Care and Maintenance
To keep your telephone set working well and looking good, follow these
few simple guidelines.
• Avoid putting the telephone near heating appliances and devices that
generate electrical noise.
• The telephone should not be exposed directly to sunlight or moisture.
• Avoid dropping the handset and other rough treatment.
• Clean the telephone using a soft cloth moistened with a mild cleaning
solution. Remove all traces of the cleaner with a damp cloth.
• Never use cleaners containing alcohol, strong cleaners that may
corrode plastic, or abrasive powders, as this may damage the finish.
