Question 1740 Deck General

The correct answer is C) month. According to the regulations for Emergency Position Indicating Radio Beacons (EPIRBs) on Offshore Supply Vessels (OSVs), each EPIRB is required to be tested using the integrated test circuit and output indicator every month. This ensures the EPIRB is functioning properly and ready to be activated in the event of an emergency. The other options are incorrect because testing the EPIRB weekly (A) or every two weeks (B) would be too frequent, while testing it every two months (D) would be too infrequent to properly monitor the EPIRB's readiness.
