WARNING: Do not open the back panel of the RF Generator. This may cause serious
injury and damage to the unit. It will void the warranty. When problems cannot be
resolved by the directions in this troubleshooting section, contact nContact Surgical, Inc.

Action
• Be sure the generator is plugged into a
working electrical outlet.
• Check power switch on back of generator.
• Unplug and check the fuse on the rear
panel. Fuses should only be replaced with
LittleFuse 2183.15, Time Delay (Slo Blo)
rated at 3.15A, 250VAC.
• Check connections to coagulation device
and indifferent, dispersive electrode.
• Ensure device is properly placed on tissue
site.
• Check position of indifferent, dispersive
electrode on patient's back or thigh.
• If problem persists, replace the coagulation
device and indifferent, dispersive
electrode.

Action
• Power unit OFF, then Power ON again.
• Allow generator to run through normal
start-up self-diagnostics.
• If generator returns to Error state and the
problem persists, contact your nContact
Surgical, Inc. representative.
• Depress and release the indicated button
to determine if the button remains stuck.
• Power unit OFF, then Power ON again.
• Allow generator to run through normal
start-up self-diagnostics.
• If generator returns to Error state and the
problem persists, contact your nContact
Surgical, Inc. representative.
• Verify the footswitch is connected to the
front panel of the generator
• Ensure Time is not set to 0.
• Ensure IMP LIMIT error is not detected -
impedance should be within 30 – 500Ω.
• Ensure a coagulation device is connected
to the generator
• Ensure the indifferent, dispersive electrode
is attached to the patient and connected to
the generator
• Check the footswitch by unplugging its
cable from the generator, placing a thumb
over the foot pedal connector then
depressing the pedal. If the footswitch is
functioning properly, air should be expelled
through the connector as the footswitch is
depressed.
• Ensure the cables from the electrodes do
not cross the cables from the ultrasound
probe or other equipment.
• Changing settings on the ultrasound may
alleviate image interference.
• Ensure the indifferent, dispersive electrode
is properly attached.
• Check all connections.
• Clean off any coagulum from the
coagulation device.
• Ensure device is properly placed on tissue
site.
o Reposition the coagulating device
