    SAFETY AND GENERAL INFORMATION 
    IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION
    READ THIS INFORMATION BEFORE USING YOUR MOTOROLA TWO-WAY RADIO  
    The information provided in this document supersedes the general safety information contained in user guides 
    published prior to October 2000. For information regarding radio use in a hazardous atmosphere refer to the 
    Factory Mutual (FM) manual supplement included with radio models that offer this capability and/or the 
    intrinsic safety radio information section of this user manual. 
    RADIO FREQUENCY (RF) OPERATIONAL CHARACTERISTICS 
    To transmit (talk) you must push the Push-To-Talk button; to receive (listen) you must release the 
    Push-To-Talk button.  
     When the radio is transmitting, it generates radio frequency (RF) energy; when it is 
    receiving, or when it is off, it does not generate RF energy. 
    PORTABLE RADIO OPERATION AND EME EXPOSURE 
    Your Motorola radio is designed to comply with the following national and international standards and 
    guidelines regarding exposure of human beings to radio frequency electromagnetic energy (EME):
    ¥ United States Federal Communications Commission, Code of Federal 
    Regulations; 47 CFR part 2 sub-part J
    ¥ American National Standards Institute (ANSI) / Institute of Electrical and 
    Electronic Engineers (IEEE) C95. 1-1992
    ¥ Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition
    ¥ National Council on Radiation 
    Protection and Measurements (NCRP) of the United States, Report 86, 1986
    ¥ International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
    ¥ Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radio Frequency Electromag-
    netic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999
    ¥ Australian Communications Authority Radiocommunications (Electromagnetic Radiation - Human Expo-
    sure) Standard 1999 (applicable to wireless phones only)  
    To assure optimal radio 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:
    Two-way Radio Operation  
    When using your radio,   
    hold the radio in a vertical position with the microphone one to 
    two inches (2.5 to 5 centimeters) away from the lips.
    Body-worn Operation  
    To maintain compliance with FCC RF exposure guidelines, if you wear a radio on your body 
    when transmitting, always place the radio in   
    a Motorola approved clip, holder, holster, 
    case, or body harness for this product  
    . Use of non-Motorola-approved accessories may exceed FCC RF 
    exposure guidelines.   
    If you do not use a Motorola approved body-worn accessory and are not using the 
    radio in the intended use positions along side of the head in the phone mode or in front of the face in 
    the two-way radio mode, then ensure the antenna and radio is kept the following minimum distances 
    from the body when transmitting:  
    ¥ Phone or Two-way radio mode: one inch (2.5 centimeters)
    ¥ Data operation using any data feature with or without an accessory cable: one inch (2.5 centimeters) 
    MAN WITH RADIO 
    						
    							 
    iiSafety and General Information 
    Antenna Care
    Use only the supplied or an approved replacement antenna. 
     Unauthorized  antennas, modiÞcations, or 
    attachments could damage the radio and may violate FCC regulations. 
    DO NOT hold the antenna when the radio is ÒIN USEÓ.  
    Holding the antenna affects call quality and may 
    cause the radio to operate at a higher power level than needed. 
    Approved Accessories 
    For a list of approved Motorola accessories look in the appendix or accessory section of your radioÕs User 
    Guide. 
    ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY 
    Note: 
    Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately 
    shielded, designed or otherwise conÞgured for electromagnetic compatibility.  
    Facilities 
    To avoid electromagnetic interference and/or compatibility conßicts, 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. 
    Aircraft 
    When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in 
    accordance with applicable regulations per airline crew instructions. 
    Medical Devices
    ¥ Pacemakers 
    The Health Industry Manufacturers Association recommends that a minimum separation of 6 inches (15 
    centimeters) be maintained between a handheld wireless radio and a pacemaker.These recommenda-
    tions are consistent with those of the U.S. Food and Drug Administration.
    Persons with pacemakers should:
    ¥ ALWAYS keep the radio more than 6 inches (15 centimeters) from their pacemaker when the radio is 
    turned ON.
    ¥ Not carry the radio in the breast pocket.
    ¥ Use the ear opposite the pacemaker to minimize the potential for interference.
    ¥ Turn the radio OFF immediately if you have any reason to suspect that interference is taking place. 
    ¥ Hearing Aids 
    Some digital wireless radios may interfere with some hearing aids. In the event of such interference, you 
    may want to consult your hearing aid manufacturer to discuss alternatives. 
    ¥ 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 Informationiii 
    SAFETY AND GENERAL 
    Use While  Driving 
    Check the laws and regulations on the use of radios in the area where you drive. Always obey them.
    When using your radio while driving, please:
    ¥ Give full attention to driving and to the road.
    ¥ Use hands-free operation, if available.
    ¥ Pull off the road and park before making or answering a call if driving conditions so require. 
    OPERATIONAL WARNINGS 
    FOR VEHICLES WITH AN AIR BAG 
    Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air 
    bags inßate with great force. If a portable radio is placed in the air bag deployment area and the 
    air bag inßates, the radio may be propelled with great force and cause serious injury to 
    occupants of the vehicle. 
    POTENTIALLY EXPLOSIVE ATMOSPHERES 
    Turn off your radio prior to entering any area with a potentially explosive atmosphere, unless it is a radio type 
    especially qualiÞed for use in such areas as Intrinsically Safe (for example, Factory Mutual, CSA, UL, or 
    CENELEC). Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive 
    atmosphere can cause an explosion or Þre resulting in bodily injury or even death. 
    Note: 
    The 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 potentially explosive atmospheres are 
    often but not always posted. 
    BLASTING CAPS AND AREAS 
    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.Ó Obey all signs and instructions. 
    OPERATIONAL CAUTIONS 
    ANTENNAS
    Do not use any portable radio that has a damaged antenna. 
     If a damaged antenna comes 
    into contact with your skin, a minor burn can result. 
    BATTERIES 
    All batteries can cause property damage and/or bodily injury such as burns if a conductive material such as 
    jewelry, keys, or beaded chains touch exposed terminals. The conductive material may complete an electrical 
    circuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when 
    placing it inside a pocket, purse, or other container with metal objects.
