Cat II EPIRB features:

Cat II EPIRB features:

• A. 406/121.5 MHz; Manually activated
• B. 406/121.5 MHz; Float-free, automatically activated
• C. 121.5/243 MHz; Float-Fix
• D. 406/243 MHz; Float-free, manually activated

Answer: (A)

Cat II EPIRBs are manually activated devices. They transmit on 406 MHz to alert the satellite system and also include a 121.5 MHz beacon for SAR homing once the distress signal is received. They are not float-free or automatically activated when in water; those features belong to the Cat I category. So the combination of 406/121.5 MHz with manual activation correctly describes Cat II EPIRBs.
