Caution
GaAs Product
Caution
Optical Fiber
A laser beam is emitted from this laser diode during operation.
The invisible or visible laser beam, directly or indirectly, may cause injury to the eye
or loss of eyesight.
Do not look directly into the laser beam.
Avoid exposure to the laser beam, any reflected or collimated beam.
The product contains gallium arsenide, GaAs.
GaAs vapor and powder are hazardous to human health if inhaled, ingested or swallowed.
Do not destory or burn the product.
Do not crush or chemically dissolve the product.
Do not put the product in the mouth.
Observe related laws and company regulations when discarding this product.
The product should be excluded from general industrial waste or household garbage.
A glass-fiber is attached on the product. Handle with care.
When the fiber is broken or damaged, handle carefully to avoid injury from
the damaged part or fragments.
