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.
