H-7YCPD0002-0 EDITION 1 11 2 RF ENERGY EXPOSURE INFORMATION 2.1 RF ENERGY EXPOSURE AWARENESS, CONTROL INFORMATION, AND OPERATION INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTS Before using your mobile two-way radio, read this important RF energy awareness and control information and operational instructions to ensure compliance with the FCC‟s RF exposure guidelines. NOTE This radio is intended for use in occupational/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. CAUTION Changes or modifications not expressly approved by JRC could void the user's authority to operate the equipment. This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses RF energy or radio waves to send and receive calls. RF energy is one form of electromagnetic 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 standards 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 two-way radios marketed in North America are designed, manufactured, and tested to ensure they meet government established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of two-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 exposure to assure compliance with established RF exposure limits. http://www.fcc.gov/oet/rfsafety/rf-faqs.html http://www.osha.gov./SLTC/radiofrequencyradiation/index.html
H-7YCPD0002-0 EDITION 1 12 2.1.1 Federal Communications Commission Regulations Your JRC JHM-875S35J mobile two-way radio is designed and tested to comply with the FCC RF energy exposure limits for mobile two-way radios before it can be marketed in the United States. When two-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 occupational requirements. Exposure awareness can be facilitated by the use of a label directing users to specific user awareness information. Your JRC JHM-875S35J two-way radio has an RF exposure product label. Also, your JHM-875S35J Installation and Operator‟s Manuals include information and operating instructions required to control your RF exposure and to satisfy compliance requirements. 2.2 COMPLIANCE WITH RF EXPOSURE STANDARDS Your JRC JHM-875S35J mobile two-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) regarding human exposure to RF electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty factors of up to 50% talk-50% listen and is authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio antenna radiates measurable RF energy only while it is transmitting (talking), not when it is receiving (listening) or in standby mode. Your JRC JHM-875S35J mobile two-way radio complies with the following RF energy exposure standards and guidelines:  United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR §§ 2 sub-part J.  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. CAUTION Table 2-1 lists the recommended minimum lateral distance for a controlled environment and for unaware bystanders in an uncontrolled environment, from transmitting types of antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio power for mobile radios installed in a vehicle. Transmit only when unaware bystanders are at least the uncontrolled recommended minimum lateral distance away from the transmitting antenna.

H-7YCPD0002-0 EDITION 1 15 3 OPERATION SAFETY RECOMMENDATIONS 3.1 TRANSMITTER HAZARDS WARNING The operator of any mobile radio should be aware of certain hazards common to the operation of vehicular radio transmitters. A list of several possible hazards is given:  Explosive Atmospheres – Just as it is dangerous to fuel a vehicle with the motor running, similar hazards exist when operating a mobile radio. Be sure to turn the radio off while fueling a vehicle. Do not carry containers of fuel in the trunk of a vehicle if the radio is mounted in the trunk. Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn OFF your radio when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the radio or its accessories could generate sparks.  Interference to Vehicular Electronics Systems – Electronic fuel injection systems, electronic anti-skid braking systems, electronic cruise control systems, etc., are typical electronic systems that can malfunction due to the lack of protection from radio frequency energy present when transmitting. If the vehicle contains such equipment, consult the dealer and enlist their aid in determining the expected performance of electronic circuits when the radio is transmitting.  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)  Liquefied Petroleum (LP) Gas Powered Vehicles – Mobile radio installations in vehicles powered by liquefied petroleum gas with the LP gas container in the trunk or other sealed-off space within the interior of the vehicle must conform to the National Fire Protection Association standard NFPA 58 requiring:  The LP gas container and its fittings.  Outside filling connections shall be used for the LP gas container.  The LP gas container shall be vented to the outside of the vehicle.
H-7YCPD0002-0 EDITION 1 16 3.2 SAFE DRIVING RECOMMENDATIONS (Recommended by AAA)  Read the literature on the safe operation of the radio.  Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in motion.  Place calls only when the vehicle is stopped.  When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations brief.  If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and continue the call.  Whenever using a mobile radio, exercise caution.
H-7YCPD0002-0 EDITION 1 17 4 OPERATING RULES AND REGULATIONS Two-way FM radio systems must be operated in accordance with the rules and regulations of the local, regional, or national government. In the United States, the JHM-875S35J mobile radio must be operated in accordance with the rules and regulations of the Federal Communications Commission (FCC). As an operator of two-way radio equipment, you must be thoroughly familiar with the rules that apply to your particular type of radio operation. Following these rules helps eliminate confusion, assures the most efficient use of the existing radio channels, and results in a smoothly functioning radio network. When using your two-way radio, remember these rules:  It is a violation of FCC rules to interrupt any distress or emergency message. As your radio operates in much the same way as a telephone “party line,” always listen to make sure that the channel is clear before transmitting. Emergency calls have priority over all other messages. If someone is sending an emergency message – such as reporting a fire or asking for help in an accident – KEEP OFF THE AIR!  The use of profane or obscene language is prohibited by Federal law.  It is against the law to send false call letters or false distress or emergency messages. The FCC requires that you keep conversations brief and confine them to business. To save time, use coded messages whenever possible.  Using your radio to send personal messages (except in an emergency) is a violation of FCC rules. You may send only those messages that are essential for the operation of your business.  It is against Federal law to repeat or otherwise make known anything you overhear on your radio. Conversations between others sharing your channel must be regarded as confidential.  The FCC requires that you identify yourself at certain specific times by means of your call letters. Refer to the rules that apply to your particular type of operation for the proper procedure.  No changes or adjustments shall be made to the equipment except by an authorized or certified electronics technician. NOTE Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of the United States may be punishable by a fine of up to $10,000, imprisonment for up to two (2) years, or both.
H-7YCPD0002-0 EDITION 1 18 4.1 OPERATING TIPS The following conditions tend to reduce the effective range of two-way radios and should be avoided whenever possible:  Operating the radio in areas of low terrain, or while under power lines or bridges.  Obstructions such as mountains and buildings.  In areas where transmission or reception is poor, some improvement can be obtained by moving a few yards in another direction or moving to a higher elevation.
H-7YCPD0002-0 EDITION 1 19 5 PRODUCT DESCRIPTION The JHM-875S35J mobile is a state-of-the-art radio that operates seamlessly between the 800 MHz frequency band and the 700 MHz frequency band. The JHM-875S35J is designed to meet the critical communications demands of public service users and complies with MIL-STD-810F specifications. The JHM-875S35J is capable of supporting multiple operating modes, including OpenSky digital operation, P25 digital conventional mode, and conventional analog mode. The JHM-875S35J uses Time Division Multiple Access (TDMA) technology in the OpenSky mode to allow multiple users to share a single RF channel. In addition, a single RF channel can support simultaneous digital voice and data communications. The JHM-875S35J provides integrated voice and data services. Voice operation is provided using a microphone and speaker included in the radio installation kit. For data transfers, the JHM-875S35J is constructed with an industry-standard RS-232 interface serial port for connecting an optional laptop PC. A PC, not included with the JHM-875S35J, provides network connectivity through the standard serial (DCE-type) interface. The JHM-875S35J has an integrated Global Positioning System (GPS) receiver. This allows the JHM-875S35J to fully support the Automatic Vehicular Locator (AVL) for fleet management and dispatch applications. The OpenSky JHM-875S35J benefits from a flexible, software-based digital radio design. Features and user profiles are software-defined and can be reprogrammed over the air. The optional over-the-air programming feature allows communication protocols to be changed easily and added at any time.
H-7YCPD0002-0 EDITION 1 20 5.1 REMOTE CONTROL HEAD OPERATION For remote mount installations configured with a NCE-5341 control head, all normal radio operations and interfaces can be handled via the control head connected to the radio unit by a single twisted-pair connection routed through a vehicle. Up to six control units may be attached to a trunk mount radio. Each control head provides a serial access point for data and any one (only one at a time) can be connected to a data device such as a personal computer. Where multiple control heads are connected or where a dash-mount radio is installed with additional remote control heads, the following features are available from each position:  Outgoing voice calls can be initiated. Any control head can initiate a call but only one can talk at a time. All other connected control heads will hear both sides of the conversation.  Incoming and outgoing audio can be heard.

