work(s), verify that power is connected, and wait for the device to boot up.

1. Check the front panel status LED indicators:
The Power LED should be lit (not flashing).
The GNSS LED will be either OFF or flashing HEARTBEAT, since
synchronization has not yet been achieved.
The Alarms LED light should be OFF (startup behavior) or
HEARTBEAT (acquiring fix behavior). A FAST blinking pattern would
indicate the unit requires attention.
