Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Illumination failure or dim / uneven light
HighSymptoms: No or dim light, sudden loss during a procedure, colour shift, uneven field.
Root cause: Xenon lamp module at end of life, its igniter / power supply, or (LED models) the LED engine / driver.
Suspension / AutoBalance / swing-arm drift
HighSymptoms: Head drifts, AutoBalance fails, arm will not hold after draping or an accessory change.
Root cause: Balance drive or the magnetic brakes; re-balance after any accessory change.
Motorised zoom / focus / XY fault
MediumSymptoms: Zoom, focus or XY will not run or is erratic from the handgrips, mouth switch or foot control.
Root cause: Drive motor, a control, or cabling.
System error in the data-injection / touchscreen display
HighSymptoms: Error message in the eyepiece data injection or on the touchscreen, function inhibited.
Root cause: An internal subsystem fault - acknowledge via the handgrip pushbutton or touchscreen; if it will not clear, service is required.
Integrated video / fluorescence / digital-visualisation fault
LowSymptoms: No or poor video, fluorescence mode not working, digital (Artevo) image fault.
Root cause: Camera / fluorescence module or a video / processing fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No or dim light
- Switch to the onboard spare lamp if the model has one.
- Unplug, let the lamp cool and replace the lamp module.
- Check the igniter / power-supply output and the mains fuse.
- Confirm the lamp is seated.
- Verify even, full-brightness illumination.
Symptom: Head will not hold position / system error
- Re-balance / run AutoBalance for the current accessory load - never over the operating field.
- Acknowledge any data-injection / touchscreen error via the handgrip pushbutton or touchscreen.
- If the error will not clear, attach an out-of-order sign and contact the ZEISS service representative.
- For a drive fault, set the emergency switch to manual mode and operate zoom/focus by hand.
- Do not use for surgery until cleared.
