ABSTRACT:
A radio apparatus having a battery saving function comprising an indicator for indicating that power is being supplied. An indicator is actuated in synchronization with the battery saving operation. In particular, a receiving circuit is intermittently triggered by the power supply and the indicator is intermittently triggered in synchronization with at least some of the power supply signals that trigger the receiving circuit. The period of actuation for the indicator may be less than the receiving circuit, which is intermittently actuated in accordance with a battery saving operation. Also, the indicator means may be actuated once for each n times that the receiving means is actuated.
