Troubleshooting
Although service and repair of the Cavitron Touch Ultrasonic
Scaler should be performed by DENTSPLY personnel, the
following are some basic troubleshooting procedures that will
help avoid unnecessary service calls. Generally, check all
lines and connections to and from the System. A loose plug
or connection will often create problems. Check the settings
on the System's controls.
