The led is ON by default. When using CNF-05 function (animal scale mode) or FNC-07 function (HOLD function setting) it
works as a hold led. In the other hand when using the multi-range mode, this led is used to indicate the range situation
where we are.
CFN-05 (animal scale mode) and FNC-07(HOLD function setting) functions can not work at the same time.
