SECTION 4 - OPERATION
4.1 General
The TerraFix™ 406 GPS PLB models are designed to be manually deployed and activated. It is
only to be activated when all other means of self-rescue have been exhausted. Activation of the PLB
tells Search and Rescue who you are, where you are, and that you are facing a life threatening
situation.

4.2 TerraFix™ 406 GPS PLB Emergency Activation
4.2.1 Activation
To activate your PLB in an emergency situation, unfasten the antenna from the case or holster and
move it into the upright position (See figure 2). Lift the holster cover revealing the PLB keypad (see
figure 3). Depress the "self-test" and "GPS I" or "GPS I/O" buttons simultaneously for at least 1/2
second and less than 5 seconds (see figure 4). Your PLB is now activated. While transmitting your
emergency signal, the red LED will flash once every 2 seconds alerting you that your PLB is
activated. If GPS data is present in the PLB via the GPS I or GPS O the red LED will turn off and
the green LED will take over flashing once every 2 seconds.
4.2.2 Activation with GPS I (P/N 2798.2 and P/N 2798.4)
The TerraFix™ 406 GPS I and GPS I/O are equipped with a GPS Interface. Prior to activating
your PLB you can download your GPS LAT/LON into the PLB using an external GPS receiver and
the GPS Interface cable provided with the PLB. Once your external GPS has acquired good global
positioning data, press the GPS test button for at least ½ second and no longer than 5 seconds and
your GPS data will download into the PLB (for full instructions see Section 4.7.2). Once you
activate your PLB, your GPS coordinates are included in the distress signal. The green LED will
immediately start flashing every 2 seconds to alert you that your PLB is activated and transmitting
your GPS coordinates with the 406 MHz signal.
