Accessories
WARNING
Mechanical stress
Do
not apply excessive bending, straining, or squeezing force to any cords. It may cause
malfunction.
CAUTION Non-compatible accessories and accessory damage
The electrosurgical generator shall only be used with compatible accessories. When connecting
accessories (cords, electrodes, HF instruments) avoid output settings where the maximum
output voltage of the electrosurgical generator may exceed the rated accessory voltage (refer to
“Mode characteristics”, “Output characteristics” in the Appendix of the ins
truction for use, and the
instruction manual of the accessory). For a list of compatible neutral electrodes, refer to
“Specifications” in the Appendix of the instruction for use.
Before use, the electrosurgical unit and accessories must be examined for damage. All
communication cables and its plugs must be free of scratches and cracks. Cables and
accessories with damaged insulation or connections must not be used.
Electric shock
WARNING Grounding failure
To prevent the risk of electric shock, the housing of the electrosurgical unit must be grounded.
Always connect the power cord plug to a properly grounded wall outlet. Do not use a
3
-pin / 2-pin adapter, as it can impair safe operation of the unit.
WARNING User shock
To prevent user shock, malfunction
and damage of the electrosurgical unit, keep liquids away
from all electrical equipment.
When taking measurements or troubleshooting of the electrosurgical unit, take appropriate
precautions, such as using isolated tools and equipment, using the “one han
d rule,” etc.
CAUTION Injury during servicing
When the housing is opened, there is a danger of electric shock. The unit must only be serviced
by
authorized technicians.
Burns
WARNING User
The maximum output voltage characteristics of the electrosurgi
cal generator are shown in the
diagrams in “Output characteristics” in the Appendix of the instruction for use. When setting the
power level, first set it to a low level and increase it gradually. If the output is initially set to a high
level, the electro
de’s insulation may be damaged and cause user and /
or patient burns.
However, certain modes may present an unacceptable risk at low output power settings. For
example, with the PulseCut fast mode or PulseCut slow mode, the risk of an excessive thermal
effect rises if the output power setting is too low. Therefore, it is recommended that you perform
basic testing before using the electrosurgical generator. If the instruction manual of the HF
instrument to be used stipulate a rated voltage, the output should
be set so that it does not
exceed that voltage.
High frequency, high voltage signals that can cause severe burns are present in the
monopolar
/ bipolar sockets described in this maintenance manual. Take appropriate precautions
when testing and troublesho
oting this area of the electrosurgical unit.
