Covered by Patent Numbers 5262779 and 5272481.
WARNING – LIFE SUPPORT APPLICATIONS POLICY – SPT products should not be used within Life Support Systems without the specific
written consent of SPT. A Life Support System is a product or system intended to support or sustain life which, if it fails, can be reasonably
expected to result in significant personal injury or death.
Signal Processing Technologies believes that ultrasonic cleaning of its products may damage the wire bonding, leading to device
failure. It is therefore not recommended, and exposure of a device to such a process will void the product warranty.
