Functionality
The HF device is controlled by a microprocessor and converts the mains
voltage into a high-frequency alternating current for monopolar or
bipolar applications.
For descriptions of the individual modes and their areas of application
as well as appropriate instruments, see Section Mode descriptions,
page 31.
3.1.
Monopolar modes
In monopolar operation, the HF device has the following operating
modes:
"Pure" for cutting in low-resistance tissue
"Dry" for cutting with strong haemostasis
"Moderate" for contact coagulation
"Forced" for coagulation with light contact
Instruments can be connected to the multifunction socket

.
3.2.
Bipolar mode
Special instruments are necessary in order to achieve optimal results
using the bipolar method (particularly with minimally invasive surgery).
Advantages of the bipolar method:
The required high-frequency output is only one-fourth of the
output required for the monopolar method.
It is not necessary to apply a neutral electrode to the patient,
which eliminates the associated risks to the patient.
Instruments can be connected to the multifunction socket
