Introduction
This section is designed to help isolate problems to the module 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.
To quickly troubleshoot the Series 48 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 the relevant schematic diagrams.
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 following each heading.
