Zusammenfassung:A mobile telephone is arranged to detect when its battery voltage has fallen such that only the lowest segment of the four segment battery charge level bar of its LCD display is showing, and, in response, to transmit a "Pager Mode" message to a predetermined network destination number, and then to disable its transmit function. An audio signal is generated to alert the user, and a warning message is displayed, e.g. Battery Low, Pager Mode. Pager Mode is a selectable option via the telephone's menu. The mobile network, upon receipt of such a "Pager Mode" message, sets a "Pager Mode" flag in the user's profile. For an originating call the profile is accessed in the normal manner, and, if that flag is set, the network sends a "Receive Only - Leave Message" announcement to the caller.
