2-2-1-1 Cooling
The cooling requirement for the Vivid 7 / Vivid 7 PRO is 3500 BTU/hr. This figure does not include
cooling needed for lights, people, or other equipment in the room. Each person in the room places an
additional 300 BTU/hr. demand on the cooling system.
2-2-1-2 Lighting
Bright light is needed for system installation, updates and repairs. However, operator and patient
comfort may be optimized if the room light is subdued and indirect. 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.
CAUTION
If the unit is very cold or hot, do not turn on its power until it has had a chance to acclimate to
its operating environment.
