本体パネルキー、プロテクションなどを検出している端子の
A/D変換の値を、サブメニューで%表示します。信号処理は実
行前の状態を維持します。
K0のメニューにすると、全キーの値を検出するためキー操作
はできなくなりますが、本体のVOLUMEを回すことにより、
次のサブメニューに進めることができます。このとき2ク

9. AD DATA CHECK/FAN TEST
This menu is used to display the A/D conversion value of the
terminals which detect the panel keys of the main unit and
protection functions in % using the sub-menu. During signal
processing, the condition before execution is maintained.
When K0 menu is selected, keys become non-operable due
to detection of the values of all keys.
However, it is possible to advance to the next sub-menu by
turning the VOLUME of the main unit. When using this func-
tion, note that turning the VOLUME more than 2 clicks will
cause the volume value to change.
* The figures in the diagram are given as reference only.
PS/PS2 (protection detection)
PS: Value of power supply voltage protection other than
DVD (Normal value: 49 to 60)
P2: Value of power supply voltage protection related to
DVD (Normal value: 46 to 70)
If PS or P2 is out of the normal value range, the protection
function works to turn off the power after 1 second.
K0 (Panel key of main unit)
A/D of the key fails to function properly when the standard
value is deviated. In this case, check the constant of partial
pressure resistor, solder condition, etc. Refer to table 1.

K0:100%
DVD以外の電源電圧プロテクションの値
（正常値49 ∼60 ）
DVD関連の電源電圧プロテクションの値
（正常値46 ∼70 ）
PS、P2は正常値を外れるとプロテクションが働き、電源オフ
されます。
キーのA/Dは基準値から外れると、正常な動きをしません。
Table 1 をご覧になり、各キーの分圧抵抗の定数、ハンダ不良
等の確認をしてください。
