Calls cannot be made from the handset if the telephone base is unplugged
or switched off, or if the electrical power is interrupted.
Power adapter: The power adapter is intended to be correctly oriented in a
vertical or floor mount position. The prongs are not designed to hold the plug in
place if it is plugged into a ceiling or under-the-table/cabinet outlet.
