Abstract

A portable radio communication apparatus includes a timer for counting a preselected period of time since the turn-on of a power switch. On the elapse of the preselected period of time, the apparatus automatically sets up a power saving mode in which the apparatus repeatedly turns on and turns off its display at preselected intervals. In this configuration, the display is automatically turned on and turned off while the apparatus is in its waiting state, thereby saving power while displaying necessary information for the user of the apparatus intermittently.
