General product care

To keep your telephone working well and looking good, follow these guidelines:

Avoid putting it near heating appliances and devices that generate electrical noise (for example, motors or fluorescent lamps).

DO NOT expose it to direct sunlight or moisture.

Avoid dropping the telephone or treating it roughly.

Clean with a soft cloth.

Never use a strong cleaning agent or abrasive powder because this can damage the finish.

Retain the original packaging in case you need to ship it at a later date.
