•
Do not apply the neutral electrode above implants or other metal parts, nor above bone protrusions
or scarred tissue. If necessary, prepare the application site by cleaning and degreasing it; strong hair-
growth is to be removed. For removal do not use substances (e.g. alcohol) that desiccate the skin.
•
Do not use adhesive electrodes whose gel layer is injured, nor adhesive electrodes that have been
detached. 2

degree burns might result. The cable clip for the connection of the adhesive
electrode must cover the gel-free connector straps so that they cannot come into contact with the
patient. Make sure that the cable clip and the connector straps match.
•
For removal of the neutral electrode, do not pull at the cable or the connector strap. Quick removal of
adhesive electrodes may hurt the skin.
•
When using a Baby, a capacitive, or a Twin Pad II neutral electrode, it is mandatory to make the
corresponding selection in the sub-menu.
An explanation for better understanding of these rules is provided in section 5.1 “Risks from Stray
Currents”, page 17, and in section 5.2 “Risks from Current Concentration”, page 20.
9.5.2
Gebrüder Martin Patient Control System (PCS)
Correct application of the neutral electrode is of particular importance. The maxium® smart C can be used
both with single-piece and with monitored two-piece electrodes.
The Patient Control System (PCS) by Gebrüder Martin is a tried and tested system for monitoring the
connection and body contact of neutral electrodes. The PCS automatically detects whether a connected
neutral electrode is single-piece or two-piece; user input is not required.
Monitoring of the quality of contact and confirmation via the indicator are possible only in case of split
neutral electrodes (as well as Baby NE or Twin Pad II) Non-split neutral electrodes cannot be monitored;
there is only an insertion detection on the device that informs the user that an instrument is connected.
The status of the neutral electrode is indicated by a light next to the NE
connection socket, as well as in the lower left corner of the screen. If no neutral
electrode is connected, the light at the socket will be flashing red, while the
screen shows the representation of a red neutral electrode, and next to that an
indicator representing the application state of the neutral electrode as a variable
signal (only in case of split preselection of a neutral electrode). This indicator can
be shut off if desired, see section 10.6.4 “Neutral electrode”, page 65. In this
condition no monopolar HF current can be activated. When an attempt is made to
activate an HF current, an intermittent acoustic warning signal is sounded and a
message displayed in the status line of the screen.
Upon connection of a two-piece neutral electrode that adheres correctly to the
patient's skin, after a short run-in the color of the status indicator light next to the
NE socket will change to green. The representation of the NE on the screen will
change to green. The pointer of the indicator is now in the green field. Now
monopolar HF currents can be activated, too.
