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
serious
personal
injury
This product emits
invisible
infrared laser radiation in the 9.3–10.6 µm CO
2
wave-
length band. Direct or diffuse laser radiation can inflict severe corneal injuries and can
seriously burn human or animal tissue. Service personnel troubleshooting Firestar lasers
should be thoroughly trained in laser safety practices and electronic service techniques
before attempting repairs.
Caution
possible
equipment
damage
Attempting repair of a SYNRAD Firestar laser without the express authorization
of SYNRAD, Inc. will void the product warranty. If troubleshooting or service as-
sistance is required, please contact the SYNRAD Service Department.
