During the installation and start–up of the system you must take continuous temperature checks to make sure the
environment meets specifications listed in Section 3 of the Preinstallation manual (P9018AR). Excessive temperature,
coupled with reduced air flow from clogged filters, may overstress components and cause failures.
Filters
Check
and clean all electronic equipment dust filters. GE recommends initially doing this on a weekly basis, because

Required Phantoms
Use the following phantoms (furnished with each system) during image performance.
Make sure they are clean and contrast–free.
arm–Up the system at least 2 hours before the data collection.
All image performance scans must use calibration scans that are less than 8 hours old.
