Maintenance
Regular maintenance ensures the longevity and optimal performance of your laser light.
- Cleaning: Use a soft, dry cloth to clean the exterior of the unit. For optical components, use a lens cleaning solution and a microfiber cloth. Do not use abrasive cleaners.
- Storage: Store the unit in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Smoke Machine Usage: As noted in the features, using a smoke machine significantly enhances the visual effects of the laser beams. Without smoke, you will primarily see patterns and animated graphics rather than dynamic beams.
Troubleshooting
| Problem | Possible Cause | Solution |
