Trouble Mode 1 The system will not start properly.

• The check code display appears on the remote controller.

• The LED of the Lossnay circuit board is blinking.

Check with the check code list (table 2).

Trouble Mode 3 The remote controller does not operate or operates irregularly.

The Lossnay does not operate or operates irregularly.

Trouble Mode 4

Check with the remote controller checklist (table 3).

Check with the Lossnay checklist (table 4).

Precautions when diagnosing malfunctions● When removing a transistor or printed circuit board, make sure the breaker is thrown.● When removing the circuit board, always hold it at both ends and remove carefully so as not to apply force to the surface

mounted parts.● When removing the circuit board, be careful of the metal edges on the board.● When removing or inserting the connectors for the circuit board, hold the entire housing section. Never pull on the lead

wires.● When servicing, be sure to recreate the malfunction 2 to 3 times before starting repairs.● If a malfunction of the printed circuit board is suspected, check for disconnected wires in the print pattern, burnt parts or dis-

coloration.● If the printed circuit board is replaced, make sure that the switch settings on the new board are the same as the old board.
