Troubleshooting
Technical Assistance
To obtain technical assistance, contact Covidien Customer Service or a local distributor.
See Chapter
10,
Service & Maintenance
for contact information.
The following sections suggest ways to troubleshoot three levels of problems: no power,
RF treatment (procedure and catheter) problems, and generator functionality errors.
Generator Fails to Power On
If the ClosureRFG radiofrequency generator fails to power on, check for obvious
conditions that may have caused the problem:
• Check the ClosureRFG generator for visible signs of physical damage.
• Check the power cord. Replace the power cord if you find exposed wires, cracks,
frayed insulation, or a damaged connector.
• Verify that the wall outlet is supplying power.
Refer to Chapter
10,
Service & Maintenance
for more information.
RF Treatment Difficulties
During RF treatment, the ClosureRFG radiofrequency generator monitors the catheter’s
parameters (temperature, impedance, and RF power). Should one of these measurements
be too high or too low, the ClosureRFG generator may stop RF treatment, sound an alarm,
display an alarm message, and/or and flash this icon:
The following tables describe some situations that the operator might encounter. They do
not include every possible situation that might occur.
Note:
For more information, please refer to the catheter’s instructions for use.
