There are several possibilities when a scale LED display doesn’t work properly.
(1) LED no display: Check the batteries. Check if the batteries are installed properly or replace new batteries if necessary.
(2) LED displays “Lo”: “Lo” refers to Low Battery. Check if the batteries are installed properly or replace new batteries if necessary.
(3) LED displays “EEr”: “EEr” refers to Error. The scale sensor may be overloaded or even damaged. Don’t use the scale if your weight is over the range. This scale only works for less than 396 lbs (180 kg).
