v SAFETY AND GENERAL INFORMATION Read this information before using your radio. IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION The information provided in this document supersedes the general safety information contained in user guides published prior to July 2000. For information regarding radio use in a hazardous atmosphere please refer to the Factory Mutual (FM) Approval Manual Supplement or Instruction Card, which is included with radio models that offer this capability. RF Operational Characteristics Your radio/radio product contains a transmitter and a receiver. When it is ON, it receives and transmits radio frequency(RF) energy. Exposure To Radio Frequency Energy Your Motorola radio/radio product is designed to comply with the following national and international standards and guidelines regarding exposure of human beings to radio frequency electromagnetic energy: lUnited States Federal Communications Commission, Code of Federal Regulations; 47 CFR part 2 sub-part J lAmerican National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992 lInstitute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition lNational Council on Radiation Protection and Measurements (NCRP) of the United States, Report 86, 1986 lInternational Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998 lNational Radiological Protection Board of the United Kingdom 1995 lMinistry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radiofrequency Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999 lAustralian Communications Authority Radiocommunications (Electromagnetic Radiation - Human Exposure) Standard 1999 (applicable to wireless phones only) To assure optimal radio/radio product performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth in the above standards, always adhere to the following procedures: ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY Facilities To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio product 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. Medical Devices Pacemakers The Health Industry Manufacturers Association recommends that a minimum separation of 15 cms be maintained between a handheld wireless radio product and a pacemaker.These recommendations are consistent with the independent research by, and recommendations of, Wireless Technology Research. Persons with pacemakers should: lALWAYS keep the radio product more than 15 cms from their pacemaker when the radio product is turned ON. lnot carry the radio product in the breast pocket. luse the ear opposite the pacemaker to minimize the potential for interference. lturn the radio product OFF immediately if you have any reason to suspect that interference is taking place. Hearing Aids Some digital wireless radio products may interfere with some hearing aids. In the event of such interference, you may want to consult your hearing aid manufacturer to discuss alternatives. NOTE Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or alternately configured for electromagnetic compatibility.
viSAFETY AND GENERAL INFORMATION Other Medical Devices If you use any other personal medical device, consult the manufacturer of your device to determine if it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this information. Safety and General Use While Driving Check the laws and regulations on the use of radio products in the area where you drive. Always obey them. When using your radio product while driving, please: lGive full attention to driving and to the road. lUse hands-free operation, if available. lPull off the road and park before making or answering a call if driving conditions so require. OPERATIONAL WARNINGS Vehicles with an air bag Potentially explosive atmospheres Blasting caps and areas WARNING: Do not place a radio product in the area over an air bag or in the air bag deployment area. Air bags inflate with great force. If a radio product is placed in the air bag deployment area and the air bag inflates, the radio product may be propelled with great force and cause serious injury to occupants of vehicle. WARNING: Turn off your radio product prior to entering any area with a potentially explosive atmosphere, unless it is a radio product type especially qualified for use in such areas as Intrinsically Safe (for example, Factory Mutual, CSA, or UL Approved). Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even death. WARNING: To avoid possible interference with blasting operations, turn off your radio when you are near electrical blasting caps, in a “ blasting area” or in areas posted “ turn off two-way radio”. Obey all signs and instructions. NOTEThe areas with potentially explosive atmospheres referred to above include fueling areas such as below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles, such as grain, dust or metal powders, and any other area where you would normally be advised to turn off your vehicle engine. Areas with poten- tially explosive atmospheres are often but not always posted. ! ! !
SAFETY AND GENERAL INFORMATIONvii MOBILE RADIO OPERATION AND EME EXPOSURE To assure optimal radio performance and that human exposure to radio frequency electromagnetic energy is within the guidelines referenced earlier in this document, transmit only when people outside the vehicle are at least the minimum distance away from a properly installed, externally-mounted antenna. Table 1 lists the minimum distance for several different ranges of rated radio power. ANTENNA INSTALLATION Mobile Antennas Recommended mobile antenna installations are limited to metal body vehicles at the center of the roof and center of the trunk deck locations. The antenna installation must additionally be in accordance with: 1.The requirements of the antenna manufacturer/supplier. 2.Instructions in the Radio Installation Manual. Fixed Site Antennas Mobile radio equipment is sometimes installed at a fixed location and operated as a control station or as a fixed unit. In such cases the antenna installation must comply with the following requirements in order to assure optimal performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth in the above standards: lThe antenna must be mounted outside the building lMount the antenna on a tower if at all possible lIf the antenna is to be mounted on a building then it must be mounted on the roof. As with all fixed site antenna installations, it is the responsibility of the licensee to manage the site in accordance with applicable regulatory requirements and may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order to insure that exposure limits are not exceeded. Table 1 Rated Power and Distance Radiated Power of Vehicle-installed Mobile Two-way RadioMinimum Distance From Transmitting Antenna 7 to 15 Watts 30.5 cm (1 Ft) 16 to 50 Watts 61 cm (2 Ft) More than 50 Watts 91.5 cm (3 Ft)
