What to do if my JOYTECH Blood Pressure Monitor shows Er5?
- CChase Payne PhDAug 10, 2025
If your JOYTECH Blood Pressure Monitor displays 'Er5', it could be due to the pressure exceeding 15 mmHg for 3 minutes, potentially caused by a knotted cuff or blocked vent valve. Check the cuff and valve; if the issue continues, contact the manufacturer. Alternatively, it may be caused by a dead battery, in that case replace the battery or connect the power adapter if available.
