Welcome to the OpenSky Network—CHAPTER 1 P800 User’s Manual 5 Occupational Safety Guidelines and Safety Training Information CAUTION. To ensure that your exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the guidelines below. Your P800 portable radio may transmits using the integral antenna. When the radio is ON, it receives and also sends out radio frequency (RF) signals. In 1996, the Federal Communications Commission (FCC) adopted RF exposure guidelines with safety limits for portable devices, based on the recommended limits of the National Council on Radiation Protection and Measurements (NCRP) and the American National Safety Institute (ANSI). The design of the P800 Portable Radio complies with the FCC guidelines for Occupational / Controlled exposure to RF electromagnetic fields, as measured by the specific absorption rate (SAR). To assure optimal performance and make sure human exposure to RF electromagnetic energy is within the FCC guidelines, always adhere to the following: 1. Do not hold the radio less than 1 inch from your body, especially your face, ears, or eyes, while transmitting. 2. When using the radio, angle the antenna away from your body and do not allow the antenna to touch your body during transmission. 3. The push-to-talk button should only be depressed when intending to send a voice message. 4. The radio should only be used for necessary work related communications. 5. The radio should only be used by authorized and trained personnel and should not be operated by children. 6. Do not operate your radio or replace/charge batteries in explosive atmospheres (gases, dust, fumes, etc.) or near explosive basking caps. Your radio should be turned off when installing and removing batteries.
CHAPTER 1—Advanced Radio Operations 6 P800 User’s Manual 7. Do not attempt any unauthorized modification to the radio. Changes or modifications to the radio may cause harmful interference. Service of the radio should only be performed by qualified personnel. 8. Always use M/A-COM authorized accessories (antennas, batteries, belt clips, speakers/mic, etc.). Use of unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded. The information listed above provides the user with the information needed to make him or her aware of a RF exposure, and what to do to assure that this radio operates within the FCC exposure limits of this radio.
Welcome to the OpenSky Network—CHAPTER 1 P800 User’s Manual 7 OpenSky Overview M/A-COM’s OpenSky is a suite of products implementing an integrated digital voice and data system based on the Internet Protocol. The OpenSky network is digital, but provides interoperability with analog radios, making it possible to integrate existing (legacy) equipment alongside the most sophisticated digital equipment available today. • If you’ve been issued a P800 to replace a conventional analog voice-only radio, you’ll particularly appreciate the integrated voice and data capabilities of the all-digital OpenSky Portable equipment. Internet Protocol (IP) Network OpenSky’s Wireless Private Network is changing the nature of real-time communications for large fleet mobile businesses and public safety organizations alike. IP Backbone Using Internet Protocol (IP) as a network backbone for end-to-end user applications, OpenSky integrates digital voice and packet data into a single network that provides significant performance advantages over yesterday’s uneasy alliances of independently-built radio networks trying unsuccessfully to interact. Like tuning into a channel in a conventional FM radio system, logging onto the OpenSky network with your pre-configured user profile will place you in contact with the members of a software-defined talk group consisting of the set of users you customarily have to contact.
CHAPTER 1—Advanced Radio Operations 8 P800 User’s Manual • Unlike your conventional FM radio, your P800 is a node on an Internet-Protocol (IP) network with its own unique IP address. Addressable Headers Messages intended for you (whether voice or data) are broken into packets with identifying headers, just like World Wide Web internet communications, and targeted to your specific IP address. • You can travel anywhere within your network and messages intended for your IP address will find their way across the network to your personal receiving set. This doesn’t mean your communications are traveling across the World Wide Web. Far from it. OpenSky is a private wireless Intranet that adopts the best features of IP protocol for increased communications efficiency and capacity. Integrated Voice and Data Your P800 Portable Radio is a hardware component of the OpenSky network, an integrated voice and data communications system that delivers end-to-end digital voice and data transmissions over the same wireless network to a single handheld device. Digitized Voice, Text and Graphics By converting analog voice waves to digital information before transmitting them over the network, OpenSky technology makes it possible for portable radio users to send and receive voice transmissions at the same time they receive and view data on the radio’s display screen.
