voice Group Selector Control knob. “HANGUP” will appear in the display followed by the active talk group. 9.25 SELECTIVE ALERTS Selective alert messaging is an OTP feature that allows one of up to eight (8) pre-programmed (canned) text messages to be sent from one radio to another. The sender specifies a destination (receiving) radio, selects one of the pre-programmed text messages, and then transmits it to the destination radio. The message delivery system adds sender and time-of-day information and forwards the message to the destination (receiving) radio. The sending radio receives a brief message noting the status of the transmission. Received messages are stored in the radio until deleted or until the radio is rebooted. Received messages do not survive a reboot. 9.25.1 Defining Messages All selective alert messages are pre-defined. The messages are programmed and provisioned remotely by your OpenSky system administrator. The radio user cannot create selective alert message content. The entire selective alert message, including the abbreviation, can be up to 200 characters long. When sending a selective alert message, the radio may display one of the following status messages (Table 9-8). Table 9-8: Status of Selective Alert Messages STATUS MESSAGE DEFINITION Delivering Select Alert message transmit attempt Busy Too busy – Try again Dest Down Receiving radio not logged on – Not registered Not Reg Transmitting radio not logged on – Not registered Delivered Transmission complete Unreachable No response Partial Transmission interrupted 9.25.2 Sending a Message The sending process has three steps. First select the destination radio’s User ID, then select the alert message, and finally send the message. 9.25.2.1 Selecting a Destination Using the Keypad (P7370 Only) 1. Using the keypad, enter *7, the keys. At the “AlertDst” prompt, enter the full User ID of the unit to send the message. A shortened User ID number can be dialed using the following guidelines: • If the radio being called is in the same region and agency – enter only the last four digits. • If the radio being called is in the same region, but a different agency – enter the last seven digits.

MM-013994-001, Rev. Ap1 86 • If the radio being called is in another region or if the area is unknown – enter all ten digits. 2. Press the key to activate the selection. 3.

MM-013994-001, Rev. Ap1 95 10 CONVENTIONAL OPERATION The radio functions in the conventional mode when using conventional communications channels (non-trunked). 10.1 CONTROLS The radio features two rotary control knobs and an emergency button mounted on the top of the radio. Push-To-Talk and option buttons are mounted on the side. The front mounted keypad has six buttons on the P7350 Scan model and 15 buttons on the P7370 System model. Figure 10-1: Top View Figure 10-2: Side View

MM-013994-001, Rev. Ap1 96 10.1.1 Buttons and Knobs This section describes the primary function of the button and knob controls. Refer to Figure 10-1 and Figure 10-2. POWER ON/OFF-VOLUME CONTROL KNOB Applies power to and adjusts the receiver’s volume. Rotating the control clockwise applies power to the radio. A single alert tone (if enabled through programming) indicates the radio is operational. Rotating the control clockwise increases the volume level. Minimum volume levels may be programmed into the radio to prevent missed calls due to a low volume setting. While adjusting the volume the display will momentarily indicate the volume level (i.e. VOL=31). The volume range is from a minimum programmed level of zero (displayed as OFF in the display) up to 40, which is the loudest level. SYSTEM/GROUP/CHANNEL CONTROL KNOB Selects pre-programmed channels. This is a 16-position rotary knob. Note: A mechanical stop, which can limit the positions accessed, is shipped with the radio but must be installed. To install the mechanical stop, remove the System/Group/Channel control knob, loosen the set screw on the System/Group/Channel control knob metal base (using a 1.27mm hex wrench), and remove the System/Group/Channel control knob metal base. Replace the 16 channel ring with the channel stop ring located at the desired channel. Re-install the System/Group/Channel control knob metal base, tighten the set screw, and re-install the System/Group/Channel control knob. EMERGENCY/HOME BUTTON Automatically selects the pre-programmed Group/System by pressing and holding for a programmed duration. It can also be used to declare an emergency by pressing and holding for a programmed duration. The button must be pre-programmed for either operation, but not both. PTT BUTTON PTT must be pressed before voice transmission begins. OPTION BUTTON Activates one of a number of programmable software options selected during PC programming. Programmable options include hi/low power settings, keypad lock, LCD contrast, and LCD and keypad back lighting. CLEAR/MONITOR BUTTON (OPTION BUTTON 2) Unsquelches the receiver and allows channel monitoring prior to transmission. Momentarily removes the Receiver Channel Guard decoding from the channel.

