Why does my ReliOn BP300 Blood Pressure Monitor show high or low values?
Blood pressure constantly varies based on many factors such as stress, time of day, and how you wrap the cuff. Please review the “Before Taking a Measurement” and “Taking a Measurement” sections for guidance.
Why my ReliOn BP300 Blood Pressure Monitor does not turn on?
If your ReliOn Blood Pressure Monitor does not turn on when you push the START/STOP button, the batteries may be dead. Replace them with four new "AA" alkaline batteries. Also, check that the battery polarities are correct when you insert them.
What to do if my ReliOn Blood Pressure Monitor displays the EE error?
If your ReliOn Blood Pressure Monitor displays the EE error symbol or shows a blood pressure value that seems too low or too high, it might be due to incorrect cuff placement. Make sure you wrap the cuff properly so that it's positioned correctly. Also, avoid talking or moving during the measurement; keep your arm steady and try measuring again. Shaking your arm with the cuff on can also cause this error.
What to do if my ReliOn Blood Pressure Monitor displays the E1 error?
If your ReliOn Blood Pressure Monitor displays the E1 error symbol, it indicates an air circuit abnormality. This could be because the cuff tube isn't properly plugged into the monitor. Check the cuff connection and then measure again.
What to do if my ReliOn Blood Pressure Monitor displays the E2 error?
If your ReliOn Blood Pressure Monitor displays the E2 error symbol, it means the inflation pressure exceeded 300 mmHg. Switch the unit off and then measure again.
What to do if my ReliOn BP300 displays the EP error?
If your ReliOn Blood Pressure Monitor displays the EP error symbol, it indicates a system error. Try measuring again.
What to do if my ReliOn Blood Pressure Monitor has no power?
If your ReliOn Blood Pressure Monitor has no power and no display appears, replace all four batteries with new ones. Also, check that the battery polarities are correctly aligned during installation.
