Tip overload can occur during hard tissue removal when applying excessive tip pressure or facing strong tissue resistance,
e.g. from thick cortical bone. This can lead to stalling of the ultrasonic tip. A pulsed audible signal alerts of the stalling and
the ultrasound is deactivated. Release the footswitch briefly and reduce the tip pressure, e.g. by retrieving the ultrasonic tip.
Depress the footswitch again and continue with reduced tip pressure. Consider using higher amplitude setting or reduced
loading if stalling persists.
Electrical Fault Alert
The console monitors the electrical output at all times and alerts in cases where the handpiece is not properly connected to
the console, when an output short or open circuit is detected or electrical safety is compromised.
An Electrical Fault Screen is displayed together with a steady audible indicator. Ultrasound and Irrigation are deactivated.
Requires recycling of mains power switch to re-set.
WARNING 6.1
Immediately suspend operation if Electrical Fault appears on display and/or an Electrical Fault audible
indicator sounds. Remove ultrasonic tip from surgical site. Turn Mains Power OFF. Do not touch any metallic
parts of handpiece, extension, ultrasonic tip or generator while fault is indicated.