The voice modes are programmed on a per-group basis within each trunked system and on a per-channel basis within each conventional system. 10.17.1 Clear Mode The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice signals. These analog signals are non-digitized. Clear mode transmissions can be monitored easily by unauthorized persons. Groups or channels programmed for clear operation cannot transmit or receive digital messages.

MM-013994-001, Rev. Ap1 109 10.17.2 Digital Mode The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or inoperative. 1. If receiving an analog message trunked call, the radio responds in the analog mode during the hang time on the working channel. 2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 3. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is transmitted in the mode defined by the system mode as programmed for the current system if the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-Call mode programmed in the list for that ID. The overdial DTMF tones are not available while in the Digital Mode. 10.17.2.1 Scanned Group Calls Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same group was available in digital and entered in the scan list, it can receive clear and digital calls, provided auto-select was programmed in the radio. The user can choose to transmit on the scanned or selected group. If a group is entered in the scan list more than once under different modes (clear and digital), only the first occurrence of the group will be used.

MM-013994-001, Rev. Ap1 113 11 P25 OPERATION Once a P25 system has been selected from the available systems on your P7300 series portable radio, the characteristics described in the following sections will govern operation. 11.1 CONTROLS The radio features two rotary control knobs and an emergency button mounted on the top of the radio. Push-To-Talk and option buttons are mounted on the side. The front mounted keypad has six buttons on the P7350 Scan model and 15 buttons on the P7370 System Radio. Figure 11-1: Top View Figure 11-2: Side View

MM-013994-001, Rev. Ap1 114 11.1.1 Buttons and Knobs This section describes the primary function of the button and knob controls. Refer to Figure 11-1 and Figure 11-2. POWER ON/OFF-VOLUME CONTROL KNOB Applies power to and adjusts the receiver’s volume. Rotating the control clockwise applies power to the radio. A single alert tone (if enabled through programming) indicates the radio is operational. Rotating the control clockwise increases the volume level. Minimum volume levels may be programmed into the radio to prevent missed calls due to a low volume setting. While adjusting the volume the display will momentarily indicate the volume level (i.e. VOL=31). The volume range is from a minimum programmed level of zero (displayed as OFF in the display) up to 40, which is the loudest level. SYSTEM/GROUP/CHANNEL CONTROL KNOB Selects systems or groups/channels (depending on programming). This is a 16-position rotary knob. Note: A mechanical stop, which can limit the positions accessed, is shipped with the radio but must be installed. To install the mechanical stop, remove the System/Group/Channel control knob, loosen the set screw on the System/Group/Channel control knob metal base (using a 1.27 mm hex wrench), and remove the System/Group/Channel control knob metal base. Replace the 16 channel ring with the channel stop ring located at the desired channel. Reinstall the System/Group/Channel control knob metal base, tighten the set screw, and reinstall the System/Group/Channel control knob. EMERGENCY/HOME BUTTON Automatically selects the pre-programmed Group/System by pressing and holding for a programmed duration. It can also be used to declare an emergency by pressing and holding for a programmed duration. The button must be pre-programmed for either operation, but not both. PTT BUTTON Push-To-Talk must be pressed before voice transmission begins. In trunked mode the radio’s ID is transmitted upon depression of the PTT button. OPTION BUTTON Activates one of a number of programmable software options selected during PC programming. Programmable options include hi/low power settings, keypad lock, LCD contrast, and LCD and keypad back lighting. CLEAR/MONITOR BUTTON (OPTION BUTTON 2) Unsquelches the receiver and allows channel monitoring prior to transmission. Momentarily removes the Receiver Channel Guard decoding from the channel.

The voice modes are programmed on a per-group basis within each trunked system and on a per-channel basis within each conventional system. 11.16.1 Clear Mode The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be monitored easily by unauthorized persons.

