  • Page 4 The protection circuitry may have operated if either of the following conditions are noticed: - No sound is heard when the power is turned on. - Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are "shorted", or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
  • Page 5 4. Handling Precautions For Traverse Deck (CD/MD) The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). Handling of CD traverse deck (optical pickup) 1.
  • Page 6 Handling of MD Unit (optical pickup) 1. Do not subject the MD unit (optical pickup) to static electricity as it is extramely sensitive to electrical shock. 2. The short land between the No.25 (LD-GND) and No. 24 (LD) pins on the flexible board is shorted with a solder builder up to prevent damage to the laser diode.

  • Page 7: Precaution Of Laser Diode

    Caution when Replacing the Optical Pickup : The traverse has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to remove the solder from the short point before making connections. 5. Precaution of Laser Diode Caution : This product utilizes a laser diode with the unit turned "ON", invisible laser radiation is emitted from the pick up lens.
