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.
