2.Error Signal Check And Solutions
2.1.Error message『LE1』：The voltage is too lo during exercising, please check the input
AC po er source, AC po er source voltage shall bet een 110 / 220 V ± 10%.
2.2.Error message『OC』：The inverter output current overload(over 17.6A), replace inverter
if after reset po er then start again still sho 『OC』. Replace the running belt or
deck if al ays happen hile running.
2.3.Error message『OE』：The operation voltage too high, maybe happen at high incline level
and heavy load exercising, contact manufacture for solution.
