🔍 Key Concepts

• EPIRB (Emergency Position-Indicating Radio Beacon) basic functions: radio signal, homing signal, and any built‑in visual aids • Difference between radio frequencies (121.5 MHz and 406 MHz) and visual signals • Typical search and rescue signaling equipment (lights, flares, sounds) and what each is used for

💭 Think About

• Which option describes something that can actually be seen by rescuers from a distance, especially at night? • Which of these choices are radio signals (invisible) versus optical/visual signals (light)? • On a real EPIRB, what additional feature helps a rescue helicopter or vessel physically spot the beacon once they are in the general area?

✅ Before You Answer

• Identify which choices are radio frequencies (not visible to the eye). • Identify if any option mentions a light source that could be seen by rescuers. • Ask yourself: during a night search at sea, which of these would help rescuers visually locate the casualty once they are close?
