  • Page 3: Safety Information

    Read this information before using the radio. PRODUCT SAFETY AND RF EXPOSURE FOR PORTABLE TWO-WAY RADIOS. This document provides information and instructions for the safe and efficient operation of Motorola Portable Two-Way Radios. The information provided in this document supersedes information contained in user guides published prior to February 2002.
  • Page 4 Compliance with RF Exposure Standards Your Motorola two-way radio is designed and tested to comply with a number of national and International standards and guidelines (listed below) for human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits for occupational/controlled RF exposure environments at operating duty factors of up to 50% talk- 50% listen and is authorized by the IEEE/ICNIRP for occupational use only.
  • Page 5 Motorola - approved antennas, batteries and accessories may exceed IEEE/ICNIRP RF exposure guidelines. For a list of Motorola-approved antennas, batteries, and other accessories please see your dealer or local Motorola contact. Your nearest dealer can be found at the following web site: http://www.motorola.com/cgiss/emea/dealerlocator.html Additional Information For additional information on exposure requirements or other training information, visit http://www.motorola.com/rfhealth.
  • Page 6 ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY NOTE: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed or otherwise configured for electromagnetic compatibility. Facilities To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.

  • Page 7: Operational Warnings

    OPERATIONAL WARNINGS Vehicles with an air bag Refer to vehicle manufacturer's manual prior to installation of electronic equipment to avoid interference with air bag wiring. WARNING: Do not place a portable radio in the area over an air bag or in the air bag deployment area.

  • Page 8: Intrinsically Safe Radio Information

    Warnings for Radios Approved as Intrinsically Safe Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability and the intrinsic safety approval labelling (FM, UL, CSA, CENELEC or ATEX). Radios will not be upgraded to this capability and labeled once they have been shipped to the field.
  • Page 9 The manual PN referenced on the Intrinsically Safe Approval Label identifies the approved Accessories and or options that can be used with that portable radio unit. Using a non Motorola intrinsically safe battery and or accessory with the Motorola approved radio unit will void the intrinsically safe approval of that radio unit.
