When there is a history of protection function:
The FL display appears as shown below depending on the
type of the protection function.
プロテクション履歴がある場合:
スピーカーをショートさせた時などが原因で、
プロテクションが働いたことを示します。
アンプの故障でスピーカーに直流電圧が掛
かるなどが原因で、プロテクションが働い
たことを示します。異常状態のままパワー
オンすると、約4秒後にプロテクションが掛
かり、電源が切れます。
電源電圧による原因で、プロテクションが
働いたことを示します。異常状態のままパ
ワーオンすると、約1.5秒後にプロテクショ
ンが掛かり、電源が切れます。
温度制限を越えた原因で、プロテクション
が働いたことを示します。異常状態のまま
パワーオンすると、約2秒後にプロテクショ
ンが掛かり、電源が切れます。
The protection function worked due to exces-
sive current through the amplifier. Causes
could be a short at the speaker terminal or a
defect in the amplifier. The protection func-
tion activates immediately to turn off the
power, with no history display at turn-on, if
the amplifier is defective.
The protection function worked due to a DC
voltage appearing at the speaker terminal.
A cause could be a defect in the amplifier. If
the power is turned on with the abnormality
unsolved, the protection function works in
about 4 seconds to turn off the power.
The protection function worked due to a de-
fect or overload in the power supply. If the
power is turned on with the abnormality un-
solved, the protection function works in about
1.5 seconds to turn off the power.
The protection function worked due to the
temperature limit being exceeded. Causes
could be poor ventillation or a defect related
to the thermal sensor. If the power is turned
on with the abnormality unsolved, the pro-
tection function works in about 2 seconds to
turn off the power.

● History of protection function
When the protection function has worked, its history is stored
in memory with a backup. Even if no abnormality is noted while
servicing the unit, an abnormality which has occurred previ-
ously can be defined as long as the backup data has been
stored.
The history of the protection function is cleared when DIAG is
cancelled by selecting PRESET RESERVED (Memory initial-
ized) of DIAG menu No.18 or when the backup data is erased.
●プロテクションの履歴
プロテクションが働いた場合、履歴をバックアップして記憶していま
す。サービスのときに異常が認められなくても、バックアップが残って
いれば、お客様のところで起きた異常を区別できます。
ダイアグメニュー No.18 で PRESETRESERVED（メモリーの初期化）
を選んでダイアグを解除した場合、またはバックアップが消えた場合
に、プロテクションの履歴はクリアされます。
