Rectify error
1. If the indicator light is red when a single surface neutral electrode is connected,
check the first two of the sources of error above and remedy the error if neces-
sary.
If the indicator light is red when a dual surface neutral electrode is connected,
check all of the sources of error above and remedy the error if necessary.
2. In case of doubt, remove the neutral electrode and check the condition of the skin
(skin must be shaven and dry).
3. Dispose of the neutral electrode you removed and apply a new neutral electrode
to the patient.
Monitor neutral electrode during
use
If one of the errors above occurs again during use, the neutral electrode indicator light
switches from green to red. If you attempt to activate the monopolar socket when the
indicator light is red, a tone sounds and the error number "2" is displayed.
Eliminate any error if necessary.
Check program settings
Check assignment of the
footswitch/AUTO
START function
Watch the indicator lights of the instrument sockets on your VIO.
Two examples are shown in the following illustration.
Fig. 6-5
How to assign the footswitch to a socket is described on page 60.
How to assign the AUTO START function to the bipolar socket is described on page 60.
Activation of the unit with no knowledge of active settings
If the user does not understand the active settings of the unit, he
can cause the patient accidental tissue damage.
Check the active settings on the display of the unit, after: switch-
ing on the unit, connecting up an instrument, and changing the
program.
Example 1 Example 2
The footswitch indicator light of the
bipolar socket illuminates: The
footswitch is assigned to the bipolar
socket.
In this case, you activate the HF current
of the bipolar socket with the
footswitch.
The AUTO START indicator light illumi-
nates: The AUTO START function is
assigned to the bipolar socket (avail
-
able for the VIO 100 C only).
The COAG current is automatically acti-
vated if you grasp tissue with the bipo-
lar instrument.