Welcome to the OpenSky Network—CHAPTER 1 P800 User’s Manual 9 For complex graphics, interface a PC through your radio’s RS-232 serial port. With a P800 in your vehicle, or by your side, you’ll be able to scroll through complex instructions and driving directions displayed on an external terminal device, or view on-screen emergency warnings while at the same time carrying on conversations with dispatchers or other mobile operators in your coverage area. • With OpenSky and the P800 you’ll not only use the same device to receive data and carry on conversations, you won’t even have to switch between radio modes to do both simultaneously. RS-232 Interface For heavy data transfers or displaying graphics, your P800 is equipped with an industry-standard RS-232 interface serial port for connecting a portable PC or any of an increasing array of third-party display and key-entry devices. A data programming cable is required in order to use this feature.
CHAPTER 1—Advanced Radio Operations 10 P800 User’s Manual Multi-Agency Coverage OpenSky is scalable, and designed to accommodate a virtually unlimited number of portable devices from a single fleet, or even a complex network made up of several cooperating agencies. Examples of how OpenSky improves cooperation: • Every truck in a Carrier Company’s fleet can share one large national network. • Every cruiser in a state-wide police agency can communicate with any other cruiser, from one end of the state to the other. • Patrolmen with older analog equipment can connect seamlessly with newer digital devices over the same network. • Emergency response agencies share the same network for improved communications during a massive crisis. Promotes Interagency Cooperation See full discussions of Talk Group, User Group and User Profile elsewhere in this manual In fact, the system is best suited to multi-agency public safety networks over areas as large as an entire state: every cruiser, ambulance and fire truck and all their dispatchers and support personnel sharing voice, data, even graphics over the same network. Talk to Anyone on your Network Your personal voice profile defines who you commonly communicate with. Each user needs only one authorized radio to connect seamlessly to many independent agencies or cooperating dispatch networks.
Welcome to the OpenSky Network—CHAPTER 1 P800 User’s Manual 11 • There’s no need to monitor multiple frequencies on several pieces of equipment to maintain contact. • User talk groups connect you at all times with precisely the users you need to reach, no matter who they work for, or where they’re located within the network. Connectivity with Legacy Equipment The all-digital, end-to-end IP OpenSky Intranet even provides support for legacy equipment and protocols both digital and analog. Along with supplying voice and data to your P800 portable radio, the network will also support existing (or “legacy”) radio equipment you may still need to use during a hardware rollover. This also means you’ll be able to make radio contact with cooperating agencies on the same network, whether or not they have made the conversion to OpenSky equipment. Improved Coverage and Signal Strength Part of OpenSky’s scalability is its ability to accommodate as many base stations as your coverage area requires to provide robust voice and data transmissions wherever your route may extend within the network. Cell Sites OpenSky cell sites automatically extend coverage into otherwise hard-to-reach areas and connect back into the network. Background Roaming and Switching Automated switching takes place in the background with OpenSky, so you’ll no longer be required to scan for an open channel, or wait for an available channel, when you move through your coverage area.
CHAPTER 1—Advanced Radio Operations 12 P800 User’s Manual Instead of depending on choices from a central switching station, your radio itself constantly monitors signal strength and makes its own decision to roam to another base site for a more robust connection. Better Peak-Time Performance OpenSky’s digital trunking architecture provides enormous advantages over conventional FM operation. Conversation capacity is effectively doubled by the system’s ability to carry two voice-to-voice conversations over the same channel that was previously dedicated to just one. Software-Configured Device Your P800 is a “soft” radio. Its functions are determined by OpenSky software applications, in much the same way computer hardware can be used for different applications. Unlike older analog radios you may have used, with their hardware-based proprietary functions, your P800 converts voice waves into digital information before it transmits to the network, providing noise-free audio transmission and reception. Make any radio in the system “your radio” by logging on with your identity code. What’s more, because each user in the network has a unique identity code, you can activate your identity from any radio connected to the network. Any radio from your agency’s stockpile of radio hardware can become “your” radio and log on as part of your talk group and profile.
Welcome to the OpenSky Network—CHAPTER 1 P800 User’s Manual 13 Software Upgradeable As with computer hardware, your portable radio equipment is upgradeable each time the OpenSky software enables a new feature or operational enhancement. Communications protocols, radio features, and user profiles can be changed easily and transparently to the user, during a shift or during “sign-on” at the beginning of a new shift.
