Replace/recharge the battery within 3 days when the scale displays "Lo".
EEr indicates the scale sensor may have been overloaded or an internal programming error.
The scale can support a maximum weight of 396 pounds. If EEr is not caused by excessive weight, please restart the scale by taking out the batteries for 5 seconds (and putting them back in) or pressing the reset button for 5 seconds.
