Precautions

On safety

Should any solid objects or liquid fall into the CD player, unplug it and have it checked by qualified personnel before operating it any further. Do not put any foreign objects in the DC IN 4.5 V (external power input) jack.

On headphones/earphones

Road safety Do not use headphones/earphones while driving, cycling, or operating any motorized vehicle. It may create a traffic hazard and is illegal in some areas. It can also be potentially dangerous to play your headsets at high volume while walking, especially at pedestrian crossings. You should exercise extreme caution or discontinue use in potentially hazardous situations. Preventing hearing damage Avoid using headphones/earphones at high volume. Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce volume or discontinue use. Consideration for others Keep the volume at a moderate level. This will allow you to hear outside sounds and to be considerate to the people around you.

Laser Diode Checking Methods During normal operation of the equipment, emission of the laser diode is prohibited unless the upper panel is closed while turning ON the S801 (push switch type). The following checking method for the laser diode are operable. Method : Emission of the laser diode is visually checked. 1. Open the upper lid. 2. Push the S801 as shown in Fig. 1. 3. Check the object lens for confirming normal emission of the laser diode. If not emitting, there is a trouble in the automatic power control circuit or the optical pick-up. During normal operation, the laser diode is turned ON about 2.5 seconds for focus searching.

Procedure: 1. Connect the oscilloscope to the test points TP629 (RF) and TP635 (GND) on the MAIN board. 2. Set a disc. (YEDS-18) 3. Press the u button. 4. Check the oscilloscope waveform is as shown below. A good eye pattern means that the diamond shape () in the center of the waveform can be clearly distinguished.
RF Signal reference Waveform (Eye Pattern)
VOLT/DIV : 100 mV (With the 10 : 1 probe in use) TIME/DIV : 500ns
RF level 0.45 to 0.65 Vp-p (D-E777/EJ725) 0.38 to 0.6 Vp-p (D-EJ721)
To watch the eye pattern, set the oscilloscope to AC range and increase the vertical sensitivity of the oscilloscope for easy watching.
5. Stop revolving of the disc motor by pressing the x button.
