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 careful ly the he lpful tip s liste d 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. It will NOT operate on public networks. It MUST
BE connected to a DEFINITY Enterprise Communications Server.
Use in a residential environm ent could resul t in an electrical short
circuit when the telephone wiring is set up to provide other
applications, for example, for appliance control or power
transformers. T he AC pow e r u sed i n the se a ppl ic atio ns m ay c rea te a
safety hazard by placing a direct short circuit across the telephone
wiring.

Use

When using your telephone equipment, the following safety precautions
should alway s be fol lowed to re duce the risk o f fire, ele ctric s hock, an d 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 te lepho ne into wate r, do not retrieve it until you hav e
first unplu gge d the li ne co rd from the modular wall jack. The n, call service
personnel to ask about a replacement.

• Avoid using the telephone during electrical storm s 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.
