First introduced in 1984, the handheld portable cellular telephone is one of the most exciting and innovative electronic products ever developed. With it you can stay in contact with your office, home, emergency services, and others.

For the safe and efficient operation of your phone, observe the following guidelines:

Your cellular telephone is a radio transmitter and receiver that receives and sends radio frequency (RF) energy. The phone operates on a frequency range of 824 MHz to 894 MHz using commonly employed frequency modulation (FM) techniques. The power level can range from 0.006 watts to 0.6 watts.

In 1991 the Institute of Electrical and Electronics Engineers (IEEE) and in 1992 the American National Standards Institute (ANSI) updated the 1982 ANSI Standard for safety levels with respect to human exposure to RF energy. In March 1993, the US Federal Communications Commission (FCC) proposed adoption of the updated ANSI Standard. The design of your phone complies with this Standard. If you want to limit RF exposure even further, you may choose to limit the duration of calls and operate the phone in the most power efficient manner.

For your phone to operate at the lowest power level, consistent with good call quality, please observe the following guidelines:

DO NOT use your phone with a damaged antenna. Use manufacturer-approved antennas, and have authorized service centers do the work. Non-manufacturer-approved antennas, modifications, or attachments could impair call quality, damage the phone, void your warranty, and violate FCC regulations.

Check the laws and regulations on the use of cellular telephones in the areas in which you drive. Always obey them. While driving, follow these guidelines:

Most modern electronic equipment is shielded from RF energy; however, RF energy from cellular telephones may affect inadequately shielded equipment. Check with the manufacturer to determine if equipment is adequately shielded from external RF energy. You should also check with the manufacturer of any equipment that has been added to a vehicle.

Consult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc.) to determine if they are adequately shielded from RF energy.

Turn your phone OFF in health care facilities.

To prevent interference with aircraft navigation and communications systems, US Federal Aviation Administrations (FAA) regulations require you to have permission from a crew member to use your cellular phone while an aircraft is on the ground. FCC regulations prohibit the operation of cellular phones in flying aircraft.

Do not allow children to play with your phone. It is not a toy. Children could hurt themselves or others, damage the phone, or place expensive accidental calls.

Turn your phone OFF whenever you are near a blasting area, or whenever you see the sign, Turn off two-way radio. Construction crews use remote control RF devices to set off explosives.

Turn your phone OFF when in any area with a potentially explosive atmosphere. It is rare, but your phone or its accessories could generate sparks, which could cause an explosion or fire.

Areas with potentially explosive atmospheres are often, but not always, clearly marked. They include fueling areas such as gas stations; below deck on boats; fuel or chemical transfer and storage facilities; areas where the air contains chemicals or particles, such as grain, dust, or metal powders; and any areas where you are advised to turn off your vehicle’s engine.

Do not transport or store flammable gas in the compartment of your vehicle which contains your phone or its accessories.

Vehicles running on liquefied petroleum gas (propane or butane) must comply with the National Fire Protection Standard (NFPA-58). For a copy of this Standard contact the National Fire Protection Association, One Batterymarch Park, Quincy, MA 00269, ATTN.: Public Sales Division.
