treatment might stop or the unit might restart due to a non-repeating event, such as AC
power surges, or power spikes.
Possible sources of EMI can include, but are not limited to, cellular phones, radio
transmitters, motors, telephones, and lamps, as well as other medical equipment, such as
electrosurgical products and defibrillators. EMI may be conducted through the AC power
lines. Restrict the use of this equipment in the vicinity of the ClosureRFG generator.
If interference affects other equipment in the treatment area, move the other equipment
or the ClosureRFG generator to a different location. Move the ClosureRFG generator cord
and the catheter away from the susceptible equipment and its cords and cables.
Biomedical Department Inspection and Power
Output Test
Note:
The ClosureRFG radiofrequency generator performs an internal calibration during
each start-up. No calibration is needed, and there are no internal adjustments to the RF
power generator.
Covidien has created a Biomedical Department Inspection Procedure for the testing of the
ClosureRFG radiofrequency generator. This procedure outlines setting up the ClosureRFG
generator in concert with an ESU analyzer to verify temperature measurement, power
output, and measurement of impedance.
A test cable from Covidien is available for this purpose. Please contact Covidien Customer
Service for information on obtaining the Biomed Test Cable. (TL100-119-02 Cable,
Biomed Test).
Set-up Procedure
• Check the ClosureRFG generator case exterior. The case exterior must have no visible
damage (e.g., dents, scratches, peeling paint).
• The touch screen must have no visible foreign material or damage.
• Inspect all external connectors/receptacles for bent pins, foreign objects, a damaged
case and/or improper fit.
• The AC power cord must have no obvious physical defects or damage.
• Connect the ClosureRFG generator to the appropriate AC power supply and turn on
main power. Wait until the ClosureRFG generator completes its POST.
• Attach the test cable to the ClosureRFG generator.
• The front panel parameters should be:
Temperature: ~23° C (ambient temperature)
Impedance: 1999 Ω
Power: 0 W
