11 Safety Checks
At least every 24 months, the following checks and tests must be performed on the system (max-
ium, maxium with maxium Beamer) by qualified persons who have the necessary training, knowl-
edge and practical experience to carry out such work properly, responsibly and independently. If
the maxium is used in conjunction with a maxium Beamer, then the Beamer must be checked as
well. An appropriate report form can be obtained from Gebrüder Martin. Just contact the Martin
Service hotline.
A: Visual inspection and functional checks
1. Rating plate and label legibility: All information provided on the maxium’s and (if applicable) the
maxium Beamer’s rating plate must be clearly legible, as well as the rear-side labels, especially
the nominal value information for the device fuses located in the unit’s power supply socket. On
the maxium Beamer, the information concerning the permitted pressure range provided next to
the gas inlet must be clearly legible.
2. A copy of the Operating Instructions must be available for the current version of the system.
Updated manuals can be obtained through the Martin Service Center.
3. Enter the software version number (V X.XXX), which is indicated on the initial screen displayed
upon switching on the unit, in the report form. Pay attention to potential error messages during
the self-test.
4. Check the proper functioning of both screen illumination lamps (uniform illumination of the
screen). Check symbols and pictograms for clarity and correct color rendition (blue and yellow).
5. Visual inspection of all connectors: Check the HF connecting sockets M1, M2, B1 and B2 for
potential damage or defects. On the maxium’s rear panel, check the footswitch sockets, the
equipotential bonding pin and the maxium Beamer connecting socket for potential damage and
firm seat. Disconnect the power supply cable from the unit’s power supply socket and check
the socket for potential damage and firm seat. On the maxium Beamer’s rear panel, check the
socket for the connecting cable to the maxium unit for potential damage and firm seat. Check
the gas inlet, decompression pin and equipotential bonding pin for firm seat. On the Beamer’s
front panel, check the gas outlet for potential damage and firm seat.
6. Check the cables of all reusable accessories used with the unit(s) for insulation and plug dam-
age, especially at the cable ends where stress tends to be high.
7. With the unit turned on, check the sealed buttons (membrane switches) on the maxium’s panel
for proper functioning. Upon operating a channel selector button, the red frame must jump to
the channel’s Power field if the channel has already been selected, or this action selects the
channel in the first place. Check all eight channel selector buttons. Also, verify that upon press-
ing the MENU button, the (bar-type) selection cursor is displayed on top of the list on the right
side of the display (first item highlighted).
8. Functional check of the rotary switch and its backlighting system: Upon selecting a cutting
channel, the backlight must be yellow, and if you select a coagulation channel, the backlight
must be blue. Operating the MENU button must change the color of the backlight ring to white.
Rotate the switch to verify that the power value indicated for the selected channel can be
changed in this way. Press the switch to verify that the axial pushbutton function (“axial click”)
