How to fix SENDO Advance when nothing appears on the display?
If nothing appears on the display of your SENDO Blood Pressure Monitor, even when it's turned on, it could be due to drained batteries or incorrect battery terminal positioning. Try replacing all batteries with new ones. If that doesn't work, reinstall the batteries, making sure the negative and positive terminals match the indications on the battery compartment.
Why SENDO Blood Pressure Monitor readings are too high or too low?
Inaccurate readings on your SENDO Blood Pressure Monitor can occur if the cuff isn't fastened correctly, if you moved your arm or body during the measurement, or if the cuff position isn't correct. To resolve this, ensure the cuff is fastened correctly, remain still and quiet during the measurement, and sit comfortably with your hand raised so that the cuff is at the same level as your heart.
