ABSTRACT:
A cellular phone both annunciates and retrieves stored mail messages using a single keypad button. A cellular basestation transmits voice mail messages to the cellular phone indicating that voice mail is ready for retrieval. A light emitting diode (LED) is located underneath a translucent button on the phone keypad and is activated when the voice mail message is received by the cellular phone. The illuminated button is then activated initiating a dialing operation that retrieves the voice mail. Battery charge is measured in a dual mode analog and digital cellular phone according to the various digital and analog modes presently performed. The different measurement values are averaged to provide a more accurate calculation of the amount of charge remaining in the battery supply.
