What to do if my A&D UA-767NFC Blood Pressure Monitor display is blank?

If nothing appears on the display of your A&D Blood Pressure Monitor, even when you turn it on, the batteries may be drained. Try replacing all the batteries with new ones. Also, ensure that the battery terminals are correctly aligned with the positive and negative markings inside the battery compartment. Reinstall the batteries, matching the terminals as indicated.
