Cables and Connectors
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Most cables used throughout the unit are flex cables. These cables must
be handled with extreme care to avoid damage. Apply only the tension
required to seat or unseat the cables during insertion or removal from the
connector. Handle cables by the connector or pull tabs whenever possible.
In all cases, avoid bending, twisting, or tearing the cables, and ensure
that cables are placed in such a way that they cannot be caught or snagged
by parts being removed or replaced.
