16. Troubleshooting
The model vehicle was manufactured using the latest technology, However, faults and malfunctions may still occur.
The following section shows you how to troubleshoot these issues.
The model does not respond or does not respond correctly.
•
2.4 GHz remote control systems require the receiver to be paired with the remote control. The receiver automati-
cally pairs with the remote control when the remote control and vehicle are switched on. It is not necessary to pair
the devices manually.
Ensure that you do not turn on other similar vehicles at the same time, otherwise the remote control will not be able
to detect the correct vehicle. Turn on the remote control, and then switch on the corresponding vehicle to start the
pairing process (the LED on the remote control will stay constant). Once the pairing process is complete, you can
turn on another remote control for the next remote control/vehicle combination.
•
Is the vehicle battery or the remote control batteries empty? Replace the vehicle battery or remote control batter-
ies. For safety reasons, we recommend using disposable batteries for the remote control rather than rechargeable
batteries.
•
Did you switch on the remote control before switching on the vehicle?
• When the remote control is switched on, the LED on the remote control will flash and the vehicle will connect to the
remote control (also known as "pairing"). The LED will stay constant when the pairing process is complete, after
which you can use the remote control to drive the vehicle.
•
Is the drive battery connected to the speed controller? Check the plug connections to see if they are dirty or rusted.
•
Is the vehicle battery fully charged?
•
If the vehicle stays stationary, the undervoltage protection may have been activated due to a low battery voltage
(the engine turns off when the battery voltage drops below 6.4 V). Connect a new fully-charged battery to the vehi-
cle (wait at least 5 - 10 minutes to allow the electronic components and the engine to cool down.
•
Is the vehicle too far away? The range should be at least 50 m when the vehicle battery and the remote control
batteries are full. However, environmental factors may reduce the range. These include interference on the trans-
mission frequency or proximity to other transmitters (including Wi-Fi/Bluetooth
®
devices that use a transmission
frequency of 2.4 GHz), metal objects, buildings and other obstacles.
• The position of the remote control and receiver antenna 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.
•
For safety reasons, the receiver/control unit switches the engine off when there is no signal from the remote control.
The vehicle doesn’t stop when the throttle/brake lever is released.
•
Adjust the "THROTTLE TRIM" control dial on the remote control so that the vehicle stops when the throttle/brake
lever is in the neutral position.
The vehicle stops suddenly
•
The undervoltage protection feature was activated because the vehicle battery is empty. Replace the vehicle bat-
tery with a fully-charged battery (wait 5 - 10 minutes to allow the engine and electronic components to cool down).
•
The receiver did not receive a signal from the remote control; the drive was disabled for safety reasons. The vehicle
is too far from the remote control, the remote control batteries are empty, or the remote control was switched off.
