After doing a compass calibration there are 2 possible outcomes according to the user’s manual. 1. LED Flight indicator = Normal Led = Succeeded 2. LED Flight indicator = Red, Yellow flashing in turn = Failed I’m getting a 3rd, LED Flight indicator = Only ONE flash Red followed by Yellow flashing until the satellites lock in, then steady flashing green. LEDs are not alternating red & yellow but the initial flash of red doesn’t seem right. Is this normal?
