Banner WORLD-BEAM QS18 Laser Series - Manual (Page 2)

Description of Laser Classes
Class 1 Lasers
Class 1 lasers are lasers that are safe under reasonably foreseeable conditions of operation, including the use of optical
instruments for intrabeam viewing.
Reference IEC 60825-1:2001, Section 8.2.
Class 1 Laser Characteristics: See Specifications.
CAUTION: Do Not Disassemble for Repair
This device contains no user-serviceable components. Do not
attempt to disassemble for repair. Use of controls or
adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure. A
defective unit must be returned to the manufacturer.
For Safe Laser Use (Class 1 or Class 2):
• Do not stare at the laser.
• Do not point the laser at a person’s eye.
• Mount open laser beam paths either above or below eye level, where practical.
• Terminate the beam emitted by the laser product at the end of its useful path.
