3.3.5.2 Transmitter Self-Test:
Turn and hold the main switch, from the "OFF" position to the "SELF TEST"
position. The Green ON light shall illuminate for 4 seconds then extinguish. This is to
allow coding programming during next 20 seconds window and self-test for 1 second
thereafter.
The ELT-(S) may be coding programming during the aforementioned 20 seconds
window period. If no programming happened the ELT will then enter the Self Test
Mode for 1 second thereafter.
Self-test results after (4+20+1) =25 seconds, is:
If the self-test is passed,
the Green ON LIGHT is steadily extinguished. ELT swept
Tone must be silent on the 121.5 MHz VHF Radio.
If the self-test is failed,
the Green ON LIGHT flashes as shown below:
1 flash:
Internal Data stored in Memory at fault.
2 flashes:
Distress ID stored in Memory at fault.
3 flashes:
Battery voltage is low < Useful Life Battery Voltage setting.
4 flashes
: Vcc supplies for F3, F2, or F1 at fault.
5 flashes:
F3 RF power level < 33 dBm @ 406.028 MHz
7 flashes:
F1/F2 VHF RF power level < 17 dBm @ 121.5/243 MHz.
9 flashes:
PLL locked in F3 or F1 or F2 at fault.
Continuous flash:
no F3/F2/F1 RF output power, ELT shuts down completely.
Note:
The self-test mode that transmits a 406 MHz test code pulse monitors certain system
functions before returning to the SELF TEST mode. The 406 MHz test pulse is
ignored by any satellite that receives the signal, but the ELT-(S) uses this output to
check output power and correct frequency.
Self-test is 520 ms long message burst on the 406 MHz signal. Synchronization
pattern is 011 010 000.
Self-test is then 121/243 MHz (VHF) Continuous Wave during 1s.
During Self Test, the ELT swept Tone is silent on the 121.5 MHz VHF Radio.
The ELT-(S) may accept GPS position input by connecting the external GPS to the
Remote connector
