spektrum DX3R and SR3100
 

Hi I've got a Spektrum Dx3r transmitter and SR3100 receiver they have been used for about 5-6 meeting and had no problems.

The other day I changed the batteries (4 AAs) and now when I try to use it the car won't pick it up theres a light on the esc so I know thats all fine.I've tried resetting and binding again but its just a solid orange light when a flashing orange light is ready to bind?
I don't know if it was because I changed the batteries? :confused:

Hopefully I've missed something and its a simple solution :(

Please help and let me know what you think
