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.
