Maintenance
Your equipment controller and MLS- and MLC-model phones are designed to
provide trouble-free performance without any special maintenance procedures.
To reduce the risk of accidental damage:
Keep the equipment modules in an area free of dust, smoke, and
moisture, and do not block the air vents by placing objects on top of the
controller.
Do not place telephones near a heating duct, radiator, or other heat
source, and do not drop or expose them to excessive shock or vibration.
Unplug the telephone if its cord is damaged, if liquid is spilled into it, or if
its housing becomes cracked or otherwise damaged.
To clean your telephone, wipe the outside housing with a soft, dust-free
cloth. If absolutely necessary, you may use a cloth slightly dampened
with a mild soap and water solution. Dry quickly with a soft cloth.
CAUTION:
Your telephone contains sensitive electronic parts. Never submerge it in
any kind of liquid, and never use detergents, alcohols, solvents, abrasive
cleaners, or an excessive amount of water when cleaning the housing
and faceplate. To do so could result in irreparable damage.
