SECTION 4 - OPERATION
4.1 General
The AeroFix™ 406 GPS P-ELT 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
P-ELT tells Search and Rescue who you are, where you are, and that you are facing a life threatening
situation.

4.2 AeroFix™ 406 GPS P-ELT Emergency Activation
4.2.1 Activation
To activate your P-ELT 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 P-ELT 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 P-ELT is now activated. While transmitting
your emergency signal, the red LED will flash once every 2 seconds alerting you that your P-ELT is
activated. If GPS data is present in the P-ELT 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 2799.2 and P/N 2799.4)
The AeroFix™ 406
GPS I and GPS I/O are equipped with a GPS Interface. Prior to activating your
P-ELT you can download your GPS LAT/LON into the P-ELT using an external GPS receiver and
the
GPS Interface cable provided with the P-ELT. 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 P-ELT (for full instructions see Section 4.7.2). Once you
activate your P-ELT, your GPS coordinates are included in the distress signal. The green LED will
immediately start flashing every 2 seconds to alert you that your P-ELT is activated and transmitting
your GPS coordinates with the 406 MHz signal.
