For most Microlife blood pressure monitors, the error 3 indicates that the unit cannot reach the proper pressure in the cuff to start the test. If replacing the batteries doesn't work, check that the cuff is properly plugged into the socket on the monitor. Next you may need to replace the cuff. There may be a leak in the cuff or the hose between the cuff and the socket. Microlife sells replacement blood pressure cuffs here: https://www.microlife.com/consumer-products/blood-pressure/cuffs-and-supplies . These cuffs fit all of their devices except for the wrist versions.

I hope this helps.
