P-801 User’s Manual iiOccupational Safety Guidelines and Safety TrainingInformation CAUTIONTo ensure that your exposure to RF electromagnetic energy is within theFCC allowable limits for occupational use, always adhere to the followingguidelines.Your P-801T portable radio may transmit using either an integral antenna or remotespeaker microphone/antenna. When it is ON, it receives and also sends out radiofrequency (RF) signals.In 1996, the Federal Communications commission (FCC) adopted RF exposureguidelines with safety limits for portable devices, based on the recommended limits of theNational Council on Radiation Protection and Measurements (NCRP) and the AmericanNational Safety Institute (ANSI).The design of the P-801T Portable Radio complies with the FCC guidelines forOccupational / Controlled exposure to RF electromagnetic fields, as measured by thespecific absorption rate (SAR). To assure optimal performance and make sure humanexposure to RF electromagnetic energy is within the FCC guidelines, always adhere tothe 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 allowthe antenna to touch your body during transmission.3. When using the remote speaker microphone/antenna, a separate accessoryavailable to P-801T users, do not allow the antenna portion to be less than 1 inchfrom your body, especially the face, ears, or eyes, while transmitting. Do not letthis antenna touch your body while transmitting.4. The push-to-talk button should only be depressed when intending to send a voicemessage.5. The radio should only be used for necessary work related communications.6. The radio should only be used by authorized and trained personnel and should notbe operated by children.7. Do not operate your radio or replace/charge batteries in explosive atmospheres(gases, dust, fumes, etc.) or near explosive basking caps. Your radio should beturned off when installing and removing batteries.8. Do not attempt any unauthorized modification to the radio. Changes ormodifications to the radio may cause harmful interference. Any servicing of theradio should only be performed by qualified personnel.9.

P-801 User’s Manual Page 1OpenSky OverviewOverview The P-801T Portable Radio is a key component of the OpenSky network.This section gives an overview of:• The OpenSky network, and• OpenSky features and benefits.The OpenSkynetwork The P-801T Portable Radio is a part of the OpenSky network. The OpenSkynetwork is an integrated voice and data communications system. The systemprovides a communication backbone that enables voice to be converted todigital information and then transmitted over a wireless network. Dataapplications can be used simultaneously with voice over the same network.OpenSkyfeatures andbenefitsOpenSky connects seamlessly with existing applications and providessignificant user benefits.OpenSky:• Eliminates the need to carry more than one radio to communicate missioncritical information by providing one communication system to manyusers and agencies.• Relieves radio users of the task of switching channels when moving to anew coverage area by automatically roaming between base stations.• Provides improved peak traffic performance for all voice and datainformation.• Eliminates waiting for a radio channel to be available by automaticallyswitching your radio to the best available channel.• Provides simultaneous voice and data without having to change radiomodes.• Locates users quickly and accurately with Global Positioning System(GPS) equipped radios.• Prioritizes communications, eliminating non-essential information andpreventing information overload.
P-801 User’s Manual Page 2P-801: An IntroductionIntroduction The P-801T is a "soft" radio; its function is determined by softwareapplications in much the same way that computer programs are used fordifferent functions on a personal computer. Voice communication is handleddigitally; this provides noise-free audio reception and allows for addedfeatures such as voice grouping to be supported.Operatingmodes The P-801T is a digital multi-mode radio that can operate in one of manymodes. The principle operating modes are:• OpenSky Trunked Protocol (OTP), or• OpenSky Conventional FM with Continuous Tone Coded Squelch System(CTCSS).Terms andconcepts youneed to knowBefore using the P-801T radio, you may want to become familiar with someterms and concepts relating to OpenSky voice features.Term/Concept See PageUser group 3Profile 4Talk and Listen Group 5Radio Personality 6Voice Feature Summary 7
P-801 User’s Manual Page 3Terms and ConceptsUser Groups ExplainedUser group A user group is a set of users who regularly need to communicate. There canbe any number of users in a user group. Your OpenSky networkadministration personnel establish and organize user groups.An OpenSky user group is similar to a channel in a conventional FM radiosystem.Diagram The figure below illustrates the user group concept.User group Example For a state police agency, the officers assigned to the same barracks might bein the same user group.IndividualRadioUsers
P-801 User’s Manual Page 4Profiles ExplainedProfile A profile is a set of up to 16 user groups.An OpenSky profile is similar to a bank of channels in a conventional FMradio system.Diagram The figure below illustrates the profile concept.ProfileUserGroup 1 UserGroup 2 UserGroup 3User Group 16......Example Police officers on the same shift could be in the same profile – P01. The usergroups that make up this profile might be organized by the physical locationof the police stations.The diagram below illustrates this example.P01 ProfileNorthStation EastStationSoutheastStation......SouthStation
P-801 User’s Manual Page 5Talk and Listen Groups ExplainedOverview The concept of talk and listen groups is key to understanding how the radioscans active voice calls. You can change the way your radio scans for activevoice calls.Talk group A talk group is the primary user group in a profile. This is the group of usersyou will talk with and listen to the most. The first user group in each profile isyour talk group. Listen group The rest of the 15 possible user groups in a profile are listen groups. Younormally hear the voice calls from the users in this group, but your voice doesnot transmit to them.Diagram The figure below illustrates the talk and listen group concepts.UserGroup 1UserGroup 2 UserGroup 3User Group 16......Talk Group Listen GroupsExample Police officers assigned to the North station could be in the same talk group.Officers from the North Station can listen to communications from groups ofradio users from the South, East and Southeast Stations.
P-801 User’s Manual Page 6Radio Personality ExplainedRadiopersonality The radio personality is a collection of up to 16 profiles. When you turn onyour radio, the personality is downloaded into the radio so that you haveaccess to the profiles you need.Of the 16 possible profiles, only one is active at any given time.Diagram The figure below illustrates the radio personality concept. Profile 1Profile 2Profile 3Profile 4....... Profile 16..........User Group 1UserGroup 2UserGroup 3UserGroup 16..............................Example The radio personality for a police officer could include the profiles: Profile 1,Profile 2, and Profile 3. These profiles could represent each of the shifts for aparticular police agency.
P-801 User’s Manual Page 7Voice Feature SummaryVoice featuresummary User groups contain radio users who have a common need to communicateusing the radio network. User groups are characterized as either talk groupsor listen groups.• Your talk group is the primary group of radio users that you will listenand talk to.• Listen groups contain users that you normally only listen to. You do notnormally transmit voice to users in your listen groups.Profiles are comprised of up to 16 user groups and are used to organize yourradio personality into categories defined by your network administrators.Each time you turn on your radio, you access the OpenSky network and userfeatures are loaded into your radio.
