General safety Safety regulations require that du

5、ring a repair: . Connect the unit to the mains via an isolation transformer. . Replace safety components indicated by the symbol , only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard. Safe

6、ty regulations require that after a repair, you must return the unit in its original condition. Pay, in particular, attention to the following points: . Route the wires/cables correctly, and fix them with the mounted cable clamps. . Check the insulation of the mains lead for external damage. . Check

7、 the electrical DC resistance between the mains plug and the secondary side: 1) Unplug the mains cord, and connect a wire between the two pins of the mains plug. 2) Set the mains switch the “on” position (keep the mains cord unplug). 3) Measure the resistance value between the mains plug and the fro

8、nt panel, controls, and chassis bottom. 4) Repair or correct unit when the resistance measurement is less than 1M . 5) Verify this, before you return the unit to the customer/user (ref. UL-standard no. 1492). 6) Switch the unit “off”, and remove the wire between the two pins of the mains plug. 2.Las

11、eptible to electrostatic discharges (ESD). Careless handing during repair can reduce life drastically. Make sure that, during repair, you are at the same potential as the mass of the set by a wristband with resistance. Keep components and tools at this same potential. Available ESD protection equipm

Be careful during measurements in the live voltage section. The primary side of the power supply , including the heat sink, carries live mains

13、voltage when you connect the player to the mains (even when the player is “off”!). It is possible to touch copper tracks and/or components in this unshielded primary area, when you service the player. Service personnel must take precautions to prevent touching this area or components in this area. A

Laser . The use of optical instruments with this product, will increase eye hazard. . Only qualified service

15、personnel may remove the cover or attempt to service this device, due to possible eye injury. . Repair handing should take place as much as possible with a disc loaded inside the player. .
