What causes baseline wander on Mindray Passport 12 Medical Equipment and how to fix it?
- B
  Barbara FriedmanSep 22, 2025
  If you observe baseline wander on your Mindray Medical Equipment, it could be due to several reasons. First, if the patient is moving excessively, try to secure the lead wires and cable to the patient. Second, check if the electrodes are dry or loose; if so, repeat skin preparation and apply fresh and moist electrodes. Lastly, ensure that the ECG filter is set to 'Monitor' mode, as setting it to 'ST' or 'Diagnostic' mode can also cause baseline wander.

What to do if the touchscreen on my Mindray Passport 12 Medical Equipment monitor does not respond?
- W
  William ComptonAug 25, 2025
  If the touchscreen on your Mindray Medical Equipment does not respond, first check if the touchscreen is disabled. Look for a symbol above the [Main Menu] quickkey; if present, press and hold the [Main Menu] quickkey for more than 3 seconds to enable it. If that doesn't work, check the cables between the touchscreen and touchscreen control board, and between the touchscreen control board and main board to ensure they are correctly connected. If the problem continues, the touchscreen control board, the touchscreen itself, or the main board might be defective and require replacement.

Why can't my Mindray Medical Equipment connect to Wi-Fi?
- T
  taylorstaceyDec 1, 2025
  If your Mindray Medical Equipment is unable to connect to the Wi-Fi network, it may be due to an unstable Wi-Fi signal. Verify that the network is available and that the network type is correctly set (e.g., LAN or WLAN). Also, check that the SSID and password of the monitor match those of the wireless AP. Ensure there are no IP address conflicts and that the IP addresses are correctly set. It is also recommended to use a Mindray recommended wireless AP, ensuring it meets the throughput requirements. Verify the AP channel bandwidth is 20 MHz, and that the wireless AP signal strength is no less than -65 dBm where the monitor is located. Check that the signal strength of other Wi-Fi devices at the same channel is no greater than -85 dBm, and that the signal strength of other Wi-Fi devices of ...

What to do if Mindray Medical Equipment fails to review data?
- S
  Sarah RandallSep 12, 2025
  If your Mindray Medical Equipment fails to review archived patient data, it might be due to abnormal patient admitting. Ensure the patient is admitted properly. It could also be due to the SD card being full. Delete unnecessary patient data and remove related alarms, then readmit the patient. If the issue persists, the main board might be defective and need replacement.

Why is the secondary display not working on my Mindray Passport 12?
- A
  Andrew RoblesSep 4, 2025
  If the secondary display on your Mindray Medical Equipment does not function or displays snow or flashing specks, it could be caused by a defective cable or the connector board. Check that the cable between the secondary display and the monitor, the cable between the main board and power management board, and the cable between the power management board and interface board are correctly connected. If the connections are correct, the connector board might be defective and need replacement.
