All three status boxes on the GSU Page (config mode) must indicate a positive state (green check marks)
before performing any calibration procedures (Section 8). The GMU 44 and GSU 73 units must be
communicating with the GDU 37X, and the GPS antenna must have clear view of the sky to produce
positive status indications.
