Applies to

Personnel
1 technician · Intermediate — cleaning the projector lenses and confirming the internal projector's fixing screws is basic hand work, but the internal/external/median alignment sequence that follows requires taping solder to precise reference lines on a water phantom, reading a scanogram to confirm placement, taping a graduated-line paper target and driving the couch top a specified distance, and iteratively re-checking each projector's light-beam pattern until no misalignment remains; no torque value, electrical isolation, or power-down is called out in source for this item.
