HELP Turnigy Trackstar GenII 120A 1:10

[spiboom85]

Hi please forgive me before I come across a numpty , This may be easy to sort out

iv bought a roller tm2 v1 that came with a free Turnigy Trackstar GenII 120a speedo and motor, as wasn't sure if was working

now I am new to all this so a friend has put the motor on his esc and it works fine

now the speedo red light comes on my hand set has been bind to the receiver and I have full motion in regards to the steering

with out the hand set switched on the I connect the battery, speedo comes on solid re light with a one bleep / noise

Soon as I switch my handset on the red light on the speedo keeps flashing and beeping, I if I put on the throttle it does nothing just keeps beeping until I unplug

has or does anyone know what I need to do or could this be broken ?

I just want to buy a new one if this just needs setting up

thanks again steve
