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 in until it has dried 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.

■

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.

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

have a

Multi-Function Module (MFM).

WARNING:

■ For your personal safety DO NOT install an MFM

yourself.

■ ONLY an authorized AT&T technician or dealer rep-

resentative shall install, set options, or repair an MFM.

■ To eliminate the risk of personal injury due to electric

shock, DO NOT attempt to install or remove an MFM from your MLX telephone. Opening or removing the module cover of your telephone may expose you to

dangerous voltages.

Line Buttons

There are ten line buttons—two columns of five each—in the center of the phone. Use these buttons to make and receive inside calls (calls to and from other extensions) and outside calls.

Two or more line buttons are labeled either ICOM (Intercom) or SA (System Access). You have either ICOM or SA buttons,

but never both.

If you have ICOM buttons, use them for inside calls only. Use buttons labeled with phone numbers for outside calls.

If you have SA buttons, use them for both inside and outside calls. You must enter a dial-out code (usually a 9) to make an outside call on an SA button.

You can program a feature onto any unlabeled line button. See Chapter 3 for more on programming unlabeled line

buttons.

Depending on your company, you may or may not have all the

buttons described next. If your phone has SA buttons, turn to

page 1-7. If your phone has ICOM buttons, turn to page 1-9.
