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.
