General cleaning information: The laser shield and camera lenses must be kept clean. The instructions must be followed as described in this chapter to clean these surfaces.
Dust and debris on optical surfaces: Use the BLK cleaning cloth to remove dust and debris from these surfaces.
☞ The BLK cleaning cloth must be clean and free from dirt, dust or particles.
☞ Never rub off dust or debris as this will scratch the surface and possibly causing permanent damage to the special optical coatings.
Cleaning of optical surfaces: Soiling of the laser shield can cause extreme measurement errors and therefore useless data.
☞ All soiling that is visible on the laser shield must be removed, except
for single small dust particles that adhere inevitably.
For the cleaning procedure, the BLK cleaning cloth is recommended.
Clean the laser shield and camera lenses regularly with the BLK cleaning
cloth:
- Switch off the BLK360 and remove the battery.
- Use the BLK cleaning cloth and gently clean the laser shield.
- If any smears from cleaning are visible against back light, repeat the
procedure.
