Page 5: Laser Beam Safety Precautions
LASER BEAM SAFETY PRECAUTIONS This DVD player uses a pickup that emits a laser beam. Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin. The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 30cm away from the pickup lens when the diode is turned on.
Page 6: Important Safeguards And Precautions
IMPORTANT SAFEGUARDS AND PRECAUTIONS 1. IMPORTANT SERVICE NOTES BEFORE RETURNING THE DVD VIDEO PLAYER Reverse the AC plug on the set and repeat AC voltage measurements for each exposed part. Any reading of Before returning the DVD video player to the user, 1.4V rms (this corresponds to 0.7mA rms AC.) or more is excessive and indicates a potential shock hazard perform the following safety checks.

Page 107 1. Tape Interchangeability Alignment Note: To do these alignment procedures, make sure that the Tracking Control Circuit is set to the preset position every time a tape is loaded or unloaded. (Refer to page 2-3-4, procedure 1-C, step 2.) Equipment required: Dual Trace Oscilloscope VHS Test Tape (FL6NS8) (Refer to "SERVICE FIXTURE AND TOOLS"...
Page 108 1-A. Preliminary/Final Checking and 3. Check to see that the tape runs without creasing at Take-up Guide Post [4] or without snaking between Alignment of Tape Path Guide Roller [3] and ACE Head. (Fig. M3 and M5) Purpose: 4. If creasing or snaking is apparent, adjust the Tilt Adj. Screw of the ACE Head.
Page 109 5. To shift the CTL waveform, press CH UP or CH 4. If the envelope is as shown in Fig. M8, adjust the DOWN button on the remote control unit. Then make height of Guide Roller [3] (Refer to Fig. M3) so that the sure that the maximum output position of PB FM waveform looks like the one shown in Fig.
Page 110 1-D. Azimuth Alignment of Audio/ Control/ Erase Head Purpose: To correct the Azimuth alignment so that the Audio/ REV Post [5] Control/Erase Head meets tape tracks properly. Symptom of Misalignment: If the position of the Audio/Control/Erase Head is not properly aligned, the Audio S/N Ratio or Frequency Response will be poor.
