Console Requirements
2-2-1 Unit Environmental Requirements
CAUTION: If the system has been in storage or has been transported, please see the acclimation
requirements before powering
ON
and/or using the system. Refer to the Installation Warnings section
on page 3-2.
2-2-2 Cooling Requirements
The cooling requirement for the Vivid 3N Pro/Expert ultrasound unit environment is
3500 BTU/hr. This figure does not include the cooling required for lights, people, or other equipment in
the room.
Note: Each person in the room places an additional 300 BTU/hr demand on the environmental cooling.
2-2-3 Lighting Requirements
For system installation, updates and repairs, bright lighting is required. However, operator and patient
comfort may be optimized if the room lighting is subdued and indirect when a scan is being performed.
Therefore, a combination lighting system (dim/bright) is recommended. Keep in mind that lighting
controls and dimmers can be a source of EMI which could degrade image quality. These controls should
be selected to minimize possible interference.
2-2-4 Time and Manpower Requirements
Site preparation takes time. Begin pre-installation checks as soon as possible to allow sufficient time to
make any required changes. If possible, begin these checks as many as six weeks before system
delivery.
CAUTION: At least two people must be available to deliver and unpack the Vivid 3N Pro/Expert
ultrasound unit. Attempts to move the unit considerable distances (or on an incline) by one person
alone, could result in personal injury, and/or damage to the system.
