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.
