Abstract

Il procedimento della presente invenzione conserva energia della batteria per un telefono senza filo, comprendente una unità di base ed una unità remota. L'unità remota presenta un ricevitore, una tastiera ed un interruttore economizzatore di batteria per permettere il funzionamento in un modo di conservazione di energia oppure in un modo normale. Il procedimento consiste nel determinare prima quale modo venga abilitato dal commutatore economizzatore di batteria. Se viene abilitato il modo di funzionamento normale, l'energia viene periodicamente applicata al ricevitore e la tastiera viene esplorata nella ricerca di un tasto azionato. Se viene abilitato il modo di preservazione di energia, la tastiera viene esplorata periodicamente nella ricerca di un tasto azionato, mentre il ricevitore rimane in uno stato privo di alimentazione di energia.The method of the present invention conserves battery power for a cordless telephone, comprising a base unit and a remote unit. The remote unit has a receiver, a keyboard and a battery saving switch to allow operation in an energy conservation mode or in a normal mode. The procedure consists in determining first which mode is enabled by the battery saving switch. If normal operating mode is enabled, energy is periodically applied to the receiver and the keyboard is explored in search of a key operated. If the power conservation mode is enabled, the keyboard is periodically scanned for a key operated, while the receiver remains in a state without power supply.
