Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
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.
No or dim illumination / lamp fault
HighSymptoms: No light output, dim or flickering light, lamp-hours alarm, colour shift.
Root cause: Xenon / LED lamp at end of life, a lamp power supply fault, or a light-cable fault.
Poor video image
HighSymptoms: Noisy, dark, discoloured or out-of-focus image, dropouts, no image.
Root cause: Camera head / coupler fault, a camera-cable fault, or a CCU / video-processor fault.
White-balance / colour fault
MediumSymptoms: Cannot white-balance, persistent colour cast.
Root cause: Camera head sensor drift, a dirty coupler, or the light source colour temperature.
Overheating / fan fault
LowSymptoms: Thermal shutdown, loud fan, hot exhaust.
Root cause: Failed or clogged cooling fan.
Output / connector fault
LowSymptoms: Signal only on one output, connector damage, HD/SDI dropout.
Root cause: Worn video output connector or an output board 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 low laser output
- Measure output at the delivery device with a laser power meter against the setting.
- Fit a known-good delivery fibre / handpiece / applicator.
- Confirm the cooling system runs and the coolant is at level and clean.
- Check the key switch, door interlock and footswitch are satisfied.
- Escalate a confirmed laser-module / lamp / diode-bar or driver fault to the OEM; recalibrate power after any module work.
Symptom: Cooling / thermal shutdown
- Confirm the cooling fans / pump run and the airflow is clear.
- Check the coolant level and replace the coolant filter.
- Let the unit cool and restart.
- Clean the air filters / vents.
- Monitor for recurrence during a treatment.
Symptom: Burn marks at the fibre / handpiece tip / intermittent output
- Inspect the delivery fibre / applicator and its connector for damage or contamination.
- Re-cleave or replace the fibre.
- Clean the output optics per the manual.
- Confirm the applicator is recognised by the console.
- Re-measure output with a power meter.
Symptom: Will not fire / key, interlock or footswitch error
- Confirm the key switch is on and the door / remote interlock loop is closed.
- Test the footswitch and its cable.
- Check the aiming beam is present.
- Clear any standby / safety timeout.
- Replace the footswitch or refer the interlock circuit.
