What does error 5 on my microlife blood pressure monitor mean?

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.

See page 1 of the manual above with phone numbers to call for whatever country you live in and ask you question. There was not an error 4 in this manual. You might want to call your Doctor's office, and inquire. Perhaps batteries are going bad.

Turn it off, Hold down the "M" button until "CL" appears and press "M" while "CL" is flashing.

Repeat measurement keeping arm still. If inflation of the cuff takes too long, the cuff is not correctly seated or the hose connection's not tight. Check connections and repeat