H-7YCPD0002-0 EDITION 1 23 7 OPENSKY OPERATION 7.1 NCE-5341 FRONT PANEL COMPONENTS The front panel of the control head includes a dot matrix display, controls for menu navigation, an emergency button, three pre-set buttons, a Power On-Off/Volume Control knob, and a microphone connector. Table 7-1 lists all default front panel controls and their functions. Figure 7-1: Front Panel The buttons on the front panel are backlit for operation in a low ambient light level such as nighttime operation. Some buttons also flash to provide feedback of various operating conditions. In addition, the front panel contains a light-level sensor that samples ambient light levels for automatic display and button backlight brightness adjustments. In other words, it automatically brightens the display and backlights when higher external light levels exist and it automatically dims the display and backlights during lower external light levels.
H-7YCPD0002-0 EDITION 1 24 Table 7-1: Front Panel Default Controls and Functions PART FUNCTION Power On-Off/Volume Control knob Turn knob clockwise to power on the radio and increase volume. Turn counter-clockwise to decrease volume and power off the radio. Mic Connection Connection for hand-held, hands-free, speaker-mic, or headset. If enabled through programming, the emergency button sends an emergency alert and opens voice communication on the currently selected talk group or the default emergency talk group (depending upon how the system is defined). Ambient Light Sensor Radio automatically adjusts the display and button backlight brightness level based on ambient light. Do not block this sensor. or While in the dwell display, scrolls through available talk groups. Scrolls through selections within the active menu (available talk groups, pre-programmed speed dial numbers, canned alert messages, etc.). Scrolls through available menu items.

Display Area Menu selections and messages. Network Connectivity icon. Current Volume Level icon. Volume represented numerically within the display (0 = Muted, 40 = Loudest). User may select which one of several dwell displays the radio uses. Pre-Set Buttons A, B, & C These buttons are used to store and recall user-selectable parameters such as scan mode, selected profile, selected talk group, and priority talk group. Different parameters can be stored at each of the three different pre-set buttons. Preset button C can be configured via programming to reboot the radio into a particular application mode. Contact your system administrator to determine if this feature is enabled in your radio. SCAN Not functional in OpenSky systems.
H-7YCPD0002-0 EDITION 1 25 7.2 POWER UP AND VOLUME CONTROL 7.2.1 Power Up 1. Rotate the Power On-Off/Volume Control knob clockwise to power on the radio. The display will illuminate when the radio powers up. 2. Wait for the power-up sequence to complete, which takes approximately ten (10) seconds. During this time, if enabled for auto registration, the radio is provisioned with a customized user personality designed for the user‟s specific needs by the OpenSky network administrator. 3. When provisioning is complete, the radio will display the Dwell Display. If User Login is required, the bottom line of the Dwell Display will flash the message “Pls Login.” 7.2.2 Volume Control Turn the Power On-Off/Volume Control knob clockwise to increase the volume and counter-clockwise to decrease the volume. 7.3 SELF-TEST After power-up, the JHM-875S35J radio undergoes a multi-function automatic registration procedure. As many as sixteen (16) possible radio profiles are downloaded to the radio from the network in response to the User‟s ID. 7.4 LOGIN TO THE NETWORK Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled and authorized for encryption (Section 7.27), requires a User ID and password. The User ID may be remembered from the previous log-in. (Refer to Section 0 for further details regarding log-off commands.) The password will be established before the radio is put into operation. Contact the local OpenSky network administrator for more information. NOTE If necessary, contact radio system administration personnel for log-in assistance and/or radio-specific log-in instructions.
H-7YCPD0002-0 EDITION 1 26 7.5 LOG OFF THE NETWORK Log-off is automatically performed when powering down the radio. If a user is logged in using encryption features, it is necessary to log-off when encryption is no longer required. 7.6 TURNING THE RADIO OFF To turn the radio off, rotate the Power On-Off/Volume Control knob counter-clockwise. In multiple control head installations, turning off the last powered-up control head will also automatically turn off the radio. Several user-selected radio settings (i.e., scan mode, pre-set buttons, and side tone levels) are maintained for the next operational session. At the next radio power-up, maintained settings will automatically restore, along with the network personality settings. In multiple control head installations, settings are maintained for each control head position. NOTE If power is abruptly disconnected from the radio prior to executing the correct turn-off procedure, user-selected radio settings and last-tuned channel information will be lost. This can extend the time required for the radio to register with the network upon the subsequent power-up. 7.7 MENU DISPLAY AND CONTROL AREA Following power-up, the radio display shows the default talk group (Figure 7-2). Pressing up or down with changes the display to the next available menu. In many cases, the dwell display automatically re-appears after no menu buttons are pressed for a short period of time (between 10 and 30 seconds). For some menus such as the GPS and User ID menus, this does not occur until the user presses a front panel button. When the dwell display is active, it will change dynamically to reflect the current profile, received talk group/caller ID (when available), or channel (when enabled). The radio‟s display is highly interactive. It responds in the top and bottom text lines as the user presses the menu buttons ( , and MENU) to scroll through the menu loop and the entries for each menu. Table 7-4 outlines the basic menu structure.
H-7YCPD0002-0 EDITION 1 27 Figure 7-2: Typical Display 7.8 RADIO STATUS ICONS Status Icons indicate the various operating characteristics of the radio. The icons show operating modes and conditions (see Table 7-2). The location of icons on the display may vary depending on configuration. Table 7-2: Icons and Descriptions ICON DESCRIPTION Indicates data registration. Volume bars – indicates relative volume level. 7.9 DWELL DISPLAY When not engaged in menu selection, the first two lines of the display default to the user-defined display, known as the “dwell display.” The top line indicates the currently selected talk group. The second line will display the currently selected profile, caller ID/alias 1, received talk group, and current channel name. Press the ramp control to scroll through and view one of these second line options. 1 Alias is a logical ID name such as “J_Smith.” The name corresponds to a user ID such as 003-542-0001.
H-7YCPD0002-0 EDITION 1 28 7.10 PERSONALITY As illustrated in Figure 7-3, a personality defines the profiles and talk groups available to the user. It is the structuring of a collection of profiles and privileges established by the OpenSky network administrator to provide the user with a comprehensive set of profiles to communicate effectively with the necessary talk groups or individuals. Personalities are stored on the network and downloaded over-the-air to the radio. This process is called “provisioning.” Provisioning occurs at radio power-up and at user log-in. Each personality can contain up to sixteen (16) profiles and each profile can contain up to sixteen talk groups. 7.10.1 Profiles As stated above, each profile can contain up to sixteen (16) talk groups. A profile also defines the radio‟s emergency behavior. All transmissions are made on the selected talk group (displayed on the top line of the dwell display). The user can change the selected talk group to any of the other talk groups within the profile. TG a TG b TG c TG x TG y TG z TG d TG e TG f TG a TG d TG g TG h TG i TG = Talk Group Profile 1 Profile 2 Profile 3 Figure 7-3: Personality Structure Example NOTE If Global Profile is enabled by the system administrator, the number of available talk groups to scan doubles.
H-7YCPD0002-0 EDITION 1 29 7.10.2 Talk Groups A talk group represents a set of users that regularly need to communicate with one another. There can be any number of authorized users assigned to a talk group. Talk groups are established and organized by the OpenSky network administrator. An OpenSky talk group is similar to a channel within a conventional FM radio system.
H-7YCPD0002-0 EDITION 1 30 7.11 ALERT TONES The JHM-875S35J radio also provides audible Alert Tones or “beeps” to indicate the various operating conditions (see Table 7-3). Table 7-3: JHM-875S35J OpenSky Mode Alert Tones NAME TONE DESCRIPTION Call Queued one low tone/two high tones Call queued for processing. Call Denied three short beeps Radio is out of coverage area or requested talk group is active. Grant (or Go-Ahead) single short beep Sounded when resources become available for a call request placed in the queue (if enabled) upon channel access. If the radio roams to another site while transmitting, then it will auto rekey and begin transmitting on that tower. It gives a second grant tone to let the user know they have roamed. Call Removed single long low-pitched tone Notifies the user access to the channel has been lost (out of coverage area or pre-empted by higher-priority call) Selective Alert Received four short tones Only played once to indicate a selective alert has been received. Emergency Alert Tone three long tones Sounds when an emergency alert is declared Emergency Cleared Tone one long low-pitched tone Sounds when an emergency is cleared Selective Call Ring Tone a ringing tone similar to a telephone Ringing is repeated every four seconds until the call is accepted or rejected by the radio being called or until the network drops the call if unanswered after one minute PSTN Ring Tones a single medium-pitch repeating tone Two ring tone - one generated by the radio when there is an incoming telephone call or an outgoing telephone call attempt is waiting for the telephone interconnect gateway equipment to dial the Public Switched Telephone Network (PSTN). The second ring tone sounds when the gateway equipment has dialed the number. Roam Tone Two short tones, one high-pitched and one low-pitched Sounds when the radio transitions from one radio base station site to another. Out of Range Tone three brief tones If enabled via programming, sounds at a programmable interval while the radio is in a state of persistent deactivation.

