3. SW/VR check

Depressing any button following the 7-segment LED display

pattern causes the switch name to appear on the LCD screen.

Depress the button following the display and check that the

display on the LCD screen changes accordingly.

Upon completion of checking all buttons, the VR names will

appear on the LCD screen.

While "0" is displayed on the 7-segment screen, operate each

VR to the left.

While "1" is displayed, operate each one to the right.

Upon completion of check, moving to the next VR takes place

automatically.

When the last VR has been operated and the check is

successfully concluded, moving to the next step takes place

automatically.

If something is found to be wrong during this process, you

cannot go to the next SW/VR check or step.

4. DSP check

The following check will be made automatically.

4-1. Initialization test

When the result is 'NG', "ERROR 1" will appear on the LCD

screen and you will not be able to go to the next step.

If the result is 'OK', go to the next step without displaying

anything.

4-2. Internal RAM read/write test

When the result is 'NG', "ERROR 2" will appear on the LCD

screen and you will not be able to go to the next step.

If the result is 'OK', go to the next step without displaying

anything.

4-3. External RAM read/write test

When the result is 'NG', "ERROR 3" will appear on the LCD

screen and you will not be able to go to the next step.

If the result is 'OK', go to the next step without displaying

anything.

3. SW/VR チェック

7SEG, LED 表示パターンに続いてどれかキーを押すと、

LCD にスイッチ名が表示されます。

表示に従ってキーを押し、これに対応して LCD の表示が

変化することを確認して下さい。

全てのキーの確認が終わると、LCD には VR の名称が表

示されます。

7SEG に "0" が表示されている時は左に、1 が表示されて

いる時は右に、それぞれの VR を操作してください。

確認が終わると自動的に次の VR へ移動します。

最後の VR が操作され、チェックが正常に終了しますと、

自動的に次のステップへ進みます。

この時、異常があれば次の SW/VR チェック及び次のス

テップに進む事が出来ません。

4. DSP チェック

以下の検査を自動的に処理します。

4-1. 初期化のテスト

結果が 'NG' の場合、LCD に "ERROR 1" が表示され、次
