Lamp failure of xenon light source
The xenon light source has a lamp module containing two xenon lamps. The
second lamp is used as backup lamp. Manually swivel in the backup lamp after
a failure of the first lamp or if the maximum service life of the first lamp of
500h (see chapter "Maintenance intervals" on Page 222) is exceeded. The
backup lamp is in operation if the red segment (3) is lit in button (2).
Manual switching to the backup lamp
• Turn off the suspension system at the power switch before switching to
the backup lamp.
• Press the button (4) to open the lamp module.
 The lamp module is slightly ejected.
• Pull out the lamp module (1) as far as it will go. Turn knob (2) through
180° until it snaps in place.

This moves the backup lamp into the illumination beam path.
• Push the lamp module (1) all the way back into the lamp housing.
• Turn on the suspension system at its power switch.
• In case the backup lamp is defective and an exchange of the lamp module
is not possible, please proceed with an external surgical lamp.
Failure of backup lamp
• If you work with the backup lamp and this lamp fails during a surgery, the
lamp module of the xenon light source must be exchanged, see Page 226.
CAUTION Risk of burns!
In the event of overheating, the lamp switches off automatically. When the
lamp has cooled down, it automatically switches on again.
If the microscope is positioned unattended above the patient, the patient can
be burnt due to the produced heat.
• Immediately activate the backup lamp after a lamp failure or switch off
the light source completely.
• Check if the light source is switched off before leaving the device unat-
tended.
