2-2-1-1 Cooling
The cooling requirement for the LOGIQ™ 7 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 diameters can be a source
of EMI which could degrade image quality. These controls should be selected to minimize possible
interface.
