OPMI®: setting the lamp brightness
This function permits you to set the lamp brightness.
In the basic mode, the lamp brightness currently set is shown in the upper
display field.
The middle display field remains empty and the associated keys "∇" and
"Δ" have no function.
If the suspension system is equipped with a second halogen lamp
housing, the brightness currently set for the second lamp is displayed in
the middle display field.
Adjusting the settings
Keys "∇" and "Δ" allow you to change the lamp brightness.
– Check that the lamp brightness can be varied and that brightness var-
iation has an effect on the surgical field illumination. Perform this
check across the entire control range. The brightness can be adjusted
in the following ranges:
– Halogen: 0.5 ... 10 in steps of 0.5
– Xenon: 0.5 ... 10 in steps of 0.5
Warning!
Too much light intensity (brightness setting is too high) or excessive radi-
ation exposure times may lead to retinal injury in the patient's eye.
• Adjust the illumination intensity as required for the selected type of il-
lumination and the radiation exposure time. You will find the values
recommended by Carl Zeiss in the table "Maximum radiation expo-
sure times" on page 29.
Acoustic signals for the Superlux Eye light sourcr
– One beep is emitted when the suspension system is switched on. This
beep is only used as a check for the loudspeaker function.
– If several successive beeps are emitted and the xenon lamp is lit when
the system is switched on, this indicates a malfunction of the light
source.
• Attach a sign to the system stating it is out of order and contact our
service representative.
Path: The basic mode is automatically displayed after the instrument has
been switched on.