MM-013994-001, Rev. Ap1 128 Groups or channels programmed for clear operation cannot transmit or receive digital or private messages. 11.16.2 Digital Mode The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide improved weak signal performance and cannot be easily monitored with a standard receiver. Groups programmed for digital operation transmit only digital signals. Message trunked group calls and individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or inoperative. 1. If receiving an analog message trunked call, the radio responds in the analog mode during the hang time on the working channel. 2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 3. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is transmitted in the mode defined by the system mode as programmed for the current system if the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-Call mode programmed in the list for that ID. The overdial DTMF tones are not available while in the Digital Mode. 11.16.3 Private Mode The Private Mode allows the radio to transmit encrypted messages and receive clear or private transmissions. The radio transmits private if the group is programmed for private operation and forced operation is pre-programmed. If auto-select operation is pre-programmed and the radio is in the Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang time is active, the radio transmits private. Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An individual key is automatically selected on a per-group basis according to the radio programming. Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks of 7 keys can be stored for private systems. The bank is specified per system. When operating on a group programmed for Private Mode, all transmissions are private transmissions and the radio receives clear and private signals. The status icon is displayed when the Private Mode is enabled. If the selected group is programmed for auto-select capability, the mode may be toggled between private and clear with the key, then following the selection mode rules. Radios programmed for forced private operation do not allow a change of the transmit mode. 11.16.3.1 Displaying the Currently Used Cryptographic Key Number To display the currently used Cryptographic Key Number for either the system encryption key (for special call such as individual, phone, all, agency or fleet) or the group key (for group calls), perform the following procedure: 1. Press the button. 2. Use the or button to select "DISP KEY."

MM-013994-001, Rev. Ap1 129 3. Use the or button to toggle between displaying the system key (Figure 11-11) or the group/channel key (Figure 11-12). Figure 11-11: System Encryption Key Display Figure 11-12: Group/Channel Encryption Key Display 11.16.3.2 Key Zero All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while still pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds. A series of beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been zeroed. The display will indicate KEY ZERO. If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the radio before private communications may continue. 11.16.4 Private Operation 11.16.4.1 Receiving an Encrypted Call When receiving, the radio automatically switches between clear or private operation. If the transmission being received is an encrypted transmission, it will be decrypted, the icon is displayed, the receiver will unsquelch and the message will be heard in the speaker. For this to occur, the selected group or channel must be programmed for private operation and the correct cryptographic key must be loaded into the radio. 11.16.4.2 Transmitting an Encrypted Call 1. Select the desired group or channel. 2. Place the radio in Private Mode by pressing key; then follow the selection mode rules. On a System radio, the key can be used to toggle the Private Mode ON/OFF. When Private Mode is enabled, the icon is displayed. 3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also, the Private Mode will be enabled if forced operation has been programmed in the radio. If a group is not programmed for Private Mode operation, PVT DIS will be displayed if an attempt is made to enable private transmit mode. It is not possible to operate on this group in Private Mode. If the radio does not have the correct encryption key loaded, NO KEY# will be displayed and the call will not be transmitted.

MM-013994-001, Rev. Ap1 130 4. Continue with standard transmission procedures. A Private Mode access tone will be heard when the PTT button is pressed. 11.16.4.3 Scanned Group Calls Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang time, if the radio was programmed for auto-select, it will transmit back in the same mode it received the call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same group was available in private and entered in the scan list, it can receive clear and private calls, provided auto-select was programmed in the radio. The user can select transmitting on the scanned or selected group. If a group is entered in the scan list more than once, and in different modes (clear, digital, or private), only the first occurrence of the group will be used. Table 11-7: Transmit/Receive Mode Compatibility for Digital Voice Operation GROUP PROGRAMMING (TRANSMIT) CLEAR RECEIVE DIGITAL RECEIVE PRIVATE RECEIVE CLEAR Yes No No DIGITAL Yes Yes No PRIVATE Yes No Yes* *assumes the proper cryptographic key is loaded Conventional digital or encrypted channels require Channel Guard on the channel to operate correctly.

The current status of the group is displayed for a time-out period. 3. While the status is displayed, press to delete the group from the scan list. , , or turns OFF. Any group that is not in a trunked system group scan list will show a "blank" for the time out period when it is the selected channel. 11.17.4 Nuisance Delete A group can also be deleted from the scan list, if it is not the currently selected group, by pressing the key (P7350 model) or the key (P7370 model) during scan operation while the radio is displaying the unwanted group. The group will be deleted from the system's group scan list in the same manner as if done using the steps above. Deletions done in this manner will not remain deleted if the radio is powered OFF and then powered ON. 11.18 SCANNING TRUNKED SYSTEMS The radio can be programmed with the following System Scan features. These features are automatically enabled when the radio is powered ON. A key or menu option is also defined to allow the System Scan

