Warranty

This warranty period shall be 90 days after receipt of the product or

1,000 hours operation time whichever is shorter.

Sony Quality Assurance Department shall analyze any product that

fails during said warranty period, and if the analysis results show

that the product failed due to material or manufacturing defects on

the part of Sony, the product shall be replaced free of charge.

Laser diodes naturally have differing lifetimes which follow a Weibull

distribution.

Special warranties are also available.
