PURPOSE:To make it possible to perform actuation checking in a short time for brightness level sensing fuction by sensing the level of brightness and determining whether or not there is voice output when an actuation check key for the brightness lesensing function is operated. CONSTITUTION:When the ambient brightness is over a set level, the CPu supplies on the hour based on the signal of a light senser CdS informations of present time to a voice synthesizer VS and makes the speaker SP output it. When a check key is operated and after present time is output from the speaker SP, a melody is sounded from the speaker SP, if the ambient brightness that is sensed by the light senser Cds is over a set level. Accordingly the actuation check for brightness level sensing function can be performed by whether or not there exists a melody. |
