Faulty Operation Status Indication

A faulty operation status is indicated by the LED 1s Ml and M2 in the following conditions.

a) Ml and M2 flicker simultaneously. b) Ml lights up. c) M2 lights up.

LED's other than Ml and M2 light up corresponding to the failure conditions occurred to indicate them.

In any case, operations of the VAC drive unit become impossible.

Indication method of the failure contents differs depending on the ROM version. For ROM version, refer to Appendix 2.
