How to fix Dr.Frei Blood Pressure Monitor when no display appears?
If no display appears on your Dr.Frei Blood Pressure Monitor after pressing the START button, it could be due to exhausted batteries. Try replacing the batteries. Alternatively, the batteries might be incorrectly installed or missing. Please check that the batteries are correctly installed.
Why does the cuff on my Dr.Frei M-400A Blood Pressure Monitor keep inflating?
If your Dr.Frei Blood Pressure Monitor cuff inflates again while measuring, it could be because the cuff is not fastened properly. Make sure to fasten the cuff again. Also, if your blood pressure is higher than the pressure the device has inflated, the device will automatically increase the pressure and start to inflate again. In this case, stay relaxed and wait for the measurement to complete.
