CD SECTION

Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessary
to reajust it.
Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.

TEST MODE

While holding down the "PLAY" button, move the FUNCTION/POWER switch to "CD".

Start

Note

1. When the CD LID switch is in the OFF position, (CD LID is open) the unit will be able to enter the test mode.

However, can use the "UP/CUE" and "DOWN/REVIEW" button only.

2. You can only move the pickup.
3. The LCD display should be the same as it is for normal CD operations.

Operation

The use of the "UP/CUE" button will move the pickup to the outermost position.
The use of the "DOWN/REVIEW" button will move the pickup to the innermost position.

After connecting of the 10k

Ω

resistor between IC802 27 pin and GND and holding down the "PLAY" button, move

the FUNCTION/POWER switch to "CD".

Start

Display

LCD MODE

1. Remove the front cabinet according to the disassembly method.
2. Short the TP of the Figure 11-1 to turn on the CD LID SW 810.
3. While holding down the "PLAY" button, move the FUNCTION/POWER switch to "CD".
4. Open the CD LID and press the PLAY button. The laser lights up for a few seconds. (At this time, the pickup lens moves up

and down and adjusts the focus to check if there is a disc or not.)
