WARNING
Connecting a DUS 60 system to the wrong voltage level may destroy the system.
3.2. Unpacking
Carefully remove foam packing material and plastic bag from the ultrasound unit.
3.3. Preparing for Installation
Compare the items received from the customer to those listed on the delivery order. Report any
items that are missing, back ordered or damaged.
EMI Limitations
Ultrasound machines are susceptible to Electromagnetic Interference (EMI) from radio
frequencies, magnetic fields, and transients in the air of wiring. Ultrasound machines also
generate EMI. The DUS 60 complies with limits as stated on the EMC label. However, there is no
guarantee that interference will not occur in a particular installation.
Possible EMI sources should be identified before the unit is installed.
EMI Rule Prevention Tips
Be aware of RF sources Keep the unit at least 5 meters or 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.
Ground the unit Poor grounding is the most likely reason why a unit will have noisy images.
Check grounding of the power cord and power outlet.
Replace all screws, RF
gaskets, covers, cores
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. Losing
covers or RF gaskets will cause radio frequency interference with the
ultrasound signals.
Do not place labels Never place a label where RF gaskets meet the unit. Otherwise, the gap
