This operator’s manual contains detailed operating procedures for the Select, Scan and System model radios. OPERATING TIPS Antenna location and condition is important when using a VHF radio. Operating the radio in low areas of terrain, under power lines or bridges, inside of a vehicle or in a metal or steel framed building can severely reduce the range of the unit Mountains and buildings can also reduce the range of the unit. In areas where transmission or reception is poor, some improvement maybe obtained by insuring that the antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also improve communication. Vehicular operation can be aided with the use of an externally mounted antenna. Battery condition is another critical factor in the trouble free operation of a portable radio. Observe the procedures listed in the Service Section to insure the battery packs do not develop the "Memory Effect". Always observe all of the Federal Communication Commission’s rules and regulations during any service or operating procedure. INTRINSICALLY SAFE USAGE Selected portable radios with appropriate factory installed F4 Options are certified as Intrinsically Safe by the Factory Mutual Research Corporation. Intrinsically Safe approval includes Class I, II, III, Division 1 hazardous locations in the presence of Groups C, D, E, F and G atmospheres. Non-Incendive approval includes Class I, Division 2 hazardous locations in the presence of Groups A, B, C and D atmospheres. Hazardous locations are defined in the National Electrical Code. Useful standards NFPA 437A and NFPA 437M for the classifications of hazardous areas can be ordered from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269. BATTERY PACKS Only battery packs identified with a green latch shall be used with a portable radio that is rated and labeled as Factory Mutual Intrinsically Safe. Use of non-specified battery packs voids Factory Mutual approval. The following battery pack options are approved for use in intrinsically safe ra dios: PAPA1F Rechargeable Battery Pack, Extra High Capacity (Tall Case) PAPA1G Rechargeable Battery Pack, High Capacity (Short Case) ACCESSORIES The accessories that follow are approved for use with intrinsically safe radios. Use of accessories other than those listed voids Factory Mutual approval. PAAC1J Earpiece Kit PAAE3E Speaker/Microphone PAAE 3G Speaker/Microphone/Antenna PANC1B Antenna, 136 - 151 MHz, Helical PANC1C Antenna, 146 - 162 MHz, Helical PANC1D Antenna, 157 - 174 MHz, Helical LBI-38378D PAHC1C Belt Clip PAHC1D Swivel Mount with Belt Loop PAHC5N Case, Leather, with Belt Loop (Short Case) PAHC1F Case, Leather, with Belt Loop (Tall Case) PAHC1K Shoulder Strap, Leather, with Mounting Plate PAHC5R Holster, Plastic. MAINTENANCE The M-PA radio is a very reliable unit and will normally provide many years of trouble-free service. The recommended Preventive Maintenance procedures that follow should be performed when a technician comes in contact with a unit. Component level troubleshooting information is contained in the Service Section. PREVENTIVE MAINTENANCE Antenna The antenna and antenna contact should be kept clean and free from dirt or corrosion. If the antenna contact should become dirty or corroded, communication range could be reduced. Battery Packs Insure the battery packs are properly maintained. Do not over or under charge them on a regular basis. Verify the contacts are clean and free of corrosion. Mechanical Since portable radio units are subject to shock and vibration, check for loose plugs, knobs, screws, etc. Transmitter Check Check transmit frequency and deviation. Normally these checks are made when the unit is first put into operation. They should be repeated after the first month of operation, then annually. Receiver Check Receiver sensitivity should be checked periodically as an indication of overall receiver operation. Cleaning If the unit requires an external cleaning use mild soap and a damp cloth. Avoid abrasive cleaners or chemicals which may damage the plastic or rubber surfaces on the unit. LBI-38378D DISASSEMBLY / REASSEMBLY TABLE 3 - TORQUE SPECIFICATIONS In the event internal service is required, disassemble the radio in accordance with the following outlined steps. See Figures 6 - 10. Reassemble the unit by following the steps in reverse order. Observe screw lengths and do not over tighten the screws when reassembling the unit. Torque specifications are listed in Table 3. CAUTION ALWAYS remove the battery pack before disassembling the unit to avoid blowing the fuse or causing other component damage. This radio contains CMOS ICs that can be damaged by static electricity. Observe static handling precau- LOCATION LB-IN.
