Page 2: Safety Information
Transistors Q101 in PCB drive the laser diodes. When Q101 is shorted between their terminals, the laser diodes will radiate beam. If the top cover is removed with no disc loaded while such short-circuit is continued, the naked eyes may be exposed to the laser beam. DEH-4000UB/XS/EW5... - Page 3 CAUTION Danger of explosion if battery is incorrectly replaced. Replaced only with the same or equivalent type recommended by the manufacture. Discord used batteries according to the manufacture's instructions. DEH-4000UB/XS/EW5...

The frequency of the clock signal is 468 750 Hz that is one 32th of the fundamental frequency. The clock signal should be 468 750 Hz (-10 Hz, +15 Hz) If the clock signal out of the range, the X’tal (X601) should be replaced with new one. DEH-4000UB/XS/EW5... -
Page 36: Checking The Grating After Changing The Pickup Unit
Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the average angle. Hint Reloading the disc changes the clamp position and may decrease the "wobble".
