Title: METHOD OF FAILURE PREVENTION FOR ELECTRONIC EQUIPMENT
Abstract:
[Problem] In a mobile telephone, to make it possible to prevent specific faults beforehand by detecting a pre-fault condition of the specified fault. [Solution] A mobile telephone is provided with: a speaker (5), a microphone (6) and a liquid crystal display panel (4), and is also provided with a plurality of known data sets respectively corresponding to a normal condition in which there is no pre-fault condition anywhere and to a plurality of assumed pre-fault conditions. First of all, the mobile telephone emits a tone of a specified frequency from the speaker (5). Next, the tone emitted from the speaker (5) is detected by the microphone (6). Next, unknown data are created corresponding to the tone detected by the microphone (6). Next, by comparing the unknown data with a plurality of sets of known data, known data are identified corresponding to the unknown data. Next, the liquid-crystal display panel (4) is used to indicate whether the mobile telephone is in a normal condition, with no pre-fault condition anywhere, or is in a pre-fault condition, corresponding to the known data that has thus been identified. As a result, it is possible to prevent specific faults before the occurrence thereof.
