What should be done to set screws while prepping the Proclaim IPG?

Loosening the screws in quarter-turn increments is the correct approach when prepping the Proclaim IPG because it allows for controlled adjustments without risking over-loosening. This method helps ensure that the screws remain secure enough to maintain the device's integrity while also allowing for necessary adjustments during the setup process. By loosening in smaller increments, you can more accurately gauge the resistance and ensure that you do not compromise the components or the overall configuration of the device. This gradual approach minimizes the risk of the screws becoming too loose or disengaging entirely, which could lead to operational issues during the use of the device.