CHAPTER 1—Advanced Radio Operations 14 P800 User’s Manual Enhanced Digital Features The all-digital network and OpenSky’s digital trunking features also enable a rich array of network enhancements unthinkable over historical FM broadcast systems. Voice grouping (into talk groups, user groups, and profiles) is probably the most obvious advantage to individual users. Other essential and enhanced feature sets include: • Priority scanning • Multiple priority levels • Pre-emptive emergency calls • Late-entry calls • Autonomous roaming for wide area applications. You’ll benefit from high-quality, noise-free voice communications with enhanced speech clarity compared to analog, especially in noisy environments.

P800 User’s Manual 16
Network Organization — CHAPTER 2 P800 User’s Manual 17 Your Voice Feature Personality When you activate your radio at the beginning of a shift your unique identity code is used to sign on, your radio is assigned its IP address and “provisioned” with a radio personality that identifies other users on the network with whom you are most likely to need to communicate by voice. If you need to modify your identity code bring your P800 to your network administrator. Some users you’ll only monitor, others you’ll want to talk with during the course of your shift, just as with older analog equipment you talked over one frequency and monitored others to keep informed about the activities of users in your agency, workgroup, task force, fleet or geographic area. Profiles are assigned by your network administrator to match your communication needs. You’ll have access only to those users who fall within your profile. Your overall radio personality is organized into User Groups (talk groups and listen groups), similar to a channel in a conventional FM radio system. These user groups are then organized into Profiles (collections of up to 16 user groups), similar to banks of channels. Finally, as many as 16 profiles make up your personality. Global Voice Profile Profile 1 is known as the Global Voice Group. It is always active scanning for inbound calls. It is usually allocated to a “Fleet” operation allowing users to receive broadcast calls independently of the active profile. There can be only one active user profile at any time. Within that profile, only one user group is your talk group; the others are listen groups. So, while you have tremendous capability to establish contact with a very large number of users, you’ll need to select the profile that puts you into voice contact with the talk group you need at any time.
Network Organization — CHAPTER 2 P800 User’s Manual 18 User Groups A user group is a set of users who regularly need to communicate (all the officers in a state police barracks, for instance, or all the drivers who work a particular shift). • In conventional FM radio broadcast systems, these users work together by tuning to the same channel. • In the IP-backbone OpenSky digital network, subscribers in a user group are connected by a bit of data in the header of every voice or data packet addressed to the members of the group. With OpenSky, members of the same user group can stay in contact regardless of where they roam within the network, whether the network incorporates a single county, a state, even the entire nation. Network capacity is the only limitation on the number of users that can make up a group. Dispatchers maintain contact with all members of the group, and each user can stay in “push-to-talk” contact with the dispatcher and all the users in their talk group, even if those users are from different, inter-networked agencies. The Figure below illustrates a small user group of four P800 portable radios. Figure 1 User Group Nothing about this user group so far defines it as a talk group or a listen group. That determination is made when user groups are gathered together by the network administrator into the larger groups called profiles. Each radio assigned to an individual user
Network Organization — CHAPTER 2 P800 User’s Manual 19 Profiles A profile is a set of up to 16 user groups. All sorts of configurations are possible within this simple architecture. Police officers on the same shift might make up a profile, for instance. Within this profile, each police station within the network might be assigned a user group. So the profile would connect all the cruisers from 16 stations for an entire shift. Officers from each station would most likely be in “push-to-talk” contact with one another; all other officers on the same shift would most likely monitor the other groups for “listen-only” access to all other calls within the profile. But this is only one possible configuration. Members of a talk group are not necessarily scanning the calls of the same listen groups. A user group might just as easily include officers from several stations: a SWAT team, for example, or a special emergency task force might require the collaboration of special personnel or equipment from different police stations, or even other agencies. • In conventional FM radio broadcast systems, users with this sort of relationship would create an “ad hoc” profile by tuning to one channel for talk-group privileges and scanning an entire bank of channels to monitor the conversations of other groups. • In the IP-backbone OpenSky digital network, members of the same talk group automatically receive every voice message addressed to the group, and monitor the voice messages of every other user group in the profile. Each user in the OpenSky network can be assigned as many as 16 profiles by the network administrator. At any time during a network session, users can select the profile that suits their needs with a simple twist of the Profile Selector knob. The Active Profile Number is displayed in the radio’s menu Display and Control Area.
