1. Set the SHUTTLE switch in the HOLD position.
2. While keeping pressing the  Nx    button in the HOLD

position, press the  RESET  switch.

3. Then the characters “PREPARING …” is displayed

momentarily, and then the following indication is displayed
on screen.

1. While the machine is in the TEST mode, set the SHUTTLE

switch to the normal mode (i.e., in the center position)

2. When the  Nx  button is pressed, the following indication is

displayed on the screen.

3. Whenever the  SEARCH/MENU  button is pressed, the

indication toggles between the following two indications as
shown below.

m

4. When the  DISP/FUNC  button is pressed, the following

indication is displayed on the screen.

5. When the  VOL+  button is pressed, the following indication

is displayed on the screen.

6. When the  VOL–  button is pressed, the following indication

is displayed on the screen.

7. When the  REPEAT/SOUND  button is pressed, the following

indication is displayed on the screen.

8. Whenever the SHUTTLE switch is rotated in the direction of

>+  , the indication toggles between the following two
indications as shown below.

9. Whenever the SHUTTLE switch is rotated in the direction of

.–  , the indication toggles between the following two
indications as shown below.

1. While the machine is in the TEST mode, set the SHUTTLE

switch to the ALBUM position.

2. The entire screen shows the checkered pattern and the machine

enters the display check mode.

3. When the SHUTTLE switch is rotated in the direction of

>+  , all indicators are turned ON.

4. When the  SEARCH/MENU  button is pressed, amount of

brightness of all indications is reduced to the dim state.

* When the  DISP/FUNC   button is pressed in the dim state,

amount of brightness of all indicators returns to the full
brightness.

* When either button of  Nx  button or the VOL+  button

or the  VOL–  button is pressed in the dim state, amount
of brightness of all indicators returns to the full brightness
for 9 seconds and then returns back to the dim state.

5. When the SHUTTLE switch is rotated in the direction of the

.–  , all indicators are turned OFF.

6. When the SHUTTLE switch is set to the normal mode (i.e., in

the center position), the following indication displayed on the
screen and the machine enters the key check mode.

Press the  RESET  switch in any state to exit the test mode.
