CAUTION- use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure. There are no user serviceable parts in this product.
When proper power is applied to this product, Laser radiation will be emitted from the optical fiber.
Important Notes:

T
he maximum ratings mean the limitation over which the laser should not be operated even instant time.
Do not clean the fiber connector when the diode is in operation. The laser should be off when plugging or un-plugging the connector.
To protect the laser diode from damage due to static electricity (ESD), please follow proper ESD handling precautions.
Do not pull or fold the fiber. The fiber is very fragile and easily broken. Avoid handling the fiber by the rubber “boots” of the black
housing and connector ends of the pigtail.
5. To ensure safe operation use only with a suitable power source that complies with the pertinent requirements for laser systems as
specified in IEC-60825-1 “Safety of Laser Products.”
