The 121.5 MHz signal is used by SAR to home in on the beacon as they approach it. The 406 MHz signal is detected by multiple satellites and from that information the location of the beacon can be calculated. This data alone is sufficient for SAR to find persons or ships in distress in a reasonable timeframe. 2. Anatomy of your beacon NOTE: When unpacking your beacon, it is recommended that you save the original packaging for re-use when shipping the beacon for battery replacement in the future.

Refer to Table 2 for proper wire size for connection of the input power lines. NOTE: As per the wiring scheme, the ORANGE wire is connected to the positive terminal and the BLUE wire is connected to the negative terminal of the power source. CAUTION: HID light systems, when first turned on, have a high inrush current requirement of 25 amps. If you activate the light and the lamps flicker on and off repeatedly, check the voltage being supplied. This condition can be experienced with voltage input

The demodulated 121.5 MHz audio signal is annunciated at all times. If there is not any signal on the 121.5 MHz carrier, whether activated beacon or other source, static will be audible. The speaker volume is high, and the signal strength meter is active. Monitor Low mode This mode is identical to the Monitor High mode except that the speaker volume is lower. NOTE: The ARX-50 reverts back to Alarm mode after 15 minutes in Monitor High mode. Training mode Operation in Training mode is identical t

At the same time the 406 MHz signal is activated, a 121.5 MHz signal is turned on. The 121.5 MHz signal is used by SAR to home in on the beacon as they approach it. The 406 MHz signal is detected by multiple satellites and from that information the location of the beacon can be calculated. This data alone is sufficient for SAR to find persons or ships in distress in a reasonable timeframe. However, as a further enhancement, some beacons have a GPS engine onboard. This feature allows the beacon t

Repeated activations could be viewed as a hoax. 11. Preventing false alerts A false alert is any activation of the beacon, intentional or otherwise, that does not result from a situation of grave and imminent danger. Be sure to do the following to help minimize false alerts: . Register your beacon. This does not reduce false alert rates; however, when the beacon is properly registered, the situation can usually be resolved with a phone call. . Be careful with whom you leave your beacon. Make sur
