Suspension systems
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.
The suspension system is equipped either with halogen or xenon illumi-
nation.
Lamp brightness (halogen, xenon)
•
Check the brightness control for correct function:
– A beep sounds after power-on of the system, and stops when the
xenon lamp has ignited correctly and if no other error has oc-
curred.
– If the beep does not stop, do not continue to operate the system.
• Check that the lamp brightness display shows the minimum level (0.1)
after power-on of the system.
• Change the lamp brightness across the entire control range, and
check that brightness variation has an effect on the surgical field illu-
mination (bright/dark).
Halogen illumination
–
The halogen illumination has been switched on and the green indica-
tor lamp(s) is (are) lit.
– The halogen lamps including the backup lamps are intact, i.e. the yel-
low indicator lamp(s) is (are) not lit.
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.
Balance setting
–
Check that the suspension arm has been properly balanced. When
the release button on the surgical microscope is pressed, the effort re-
quired to move the arm up or down must be the same.
Limitation of downward travel
–
The minimum working distance (height) from the surgical field has
been set using the adjustment screw for limiting downward travel.
