The exclamation point in an
equilateral triangle is intended to
alert the user to-the presence of
important operating and
maintenance (servicing)
instructions in the literature
accompanying the product.
IMPORTANT SAFETY INSTRUCTIONS
Always follow these basic safety precautions when using your
telephone equipment. These precautions reduce the risk of
fire, electrical shock, and injury to you and damage to the
equipment.
■ Read and understand all instructions.
■ Follow all warnings and instructions marked on or
packed with the telephone.
■ Do not use the telephone near water, as in a wet
basement. The telephone can be hazardous if
immersed in water. To avoid the possibility of
electrical shock, do not use it when you are wet. If you
accidentally drop it into water, do not retrieve it until
you have first unplugged the line cord from the
modular wall jack. Do not plug the telephone back in
until it has dried thoroughly.
vii
Do not use the telephone during electrical storms in
your immediate area. There is a remote risk of
electrical shock from lightning.
Unplug the telephone from the wall outlet before
cleaning. Use a damp cloth for cleaning. Do not use
liquid or aerosol cleaners on the telephone.
Never push objects of any kind into the telephone
through openings or slots. Never spill liquid of any
kind on the telephone.
Do not use the telephone near a gas leak. If you
suspect a gas leak, report it immediately, but use a
telephone away from the area in question. The
telephone’s electrical contacts could generate a tiny
spark. While unlikely, it is possible that the spark could
ignite heavy concentrations of gas.
viii
To reduce the risk of electrical shock, do not
disassemble the telephone. There are no userserviceable parts inside. Opening or removing covers
may expose you to hazardous voltages, and incorrect
reassembly can cause electrical shock when the
telephone is used.
Call your sales representative or authorized dealer
when service or repair work is needed.
