This section provides essential information for proper and safe installation and replacement service. 

 

  The following sections include some of the considerations that you should keep in mind during disassembly 

  and assembly procedures. 

  Note: As you remove each subassembly from the Digital Media Player, place the subassembly (and 

  all accompanying screws) away from the work area to prevent damage. 

  • Plastic Parts 

 

 

   

 

Using excessive force during disassembly and reassembly can damage plastic parts. Use care when 

 

 

   

 

handling the plastic parts. Apply pressure only at the points designated in the

 

maintenance instructions. 

    • Cables and Connectors 

 

 

   

 

Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or 

 

 

   

 

seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all 

 

 

   

 

cases, avoid bending, twisting, or tearing cables. Ensure that cables are routed in such a way that they 

 

 

   

 

cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; 

 

 

   

 

these cables tear easily. 

  Caution: When servicing the Digital Media Player, ensure that cables are placed in their proper 

  locations during the reassembly process. Improper cable placement can damage the Digital Media 

  Player. 

 

  Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure 

  determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, 

  but in many cases the discharge contains enough power to alter device parameters or melt silicon junctions. 

  A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices 

  or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. 

  An electronic device exposed to electrostatic discharge may not be affected at all and can work perfectly 

  throughout a normal cycle. Or the device may function normally for a while, and then degrade in the 

  internal layers, reducing its life expectancy. 

 

  Use the following grounding precautions when packaging and transporting equipment: 

    • To avoid hand contact, transport products in static-safe containers, such as tubes, bags, or boxes. 

    • Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or 

 

 

   

 

packaging. 

    • Keep electrostatic-sensitive parts in their containers until the parts arrive at static-free workstations. 

    • Place items on a grounded surface before removing items from their containers. 

    • Always be properly grounded when touching a sensitive component or assembly. 

    • Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive 

 

 

   

 

foam. 

    • Use transporters and conveyors made of antistatic belts and roller bushings. Ensure that mechanized 

 

 

   

 

equipment used for moving materials is wired to ground and that proper materials are selected to avoid 

 

 

   

 

static charging. When grounding is not possible, use an ionizer to dissipate electric charges. 

 

  Use the following grounding precautions at workstations: 

    • Cover the workstation with approved static-dissipative material. 

    • Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and 

 

 

   

 

equipment. 

    • Use conductive field service tools, such as cutters, screwdrivers, and vacuums. 

    • When using fixtures that must directly contact dissipative surfaces, only use fixtures made of static-safe 

 

 

   

 

materials. 

    • Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and 

 

 

   

 

Styrofoam. 

    • Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle 

 

 

   

 

these items only at static-free workstations. 

    • Avoid contact with pins, leads, or circuitry.
