PART NO.: LTP-1557AKTB-P BNS-OD-C131/A4 PAGE: 4 of 6 LITE-ON TECHNOLOGY CORPORATION Property of Lite-On Only ESD (Electrostatic Discharge) Static Electricity or power surge will damage the LED. Suggestions to prevent ESD damage: Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs. All devices, equipment, and machinery must be properly grounded. Work tables, storage racks, etc. should be properly grounded. Use ion blower to neutralize the static charge which might have built up on surface of the LED's plastic lens as a result of friction between LEDs during storage and handling.
