ABSTRACT:
An electronic clock radio using a clock integrated circuit and a radio integrated circuit. A first energizing potential when applied to the NAP/SLEEP input connection of the clock circuit, causes the clock circuit to switch from a first electric state to a second electric state. After a selected interval of time, not greater than 60 minutes, the clock circuit switches from the second electric state to the first electric state. The radio, normally in an OFF state is placed in an ON state only upon receiving a second energizing potential applied to its input connection. A control circuit, having a manually operable switch with NAP and SLEEP positions and being responsive to the electric states of the clock circuit, connects this second energizing potential to the radio input only when:
(i) the manually operable switch is in the NAP position and the clock circuit is the first electric state, or
(ii) the manually operable switch is in the SLEEP position and the clock circuit is in the second electric state.
