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 flowchart 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

wavelength band. Since direct or diffuse laser radia-

tion can inflict 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.
