  • Page 3 DRX-730/NX-E700 WARNING: Laser Safety This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during servicing of the unit. 1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm/1 feet away from the laser pick-up unit at all times.
  • Page 4 DRX-730/NX-E700 U, C models T, K, A, G, F, L, V models Warning for power supply The primary side of the power supply carries live mains voltage when the player is connected to the mains even when the player is switched off ! This primary area is not shielded so it is possible to accidentally touch copper tracks and/or components when servicing the player.

  • Page 5: Prevention Of Electrostatic Discharge

    DRX-730/NX-E700 ■ PREVENTION OF ELECTROSTATIC DISCHARGE Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge (ESD).