MM-013994-001, Rev. Ap1 133 features to be toggled during radio operation. The System Scan state will be maintained through system changes but will default to ON when the radio is powered ON. Enable/Disable via Menu Selection Press and then use the or buttons to scroll through the selections until SYS SCAN is displayed. Then press to toggle the System Scan state. The SYSC ON or SYSC OFF display message is displayed for two seconds to show the new state. Enable/Disable via Pre-Programmed Keypad Key Press the key pre-programmed to toggle System Scan and the SYSC ON or SYSC OFF display message is displayed for two seconds to show the new state. 11.18.1 Wide Area System Scanning The P7300 series radio can be programmed for Wide Area System Scan operation for roaming across mobile systems. Upon the loss of the currently selected system's control channel, radios can be programmed to automatically scan the control channels of other systems. If a new control channel is found, the radio will switch to the new system and sound an alert tone. 11.18.2 Priority System Scan The radio can also be programmed for Priority System Scan. The priority system is the desired or preferred system. While receiving the control channel of the selected system, the radio will periodically leave the selected system and search for the control channel of the priority system. This is done at a programmable rate defined by the value in the Priority Scan Time control (unless the ProScan™ algorithm is enabled, as explained in the following sections). This priority scan timer is reset each time the PTT button is pressed or when the call is received. If the priority system control channel is found, (or meets the predefined criteria <ProScan>), the radio will automatically switch to the priority system. 11.18.2.1 Enabling the Wide Area System Scan Function If the radio cannot find the control channel of the selected system and begins to wide area system scan, the radio will only scan for the priority system control channel if the priority system is in the wide area scan list. 11.18.2.2 When ProScan is Enabled The radio monitors the priority system and will switch to the priority system if the criteria defined by the controls in the ProScan Options dialog box are met. If ProScan is enabled, the rate at which the radio will scan for the priority system is defined by the System Sample Time control, located in the ProScan Options dialog box. See Section 8.20.3 for more information on ProScan. 11.18.3 ProScan The radio may be programmed for ProScan system scan operation for multi-site applications depending on the version of radio flash code. ProScan is an improved multi-site system scanning algorithm designed to replace ProSound™ scanning. ProScan provides the radio with the ability to select a new system for the radio to communicate on, when the selected system drops below a predefined level. This is accomplished by enabling each radio to analyze the signal quality of its current control channel and compares it with the signal quality of the control channel for each site in its adjacent scan list. (The signal quality metric used for the ProScan algorithm is based on a combination of both Received Signal Strength Indicator (RSSI) and Control Channel Verification (CCV) measurements.) When the selected system degrades to a pre-programmed level, the radio will begin to look for a better control channel. Once a control channel that

MM-013994-001, Rev. Ap1 134 exceeds the pre-programmed parameters is found, the radio will change to the new system and emit a tone (if enabled through programming). If the control channel is completely lost, the radio will enter Wide Area System scanning and search the programmed adjacent systems until a suitable control channel is found. 11.19 EMERGENCY OPERATION The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency system and group, and the emergency audio and display freeze can each be enabled or disabled through programming. When an emergency is declared scanning will stop and restarts only after the emergency has been cleared. 11.19.1 Receiving an Emergency Call When receiving an Emergency Call on the selected group and system, an alert beep is heard and is displayed. The message *RXEMER* flashes in the display on line two until the emergency condition is cleared. 11.19.2 Declaring an Emergency Call Perform the following steps to send an emergency call to a selected system and group (or on an optionally pre-programmed group). 1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for approximately one second (this time is programmable and therefore could be longer or shorter; check with the system administrator). The radio will transmit an emergency call request with the radio ID until an emergency channel assignment is received. 2. When the working channel assignment is received, the radio sounds a single beep indicating the radio has auto keyed (see Table 8-4) and is ready for voice transmission. *TXEMER* flashes on line two in the display until the emergency is cleared. 3. Press PTT and speak into the microphone in a normal voice. and momentarily turn ON. 4. Release PTT when the transmission is complete. To clear the emergency first press and hold the button. While continuing to hold the button, press the EMERGENCY button. (This will work if the radio is programmed to clear emergencies.) 11.20 INDIVIDUAL CALLS 11.20.1 Receiving and Responding to an Individual Call When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the assigned working channel and displays . The first line on the display shows the logical ID number of the unit sending the message, or the associated name if the ID number is found in the individual call list. The radio can be programmed to ring when an individual call is received. If enabled, the ring begins five seconds after the caller un-keys and will continue until the PTT button, the button or the individual call mode is entered. The volume of the ring is adjustable through the volume control levels.

