Calibration and system settings require restoration after initialization

Multiple adjustment settings and calibrations need to be manually configured after system initialization or data restore

Ranked causes

1. System initialization or EPROM reset performed (DIPSW 2-8/3-1 ON) (common)

First check

Verify FVR calibration values restored

Test point: FVR settings in equipment
Expected: Original recorded FVR values

Collimator blades coming loose or falling off high voltage

Collimator blades have become loose and in some cases fallen off the mobile X-ray system

Ranked causes

1. Small washer inadequate for securing collimator blade screws (common)

First check

Inspect collimator blade attachment for loose or missing washers

Test point: Collimator blade screw fasteners
Expected: Washers present and secure
