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. These suggestions will enable you to take full advantage of your new voice terminal. Then, retain these tips for later use.


All powering over telecommunication wiring must be via UL listed power supplies with outputs of 42-56Volts DC,1.3 Amps DC.

This telephone is NOT for residential use. It is for business systems applications ONLY. It will NOT operate on public networks. 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 optional AC power used in these applications may create a safety hazard by placing a direct short circuit across the telephone wiring.


When using your telephone equipment, the following safety precautions should always be followed to reduce the risk of fire, electric shock, 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. Do not use this product near water, for example, near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement or near a swimming pool. 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 wall jack. Then, call service personnel to ask about a replacement.

Avoid using the telephone during 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.
