RECCO is a rescue technology used by organised rescue teams as an additional tool to more quickly locate people buried by an avalanche or lost in the outdoors.[2] The system is based on a harmonic radar system and composed of a detector and a passive reflector integrated into outdoor clothing and gears.[3]

was invoked but never defined (see the help page).RECCO detector's transmitter uses the frequency 902.85 MHz … used for example by the "Intelligent Transportation Systems Radio Service". … In Europe, the RECCO detector uses the frequency 866.9 MHz … reflectors are the same all over the world. … pulsed radio signal at 20% duty cycle and the RECCO system is "silent" 80% of the time (it repeatedly transmits for 20 milliseconds and is silent for 80 milliseconds). … the reflector will re-radiate a signal power of approximately 10 nanowatts … around the frequency 1805.7 MHz. … reflector measures approx. 60x20x2 mm. … all objects containing a diode and a metallic structure will react in the same way as the RECCO reflector. … for example if they have a digital camera or a cell phone (no difference if they are switched on or off). … In Europe, several people have been rescued alive even though they were not wearing any RECCO reflectors, but only carrying some other electronic device like a camera, an MP3 player or similar … maximum distance for detecting an avalanche victim, wearing a RECCO reflector, is around 20‒40 meters.
