Environmental Requirements For Probes; Time And Manpower Requirements - GE Voluson E Series Service Manual

Site Preparation
EMI Rule
Be aware of Radio
Frequency sources.
Ground the system.
Assemble all screws, Radio
Frequency gaskets, covers
and cores.
Replace broken Radio
Frequency gaskets.
Do not place labels where
Radio Frequency gaskets
touch metal.
Use GE- specified harnesses
and peripherals.
Take care with cellular
phones.
Properly route peripheral
cables.

2.1.4 Environmental Requirements for Probes

Probes can be used in clinical environment.
Ensure that the probe face temperature does not exceed the normal operation temperature range.
Probes must be operated, stored, or transported within the parameters outlined below.
Temperature
Humidity
Pressure

2.1.5 Time and Manpower Requirements

Site preparation takes time. Begin site preparation checks as soon as possible. If possible, six weeks before
delivery, to allow enough time to make any changes.
Warning
Have two people available to deliver and unpack the Voluson E-Series ultrasound system.
Attempts to move the system considerable distances (or on an incline) by one person alone, could result in
personal injury and/or damage to the system.

Table 2-3 EMI prevention/abatement
Keep the system at least 5 meters (15 feet) away from other EMI sources. Special shielding may be
required to eliminate interference problems caused by high frequency, high powered radio or video
broadcast signals.
Poor grounding is the most likely reason a system will have noisy images. Check grounding of the
power cord and power outlet.
After you finish repairing or updating the system, assemble all covers and tighten all screws. Any
cable with an external connection requires a magnet wrap at each end. Install all covers. Loose or
missing covers or Radio Frequency gaskets allow radio frequencies to interfere with the ultrasound
signals.
If more than 20% or a pair of the fingers on an Radio Frequency gasket are broken, replace the
gasket. Do not turn ON the system until any loose metallic part is removed.
Never place a label where Radio Frequency gaskets meet the system. Otherwise, the gap created
will permit Radio Frequency leakage. In case a label has been found in such a position, move it to
another more suitable location.
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.
Cellular phones may transmit a 5 V/m signal; that could causes image artifacts.
Do not allow cables to lie across the top of the card rack 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.