NOTE Menus will vary depending upon system programming, radio hardware, and optional configurations. 7.13 CHANGING THE ACTIVE PROFILE The radio can store up to sixteen (16) standard profiles, one of which is the currently active profile. To change the currently active profile: 1. Scroll through the menu with until “ProfileMenu” is displayed. 2. Use to scroll through the list of available profiles. 3. Profile becomes active when selected for longer than 2 seconds, when the MENU is pressed, or when the menu is changed using . 7.14 CHECKING OR CHANGING THE SELECTED TALK GROUP Each profile stored in the radio can have up to sixteen (16) talk groups. One talk group within the currently active profile is set as the “selected talk group.” For the radio user, the selected talk group is typically the focus of most voice transmissions and receptions. There are two ways to change the selected talk group: First Method: 1. Use to scroll through the menu until “TalkGrpMenu” appears on the bottom line of the display. The currently selected talk group appears in the top line of the display. 2. Use to scroll through the available list of talk groups in the active profile. This list is determined by the OpenSky network administrator. Second Method: From the dwell display, use the talk group selection knob or to scroll through the available list of talk groups in the active profile.
H-7YCPD0002-0 EDITION 1 34 7.15 ADJUSTING DISPLAY AND BUTTON BACKLIGHT BRIGHTNESS The radio uses a light sensor on the front panel to automatically adjust display brightness and button backlight brightness to ambient light conditions. The display and backlights automatically brighten at higher external light levels and automatically dim at lower external light levels. However, the “Bright Menu” gives the user some manual brightness control as follows: 1. Using , scroll through the menu until “Bright Menu” appears. 2. Use to increase or decrease brightness. Display and button backlight brightness will immediately dim or brighten. 7.16 STEALTH MODE For some users, it is important to be able to turn off the radio‟s display lights, button backlighting, volume and side tones, but not the radio traffic. For example, in covert operations, lights and sounds could inadvertently expose an otherwise unobservable radio user. For this purpose, the radio has a Stealth feature that disables the radio display light, indicator light and audible side tones. When stealth mode is on, the radio continues to scan the programmed list of talk groups and the user can key-up on the selected talk group. 7.16.1 Enabling Stealth Mode 1. Using , scroll through the menu until “StealthMenu” appears. 2. To immediately turn stealth mode on, press (+) or (-) with . 3. To turn stealth mode off, press any button on the radio‟s front panel. 7.16.2 Disabling Stealth Mode Pressing any radio button other than the mic‟s PTT button or the emergency button on front panel will immediately turn stealth mode off. For example, pressing the MENU button on the front panel will turn stealth mode off. WARNING With stealth mode on, pressing any radio button (other than the mic‟s PTT button or the emergency button) on front panel will immediately turn stealth mode off.
H-7YCPD0002-0 EDITION 1 35 7.17 ADJUSTING SIDE TONE AUDIO LEVEL The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned completely off using the “Side Menu.” For covert operations, it may be necessary to turn off side tones. For safety‟s sake, turning off the radio during covert operations is not recommended. To temporarily disable the side tones that could expose the user‟s presence and position, use the menu buttons to access the “Side Menu” and select “Off” from the menu choices. If the radio is operating properly but side tones are not heard when the menu buttons are pressed, the side tones are probably turned off. To turn them back on, access the “Side Tone” menu and select a setting other than “off.” Use the following procedure set side tone level: 1. Use to cycle through the menu until the “Side Menu” appears in the bottom line of the display. 2. Use to change to the desired level (Off, Low, Medium, and High). To turn side tones completely off, use the “Off” setting. 7.18 CHANGE OPERATING MODE 4. Use to cycle through the menu until the “Mode Menu” appears in the bottom line of the display. 5. Use to choose an available mode. Press MENU and confirm (Y/N) with and press MENU again.
H-7YCPD0002-0 EDITION 1 36 7.19 RECEIVING AND TRANSMITTING VOICE CALLS As soon as the radio completes the startup/log-on/provision/self-test sequence and registers on the OpenSky network, voice calls from talk groups in the active profile will be audible. 7.19.1 Receiving a Voice Call No action is required to receive a voice call. The display responds to incoming voice calls as follows:  When the dwell display is set to received talk group and the scan mode is Normal or Fixed: a. If the received talk group matches the selected talk group, then the alias (if available) or user id of the incoming caller is displayed. b. If the received talk group does not match the selected talk group, then the received talk group name is displayed  When the dwell display is set to received talk group and the scan mode is None: a. If the received talk group matches the selected talk group, then the alias (if available) or the user id of the incoming caller is displayed. b. If the received talk group does not match the selected talk group, then None is displayed.  When the dwell display is not set to received talk group, then there is no display indication of an incoming call. Refer to Section 7.23 for detailed information on talk group scanning. Refer to Section 7.27 for detailed information regarding sending and receiving encrypted calls. 7.19.2 Transmitting a Voice Call Transmit a voice call as follows: 1. Turn the radio on. 2. If required, log-in to the network using a user ID and password (see Section 7.4). 3. Select the desired talk group for transmitting on. 4. Press and hold the Push-to-Talk (PTT) button on the hand-held microphone, pause for a moment, and then speak normally. For maximum clarity, hold the microphone approximately 1 ½ inches from the mouth and do not shout or whisper into it. If the call is queued by the network, wait for the grant tone to sound before speaking. 5. Release the PTT button when finished speaking. Refer to Section 7.27 for detailed information regarding sending and receiving encrypted calls.
H-7YCPD0002-0 EDITION 1 37 7.20 ADJUSTING AUDIO TREBLE LEVEL The tone of received signals can be adjusted using the radio‟s “Treble Menu” as follows: 1. Use to scroll through the menu until “Treble Menu” appears. The radio‟s current treble level setting indicates in the top line of the display. There are four levels available: low, medium, medium-high and high. 2. Use to increase or decrease. 3. Press the MENU button or wait a few seconds to return to the Dwell Display.
H-7YCPD0002-0 EDITION 1 38 7.21 INTERCOM MODE The optional intercom mode gives users at multiple control heads connected to the same radio the ability to communicate with each other without transmitting over-the-air. Turn intercom mode on and off using the “INTERCOM” menu as follows: 1. Use to cycle through the available menu items until “INTERCOM” appears in the display. 2. Use to toggle between “On” and “Off.” When intercom mode is turned on:  Incoming voice calls will override intercom communications for the duration of the voice call. The radio and associated control heads will remain in intercom mode and intercom communications will resume when the voice call ends.  “TG: INTERCOM” appears in the control head‟s display when talking on the intercom. This indicates microphone audio is not sent out on the selected talk group; rather, it remains localized between the radio control positions (i.e., the control heads connected to the mobile radio).  If a call exists on the currently selected talk group when a PTT button is pressed at one of the control heads, “TG: in use” appears in the display to indicate intercom mic audio cannot preempt the call on the talk group. CAUTION A user at a radio with only one control head/front panel can turn intercom mode on. In this case, pressing the microphone‟s PTT button will not send microphone audio anywhere. 7.22 TALK GROUP LOCK OUT There are two ways of focusing voice communications by suppressing calls from talk groups in the currently active profile: 1. No Scan. By turning scan off (selecting “No Scan” via the “ScnModeMenu”), only the selected talk group is audible. 2. Lock Out. By locking out selected talk groups, the “chatter” of the locked-out talk groups cannot be heard. This focuses the user‟s scanning resources to calls only on desired talk groups. Talk group lock out is a scan-related feature. With lock out, one or more talk groups in the active profile can be temporarily disabled from being scanned. Calls are not received on locked-out talk groups. Lock out settings are not retained between profile changes or when the radio is power cycled. NOTE Lock out is a listening (receive) function and only blocks received calls on locked out talk groups. Lock out does not affect transmit capability. The above methods do not apply to recent emergency lock outs. Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice calls can be heard on the radio.
