Synrad Firestar OEM v30 reference guide
Troubleshooting
This section is designed to help isolate Firestar OEM v30 lasers problems to the board level only. Problems on circuit boards
or the laser tube are not within the scope of this guide because they are not user-serviceable assemblies; do not attempt to
repair them. Contact SYNRAD or a SYNRAD Authorized Distributor for repair or replacement information.
Danger

personal
injury
This product emits invisible infrared laser radiation in the 9.3–10.6 µm CO

should be thoroughly trained in laser safety practices and electronic service techniques
before attempting repairs.
