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.
