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 I

nterface 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.
