14. Troubleshooting
This model was built using the latest technology. However, faults and malfunction may still occur. The following section
shows you how to troubleshoot potential problems. Ensure that you also read the remote control instructions included
with the product.

• In the case of 2.4 GHz remote control systems, the receiver must be connected to the remote control. This process
is known as "pairing". The manufacturer pairs the remote control with the receiver before the vehicle is shipped.
However, you can also pair the remote control yourself. To do this, follow the enclosed operating instructions for
the remote control.
• Is the vehicle battery or the remote control batteries empty? If so, replace the vehicle battery or remote control
batteries.
• Did you switch on the remote control before switching on the speed controller? For safety reasons, the speed
controller does not function if this is done in the reverse order.
• Is the vehicle battery connected to the speed controller? Check the connection to see if it is dirty or rusted.
• Is the vehicle too far away? With a fully charged drive rechargeable battery and batteries/rechargeable batteries
in the transmitter, a minimum range of 50 m should be possible. However, this can be reduced by outside influ-
ences, such as interference on the radio frequency or the proximity of other transmitters (not only remote control
transmitters, but also WLAN/Bluetooth
buildings, etc.).
The position of the remote control and receiver aerials relative to one other also has a significant impact on the
range. For best results, the remote control and receiver aerial should be vertical (i.e. parallel to each other). Pointing
the remote control aerial at the vehicle significantly reduces the range.
• Check the correct position of the speed controller plug and steering servo on the receiver. If the plugs have been
rotated 180°, the speed controller and steering servo will not work.
If the connectors for the speed controller and steering servo are connected the wrong way round, the throttle/brake
servo will control the steering servo (and vice versa).
• Check the correct position of the speed controller plug and steering servo on the receiver. If the plugs have been
rotated 180°, the speed controller and steering servo will not work.
• Reset the speed controller to its default settings (see chapter 10. c). Then reprogramme the neutral position and the
full forwards and full reverse throttle positions; see chapter 10. a).
The vehicle doesn't stop when the throttle/brake lever is released
• Correct the throttle trim on the remote control (set the neutral position).
• Reprogramme the neutral position and the full forwards and full reverse throttle positions; see chapter 10. a).
