What to do if nothing appears on my A&D UM-102 display?

If nothing appears on the display of your A&D Blood Pressure Monitor, even when you turn it on, the batteries may be empty. Replace all batteries with new ones. Also, ensure the battery polarities are correctly aligned. Reinstall the batteries, matching the positive and negative ends to the markings in the battery compartment.
