When out of order
D-CONTOUR
switch
FAIL: SW D-CNTR-FOH *[voltage] *[value]
FAIL: SW D-CNTR-OFF *[voltage] *[value]
FAIL: SW D-CNTR-MONI *[voltage] *[value]
HPF switch FAIL: SW HPF-120HZ *[voltage] *[value]

トラブルシューティング
失敗した場合、次の部品及び結線を確認します。
CPU(PCBDSP:IC504-60pin)→
D-CONTOUR スイッチ
CPU(PCBDSP:IC504-59pin)→ HPF スイッチ
If status received from fi rmware is not the one intended,
whether or not to performagain the test that status of
switch is the same is confirmed. The test is performed
again with “Retry” button, and not performed again with
“Cancel” button.
ファームウェアから受信した状態が意図した状態で
ない場合は、同一スイッチ状態のテストを再度実行
するか確認します。「Retry」ボタンで再テストを行
い、「Cancel」ボタンで再テストを行いません。
