EMI Prevention/abatement
EMI Rule
After you finish repairing or updating the system, replace all covers and tighten all screws.
Any cable with an external connection requires a magnet wrap at each end. Install the
shield over the front of card cage. Loose or missing covers or RF gaskets allow radio
frequencies to interface with the ultrasound signals.
If more than 20% or a pair of fingers on the RF gaskets are broken, replace the gaskets.
Do not turn on the unit until any loose metallic part is removed.
Never place a label where RF gaskets meet the unit. Otherwise, the gap created will permit
RF leakage. Or, if a label has been found in such a position, move the label.
The interconnect cables are grounded and require ferrite beads and other shielding. Also,
cable length, material, and routing are all important; do not change from what is specified.
Do not allow cables to lie across the top of the card cage or hang out of the peripheral bays.
Loop the excess length for peripheral cables inside the peripheral bays. Attach the monitor
cables to the frame.