H-7YCPD0002-0 EDITION 1 39 NOTE P1 and P2 talk groups cannot be locked out. The default emergency and emergency-capable talk groups can be locked out if they are NOT in an emergency state. If a talk group is locked out and is subsequently changed to the currently selected talk group, it will automatically be unlocked by the radio so the user can hear calls on the talk group. The radio may be configured so all talk groups are automatically locked out by default. In this case, they must be manually unlocked, if desired. 7.22.1 Lock Out a Talk Group 1. Use to scroll through the menu until “LockOutMenu” appears in the bottom line of the display. The name of a talk group in the currently active profile will appear in the top line. 2. Use to scroll through the list of talk groups, if any, until the desired talk group for lock out appears in the top line of the display. 3. Press the MENU button to lockout the displayed talk group. A less than symbol (<) appears next to the talk group‟s name. 4. Repeat steps 2 and 3, as needed, to lockout additional talk groups. The dwell display will re-appear a few seconds after button presses end. While scrolling through talk groups in the active profile, the only talk groups that appear in the “LockOutMenu” are those in the active profile. 7.22.2 Unlock a Talk Group 1. Use to scroll through the menu until “LockOutMenu” appears in the bottom line of the display. The name of a talk group in the currently active profile will appear in the top line. 2. Use to scroll through the list of talk groups, if any, until the talk group desired for unlocking appears in the top line of the display. A less-than symbol (“<”) appears next to the name of a talk group that is currently locked out. 3. Press the MENU button to unlock the talk group. The less-than symbol (“<”) next to the name of the talk group disappears. The dwell display appears as soon as the radio acknowledges the selection. NOTE  Changing the active profile removes any lockouts you have made.  Turning off the radio removes any lockouts you have made.
H-7YCPD0002-0 EDITION 1 40 7.23 SCANNING Three scanning modes are available for the radio, but only one can be active at any time. Changing the scanning mode changes the way the radio scans voice calls for all of profiles in the radio personality, no matter which profile is or becomes active. As described in Table 7-5, the choice of scanning mode changes the span of communications with all the talk groups in the radio‟s profiles, but does not affect interaction with the talk groups. Table 7-5: Scan Modes SCAN MODE EXPLANATION No Scan Eliminates distractions. Full communications (transmit and receive) on selected talk group. No calls received from other talk groups. Normal (Default) The user can scan all talk groups in the active profile that are not locked out as long as there is demand on the site. Priority (P1 and P2) groups are user selectable. Receive calls from more than one talk group, if available from the current site. Allows dragging of the selected talk group, P1, P2, and default emergency talk groups to the site on which the radio is registered. (If other calls are available at the site, they also can be heard but they will not be actively dragged.) The default emergency talk group, as well as any emergency-enabled talk groups, is only dragged if it is in emergency mode. Fixed Functions the same as Normal Scan Mode except the priority groups are fixed to the selected profile‟s pre-defined P1 and P2 groups (configured via the UAS). In this mode, P1 and P2 groups CANNOT be locked out. 7.23.1 Checking or Changing Active Scan Mode The currently active scan mode does not appear in the dwell display. To check it, access “ScnModeMenu” and observe it in the top line of the display. To change the active scan mode: 1. Use to scroll through the menus until “ScnModeMenu” appears in the display. 2. Use to scroll through the scan options until the desired mode appears. See Table 7-5.
H-7YCPD0002-0 EDITION 1 41 7.23.2 Scanning Priority The following lists the scanning priority order (from highest to lowest): 1. Selected talk group in emergency state. 2. Default emergency group in emergency state. 3. Selected talk group. 4. Emergency capable group in emergency state 5. Priority 1 talk group. 6. Priority 2 talk group. 7. Other (non-priority) 7.23.2.1 Changing Scanning Priority Follow this procedure to set talk groups in the current profile as the Priority 1 or Priority 2 talk group: 1. Use to scroll through the menu until “Priority1” or “Priority2” appears in the bottom line of the display (Priority1 group has higher priority than the Priorty2 group. The talk group currently set as the priority talk group appears in the top line of the display. 2. Use to select a new priority talk group. 3. Press the MENU button to set the newly selected talk group as the priority talk group. 7.24 MAKING SELECTIVE CALLS Selective calling is a feature that allows two radio units to obtain and utilize an independent voice path for a private call. Radios can be configured to both initiate and receive selective calls or to only receive selective calls. In the OpenSky system, a source radio can be configured to initiate selective calls through a pre-programmed list in memory. This method uses the “speed dial list” set up by the OpenSky network administrator and provisioned as part of the registration process. NOTE Selective calls are terminated if an emergency is declared. The network limits selective calls to ten (10) minutes maximum.
H-7YCPD0002-0 EDITION 1 42 7.24.1 Speed Dialing a Selective Call NOTE 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 until “SpeedDial” appears in the bottom line of the display. 2. Using , scroll through the pre-programmed speed-dial numbers until the desired number appears in the display. 3. Press and release the PTT button to ring the other user. a. The ring tone is sounded. b. If the other user accepts the call, the called user‟s alias will appear in the initiating caller‟s display. The two are now in a private 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. 4. To end the call, press (-) using . 7.24.2 Receiving a Selective Call When someone calls in from another radio using the selective call function, a ring sounds in the speaker and/or headset. Press up or down using or any number key to accept an incoming Selective Call. Press the microphone‟s PTT button when speaking (transmitting) to the caller. Press (-) using to reject an incoming Selective Call. A selective call will be interrupted if an emergency is declared on a monitored talk group. 7.24.3 Terminating a Selective Call Press (-) using to terminate an incoming Selective Call.
H-7YCPD0002-0 EDITION 1 43 7.25 SELECTIVE ALERT Selective alert messaging is an OTP feature allowing one of up to eight (8) pre-programmed text messages (refer to Section 7.25.3) to be sent from one radio to another. The user specifies a destination radio‟s User ID, selects one of the pre-programmed text messages, and then transmits it to the destination radio. The message delivery system adds 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. Refer to Table 7-6 for a list of possible status messages. The first few characters of a message are part of the message text entered when the message is programmed. This programming is performed by the system or network administration personnel. Messages successfully received by the destination radio are stored until deleted or until it is power cycled. 7.25.1 Sending Selective Alert Messages The destination radio‟s User ID can be selected via the menu. 1. Using , scroll through the menu until “AlertDest” (Alert Destination) appears in the bottom line of the display. The current speed dial number scrolls on the top line. 2. Use to change to a different speed-dial number. 3. When the desired speed-dial number appears, press the MENU button to activate the selection. 4. Choose and send the message. Choosing and Sending the Message After specifying the destination radio‟s User ID (Section 7.25.1), the radio automatically allows you to choose a message. The current message scrolls across the top line of the display. To choose a message: 1. Scroll through the message list using . The next available message in the list is displayed. Pause between each arrow button press to observe the entire message as it scrolls across the top line of the display. 2. To select and send the displayed message, press the Select button. 3. The status of the sent message will be momentarily displayed (Table 7-6).

Up to eight (8) received messages are stored. If another message is received, the first (oldest) message is automatically deleted to make room for new incoming messages. Displaying Received Messages 1. Using , scroll through the menu until “AlertsRecvd” (Alerts Received) appears in the bottom line of the display. “No alerts” or the last received (newest) message appears in the display. It is preceded by the time the message was received, and the sender‟s name/alias. 2. View other received messages using . 3. To delete the message currently being viewed, press the MENU button. Deleting Received Messages To delete a received message: 1. Display the message. 2. Delete the message by pressing the MENU button. 3. Confirm the deletion by pressing the MENU button again. 7.25.3 Defining Pre-Programmed Messages All selective alert messages are pre-defined by the radio system‟s maintenance personnel. These messages are sometimes referred to as “canned” messages. Custom selective alert messages cannot be created by the radio user. The entire selective alert message, including the abbreviation, can include up to 99 text characters.
