Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.
(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than
the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.
(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in
hazardous radiation exposure.

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 10kΩ 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.)