Network Organization — CHAPTER 2 P800 User’s Manual 20 Figure 2 ___________________________________________ User Profile User Group 1 User Group 2 User Group 3 User Group 16 . . . Talk Groups While your active profile can contain up to 16 user groups, only the primary group in any profile is your talk group. All the other user groups in your profile are listen-only groups. You’ll hear the calls from these groups but they will not hear your voice unless your user group is part of their profile. To establish voice-to-voice contact with a particular user, you’ll have to select the profile that makes that user part of your talk group. This is only possible if your network administrator has configured a talk group that contains both you and the other user. If each of you has a profile that includes the other in a talk group, you can each select the profile that puts you into “push-to-talk” contact with the other. Listen Groups All the other user groups in each of your up to 16 profiles are listen groups. See the User Profile Figure above for an illustration of how user groups are related in a profile. By adding different listen groups to your several profiles, your network administrator can change the configuration of the user groups you can monitor at any time by clicking your profile selector knob to the appropriate profile. You may only have one talk group, but that doesn’t keep you from tuning in different profiles to monitor a different “bank of channels.” Talk Group Up to 15 Listen Groups
Network Organization — CHAPTER 2 P800 User’s Manual 21 Scan Modes There are three scanning options that include: Scan none: Scanning is disabled. Scan normal: Scan all listen groups in your profile. PTT results in a response in your default talk group. Scan talk back: Scan all listen groups in your profile within a time out period. PTT results in a response in the active listen group. Radio Personality Your radio personality is a collection of up to 16 profiles. The entire personality is organized by your network administrator and is unique to your communication needs. When you activate your radio at the beginning of a shift and sign on with your unique identity code, your radio is assigned its IP address and “provisioned” with a radio personality that identifies other users on the network with whom you are most likely to need to communicate by voice. Your overall radio personality is organized into User Groups (talk groups and listen groups), similar to a channel in a conventional FM radio system. These user groups are then organized into Profiles (collections of up to 16 user groups), similar to banks of channels. Finally, as many as 16 profiles make up your personality.
Network Organization — CHAPTER 2 P800 User’s Manual 22 Figure 3 _______________________________________ Radio Personality Profile 1 (1 Talk Group and up to 15 Listen Groups) . . . Profile 2 (1 Talk Group and up to 15 Listen Groups) . . . ...Profile 16 (1 Talk Group and up to 15 Listen Groups) . . . Radio personality architecture gives you tremendous flexibility to organize your communications needs, even as conditions change. With 16 profiles you can participate in as many as 16 talk groups. Or, if you only need one talk group, you can still have up to 16 different profiles that can add more than 200 other user groups to your listen group pool, each with an almost unlimited number of subscribers. Of course, with potentially hundreds of voice calls in your profile at any time, your personality also establishes strict pre-determined priority sequences to suppress the calls that would distract you from the calls you’re more likely to need.

Getting Started — CHAPTER 3 P800 User’s Manual 27 Before Your First Shift If you’re already familiar with portable radio functions and the “profile and personality” architecture of an all-digital network, you’ll find the features and controls of your new P800 to be logically arranged and easy to understand. But if you’re new to digital radio service, and especially if you’re migrating to OpenSky from an FM analog radio environment, take some time to review the Network Organization chapter of this manual before operating your radio. In either situation you’ll want to completely familiarize yourself with the controls and indicators of your new radio before you start trying to use it on the job. In particular, you’ll want to be able to scroll your way through menu display choices and quickly select the appropriate radio profile for the changing conditions of your work day. Radio Controls Examine your radio thoroughly and familiarize yourself with the location and operation of its controls and indicators before studying their functions. The following diagrams will identify the components of your equipment one panel at a time.

