<Cleaning procedure>
\u2022 Clear away a dirt or a foreign object on the sensor with a cotton swab.
\u2022 When a dirt is left even if you cleaned the sensor by above procedure, clear away a dirt or a foreign object on the sensor using a cotton swab dampened with the alcohol.
And, wipe off the sensor with a dry cotton swab afterwards. <\/td>		–<\/td>–<\/td><\/tr>