H-7YCPD0002-0 EDITION 1 45 7.26 EMERGENCY COMMUNICATIONS The JHM-875S35J mobile radio can transmit both emergency voice calls and emergency alerts over the entire network. OpenSky handles emergency calls and alerts with the highest priority. For critical voice communications, an emergency call can be raised on the default talk group or the currently selected talk group by “declaring” an emergency on the talk group. The exact talk group is determined by the currently active profile. After successfully declaring an emergency on a talk group, the declaring radio‟s microphone remains “hot” for a predetermined amount of time. In other words, the radio transmits audio for a period of time even when the microphone‟s PTT button is not pressed. An emergency talk group is provided greater priority and infinite hang-time by the radio system‟s infrastructure. Hang-time is the maximum duration of quiet time between transmissions on the talk group before the infrastructure assets are automatically taken away. Because an emergency call is handled on a talk group, it is received by all radios and consoles monitoring the talk group. An emergency alert is a data message sent by the radio to the MIS console (or any console capable of receiving it). It identifies the radio declaring the emergency, and the radio‟s location (if the radio is equipped with a GPS receiver). Voice audio is not automatically transmitted during the emergency if the administrator configures the radio for alert notification only. 7.26.1 Declaring an Emergency Call or Alert To declare an emergency call or emergency alert, press and release the orange Emergency button. This button is located just to the right of the CLEAR button; see Figure 7-1 on page 17. The emergency is raised after the Emergency Raise Delay (default is one second).  The OpenSky network administrator determines if the Emergency button is used to declare an emergency call or if it is used to declare an emergency alert. This is based upon the radio‟s currently active profile.  The OpenSky network administrator also determines if the emergency is declared on the currently selected talk group or a “default” emergency talk group. Again, this is based upon the radio‟s currently active profile. A talk group upon which an emergency is declared on is considered an “emergency talk group.”  Upon successful emergency declaration:  An emergency tone will sound in the radio‟s speaker/headset if the radio is not in stealth mode.  At the declaring radio, the Emergency button flashes red if the radio is not in stealth mode. The administrator can configure the radio to automatically transmit upon successful emergency declaration, at which point the MENU button will flash red. However, the MENU button flashing red is not a requirement for successful emergency declaration.
H-7YCPD0002-0 EDITION 1 46  On the declaring radio during an emergency call declaration, the talk group that the emergency is declared on is temporarily displayed and then the word “EMERGENCY” flashes on the second line of the display.  For an emergency alert declaration, “EMERG ALERT” appears in the bottom line of the display.  For an emergency call declaration, other radio users and/or dispatchers at consoles will hear the emergency signal, a distinctive 3-tone burst. They will also hear audio from the declaring radio‟s “hot” microphone, if any.  For an emergency alert declaration, only dispatchers at consoles will hear the emergency signal and, if any, audio from the declaring radio‟s “hot” microphone.  For an emergency call, the declaring radio‟s microphone remains “hot” for a predetermined amount of time. In other words, the radio transmits audio for a period of time even when the microphone‟s PTT button is not pressed. Audio is transmitted over the emergency talk group. When the microphone is “hot” for this initial period (typically ten seconds), simply speak into it for voice transmission. If an emergency declaration is not successful, the radio will periodically re-attempt until it is successful. During this retry period, the radio will flash “EMERG PEND” on the bottom line of the display. It will display “EMERG RETRY” for each attempt. 7.26.2 Silent Emergency When this feature is enabled and an emergency call or alert is declared by pressing the emergency button, the radio will not play a tone and will display an abbreviated emergency message (default is EBA). This feature is enabled or disabled via programming or via the menu. NOTE If the Silent Emergency feature is enabled or disabled via programming, the setting will survive power cycle. Enable/Disable selection via the menu will NOT survive power cycle and the enable/disable state will revert to the programmed setting at power up. 7.26.3 Clearing an Emergency Call or Alert NOTE Check with the system administrator to ensure that the radio is programmed to allow an emergency to be cleared. If enabled via programming, clear an emergency by: 1. Pressing and holding the CLEAR button and simultaneously pressing the emergency button. 2. After the Emergency Cleared Tone sounds, release both buttons. NOTE If the radio is in stealth mode, clearing the emergency will take the radio out of stealth mode.
H-7YCPD0002-0 EDITION 1 47 7.26.4 Receiving an Emergency Call Upon receiving an emergency call declared by another radio:  An emergency tone sounds in the radio‟s speaker/headset (three short high-pitched beeps).  “EMERGENCY” flashes in the display if the radio is not in stealth mode.  On receiving radios with the emergency talk group selected, the alias of the sending party is displayed for 5 seconds during the open-mic period, then the word “Emergency” flashes on the second line of the display and continues until the emergency state ends.  If scan mode is set to “No Scan” and the emergency was declared on the selected talk group, audio on the emergency talk group is heard in the speaker/headset. See page 30 for additional information on “No Scan” operation.  If scan mode is set to “No Scan” and the emergency was declared on a talk group other than the selected talk group, the emergency talk group (identified by an “*”) must be selected before audio on it is heard in the speaker/headset.  If scan mode is set to “Normal” and the emergency was declared on the selected talk group, the selected/emergency talk group‟s name remains in the top line of the display. Audio on the emergency talk group is heard in the speaker/headset.  If scan mode is set to “Normal” and the emergency was declared on a talk group other than the selected talk group, the emergency talk group‟s name appears in the bottom line of the display. Audio on the emergency talk group is heard in the speaker/headset.  The declaring radio's alias appears in the bottom line of the display when the emergency talk group is selected.  An emergency call can be dismissed as described in the following section. NOTE A radio declaring an emergency on a talk group has a “hot” mic time period of typically ten (10) seconds just after it declares the emergency. This time period may be adjusted by system or network administration personnel on a per radio basis. 7.26.5 Dismissing an Emergency Call NOTE An emergency is dismissed for a configurable amount of time only (default = 5 minutes). To ignore an emergency call declared by another radio user: 1. Press until “EmgDismiss” appears in the display. 2. Press until the talk group in the emergency state appears, as indicated by an asterisk (*) following the talk group‟s name. 3. Press the MENU button.
H-7YCPD0002-0 EDITION 1 48 NOTE The emergency dismiss timer is cleared when the emergency is cleared. 7.27 ENCRYPTION In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption standard published by the Federal Information Processing Service (FIPS), called Advanced Encryption Standard (AES). AES is approved by the U.S. Department of Commerce for encryption of classified materials. When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile End System (MES) (e.g., JHM-875S35J mobile radio). This form of encryption provides air-link security. Voice encryption is handled automatically. Automatic encryption is initiated through the Unified Administration Server (UAS) for a specific talk group and requires nothing from the user. 7.27.1 Automatic Encryption For automatic encryption, a network administrator will select the talk group to be encrypted at the interface to the UAS. Once the talk groups have been selected and identified as secure, credentials for key generation are generated automatically by the system and provisioned to authorized users. This process requires that authorized users login to the network and be authenticated. Encryption keys require no manual handling and are never sent “in the clear” over any network interface or air-link. If a user is engaged in a call on a talk group encrypted at the network administrator level, “Secure Call” will appear in the bottom line of the dwell display if the user is logged in to that talk group. If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display will alternate between “No Access” and the alias of the radio that is currently engaged in the secure call. 7.28 PRESET BUTTONS The front panel contains three buttons labeled A, B, and C. By holding one of these buttons down for approximately three (3) seconds, the following current information is saved to the function of that button:  Selected talk group  Selected profile  Selected priority talk group  Lockouts  Scan mode  Intercom mode
H-7YCPD0002-0 EDITION 1 49 Presets are saved and restored to/from non-volatile memory. Changing the User ID (login in as a different user) will clear the presets since they are stored on a per-user basis. Changing control heads will not recall presets for the previous control head. NOTE Preset button C can be configured via programming to reboot the radio into a particular application mode. Contact your system administrator to determine if this feature is enabled in your radio. 7.29 DYNAMIC REGROUPING Dynamic regrouping requires that the network administrator determine which radio users should be formed into an impromptu talk group to respond to particular emergency conditions. The administrator will edit the personalities of the affected radios to include an emergency profile and then page the affected radios to re-register with the network to receive their edited personalities. In response, affected radios automatically re-register to receive their edited personalities. During re-registration, subscriber equipment will default to the emergency profile selected by the administrator. 7.30 GPS COORDINATES The radio‟s current latitude and longitude coordinates may be displayed using the “GPS” menu. The following procedure assumes a GPS antenna is connected to the radio and it is receiving adequate signals from GPS satellites: 1. Press until the “GPS” menu appears in the bottom line of the display. Current GPS coordinate latitude and longitude data continuously scrolls in the top line of the display in a degrees:minutes:seconds format. 2. Use to change to another menu. NOTE If the internal GPS receiver‟s data is expired (30 minutes or more) or unavailable, the radio uses the serving base station‟s coordinates [GPS (Site) is displayed]. The GPS Menu will also indicate if the data is aged (2 minutes or more) [GPS (Aged) is displayed]

H-7YCPD0002-0 EDITION 1 51 8 P25/CONVENTIONAL COMMON OPERATION 8.1 NCE-5341 FRONT PANEL COMPONENTS The front panel of the control head includes a dot matrix display, controls for menu navigation, an emergency button, three pre-set buttons, a Power On-Off/Volume Control knob, and a microphone connector. Table 8-1 lists all default front panel controls and their functions. All functions and controls of the Scan radio operate the same as the corresponding functions and controls on the System radio. Figure 8-1: Front Panel NOTE Button function may vary depending upon system programming, radio hardware, and optional configurations. Complete the table in Section 13 if the keys have been remapped to provide new functions.
