5.2 Factory Default Settings

Below is a list of factory-presets. To reinitialize the MPS to factory presets at any time, hold the Esc key for

about 15 seconds.

NOTE: If the MPS is part of a superconducting magnet system, the system supplier may change some of the

parameters below to optimize MPS operation to the superconducting magnet it works with.
