System Troubleshooting
WARNING: TO AVOID ELECTRIC SHOCK, DO NOT REMOVE THE CASE COVER FROM THE GENERATOR OR THE TRANSDUCER. THERE ARE
NO USER-SERVICEABLE PARTS INSIDE ANY OF THESE COMPONENTS.
Mechanical Limit
Mechanical limit light illuminated and pulsing audible alarm activated.
Causes
Possible causes are: Loose Probe to Transducer connection, Cracked or Damaged Probes, Defective Transducer or Overload condition at
Probe tip.
Reset
To reset Mechanical Limit Alarm, release Footswitch. Depress Footswitch again. If Mechanical Limit Light and Audible Alarm sounds, refer to
Troubleshooting Chart.
CAUTION: Ultrasonic energy is inhibited if excessive physical force is applied to the probe; use only enough force to guide the probe to
the removal site and to advance the probe through the tissue. Do not force the probe; allow the ultrasonic action to
do all tissue cutting or coagulation.
Electrical Fault
Electrical fault light illuminated and steady audible alarm activated.
Causes
Possible causes are: Patient Cable or Transducer disconnected, Faulty Transducer, Cable or Generator, or overheated Probe.
WARNING: IF ELECTRICAL FAULT INDICATOR ILLUMINATES AND/OR ELECTRICAL FAULT ALARM SOUNDS, IMMEDIATELY TURN POWER
SWITCH (REAR PANEL OF GENERATOR) TO THE OFF POSITION. REMOVE PROBE FROM SURGICAL SITE. DO NOT TOUCH
METALLIC PARTS OF TRANSDUCER, PROBE OR GENERATOR WHILE FAULT IS INDICATED.
Reset
To reset Electrical Fault Alarm, switch Ready/Standby switch to STANDBY. Turn Main Power On/Off switch to OFF. Refer to Troubleshooting
Chart and go through ALL steps given. Switch Main Power On/Off switch to ON and Ready/Standby switch to READY. Depress Right
Footswitch. If Electrical Fault Alarm activates again, DISCONTINUE USE, REPLACE ENTIRE SYSTEM WITH BACKUP, SET UP AND TEST BACKUP
