ANC/Active Sound Control system check mode

ANC active sound control can be turned ON or OFF, and you can check the current status. The ANC/active sound control switches ON and OFF with every push of the No. 1 button. If "- -" appears on the display, use this check mode to check for loose wires or poor connections at the ANC/active sound control unit connector (16P).
