Generator Service Manual
›
The Generator supplies up to 50 Watts of Radiofrequency energy at 460 kHz under power,
voltage, or temperature control while continuously monitoring and displaying actual
power and voltage delivered, measured probe temperature(s), time of power duration,
and measured impedance. The use of a dispersive return electrode is specified in the
accompanying IFUs of probes and cables.
The Generator is also intended to stimulate nerve cells by delivering low-frequency pulses in
either voltage or current controlled modes to aid in probe placement.
The Generator is rated as Class 1, Type CF (rated for continuous operation) as per IEC-
60601-1:2005.
Caution!
Rx Only: Federal (U.S.A) law restricts this device to sale by or on the order of a physician.
3 Warnings and Precautions
The safe and effective use of RF energy is highly dependent upon factors under the control of
the operator. There is no substitute for a properly trained operating room staff. It is important
that the operating instructions supplied with the Generator be read and understood before use.
3.1 Warnings
›
Read before use:
Read the User Manual and refer to this Service Manual for additional
information where necessary.
›
Improper line voltage selection may cause malfunction or damage to the instrument:
The
Voltage Selector and Fuse Drawer must BOTH be set to the same voltage. They are located
on the rear panel of the instrument (the fuse drawer is located in the power entry module).
An improper voltage setting may result in Generator malfunction and potential instrument
damage. The Voltage Selector is factory set and should not be changed by the user. (V4.1
and older units).
›
Risk of Electric Shock:
To avoid risk of electric shock, this equipment must only be
connected to supply mains with protective earth.
›
Risk of Fire:
•
Do not use in the presence of flammable anesthetics, other flammable gases, near
flammable fluids (such as skin prepping agents and tinctures), flammable objects or
with oxidizing agents. Observe appropriate fire precautions at all times.
•
Do not use this device in oxygen-enriched atmospheres, nitrous oxide (N
2
O)
atmospheres, or in the presence of other oxidizing agents.
›
Risk of RF burns to the patient:
•
While using this device during a procedure, the patient should not be allowed to
come into direct contact with grounded metal objects such as surgical table frame,
the instrument table, etc. The use of antistatic sheeting is recommended for this
purpose.
