How to fix a blank display on my AND UA-767 Plus BT?

If nothing appears on the display of your AND Blood Pressure Monitor, even when powered on, the batteries may be drained. Replace all batteries with new ones. Alternatively, the battery terminals might be incorrectly positioned. Reinstall the batteries, ensuring the negative and positive terminals match the markings in the battery compartment.
