Mars is so far away in fact that it takes radio signals quite a long time to get from the spacecraft back to Earth. During Curiosity EDL, this delay will be 13 minutes, 48 seconds, about mid-way between the minimum delay of around 4 minutes and the maximum of around 24 minutes.
The average notification time to Search and Rescue with this type of PLB is 45 minutes in the continental U.S. If you are using a PLB with a GPS interface, the 406 MHz signal will guide rescuers to an area less than 100 meters from your position. At the same time, SAR will be monitoring with a tracking device to home in on the 121.5 MHz frequency put out by the PLB.
