Motorola MA550 Series Start Here Manual page 13

Because cordless phones operate on electricity, you
should have at least one phone in your home that isn't
cordless, in case the power in your home goes out.
To avoid interference to nearby appliances, do not place
the base of the cordless phone on or near a TV,
microwave oven, or VCR.
Caution! To maintain compliance with the FCC's RF exposure
guidelines, place the base unit at least 20 cm from
nearby persons.
