ECP3128A M7100 System Mobile Radio Users Guide for York County, PA Emergency Services Training Session Notes
ECP3128Apage 2 Introducing the M7100 The M7100 is multi-mode mobile radio designed to operate in a challenging public safety environment. We will learn about its operation by: –Discussing the RF system. –Learning about the parts of the mobile installation. –Name the parts of the control unit. –Originate and receive calls. –Change user parameters. –Become aware of limitations.
ECP3128Apage 3 Project 25 (P25) Project 25 is a public safety communications standard dedicated to ensuring interoperability in communications. It is designed to ensure fast and secure communications between local, state and federal agencies when protecting the public's welfare. The Project 25 standard organization is comprised of the Association of Public Safety Communications Officials (APCO), the National Association of State Telecommunications Directors (NASTD) and the U.S. Federal Government. The Federal Government through the National Telecommunications and Information Administration (NTIA) has dictated that all new and existing federal communications systems will be P25 compliant. P25 is an all digital voice system that can be trunking or conventional non-trunking.
ECP3128Apage 4 Conventional vs. Trunked System Selects which Repeater to Use Trunked Approach Channel 1 Channel 2 Group A Group B Group C Group D Conventional Approach Users Select which Repeater to Use Group A Group B Group C Group D
ECP3128Apage 5 Why Trunking? Trunking: –Improves spectral efficiency –Relieves the user from managing the channel –Encourages cross agency / shared communications –Establishes communications privacy –Encourages private communications –Discourages eavesdropping by scanners –Establishes queuing rather than waiting –Enables priority use during busy times
ECP3128Apage 6 P25 Trunking System Features Digital Control Channel Multiple Working Channels < 0.5 Second Access Group & Individual Voice Calls Unit ID for each radio Late / Delayed Entry Emergency Calls Queuing with Priority Unit Enable / Disable Wide Area Coverage
ECP3128Apage 7 ??? How Far Does it Cover ? Many factors affect range: –Site Location –Urban Clutter –Reflections / Multipath –Ducting over Water –Heavy vegetation –Weather –Frequency
ECP3128Apage 8 Simulcast – Extending the Coverage SIMULtaneous broadCAST All RF sites have: –Same number of channels –Same radio frequencies –Same channel designated as control channel When someone makes a call, that call is rebroadcast to every site regardless of whether or not someone is there to listen. The users have no indication that simulcasting is occurring other than better coverage.
ECP3128Apage 9 Multisite – Extending Coverage Units inform the network of their location: –Each time the Radio is powered up. –Each time a System selection is made. –Each time a Group selection is made. When Radio detects a high bit error rate on the Control Channel –Radio will look for another site using an algorithm. –Automatically switches to new site when criteria is met. RF Site 1 RF Site 2
ECP3128Apage 10 Radio Nomenclature Before actually operating the radio, one should know some of the terms and descriptions associated with operation. Such as: –Radio –Microphone –Speaker –Control Unit Display Buttons Knobs –Antenna Lets take a look at these before actually operating the radio.
ECP3128Apage 11 Mounting The M7100 has several mounting configurations that could apply to you. –Front Mount – radio and control is mounted together near the operator. –Remote Mount – the radio is mounted remotely (trunk) and the control unit is near the operator. –Dual Control – Two control units controlling one radio. Operation is using the control unit.
ECP3128Apage 12 Operator Position Control Unit has most of the controls for the radio. The removable microphone provides voice input as well as the Push To Talk switch. Speaker is located near the control unit. Programming or mobile data connector may be visible. Military Style Microphone Programming Interface May not be installed! Speaker

ECP3128Apage 33 Transmitter Hazards 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: ) 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.
ECP3128Apage 34 RF Energy Exposure Awareness RF Energy Exposure Information is printed in the operators manual. The user is expected to read and be aware of this information. The antenna should be installed on the outside of the vehicle in such a way to minimize RF exposure to the driver and passengers. Keep away from the antenna when transmitting and report any missing or loose antennas or cables. For bystanders unaware of the transmitter, a save distance for your band and power would be approximately 3 feet. The distance is less (half) when you are aware of the transmitter and can govern your actions.
ECP3128Apage 35 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.
ECP3128Apage 36 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 M7100IP Series 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: –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. (The P25 system sends the call sign!)
ECP3128Apage 37 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.
