发明名称 CORDLESS TELEPHONE
摘要 <p>A cordless telephone has a transfer capability by which an incoming telephone call may be transferred from the base unit to the handset unit or from the handset unit to the base unit. Each unit includes an intercom key which may be actuated to place the telephone in an intercom mode wherein the base unit and the handset unit are in communication with each other while the incoming call is on hold. Deactuation of one unit in the intercom mode results in the other unit being automatically adapted to receive the incoming call. Alternatively, actuation of either intercom during the intercom mode results in both units being automatically adapted to receive the incoming call and placed in communication with each other.</p>
