2 Safety Information
Electrical Safety Information
Laser Safety Information (ELS-500 and
EOT-500 without VFL)
Your instrument is a Class 1M laser product in compliance with standards
IEC 60825-1 Amendment 2: 2001 and 21 CFR 1040.10. Invisible laser radiation may
be encountered at the output port.
The product is safe under reasonably foreseeable conditions of operation but it may
be hazardous if you use optics within a diverging or collimated beam. Do not view
directly with optical instruments.
Note: Label shown for information purposes only. It is not affixed to your
product.
Note: Units without VCSEL sources are Class 1 products.
WARNING
Use the AC adapter provided with this product
indoors only.
WARNING
Do not install or terminate fibers while a laser source is active. Never
look directly into a live fiber and ensure that your eyes are protected
at all times.
WARNING
Use of controls, adjustments and procedures for operation and
maintenance other than those specified herein may result in
hazardous radiation exposure.
