IMPORTANT SAFETY INSTRUCTIONS
Always follow basic safety precautions when using your telephone equipment to
reduce the risk of fire, electrical shock, and injury.
1. Read and understand all instructions in the Owner’s Instruction Manual.
2. Read all warnings and follow all instructions marked on the product.
3. Unplug this product from the wall outlet before cleaning. Use a damp
cloth for cleaning. Do not use liquid or aerosol cleaners.
4. Do not use the telephone near water. For example, do not use near a
bathtub, wash bowl, kitchen sink, laundry tub, swimming pool, or in a wet
basement.
5. Do not place this product on an unstable cart or stand. The product may
fall causing serious damage to the product.
6. Use only the type power source indicated on the label. If you are not sure
of the type power supply to your home, consult your dealer or local power
company.
7. Do not place any objects on the telephone line cord. Do not locate the
telephone where the line cord will be walked on.
8. Do not block or cover ventilation slots and openings in the bottom of the
telephone. The openings should never be blocked by placing the telephone
on a bed, sofa, rug, or other similar surfaces. The telephone should never be
placed near or over a radiator or heat register. The telephone should never
be placed in a built-in installation unless proper ventilation is provided.
9. Never spill liquid on the telephone or push objects of any kind through
ventilation slots. Liquid or objects may touch dangerous voltage points or
short out parts that could result in a risk of fire or electrical shock.
10. Do not disassemble this product. Opening or removing covers may expose
you to dangerous voltages or other risks. Incorrect reassembly can cause
electrical shock when the product is subsequently used.
11. Do not overload outlets and extension cords. Some telephones require
AC power from an outlet. Overloading the outlets can result in the risk of fire
or electric shock.
12. Avoid using a telephone during a local thunderstorm. There may be a
remote risk of electrical shock from lightning.

6
13. Do not use a telephone to report a gas leak in the vicinity of the leak.
14. Unplug the telephone from the wall outlet and refer servicing to qualified
service personnel under the following conditions:
•When the line cord is frayed or plugs damaged.
•If liquid has been spilled into the telephone.
•If the telephone has been exposed to rain or water.
•If the telephone does not operate properly by following the operating
instructions. (Adjust only those controls covered by the operating
instructions. Improper adjustment of other controls may result in
damage and will often require extensive work by a qualified
technician to restore the product to normal operation.)
•If the telephone has been dropped or the housing damaged.
•If the telephone exhibits distinct change in performance.
