Handling Static-Sensitive Circuits/Devices:
dling the Ultrasonic switch, the technician should follow
these guidelines to reduce any possible electrostatic charge
build-up on the technicians body and the electronic part.
1. Always touch a known good ground source before handling the
part. This should be repeated while handling the part and more
frequently after sitting down from a standing position, sliding
across the seat or walking a distance.
2. Avoid touching electrical terminals of the part unless making connections.
3. DO NOT open the unit cover until it is time to calibrate.
