Checklist
Always check the following points before surgery (without the patient!):
Note:
After switching on, the suspension system automatically performs a self-
test which takes approx. five seconds. A short beep indicates the comple-
tion of the self-test.
Xenon illumination system
– The xenon lamp including the backup lamp is intact.
– The xenon illumination is on and the green indicator lamp is lit.
Note:
If the first lamp has failed and the backup lamp is in use (red segment
in the switching knob lights up), make sure to have a backup lamp
module ready at hand as a precaution.
Warning!
The xenon lamp has a limited service life of 500 h.
If used beyond its maximum service life, the xenon lamp may explode.
Change the xenon lamp in good time.
Please note the following guidelines - example:
– If operated for 4 hours/day on 5 days/week, the lamp needs to be ex-
changed after 25 weeks maximum.
– If operated for 8 hours/day on 5 days/week, the lamp needs to be ex-
changed after 12 weeks maximum.
Lifting column
– The function of the upward/downward movement is OK.
– Check that the surgical microscope is in a convenient position and that
you have set the optimum ergonomic working height of the stand via
the lifting column.
Balance setting
– Check that the suspension arm has been properly balanced. When
the release button at the surgical microscope is pressed, the effort re-
quired to move the arm up or down is the same.
Limitation of downward travel
– Check that the minimum working distance (height) from the surgical
field has been set using the adjustment screw for limiting downward
travel.