Advanced Radio Operations – Chapter 6 P800 User’s Manual 69 Fine-Tuning Your Personality Access to as many as 16 profiles within your pre-determined radio personality gives you tremendous responsiveness to the changing needs of your workday. What’s more, within each profile, the flexibility of the IP-protocol OpenSky network makes it possible to fine-tune your radio’s sensitivity to incoming voice calls by changing the scanning priority of specific user groups, changing radio scanning modes and channels, even locking out the incoming voice calls of entire user groups. Prioritizing a User Group At different times during your shift you may want to change the Priority Scan Group on your radio. This determines which talk group will take precedence in the event that multiple talk groups from your scan list are simultaneously active. In the event that the Priority Scan Group is not one of multiple active talk-groups, the first active is the one that will be heard. You may use the procedure below to establish one new priority scanning group for every profile in your radio personality. There’s no ranking order in scanning priority: one group per profile is the priority group; all other groups in the same profile are “non-priority.” Priority Scan isdifferent from TalkGroup status. Even ifyou give a ListenGroup priority scanstatus, your TalkGroup is still your TalkGroup.
Advanced Radio Operations – Chapter 6 P800 User’s Manual 70  How to Assign Scan Priority to a Group 1.) Turn the Profile selector dial to the profile containing the user group you wish to prioritize. When it comes to the screen, each profile is identified by its profile number and talk group, which is also the default priority scan group. 2.) Press the right Menu button one time to access the Priority Scan menu. When you arrive, you’ll see the Priority indicator P in the Status area. 3.) Use the Selector buttons to scroll through the user groups in your active profile until you find the group you want to assign scanning priority. 4.) Stop when your new priority group appears in the display panel with the Priority Scan indicator. 5.) No further action is required. Your radio assigns priority status to the group you’ve selected and, after a short delay, returns to the default screen.  How to Undo your Priority Assignment If you’ve made a scanning priority assignment in error, or immediately change your mind, you have a few seconds to undo your selection before it takes effect. 2.) Immediately press either Menu button. 3.) Your Display panel confirms that you are back in the Priority Scan menu. 4.) Use either Select button to change your selection.

Wait approximately 10 seconds for the selection process to clear the radio, then press the right Menu button to re-enter the Priority Scan menu. Duration of Priority Assignments If you make no priority assignments during your shift, each profile selects the talk group as the priority scan group. When you use the Priority Scan menu to assign scanning priority to a new group, your assignment stays in effect until you change it or turn your radio off. Powering Off erases all scanning priority assignments and resets your radio to the defaults. Changing the Scanning Mode Three scanning modes are available for the P800, but only one can be active at any time. Changing your scanning mode changes the way your radio scans voice calls for all of the profiles in your radio personality. Your choice of scanning mode will broaden or narrow the span of your communications with all the listen groups in your profiles, but does not affect your interaction with your talk groups. Your scanning mode choice will stay in effect until you change it again; even if you turn off your radio, your current selection will be saved until your next use.

Advanced Radio Operations – Chapter 6 P800 User’s Manual 75 Network Operating Mode Your P800 operates with the OpenSky Trunked Protocol (OTP) to provide the full range of features available on your digital voice and data network. At the same time, if your agency cooperates with several others in a multi-agency network supported by OpenSky’s IP backbone, all agencies benefit from the advantages of the network architecture whether or not they’ve migrated from older analog equipment to digital OpenSky radios. Locking Out User Groups There are at least two ways to focus your voice communications by suppressing calls from listen groups in your active profile. By changing your Scanning Mode to No Scan you can block all non-emergency voice calls from the listen groups in your profile, concentrating your attention entirely on your talk group. Or, by Locking Out selected groups, you can eliminate just the non-essential communications from being heard on your radio. This allows you to focus on scanning resources on just the groups whose calls you wish to track. Lock Out will block only non-emergency calls. Emergency Alerts and the voice calls that follow the alerts will break through your Lock Out command. Groups You Can Lock Out It stands to reason that only groups in your active profile can be locked out, since they’re the only groups whose voice calls you’ll hear. The Lockout menu responds to your incoming voice call activity, loading the names of calling groups into the menu as the calls are received. If you don’t find a name you’re looking for in the Lockout menu, either it’s not in your active profile, or you haven’t received a call from that group yet in this
