WARNING
Oscillator Burns Amplifier Burns
The voltage setting on the PU600C series power units at the time of installation, may NOT be exceeded
without consulting the Continuum Service office first. Exceeding the designated voltage can result in
free-running (see Section II), thermal focusing and optical damage. Failure to follow these precautions
will result in voiding the warranty (see Section VII).

Preface
This manual describes how to operate and maintain the Continuum
Precision II series Laser.
Conventions Used in this Manual
LASER RADIATION!
This symbol alerts you to laser radiation hazards during
operation or maintenance procedures.
WARNING!
This symbol warns of other possible risks not related to
laser radiation or electrical hazards.
CAUTION!
This symbol alerts you to a process or procedure that, if not
properly done or followed exactly, will damage the laser or
irrevocably change operating software.
This symbol draws your attention to important or extra infor-
mation that relates to the current subject matter.
Manual Organization
Chapter 1, Safety, provides all the appropriate safety procedures and
warning labels. These instructions must be followed to ensure safe
operation of the laser equipment.
Chapter 2 describes operating instructions for the Precision II series
lasers. A brief installation description is given at the end of the chapter.
Installation of this laser may only be performed by a Continuum cus-
tomer engineer.
Chapter 3 describes the electronic modules and how they work in detail.
These descriptions are enhanced with schematics and drawings.
Chapter 4 describes the routine maintenance procedures to keep the
equipment operating properly. Only those procedures listed may be
performed by the operator.
