7. Sending a Panic Alert
You can request help by pressing certain buttons on the PLD. The PLD then issues a
Panic Alert signal, which is detected by the Command and Control system. The Panic
Alert function uses the PLD’s GPS antenna. Therefore, the PLD unit needs a clear
view of the sky when a Panic Alert message is sent.