H-7YCPD0002-0 EDITION 1 52 Table 8-1: Front Panel Default Controls and Functions PART FUNCTION Power On-Off/Volume Control knob Turn knob clockwise to power on the radio and increase volume. Turn counter-clockwise to decrease volume and power off the radio. Mic Connection Connection for hand-held, hands-free, speaker-mic, or headset. The Emergency button declares an emergency if enabled through programming. Ambient Light Sensor Radio automatically adjusts the display and button backlight brightness level based on ambient light. Do not block this sensor. This rotary switch selects the systems or groups/channels, depending upon programming. This rocker type button is used to display the current SCAN status for a group/channel and then add or delete the group/channel from the system scan list. Pressing the add/delete button twice while the radio is actively receiving or three times when the radio is not receiving selects the last scanned channel (Last Scanned Channel Recall). The primary function of this rocker type button is to scroll through the System list or the Group/Channel list depending upon programming. The secondary function is to increment or decrement items within a list (phone list for example). OPTION Toggle a PC programmable feature ON and OFF. CLEAR In Conventional mode, pressing this button unmutes the receiver so activity on the selected channel can be monitored. When pressed and held for approximately 3 seconds, this button toggles conventional channel decoding (Channel Guard, Digital Channel Guard, T99) ON and OFF if programmed for the selected channel. MENU Primary function - access the menu list. This is a list of additional features that are not available directly from the keypad. Secondary function - activate a selected item within a list, similar to an enter key. SCAN Primary function - toggle scan operation on and OFF. Secondary function - toggle the keypad buttons between their primary function and their secondary function. Pre-Set buttons (A, B, & C) Used to store and recall user-selectable parameters.
H-7YCPD0002-0 EDITION 1 53 8.1.1 Primary Functions (Quick Access) The secondary function of the SCAN button is to toggle the keypad buttons between their primary function and their secondary function. When the secondary keypad is active, the SCAN button can be used to toggle the keypad buttons back to their primary function. PRIMARY is displayed when the SCAN button is used to toggle the keypad keys back to their primary functions. This provides quick access to the primary functions of the keypad. This is a programmable feature of the SCAN button only. Careful consideration should be given to possible operational conflicts before enabling this feature. Several keys on the Scan version have a secondary function. The MENU key is the SELECT secondary function with the CLEAR key remaining the same for the secondary function. 8.2 TURNING THE RADIO ON Rotate the POWER ON-OFF/VOLUME knob clockwise, out of detent to turn the radio on. A short beep (if enabled through programming) indicates the radio is ready for operation. The display indicates, if programmed, the last selected system name on line 1 and the last selected group or channel name on line 2. 8.3 SELECTION MODE RULES Many operations require selection from a list such as system, group or phone number. This selection process is handled in the same manner for all lists. The ramp control, MENU, and the CLEAR button are used during the selection process. The following example systems list is used to explain the process: NOTE The hook switch functions the same as the CLEAR key in menu modes.
H-7YCPD0002-0 EDITION 1 54 SYSTEM 1 NORTH 2 SOUTH 3 EAST 4 WEST After entering a selection mode, the following generic display format will appear: X X X X X X X X Y Y Y = Z Z Z Line 1 shows the currently selected item name (XXXXXXXX) from the list. Line 2 indicates the list (YYY) that the selection is to be made from and the number of the selected item (ZZZ) within the list. (In some cases the information on lines 1 and 2 will be exchanged.) Enter the system selection mode by using the ramp control. If SYSTEM 2 is the current selection, the display appears as follows: S O U T H S Y S = 2 Line 1 contains the current system name, SOUTH; and line 2, SYS = 2, indicates that selection is from the system list and it is the second system within the list. A new system from the list is selected by using the ramp control or by directly entering the system number with the numeric keys. The ramp control scrolls through the list in increasing and decreasing order. In the previous example, pressing up with the ramp control selects the EAST system as shown in the next display. E A S T S Y S = 3 The radio can be programmed to wrap around from one end of a list to the other end or to stop at the ends.
H-7YCPD0002-0 EDITION 1 55 8.4 FEATURE ENCRYPTION DISPLAY Feature Encryption Display is available through the menu function and, if programmed, appears in the menu as “FEATURES.” This data indicates current features programmed into the radio as well as information required to add features to the radio. Once the feature has been accessed, all normal menu functions work. The user can scroll up or down through all of the entries. Feature Encryption Display provides the ability to view, in the order displayed, the following:  Serial number ROM data - serial number of the ROM  Feature encryption data stream - used to enable features  Number Fields - defines limits  Features enabled - displays bit fields of enabled features 8.4.1 Serial Number ROM (12 Hex Digits) Example: When the user wants to enable a feature in his radio, he will need to call JRC. They will ask for the ROM serial number. The serial number shown here is for example only. 8.4.2 Feature Encryption Data Stream Example: These data streams define the features the user has enabled in his radio and are required by JRC to enable other features. The data streams shown here are for example only. Note: There are three displays: FD1, FD2, and FD3. All three are required.
H-7YCPD0002-0 EDITION 1 56 Number Fields Example: These number fields show the set limits of the of the user's radio as:  SG# XXX - Maximum number of system/groups combination available  SY# XXX - Maximum trunked system limit  CH# XXX - Maximum number of conventional channels available The user needs to know the limits of his radio before attempting to enable other features. The numbers shown here are for example only. 8.4.3 Features Enabled These numbers indicate which features are enabled. Example: Table 8-2 lists possible features available in the user's radio.

H-7YCPD0002-0 EDITION 1 58 8.5 SYSTEM/GROUP/CHANNEL SELECTION In the following description of SYSTEM/GROUP/CHANNEL SELECTION, the term group is used for both group and channel. The JHM-875S35J SYSTEM/GROUP/CHANNEL knob and the ramp control are programmable for maximum flexibility. If the SYSTEM/GROUP/CHANNEL knob is assigned to select groups, then the ramp control is assigned to select systems. If the SYSTEM/GROUP/CHANNEL knob is assigned to select systems, then the ramp control is assigned to select groups. System, group, and channel selection is the primary function for these controls. 8.5.1 System Selection Several methods, some of which depend on programming, can be used to select a new system. These procedures are presumed to be starting from the normal receive display. METHOD 1: If system selection is programmed to the SYSTEM/GROUP/CHANNEL knob, select a system by turning the SYSTEM/GROUP/CHANNEL knob to the desired system position. The display registers the new system name on line 1. If the wrap option is OFF and the knob is moved to a position greater than the number of programmed systems, the highest programmed system will remain selected. METHOD 2: If system selection is programmed as the primary function of the ramp control, select a system by pressing up or down to scroll through the system list. The display registers the new system name on line 1. 8.5.2 Group and Channel Selection Several methods, some of which depend on programming, can be used to select a new group or channel. These procedures assume starting from the normal receive display. METHOD 1: If group selection is programmed to the SYSTEM/GROUP/CHANNEL knob, select a group by turning the SYSTEM/GROUP/CHANNEL knob to the desired group. The display registers the new group name on line 2. If the wrap option is OFF and the knob is moved to a position greater than the number of programmed groups, the highest programmed group will remain selected. METHOD 2: If group selection is programmed as the primary function of the ramp control, select a group by pressing up or down, to scroll through the group list. The display registers the new group name on line 2.
