If power outage occurs

When the power is applied again after the unit has stopped due to power outage, the unit will

automatically return to the status immediately before the power outage and resumes operation.

Turn the ELB off if you do not want to resume operation by automatic recovery.

◆If the symptom does not match any of the above, immediately turn the ELB on the main unit off,

pull out the power cord from the power supply and contact your dealer or one of our sales

offices.
