Cleaning the BLIS camera lenses
In order to function optimally, the BLIS camera lenses must be kept clean. They can be wiped clean with a soft cloth
or wet sponge.
CAUTION
Clean the lenses carefully to avoid scratching.
The lenses are electrically heated to help melt ice or snow. If necessary, gently brush away snow from the lenses.
