It is recommended that a wristband, conductive mat or anti-electrostatic glove is used when handling the LEDs. All devices, equipment (e.g. soldering iron points) and machinery must be properly grounded. SAFETY PRECAUTIONS FOR HANDLING HIGH BRIGHTNESS LEDs Invisible Laser Radiation : Avoid direct eye exposure to UV light Please refer to European Standard BSEN 100015-1 1992 for further information. © Marl Optosource 2000 Datasheet Reference 29/99 Issue 01 Marl Optosource • Fax: +44 (0)1229 580012 • email: [email protected] • website: www.optosource.com • Telephone +44 (0)1229 582430
