My Omron unit keeps coming up with EE. How do I correct this?

is it a 780 or a 731? found manual for 780; http://omronhealthcare.com/wp-content/uploads/hem-780-instruction-manual.pdf nothing on 731. Try removing the battery for 10 min to reset all. May be time to replace.

Check your user manual, there should be a section on error codes. Most often E or EE errors are leaking cuff or improper use.

You can use a multi voltage mains adapter for your Omron. These are available at electronic stores ot on the Internet. Make sure it is a DC adapter and switch to 6 volts also make sure the power connector is set correctly to the polarity of the Omron power socket.

Hi. One of the most common error symbol that appears on this display panel is a EE with a down arrow and two numerals. The reason for the EE Error Indicator is usually caused because the cuff has been wrapped too loose. The cuff was under-inflated during the measurement. This error will also display if the cuff is worn and needs to be replaced. The EE symbol with a down arrow indicates the cuff is over-inflated. In most instances the cuff has been wrapped too tight or you are using the incorrect cuff size. Turn the monitor off. Read the instructions to correctly apply the cuff. Wait five to ten minutes then take another measurement. This should correct the issue.

'EE' means cuff is underinflating. Re wrap cuff with varying amounts of pressure and restart [wait 2 minutes between readings].

EE=Cuff under-inflated=not inflated enough. While cuff is inflated, keep pressing START button until pressure reaches 15-20 mmHg higher than the pressure when it stops and displays EE. Make sure at least 5 min allowed between readings.

That either means you are moving, or you are inflating the cuff to soon after turning it on. Either of these is what mine means when I use it.
