NCODER
When the unit is switched on by the electronic mains switch, all the power levels are automatically put at the minimum level.
Whether the previous power levels are to be changed, four incremental encoders can be used to control the output power
level and preset new values.
The four encoders provide fine control of the power, each for one of the available output current (MONOPOLAR CUT,
MONOPOLAR COAG, BIPOLAR CUT, BIPOLAR COAG).
The use of the incremental encoder in the output level control allows to increase or decrease the output power level by steps
as low as one single watt.

Pedal Connector
This is the connection point for the double pedal switch. The double pedal switch is allowed to control the
emission either of the monopolar current or of the bipolar current depending by the operative condition. By the
Cut (yellow) pedal switch the emission of the CUT current is controlled and by the Coag (blue) pedal switch
the emission of the COAG current is controlled.
Monopolar Patient Plate Connector
This is the connection point for the Patient Plate.
The Patient Plate connection is continuously monitored, and
should it fails, the current emission of the unit is immediately
stopped.
Monopolar Handpiece Connector
This is the connection point for the handpiece with double hand-
switch.-By the yellow key the emission of the monopolar CUT
current is controlled and by the blue key the emission of the
monopolar COAG current is controlled. The switch electric
resistance is continuously monitored and the function of control
of the emission stopped when the resistance value exceeds the normal value.
Bipolar Forceps
This is the connection point for the bipolar forceps.

The following indicator sounds are emitted during the HF power delivery:
-
A continuous sound at 2500 Hz frequency during Cut or Cut/coag current
delivery.
-
A continuous sound at 1250 Hz frequency during Coag current delivery.
The acoustic level of the two above said tones can be chosen by the operator . (Please refer to section 4.3.6 )

The four Indicator Lights are used for indicating various conditions of the unit's current emission, as follows:
MONOPOLAR CUT
Illuminate when the unit emits Monopolar Cut current or Monopolar Cut/Coag current. The light's
color is yellow.
MONOPOLAR COAG
Illuminate when the unit emits Monopolar Coag current. The light's color is blue.
BIPOLAR CUT
Illuminate when the unit emits Bipolar Cut current. The light's color is yellow.
BIPOLAR COAG
Illuminate when the unit emits Bipolar Coag current.The light's color is blue.

A modulated sound at 2500 Hz is emitted when the OC alarm is on. The sound level of this warning signal is fixed at about
70 dBA and it is not adjustable by the operator.

Four red LEDs are provided for the unit's signal warning, as follows:
READY
Illuminates when the unit is plugged to the mains, the mechanical mains-switch is on and the electronic mains
switch is off. (The mechanical mains-switch is located in the rear panel of the unit).When this LED is illuminated the
equipment is ready to be put in service by the mains electronic switch.
MONOPOLAR OC
Illuminates when there is a failure in the connection of the monopolar patient plate (see 4.3.5). When
this LED is illuminated the emission of the monopolar current is inhibited.
MONOPOLAR OVH
Illuminates when the electronic power generator's temperature exceeds the normal range and the
electronic circuit operation is no more safe. This can happen when the emission time exceeds the allowed duty cycle ( 10
