Perform Transmitter Tests (Self Test)
Self tests must be performed outside of metallic enclosures and at least 2 meters away
from large metallic surfaces which may reflect electromagnetic waves. If restrictions are
not observed it is possible that self test may report failure when the beacon is operating
properly.
Following are step-by-step instructions for performing the field tests.
1) Examine the SLB 406 closely for signs of physical damage including cracked or
punctured housing, cracked or broken face plate or damaged antenna.
Note: The antenna is not intended to be removed from the ELT by the user.
2) Perform Self-test by pressing the self-test button (see Figure 7) for two seconds, then
releasing the button.
3) Observe the red XMIT LED. It will light up for one second as acknowledgement.
4) The Pass LED and the Fail LED will then light up together for one second. After this,
at different stages of the test, the other LEDs glow steadily or flash depending on the
particular self-test being performed.
5) Check for Pass/ Fail. After five seconds, either the ‘Pass’ or the ‘Fail’ LED will start
flashing for sixty seconds, the green LED for pass and the red LED for fail.
