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 operating instructions
included with the product.
The model does not respond or does not respond correctly
• 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 drive battery or the remote control batteries empty? If so, replace the drive 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 drive 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remotecontrol,aminimumrangeof50mshouldbepossible.However,thiscanbereducedbyoutsideinu-
ences,suchasinterferenceontheradiofrequencyortheproximityofothertransmitters(notonlyremotecontrol
transmitters, but also WLAN/Bluetooth
®
devices that also use a transmission frequency of 2.4 GHz, of metal parts,
buildings, etc.).
Thepositionoftheremotecontrolandreceiveraerialsrelativetooneotheralsohasasignicant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signicantly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).
The vehicle doesn’t stop when the throttle/brake lever is released
• Correct the throttle trim on the remote control (set the neutral position).
The vehicle travels slowly or the steering servo does not respond properly to remote control commands; the
range between the remote control and the vehicle is very short
• Thevehiclebatteryisnearlyempty.
ThereceiverandthesteeringservoarepoweredbytheBECinthespeedcontroller.Asaresult,thereceiverwill
not function properly when the drive battery is nearly empty. Replace the drive battery with a fully charged battery
(beforechangingthebattery,waitforatleast5–10minutesfortheengineandspeedcontrollertocooldown).
• Check the batteries/rechargeable batteries in the remote control.
