How to troubleshoot a GE Corometrics 250cx Medical Equipment monitor with static noise?
- H
  Hector LangSep 2, 2025
  To troubleshoot static noise on the ultrasound signal of your GE Medical Equipment monitor, ensure you are using GE-approved ultrasound transducers and not refurbished ones. Keep sheets and gowns off the transducer, and avoid holding it with your hand. If the fetus is active, reposition the transducer and wait a few seconds before moving it again. The transducer itself may be defective and need checking or replacement. Maternal movement can also cause static.

Why does my GE Medical Equipment recorder flash on and off?
- M
  Maurice ChristianAug 31, 2025
  If the Record Indicator on your GE Medical Equipment monitor's recorder flashes on and off, it may indicate that the paper supply is low or incorrectly loaded. Try installing a new pack of GE-approved paper. It could also be due to the paper-low photosensor being out of calibration, requiring a photosensor check. Alternatively, the paper-low photosensor cable might be disconnected or the photosensor defective, needing reconnection or replacement.

What to do if my GE Corometrics 250cx Medical Equipment monitor doesn't record contractions?
- B
  Brandon PottsAug 27, 2025
  If the TOCO transducer isn't recording contractions on your GE Medical Equipment monitor, first ensure the transducer is securely connected to the monitor unit and properly positioned on the patient. If the UA reference range is exceeded, loosen the belts or remove the transducer, press the UA Reference button, and re-apply the transducer without over-tightening the belt. Ensure maternal contractions exist. If the issue continues, the TOCO transducer may be defective and require checking or replacement.

What to do if my GE Corometrics 250cx monitor displays CHECK CUFF message?
- J
  Juan JoyceAug 26, 2025
  If the CHECK CUFF message appears on your GE Medical Equipment monitor, reposition the cuff and ensure it's properly tightened. Restrict patient limb movement. Make sure the hose is firmly attached to the monitor. Verify that an adult cuff is being used. If the problem continues, the NIBP board may be defective and require replacement.
