Lens Cleaning
Delicate Lenses: Please follow these instructions carefully to avoid lens damage.
Precautions
To protect the lens from damage, follow these guidelines.
- Never touch the lens with hard or abrasive objects.
- Do not use solvents to clean the lens. Solvents may remove the lens coating.
- Do not use lens cleaning papers or tissues to wipe the lens. These products are abrasive and will scratch the lens.
Lens Cleaning Kit
This is provided with your camera and includes the following components.
- Air bulb blower
- Lens cleaning solution
- Wiping cloth
- Cotton swabs
Lens cleaning Procedure
Excessive dust or debris on the camera lens can reduce measurement accuracy. To clean the lens, follow this procedure.
- Use the air bulb blower and brush to remove any dust or loose grit from the lens.
- Put a few drops of the cleaning solution on the cloth and gently wipe across the lens (not round and round). Use only enough pressure to remove the smudges (do not rub hard).
- Use the cotton swabs for tougher lens grime but avoid rubbing the same spot over and over.
