MP115 Digital Media Player Operation Environment Preliminary

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

Service Considerations

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.

Preventing Electrostatic Damage

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.

Packaging and Transporting Precautions

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.

Workstation Precautions

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.
