IMPORTANT SAFETY INSTRUCTIONS

Always follow these basic safety precautions when using your telephone equipment. These precautions reduce the risk of fire, electric 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 thoroughly.

Do not use the telephone (other than a cordless-type telephone) during electrical storms in your immediate area. There is a remote risk of electric 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 phone.

until it has dried

vii

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 spark could ignite heavy concentrations of gas.

Never push objects of any kind into the telephone openings or slots. Never spill liquid of any kind on telephone.

To reduce the risk of electric shock, do not disassemble the telephone. There are no user-serviceable parts inside.

Opening or removing covers may expose you to hazardous

voltages, and incorrect reassembly can cause electric shock when the telephone is used.

Call your AT&T representative or authorized dealer when service or repair work is needed.

Accessories include answering machines, alerts, modems, and fax machines. To connect an accessory, you must first

How to Comment

Your Display Telephone

The MLX-10D,™ the MLX-20L,™ and the MLX-28D™ phones are all digital/lSDN display phones. The differences are the

number of buttons available (10, 20, or 28) to make and

receive calls, and the size of the display.

Your display phone is part phone, part intercom, and part

computer. It has touch-tone dialing, a speakerphone, and programming capabilities.

The display shows you the number you are calling, gives you information about incoming calls, lists features for using the phone, and gives you programming instructions.

The three MLX display phones that can be used with the communications system are shown on the following pages.

The Display Area

The display on your phone makes it easy to handle calls and

use your system’s many features. It acts as an alarm clock, timer, phone book, message center, and helps you locate features you want to use or program. The more you use it, the more uses you will find for it.

If you have an MLX-20L phone, you have the large (7-line by 24-character) display. If you have an MLX-10D or MLX-28D phone, you have the small (2-line by 24-character) display.
