LAVA's calcul ations take into account the infant mortality and constant failure and wearout rates of the components as well as of the finished products. LAVA's testi ng excepted such variances as: mishandling of finished product, shipping damage, and damage caused during installation. LAVA's MTBF rates were ascertained as a mix of actual product experience balanced with predictions made by analyzing known factors for newer products. MTBF ratings are provided as a service to our customers to help in planning service level agreements, etc. LAVA Computer MFG Inc. 's Limited Lifetime Warranty will be the deciding factor in all warranty issues.
