BP A50 Semi Automatic Blood Pressure Monitor


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.

The Err CUF probably means that the blood pressure cuff isn't properly arranged on the arm. Check that the cuff is around the upper arm 1-2 cm above the elbow. The hose should be near the center of the elbow. Make sure that a rolled up shirt sleeve is not too tight. Next check that the indicator arrow is in the correct range when the cuff is firmly fastened.

Make sure that you are using the correct cuff for the user. There are different blood pressure cuffs (medium, large, wide-range) available for some blood pressure monitors. If the arrow doesn't line up in the indexed range, use a different blood pressure cuff for the unit.

I hope this helps. I used the information about the A&D Medical UA-767 for some of the trouble-shooting details. See https://medical.andonline.com/product/premium-blood-pressure-monitor/ua-767f and click on the Downloads tab to see the manual for this model. (I suspect the Life Source and A&D Medical products are extremely similar.)

Why don't ask at the place you've bought it?
