Children
Do not allow children to play with your phone. It is not a toy. Children could hurt themselves or others
(by poking themselves or others in the eye with the antenna, for example). Children also could
damage the phone, or make calls that increase your telephone bills.
▣
Blasting Areas
To avoid interfering with blasting operations, turn you unit OFF when in a “blasting area” or in areas
posted “Turn off two-way radio”. Construction crews often use remote control RF devices to set off
explosives.

Potentially Explosive Atmospheres
Turn your phone OFF when in any area with a potentially explosive atmosphere. It is rare, but your
phone or accessories could generate sparks. Sparks in such area could cause an explosion or fire
resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include
fueling areas such as gas station; below deck on boats; fuel or chemical transfer or storage facilities;
areas where the air contains chemical 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.
Do not transport or store flammable gas, liquid, or explosives in the compartment of your vehicle
which contains your phone or accessories.
Vehicles using liquefied petroleum gas (such as propane or butane) must compl7y with the National
Fire Protection Standard (NFPA-58). For a copy of this standard, contact the National Fire Protection
Association, One Battery march Park, Quincy, MA 02269, Attn: Publication Sales Division.
Rule of Thumb: Using common sense at all times when handling, installing or
using the phone. Any questions should be directed to you nearest Service
Center or authorized service technician or electrician.
