Olympus CV-190
Olympus · Model CV-190
Dual Focus - A unique OLYMPUS innovation based upon an innovative two-stage optical system enables the user to switch between two focus settings. With the simple push of a button, the desired observation mode can be selected: “near mode” featuring ground-breaking resolving power for close mucosal observation or “normal mode” for normal observation. Even in “normal mode”, EVIS EXERA III endoscopes feature an advanced level of resolving power compared to previous generations. Brighter and higher contrast Narrow Band Imaging - NBI in EVIS EXERA III offers a significantly increased viewable distance compared to previous generations. The improved contrast combined with this increased brightness means that NBI opens new possibilities in assisting you in lesion detection and characterisation. Pre-freeze - An exciting new feature, pre-freeze automatically selects the sharpest image when the image is frozen by the user. Improved image processing - New and improved image processing delivers outstanding image quality thanks to reduced noise, reduced halation and improved colour contrast. The result: the optimum in image quality. Waterproof One-touch Connector - The new one-touch Connector enables a one-step connection to the light source and does not require a separate video cable for connection to the video processor. This saves time during procedure setup and dismantling. Variety of signal output options - A whole range of signal output options are available dependent upon the monitor attached to the CV-190, enabling you to achieve the optimum image for the installed infrastructure. 16:9 and 16:10 format is available for HD monitors.
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.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual full PM
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
- Check the lamp-hours counter and replace the lamp module if near / past its rating.
- Inspect the fibre-optic light cable for dark (broken) fibres against a bright light.
- Confirm the lamp strikes (listen / watch) and the fan runs.
- Replace the lamp power supply if the lamp will not strike.
- Verify full brightness with a fresh cable.
Symptom: Poor video image
- Clean the scope lens and coupler and re-white-balance.
- Swap the camera head and cable to isolate head vs CCU.
- Confirm the light source output and cable.
- Try a second monitor / output cable.
- Replace the camera head or refer the CCU as isolated.
