(5) Cleaning

· It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs.

When using

other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the

resin or not.

Freon solvents should not be used to clean the LEDs because of worldwide regulations.

· Do not clean the LEDs by the ultrasonic.

When it is absolutely necessary, the influence of ultrasonic

cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition.

Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur.

(6) Static Electricity

· Static electricity or surge voltage damages the LEDs.

It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.

· All devices, equipment and machinery must be properly grounded.

It is recommended that precautions

be taken against surge voltage to the equipment that mounts the LEDs.

(7) Others

· NESR505D complies with RoHS Directive.

· The LED light output is strong enough to injure human eyes.

Precautions must be taken to prevent

looking directly at the LEDs with unaided eyes for more than a few seconds.

· Flashing lights have been known to cause discomfort in people; you can prevent this by taking

precautions during use.

Also, people should be cautious when using equipment that has had LEDs

incorporated into it.

· The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such

as office equipment, communications equipment, measurement instruments and household appliances).

Consult Nichia’s sales staff in advance for information on the applications in which exceptional quality

and reliability are required, particularly when the failure or malfunction of the LEDs may directly

jeopardize life or health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor

control systems, automobiles, traffic control equipment, life support systems and safety devices).

· User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written

consent from Nichia.

When defective LEDs are found, the User shall inform Nichia directly before

disassembling or analysis.

· The formal specifications must be exchanged and signed by both parties before large volume purchase begins.

· The appearance and specifications of the product may be modified for improvement without notice.
