Troubleshooting
5.1. During operation, the light should be aimed straightly on the resin to ensure
solidification effectively.
5.2. Never aim the light directly at unprotected soft tissues because it may lead to
injury or irritation. Do not aim the light at eyes. Light reflected from the tooth surface
may also injure eyes. Use the protective shield supplied with the unit or suitable
light filtering safety glasses.
