5、02Safety Instructions, Warnings, Notes, and Service Hints EN 3DVD580M 2.2. Safety Instructions, Warnings, Notes, and Service Hints2.1 Safety Instructions2.1.1 General SafetySafety regulations require that during a repair: Connect the unit to the mains via an isolation transformer.Replace safety comp

6、onents, indicated by the symbol g19, 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.Safety regulations require that after a repair, you must return the unit in its original condition.

7、 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 the electrical DC resistance between the mains plug and the secondary side:1. Unplug the mains cord, an

8、d connect a wire between the two pins of the mains plug.2. Set the mains switch to the on position (keep the mains cord unplugged!).3. Measure the resistance value between the mains plug and the front panel, controls, and chassis bottom. 4. Repair or correct unit when the resistance measurement is l

9、ess than 1 M. 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.2.1.2 Laser SafetyThis unit employs a laser. Only qualified service personnel may remove the cover, or attempt

10、to service this device (due to possible eye injury).Laser Device UnitType : Semiconductor laser GaAlAsWavelength : 650 nm (DVD): 780 nm (VCD/CD)Output Power : 20 mW (DVD+RW writing):0.8 mW (DVD reading): 0.3 mW (VCD/CD reading)Beam divergence : 60 degreeFigure 2-1 Note: Use of controls or adjustment

11、s or performance of procedure other than those specified herein, may result in hazardous radiation exposure. Avoid direct exposure to beam.2.2 Warnings2.2.1 GeneralAll ICs and many other semiconductors are susceptible to electrostatic discharges (ESD, g34). Careless handling during repair can reduce

12、 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 equipment: Complete kit ESD3 (small tablemat, wristband, connection box, extension cable a

13、nd earth cable) 4822 310 10671. Wristband tester 4822 344 13999.Be careful during measurements in the live voltage section. The primary side of the power supply (pos. 1005), including the heatsink, carries live mains voltage when you connect the player to the mains (even when the player is off!). It

14、 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 lightning stroke and a stripe-marked printing on the printed wiring board, indicate

15、the primary side of the power supply.Never replace modules, or components, while the unit is on.2.2.2 LaserThe use of optical instruments with this product, will increase eye hazard.Only qualified service personnel may remove the cover or attempt to service this device, due to possible eye injury.Re

16、pair handling should take place as much as possible with a disc loaded inside the player.Text below is placed inside the unit, on the laser cover shield:Figure 2-2 2.2.3 NotesDolbyManufactered under licence from Dolby Laboratories. “Dolby”, “Pro Logic” and the double-D symbol are trademarks of Dolby
