IMPORTANT USER SAFETY
INSTRUCTIONS
The most careful attention has been devoted to quality standards in the
manufacture of your new telephone. Safety is a major factor in the design of
every set. But, safety is YOUR responsibility too.
Please read carefully the helpful tips listed below and on the next page. These
suggestions will enable you to take full advantage of your new voice terminal.
Then, retain these tips for later use.
!CAUTION:
This telephone is NOT for residential use. It is for business systems
applications ONLY. Use in a residential environment could result in
an electrical short circuit when the telephone wiring is set up to
provide other applications, for example, for appliance control or
power transformers. The AC power used in these applications may
create a safety hazard by placing a direct short circuit across the
telephone wiring.
Use
When using your telephone equipment, the following safety precautions
should always be followed to reduce the risk of fire, electricshock, and injury to
persons.
•Read and understand all instructions.
•Follow all warnings and instructions marked on the telephone.
•This telephone can be hazardous if immersed in water. To avoid the
possibility of electric shock, do not use it while you are wet. If you
accidentally drop the telephone into water, do not retrieve it until you have
first unplugged the line cord from the modular jack. Then, call service
personnel to ask about a replacement.
•Avoid using the telephoneduring electrical storms in your immediate area.
There is a risk of electric shock from lightning. Urgent calls should be
brief. Even though protective measures may have been installed to limit
electrical surges from entering your business, absolute protection from
lightning is impossible.
•If you suspect a natural 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 this
spark could ignite heavy concentrations of gas.

•Never push objects of any kind into the equipment through housing slots
since they may touch hazardous voltage points or short out parts that
could result in a risk of electric shock. Never spill liquid of any kind on the
telephone. If liquid is spilled, however, refer servicing to proper service
personnel.
•To reduce the risk of electric shock, do not disassemble this telephone.
There are no user serviceable parts. Opening or removing covers may
expose you to hazardous voltages. Incorrect reassembly can cause
electric shock when the telephone is subsequently used.
Service
1. Before cleaning, unplug the telephone from the modular wall jack.
Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for
cleaning.
2. Unplug the telephone from the modular wall jack. Be sure to refer
servicing to qualified service personnel when these conditions exist:
— If liquid has been spilled into the telephone.
— If the telephone has been exposed to rain or water.
— If the telephone has been dropped or the housing has been
damaged.
— If you note a distinct change in the performance of the telephone.
