I am a new drone owner. Purchased the Phantom 3 SE Charged the craft battery and remote.  Had a couple 2 minute flights, set for a little while (3months) Recharged the craft battery and remote. After recharging the remote, remote showing full charge (green light)... turn on the remote and it starts flashing a red light and beeping. I did charge the remote with a generic micro charger, just not sure if this had something to do with it? Can't seem to find any info on a fix or what?  Any help is appreciated.

Are the rc linking to handset or aircraft at tat time while the beeping starts？

the red light is because the RC IS NOT conected to the drone ... this red light with the RC full charged mean this ...
