The warranty period starts on the date of purchase. Service under this warranty must be obtained by returning the unit (defective component) to Compu-Bias, or to an approved Compu-Bias distributor. This warranty does not guarantee serviceability in or for any application and will not include any incidental or consequential damage or loss caused either directly or indirectly.
