Investigated R/S box "RS03" in UITF for "safe light not visible" found the safe light bulbs/LED's are functioning but "dim". While investigating one of the Bulbs/sockets failed. Need to replace bulbs and some of the bulb sockets. Will schedule the repairs based on the UITF schedule (need access to cave for repair).

FSD window set point for 15 deg dipole (MDR1I02 Low Noise Supply) for 140 kV Gun operation is updated.

Crew chief changed the MDR1I02 setpoint from -2.6 A to -2.08 A.

Max Bruker provided the new set point for 140 kVas -2.08 A. High and low limits are set as 20% of the nominal per Joe Grames instruction.

Per Scott Higgins request he is been notified about this change.