MM-013994-001, Rev. Ap1 135 If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call will automatically be directed to the originating unit. If a response is not made before the call-back time-out, the radio will return to normal receive display, and *WHC* will appear on the first line of the LCD. To respond after the call-back time-out, press the key. The radio's display will show the callers ID on the first line and WHCI=1 on the second line. Pressing the PTT button at this point will initiate an individual call back to the original caller. The radio stores the IDs of the last 10 callers in the Calls Received List as shown. Individual calls are stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The most recent call is stored in position 1, the second most recent call is stored in position 2, etc. Figure 11-13: Calls Received Lists To access the Calls Received List, press the key twice. Use the or buttons to scroll through the list. Pressing the key will display the time elapsed since the call was received. After pressing the display will appear similar to Figure 11-14.

To terminate the call, momentarily press the button. 11.21.3 Dual-Tone Multi-Frequency: Overdial/Conventional Mode Once the radio has established a connection to the public telephone system, it may be necessary to “over-dial” more digits to access banking services, answering machines, credit card calls, or other types of systems that require Dual-Tone Multi-Frequency (DTMF) access digits. Overdial operation can also be used to initiate a telephone interconnect call via DTMF signaling if a dial tone has already been accessed on the system. This method makes a telephone interconnect call while operating in the conventional mode but will also function in trunked mode if a dial tone is directly accessible. Telephone numbers and other number sequences for overdialing can be stored in the phone list when programming the radio. These numbers are accessed by pressing the key, then following the selection mode rules. Perform the following procedures to access and dial these stored numbers. P7350 Model Radio 1.

Both operations must be carried out prior to the time-out period. 11.23.2 Message Operation The following method can be used to transmit a message using the Message Operation. 1. Press the key. 2. Press the corresponding 0 through 9 pre-programmed “message” key. If no message has been programmed for the selected number key, the radio will display NO ENTRY. A valid selection will permit the message to appear in the top line of the display and the message ID to appear in the second line of the display for a pre-programmed time. The message selection can be changed by pressing a different message key 0 through 9, or the message operation can be cancelled by pressing Option Button 2 . Both operations must be carried out prior to the pre-programmed time-out period. 11.24 MACRO KEY OPERATION Macro key operation permits the user to accomplish a series of keystrokes with a single "macro" keystroke. Each Macro Key is capable of executing up to twenty (20) keystrokes, to any push button input

MM-013994-001, Rev. Ap1 141 (i.e., keypad keys, OPTION buttons, etc.). Each macro key can be pre-programmed to activate when pressed or when released. A macro key may also be pre-programmed to change the key stroke sequence the next time the macro key is activated. For detailed operation and assignment of macro keys, contact your communications supervisor or administrator. 11.25 PORTABLE DATA The P7300 series portable radios, when operating in the EDACS Trunked configuration, permit both voice and data calls to be transmitted and received. The radio can handle only one type of call at a time; however, either data or voice is selected transparently by the operator through normal usage of the radio. Data communications is not supported in conventional mode. The radios can be connected to a Mobile Data Terminal (MDT) or to a host computer. Any RS-232 compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) may be connected to the radio. Support for MDTs or host computers is a programmable option per radio. Additionally, radios may also be programmed for data only operation (no voice calls transmitted or received). 11.25.1 Displays The following will be displayed during the various states of data mode of operation: TX DATA Appears on top line of display when the radio is transmitting a data call. RX DATA Appears on top line of display when the radio is receiving a data call. DATA OFF Appears on top line of display when the radio is in the data disabled state. DATA ON Appears for two seconds on top line of display when the radio is toggled to the dataenabled state. 11.25.2 DATA OFF Operation The radio can be placed in the data disabled state by any of the following methods. When the data state is disabled, DATA OFF appears on the top line of the display. • Declaring an emergency (not to be used unless an actual emergency condition exists). Alert tone will sound. • Pressing Option Button 1 (if pre-programmed as “no data” key). Alert tone will sound. • Pressing the pre-programmed “no data” (ND) key. Refer to previous bullet. 11.25.3 DATA ON Operation The data state is enabled by one of the following (depending on how it was disabled). DATA ON will appear on the top line in the display for two seconds then the display will return to normal. • Pressing the pre-programmed “no data” (ND) key toggles data state ON or OFF. • Clearing an emergency. This is valid only if the emergency caused “DATA OFF” operation.

MM-013994-001, Rev.
