Introduction
This section is designed to help isolate problems to the module level only. Problems on circuit boards or
the laser tube are outside 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/replacement
information. To troubleshoot the Firestar v40 laser, it is necessary to understand the sequence of events
that must happen before the laser can turn on and operate. Before you attempt to perform any service,
we advise you to read the entire troubleshooting guide and review both the operational owchart and the
functional block diagram. Symptoms and possible causes are highlighted by dark print and bullet points
throughout this section. Information about each symptom and cause can be found in the paragraphs fol-
lowing each heading.
Caution
possible
equipment
damage
Attempting repair of a SYNRAD Firestar laser without the express
authorization of SYNRAD will void the product warranty. If trou-
bleshooting or service assistance is required, please contact the
SYNRAD Service Department.
Danger
serious
personal
injury
This Class IV laser product emits invisible infrared laser radiation in
the 10.6 µm CO
2
wavelength band. Since direct or diuse laser radia-
tion can inict severe corneal injuries, always wear eye protection
when in the same area as an exposed laser beam. Do not allow the
laser beam to contact a person. This product emits an invisible laser
beam that is capable of seriously burning human tissue.
Always be aware of the beam’s path and always use a beam block
while testing.