H-7YCPD0002-0 EDITION 1 59 8.6 LAST SYSTEM/GROUP/CHANNEL RECALL This feature, enabled through programming, allows the user to recall the last selected system/group after an emergency or home function or system/group key function. For example, if the Home button (pre-programmed) is pressed, the radio will go to the designated Home system/group or channel. If the Home button is pressed again, the radio returns to the previous system/group or channel. At this time, the user can toggle between the Home system/group or channel and the previous system/group or channel. The operation is the same for the SG1-SG5 buttons. 8.7 DIGITAL VOICE OPERATION (PROVOICE) 8.7.1 Voice Modes Each system (trunked or conventional) in the radio is programmed for no digital voice operation (analog only) or digital voice format ProVoice. ProVoice programmed systems have three (3) different voice modes: clear (analog), digital, and private. The voice modes are programmed on a per-group basis within each trunked system and on a per-channel basis within each conventional system. A radio must be equipped with the encrypt/decrypt option before it will operate in private mode. NOTE Current ProVoice Conventional operation is for talk-around mode only. Table 8-3: Transmit/Receive Mode Compatibility for ProVoice Operation GROUP/CHANNEL PROGRAMMING (TRANSMIT) CLEAR RECEIVE DIGITAL RECEIVE PRIVATE RECEIVE CLEAR Yes No No DIGITAL Yes Yes No PRIVATE Yes No Yes 8.7.2 Clear Modes In Clear Mode, the radio transmits and receives only clear (analog) voice signals. These analog signals are non-digitized and non-encrypted. Clear Mode transmissions can easily be monitored by unauthorized persons. Groups or channels programmed for clear operation cannot transmit or receive unencrypted digital or private messages.
H-7YCPD0002-0 EDITION 1 60 8.7.3 ProVoice Digital Mode ProVoice digital mode allows the radio to transmit and receive digitized voice signals. These digital signals provide improved weak signal performance and they cannot be easily monitored with a standard receiver. Groups and channels programmed for ProVoice digital operation transmit only digital signals. Private calls cannot be received or transmitted when the radio is in ProVoice digital mode because the radio does not know the cryptographic key used. Message trunked group calls and individual calls will be answered back in the mode they were received, assuming the call or hang time is still active. Individual, all and emergency calls will be transmitted clear if digital mode is disabled or inoperative.  If receiving an analog message trunked call, the radio will respond in analog mode during the hang time on the working channel.  If receiving an analog I-Call, the radio will respond in analog mode during the hang time.  When using the "WHC" feature to respond to an I-Call (after the hang time has expired), the call will be 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 will be transmitted as defined by the I-Call mode programmed in the list for that ID. ERROR Messages If any of the following error messages are displayed, the radio was either programmed incorrectly or needs servicing: DSP ERR ERR=xxxx DSP ERR DIGV ERR Power Up Only If the ProVoice circuit board is not responding, correctly, one of the following error messages will be displayed and the radio needs servicing: HARDWARE ERR= 3X 3X will be a number between 30 and 38
H-7YCPD0002-0 EDITION 1 61 8.7.4 ProVoice Private Mode ProVoice private mode allows the radio to transmit encrypted messages and receive clear or private transmissions. The radio will transmit private if the group/channel is programmed for private operation and forced operation is pre-programmed. If the radio was pre-programmed for auto-select, the radio will transmit in the following modes;  If Private mode is enabled, transmissions are always in private mode.  If Private mode is disabled and a private call is received, the Reply transmission will be in Private mode if the transmission is made during the scan hangtime. If the reply transmission occurs after the scan hangtime, the transmission will be in Clear mode. When operating on a group or channel programmed for private mode, all transmissions will be private transmissions and the radio will receive clear and private signals. If the selected group or channel is programmed for auto-select capability, the mode can be toggled between private and clear with the OPTION button. Radios programmed for forced private operation do not allow a change of the transmit mode; therefore, the OPTION has no effect. 8.7.4.1 Displaying the Currently Used Cryptographic Key Number To display the cryptographic key currently in use 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 (Not Available on Conventional radios): 1. Press the MENU button. 2. Use to select DISP KEY. Then press the MENU button. 3. Then use to toggle between displaying the system key or the group/channel key. Table 8-4: Current Cryptographic Key Display ENCRYPTION KEY DISPLAYED MESSAGE DISPLAYED System "SYS KEY" "KEY = 1" Group/Channel "GRP KEY"/"CHN KEY" "KEY = 2"/KEY = 2"
H-7YCPD0002-0 EDITION 1 62 8.7.4.2 Key Zero All cryptographic keys can be zeroed (erased from radio memory) by pressing the CLEAR and while still pressing this button, press and hold the OPTION. Press both buttons for 2 seconds. A series of warning beeps will begin at the start of this 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 Key Loader into the radio before private communications can continue. (Refer to Key Manager TQS3416 Administration and Software Release Notes for further information.) 8.7.5 Private Operation 8.7.5.1 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 receiver will unsquelch and the message will be heard in the speaker. The selected group or channel must be programmed for private operation and the correct cryptographic key must be loaded into the radio for this to occur. 8.7.5.2 Transmitting an Encrypted Call 1. Select the desired group or channel. 2. Place the radio in private mode by pressing the OPTION. If the last state of the radio was private mode, the private mode will be enabled on power up. In addition, 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 is programmed for forced private transmit operation, FRCD PVT will be displayed if an attempt is made to disable private transmit mode. It is not possible to transmit on this group/channel in clear mode. If the radio does not have the correct encryption key loaded, NO KEY # will be displayed and the call will not be transmitted. 3. Continue with standard transmission procedures. A private mode access tone will be heard when the PTT button is pressed.
H-7YCPD0002-0 EDITION 1 63 8.7.5.3 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 in different modes (clear, digital, private), only the first occurrence of the group will be used. 8.7.6 Conventional Operation 8.7.6.1 Outside Address The same outside address (works similar to Channel Guard operation) must be programmed in the transmitting and receiving radios when ProVoice digital or private operation is enabled. If address is not correct, the radios will not communicate. 8.7.6.2 Channel Guard Channel Guard encode is transmitted on analog clear channels only. Channel Guard decode will operate on either a clear or private channel. The exception is when G-STAR signaling is used (see G-STAR paragraph). 8.7.6.3 G-STAR When G-STAR is programmed on a private channel, the radio will transmit G-STAR in clear mode and then switch to private for the voice portion of the call. If G-STAR is sent with Channel Guard, then both are sent in clear mode and the radio switches to private mode. Emergency G-STAR data burst is transmitted in clear mode. 8.8 MACRO KEY OPERATION Macro key operation permits the user to accomplish a series of keystrokes with a single "macro" keystroke. Up to ten (10) macro keys can be defined, each capable of executing up to twenty (20) keystrokes, to any pushbutton input (i.e., keypad keys, buttons, etc.). Each macro key can be pre-programmed to activate when pressed or when released. A macro key can also be pre-programmed to change the keystroke sequence the next time the macro key is activated. For detail operation and assignment of macro keys, contact your communications supervisor or administrator.

Turn the radio on by rotating the POWER ON-OFF/VOLUME knob clockwise (out of detent). A short alert signal (if enabled through programming) indicates the radio is ready to use. 2. Adjust the POWER ON-OFF/VOLUME knob to the desired volume level. 3. Select the desired conventional system and channel. The display indicates the current conventional system and channel names. 4. The radio is now ready to receive calls. 5. When the radio receives a call (and the correct encoding is decoded, if programmed and enabled), it unmutes on the channel and the BSY indicator comes on. 9.6 SENDING A CALL 1. Turn ON the radio and set the POWER ON-OFF/VOLUME knob to the desired volume level. Select the desired conventional system and channel. 2. Ensure that the channel is not busy by pressing the CLEAR button to briefly disable any channel decoding and unmute the receiver or observe the unlit BSY indicator. If the Channel Busy Lockout feature is programmed for the selected channel, the radio will not transmit when the channel is busy. 3. Press and hold the PTT button. The TX indicator will turn on and a short beep sounds (if programmed) indicating that communication can begin. 4. Hold the microphone approximately three inches from the mouth and speak in a normal voice. 5. Release the PTT button when the transmission is complete and listen for a reply.
