Activation (406 MHz and 121.5 MHz)
To activate your beacon in a distress situation, follow these steps:
1) Unfasten the antenna from the case.
2) Move it into the upright position (see figure 3 below).
3) Depress the ON/OFF
You will hear a BEEP and your beacon is now activated. While transmitting your distress signal, the red LED
will flash once every 2 seconds alerting you that your beacon is active. An additional BEEP will sound every
time your beacon transmits data to the satellites (roughly every 50 seconds).
406/121.5 Antenna Position
For maximum performance you must deploy the beacon antenna into the proper position (see figure 3). If at all
possible, be sure the antenna is positioned facing the sky and avoid submerging in water. This device is
intended to operate on or above the ground or while attached to your person above the water line.
Activation with GPS
Your beacon is equipped with an internal GPS receiver. Once activated, the GPS engine will start up and
search to find your LAT/LON and incorporate it into your 406 MHz signal. As soon as the GPS receiver
acquires good positioning data the red LED will stop blinking and the green LED will begin flashing once every
The same GPS data will be sent with each 406 MHz signal for the next twenty minutes. At that time the
internal GPS will start up again, search to find your LAT/LON and incorporate it into your next 406 MHz signal.
If for any reason the internal GPS cannot update your LAT/LON, your last position will be used for the next
four hours. At that time the green LED will stop blinking and the red LED will flash once every 2 seconds until
new GPS data is obtained.
