Care and maintenance
Your AT&T telephone contains sophisticated electronic parts, so it must be
treated with care. To keep your telephone working properly and looking good,
follow these guidelines:
Location
Avoid putting the telephone near appliances and devices which generate
electrical noise (e.g. motors or fluorescent lamps).
Do not expose to direct sunlight or moisture.
Avoid rough treatment
Place the handset down gently.
Avoid dropping the handset and the telephone base.
Retain the original packaging and receipt in case you need to return the
telephone later.
