R08DS0001EJ0100 Rev.1.00 Jul 26, 2010 Page 6 of 7 NX8349TB SAFETY INFORMATION ON THIS PRODUCT Warning Laser Beam A laser beam is emitted from this diode during operation. The laser beam, visible or invisible, 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. Caution GaAs Products This product uses gallium arsenide (GaAs). GaAs vapor and powder are hazardous to human health if inhaled or ingested, so please observe the following points. • Follow related laws and ordinances when disposing of the product. If there are no applicable laws and/or ordinances, dispose of the product as recommended below. 1. Commission a disposal company able to (with a license to) collect, transport and dispose of materials that contain arsenic and other such industrial waste materials. 2. Exclude the product from general industrial waste and household garbage, and ensure that the product is controlled (as industrial waste subject to special control) up until final disposal. • Do not burn, destroy, cut, crush, or chemically dissolve the product. • Do not lick the product or in any way allow it to enter the mouth. Caution Optical Fiber A glass-fiber is attached on the product. Handle with care. R08DS0001EJ0100 Rev.1.00 Jul 26, 2010 • When the fiber is broken or damaged, handle carefully to avoid injury from the damaged part or fragments.
