4. OPERATION
The emergency locator transmitter is power-supplied by two disposable lithium battery packs.
The emergency locator transmitter can be operated :
- manually, either by setting the "MAN/RESET-OFF-AUTO" transmitter switch to "MAN/RESET" or by
setting the S130 "ELT" remote control switch to "MANUAL" (the "MAN/RESET-OFF-AUTO" transmitter switch being set to "AUTO"),
- automatically, in the event of an impact, when both switches are set to "AUTO".
Once triggered, the emergency locator transmitter transmits a modulated signal simultaneously on both emergency frequencies (121.5 MHz and 243 MHz).
When the "MAN/RESET-OFF-AUTO" transmitter switch is set to "OFF", transmission can no longer take place.
