(9) Eye Safety

-The International Electrical Commission (IEC) published in 2006 IEC 62471

”2006 Photobiological safety of lamps and lamp systems ” which includes LEDs within its scope.

When sorting single LEDs according to IEC 62471, almost all white LEDs can be classified

as belonging to either Exempt Group (no hazard) or Risk Group 1 (low risk).

-However, Optical characteristics of LEDs such as radiant flux,

spectrum and light distribution are factors that affect the risk group determination of the LED,

and especially a high-power LED, that emits light containing blue wavelengths,

might have properties equivalent to those of Risk Group 2 (moderate risk).

-Great care should be taken when directly viewing an LED that is driven at high current,

has multiple uses as a module or when focusing the light with optical instruments,

as these actions might greatly increase the hazard to your eyes.

-It is recommended to regard the evaluation of stand-alone LED packages as a reference

and to evaluate your final product.

(10) This product is not designed for usage under the following conditions.

If the product might be used under the following conditions, you shall evaluate its effect

and appropriate them. In places where the product might:

-directly and indirectly get wet due to rain and/or at place with the fear.

-be damage by seawater and/or at place with the fear

-be exposed to corrosive gas (such as Cl2, H2S, NH3, SOx, NOx and so on) and/or at place with the fear.

-be exposed to dust, fluid or oil and/or at place with the fear.

(8) Recommended soldering Condition (This product is not adaptable to reflow process.)

-For manual soldering

Please use lead-free soldering.

Soldering shall be implemented using a soldering bit at a temperature lower than 350C,

and shall be finished within 3.5 seconds for one land.

No external force shall be applied to resin part while soldering is implemented.

Next process of soldering should be carried out after the product has return to ambient temperature.

-For soldering correction

Regarding soldering correction, above conditions shall be applied.

Contacts number of soldering bit should be within twice for each terminal as a correction.

* Citizen Electronics cannot guarantee if usage exceeds these recommended conditions.

Please use it after sufficient verification is carried out on your own risk if absolutely necessary.
