10.5 Daily Maintenance

Please clean dome cover regularly to continue receiving clear imagery. Handle the cover with care. Use water to
wash. Don't use a cloth to clean. Use mild detergent to clean the cover if there is too much dust to just.
Note:
Please take care not to touch plating surface with bare hands or skin, as this might transfer bodily perspiration
upon it and the acidity of the perspiration may erode it. Uncovered hands may also cause nail scratches to the
dome cover when handling. This will result in blurred images and impaired visual monitoring when using the
device.
