EPIRBs are tested ___ at a minimum and must be able to transmit for at least ___.

Regular checks keep an EPIRB ready for action. It must be tested at least monthly to verify the battery, antenna, and internal circuitry are functioning properly. The beacon also needs enough endurance to transmit for at least 48 hours if activated, so rescue crews have a lasting signal to locate you even if response times are longer. In practice, you perform a test in accordance with the manual, which confirms operation without initiating a full emergency transmission. The 406 MHz distress signal is picked up by satellites and sent to rescuers, while the 121.5 MHz signal serves as a homing aid once responders are nearby.