H-7YCPD0002-0 EDITION 1 74 9.7 EMERGENCY OPERATION If enabled, G-STAR emergency signaling can be transmitted when operating in the conventional mode. This G-STAR signaling will transmit 5 times with a delay between each transmission. To send an emergency call on the selected conventional system and channel (or on an optionally pre-programmed conventional emergency system and channel), proceed as follows: Press and hold the red Emergency button for approximately one second (this time is programmable and, therefore, could be longer or shorter; check with the system administrator). The radio turns on the TX indicator and proceeds to transmit the pre-programmed G-STAR emergency signaling sequence. G-STAR is programmed to transmit in one of the following methods: METHOD 1: G-STAR is transmitted on the selected channel. If the channel is changed the emergency signaling will continue to be transmitted on the newly selected channel. METHOD 2: Same as METHOD 1 but the radio will lock on to the currently selected channel. Any attempts to change the system or channel will be disabled. METHOD 3: G-STAR is transmitted on a pre-programmed conventional emergency system and channel regardless of the selected channel. In this case the selected channel is available for voice transmission and the radio will periodically change to the pre-programmed emergency system and channel to send the emergency signaling and then change back to the selected channel. METHOD 4: Same as METHOD 3 but the radio will lock on to the pre-programmed emergency system and channel. Any attempts to change the system or channel will be disabled. The emergency state can be cleared by turning the radio OFF and then back ON. 9.7.1 Using 5-Tone Signaling to Declare an Emergency If 5-Tone signaling is defined for emergency declaration in place of G-STAR emergency signaling, a pre-programmed tone sequence will be transmitted instead of the G-STAR sequence. This emergency declaration functions as the G-STAR emergency in all other respects.
H-7YCPD0002-0 EDITION 1 75 9.7.2 Tone Encode Transmission In conventional mode, two keys can be defined to be tone encode triggers. If either one of the pre-programmed tone encode triggers is pressed, a pre-programmed tone sequence will be transmitted on the current system and channel. (See Section 9.7 if the emergency key is used.) The TX indicator will light during tone transmission and a beep will sound at the end of the transmission. If enabled, audible side tones will be heard in the radio speaker as well. If PTT is pre-programmed as one of the triggers, the microphone will become active for voice communication after the tone sequence is complete. Tone encode will be transmitted with Channel Guard if one is defined, and tones are always transmitted in clear voice mode, even if the channel is set for digital or private (see VOICE MODES). Digital or private voice transmission will resume normally after the tone transmission. 9.8 SCANNING CONVENTIONAL CHANNELS Channels, which have been previously added to the scan list on a per system basis, can be scanned. The selected channel is scanned (if enabled through programming) whether or not it is in the scan list. Each conventional system's channel scan list is retained in memory when the radio is turned OFF. The scan rate will vary depending upon the number of channels in the scan list and whether or not the radio is programmed to scan for channels with decoding enabled. Fewer channels will result in a faster scan rate. If programmed for dual-priority scan operation, the priority-one, priority-two and the remaining scan list channels are scanned. Once a signal is detected and the correct encoded squelch signal is decoded (if programmed), the radio receives the message and displays the received scan channel. At the same time, scanning continues on the priority-one and priority-two channels. If a priority-one or priority-two channel carrier, regardless of encoded squelch decoding, is detected while a non-priority channel is being received, the display name is updated and the received channel is switched to the priority channel. Scanning of the priority-one channel will continue if a message is being received on the priority-two channel. While receiving a call on a non-priority or a priority two channel, the radio periodically checks the priority one and two channels. If Scan with Channel Guard is enabled, the radio will use Channel Guard to decide whether to unmute on a priority channel. The radio will stop, on squelch detection, on a priority channel. In normal operation, the radio will unmute only on detecting the correct Channel Guard; otherwise, it will remain muted until the priority channel call and hang time have ended. An optional feature allows the radio to continue scanning upon the detection of the wrong Channel Guard on a priority channel. The user can then select the rate at which this channel is scanned until the call ends.
H-7YCPD0002-0 EDITION 1 76 9.8.1 Adding Channels to a Scan List 1. With scan operation turned OFF, select the desired channel to add to the selected conventional system channel scan list. 2. Press (+) or (-) with to display the current scan status on line 1 of the display for a time-out period. 3. While current scan status is displayed, press (+) to add the channel to the scan list. is displayed. This sets the selected channel for non-priority scanning. 4. Press (+) again to set the channel for Priority 2 (P2) scanning and is displayed. 5. A third press of (+) sets the channel for Priority 1 (P1) scanning and is displayed on line 1. If the P1 or P2 channels are already set and a new channel is then assigned as the P1 or P2 channel, the previously assigned priority channel will change to non-priority scanning. The priority setting selection sequence is set and stops at P1, therefore the channel must be deleted from the scan list by pressing (-) before the channel is set to a previous priority setting. Any channel that is in a system's channel scan list will show , , or when it is the selected channel. 9.8.2 Deleting Channels From A Scan List 1. With scan operation turned OFF select the desired channel to delete from the selected conventional system's channel scan list. 2. Press (+) or (-) with . The current status is displayed for a time-out period. Press - with to delete the channel from the scan list. , , or will turn OFF. 9.8.3 Nuisance Delete A channel can also be deleted from the scan list, if it is not the currently selected channel, by pressing down with twice during scan operation while the radio is displaying the unwanted channel. The channel will be deleted from the conventional system's channel 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 turned OFF and then back ON.
H-7YCPD0002-0 EDITION 1 77 9.9 TURNING SCAN ON 1. Toggle the scan operation ON by pressing SCAN. The SCAN indicator will turn ON when the radio is scanning. NOTE Scanning will stop while the microphone is off-hook if the hook switch feature is enabled through programming. 2. When a channel on the scan list receives a channel assignment, the radio unmutes on the assigned channel, BSY indicator comes ON and the received scan channel is displayed.  The radio will continue scanning if a new channel is selected when scan is ON.  Pressing the PTT button when scan is ON will cause the radio to transmit on the displayed channel or to the currently selected channel depending on programming.  Pressing (+) with when scan is ON causes the radio to recall the scanned channel that was last received. This channel is recalled for a period equal to the scan hang time. 9.10 TURNING SCAN OFF Toggle the scan operation OFF by pressing SCAN. The radio will resume operation on the selected channel. 9.11 SQUELCH ADJUST In the conventional mode of operation, the squelch can be re-adjusted in the MENU selection mode or from a front panel key on the keypad that has been pre-programmed. A default value of 9, or any user level between 1 and 16, can be selected using programming software. The user can change this setting either of two ways from the front panel keys. NOTE A value of 16 requires a strong signal to open squelch, a value of 2 requires a very weak signal to open squelch, and a value of 1 is open squelch. NOTE When the squelch adjust feature is activated, Channel Guard, T99 decode, and Scan are disabled. When the squelch adjust feature is exited, Channel Guard, T99 decode, and Scan are restored to their previous states.

H-7YCPD0002-0 EDITION 1 79 9.12 TYPE 99 DECODE If the Type 99 Decode Option has been pre-programmed, individual selective calling is possible. The radio can now decode individual, group or supergroup paging calls. Two sets of Type 99 paging codes must be pre-programmed into the radio. When the radio decodes an appropriate Type 99 code sequence, an alert tone and visual indicator is provided to the user. The receiver then operates as a noise squelched unit until Type 99 is reset. Type 99 decode continues to operate during this noise squelched period. The appropriate Type 99 alert tone will sound again if it detects a valid two-tone sequence. Type 99 operation can be reset manually or automatically (pre-programmed). Manual reset is achieved by briefly pressing CLEAR, if programmed. Automatic reset, if enabled, occurs after a 30 second interval following the most recent decode of a Type 99 tone sequence. Hook switch (pre-programmed) can also enable or disable Type 99 decode. The pre-programmed key light will blink when Type 99 is disabled by the hook switch. Type 99 decode will continue to be active while the radio's CLEAR button is pressed. This allows the user to monitor calls and still be alerted when a call is directed to the user. While the user continues to press CLEAR, the user will hear both calls and all Type 99 tone signals. If CLEAR is pressed for longer than two (2) seconds, Type 99 decode will either be disabled or re-enabled depending upon its present state. To check the Type 99 enable status, press the Scan Add/Delete ramp control. The current status of Type 99 decode will be displayed for a time-out period. If a Horn Alert Option is installed and enabled with the Type 99 Decode Option, the radio can beep the vehicle horn when a Type 99 call is received. This option permits alerting persons out of the vehicle when a call is received. NOTE Type 99 is automatically disabled when Scan is enabled. 9.12.1 Menu Selection Press MENU and then use the ramp control to scroll through the selections until T99 ENAB is displayed.
