Safety Information, General Notes2.1 Description of the Production Number on the type plateThe type plate of the set contains a production number that consists of the following:2.1.1 The Site Code (Production center) The site code co

20、nsists of 2 letters and relates to the factory assembling and/or equipping the products. The site code letters valid for Consumer Electronics are stated in UAT-0477. The code is used to trace the production site of the model number, e.g. VN.SzekesfehervarKB.HasseltKT.SBI Electronics Shenzhen2.1.2 BO

21、M CodeThe BOM code is used to link the model to the actual Bill Of Material used for assembly during set production. One set model can be made up of different standard designs / modules. This depends on the material availability in the production or the development progress of the successor modules.

22、 Different modules may be used during the same production period or changed back and forth from one week to the other.BOM version 1 gets BOM code 1, BOM version 2 gets BOM code 2, etc. Allowed codes are 1-9, A-Z.2.1.3 Service Version Change CodeThe service version change code, which has to be recogn

23、izable for service and production departments, is used to indicate a production change that is considered as a major change affecting the “serviceability” of the product. A major change is occurring when a safety component is changed or when the servicer needs additional information to repair the se

24、t. E.g. when the software is changed or when an IC and its peripheral circuit are changed. Allowed characters are (A-Z, 0-9) to be used in the following sequence: A-Z followed by 0-9.2.1.4 Production year/week codeIndicates the actual week of set assembly. Made up of the last two digits of year plus

25、 production week.2.1.5 Serial numberThe six digit serial numbers.2.2 Safety Instructions2.2.1 General SafetySafety regulations require that during a repair:Connect the unit to the mains via an isolation transformer.Replace safety components, indicated by the symbol , only by components identical to

26、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. Pay, in particular, attention to the following points:Route the wire

27、s/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, and connect a wire between the two pins of the mains plug.2. Set the ma

28、ins 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 less than 1 M. 5. Verify this, before you return the unit to the custo

29、mer/user (ref. UL-standard no. 1492).6. Switch the unit off, and remove the wire between the two pins of the mains plug.2.2.2 Laser SafetyThis unit employs a laser. Only qualified service personnel may remove the cover, or attempt to service this device (due to possible eye injury).Laser Device Unit

31、 result in hazardous radiation exposure. Avoid direct exposure to beam.2.3 Warnings2.3.1 GeneralAll ICs and many other semiconductors are susceptible to electrostatic discharges (ESD, ). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are at the same p

32、otential as the mass of the set by a wristband with resistance. Keep components and tools at this same potential.

33、Notes EN 7HDRW720/0x, DVDR725H/0x 2. 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!

34、). 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 lightning stroke and a stripe-marked printing on the printed wiring board, indi

35、cate the primary side of the power supply.Never replace modules, or components, while the unit is on.2.3.2 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 inju
