<p>PURPOSE:To automatically inform a user of the current operating mode by actuating the blinking display via oscillator which corresponds to the operating mode. CONSTITUTION:When the operating mode is switched, an output circuit 16 emits the oscillation outputs of a human sense automatic mode oscillator 7 for mode, manual On mode oscillator 9, and all-night lamp mode oscillator 11 through multiplexer 12-14 corresponding to the current mode switched. Indicator lamp is blinked with a certain constant frequency and duty cycle corresponding to the current mode, and the user is certainly informed of the current operating mode automatically.</p> |
