Red blinking LED

[FCPhantom]

Hi

Yesterday I was flying my Fc40 Phantom. After warm-up, there was single green blinking LED, I lift it up, and on the air Phantom flashes few time red LED. Is that sign for poor GPS signal, or what? Phantom was all the time in GPS mode.

One or two red flashes during flight means weak gps signal

Rapid flash red means land as the battery is weak
