12. Troubleshooting
Even though the model and the remote control system were built with the latest available technology, there can still
bemalfunctionsorerrors.Forthisreason,wewouldliketogiveyousomeinformationonhowtodealwithpossible
problems. Also observe the enclosed operating instructions for the remote control system.
The model doesn’t respond or does not respond properly
• For2.4GHzremotecontrolsystems,thereceivermustbetaughttothetransmitter.Thisprocessmaybereferred
to by the terms of "Binding" or "Pairing".
 Theteachingprocessusuallywasperformedbythemanufactureralready;however,itcan,ofcourse,alsobedone
by you. Also observe the separately enclosed operating instructions for the remote control system.

drive battery or batteries/rechargeable batteries in the transmitter for new ones.

of safety in case of reverse order.
• Isthedrivebatteryconnectedtothespeedcontrollercorrectly?Checktheplugconnectionsforwhetheritiscon-
taminated or oxidised.
• Isthedrivebatteryfullycharged?Thisvehicleneedseithera6-cellNiMHdrivebattery(ratedvoltage7.2V)ora
2-cell LiPo drive battery (rated voltage 7.4 V).

interference on the transmitter frequency, or proximity to other transmitters (not only remote controller transmitters
but also WLAN/Bluetooth devices that also use a transmission frequency of 2.4 GHz), metal parts, buildings, etc.

transmitter and receiver aerial are vertical. If you point the transmitter aerial at the vehicle, the range will be very
short!
• Checkthecorrectpositionofthespeedcontrollerandsteeringservoplugsinthereceiver.Iftheplugsareinserted
rotated by 180°, the speed controller and steering servo will not work.
If, however, the speed controller and steering servo plugs are swapped, the throttle/brake lever at the transmitter
controls the steering servo, and the wheel controls driving!
The vehicle does not stop when the throttle/brake lever is released
