operating and maintenance
(servicing) instructions in the

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.
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

service or repair work is needed.
Accessories include answering machines, alerts, modems,
and fax machines. To connect an accessory, you must first
have a

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

module cover of your telephone may expose you to
dangerous voltages.

Your Display Telephone
The three MLX display phones that can be used with the
communications system are shown on the following pages.
Your Display Telephone 1-1
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.
