Regulatory Requirements

• Passes FCC B and worldwide analogous emission limits

when assembled into a mouse with unshielded cable

and following Avago recommendations.

• Passes EN61000-4-4/IEC801-4 EFTB tests when

assembled into a mouse with shielded cable and

following Avago recommendations.

• UL flammability level UL94 V-0.

• Provides sufficient ESD creepage/clearance distance

to avoid discharge up to 15 kV when assembled into

a mouse according to usage instructions above.

• For eye safety consideration, please refer to the

technical report available on the web site at www.
