To keep your telephone 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.
