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.
The model doesn't respond or does not respond properly
• Are the rechargeable batteries in the vehicle or the batteries/rechargeable batteries in the transmitter discharged?
Exchange the rechargeable batteries in the vehicle or batteries/rechargeable batteries in the transmitter for new
ones.
• If you are using two AA/Mignon rechargeable batteries for the transmitter, try using two batteries instead. The lower
voltage of the rechargeable batteries (rated voltage NiMH rechargeable battery = 1.2 V, battery = 1.5 V) may cause
functional problems.
• Did you switch on the transmitter first and then the vehicle? The vehicle may not work properly if the order is re-
versed.
• Are the rechargeable batteries properly inserted in the vehicle?
• Are the rechargeable batteries for the vehicle fully charged? This vehicle needs two Li-Ion rechargeable batteries of
the same build, of type "17500" (rated voltage 3.7 V).
Always insert two rechargeable batteries of the same build in the vehicle, both of which must be fully charged.
Never use rechargeable batteries with different charge states in the vehicle. If the vehicle is then used, this
may cause deep discharge of the rechargeable battery with the lower charge. Deep discharge of a Li-Ion
rechargeable battery will render the rechargeable battery useless!
• If the vehicle stops when driving, the undervoltage recognition may have been activated since the voltage of the
inserted rechargeable battery is too low. Replace the two rechargeable batteries by new, fully charged ones.
• Is the vehicle too far away? With fully charged rechargeable batteries in the vehicle and fully charged batteries in
the transmitter, the range should be 50 m and more. The range can be decreased by outside influences, such as
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.
The position of transmitter and receiver aerial to each other very strongly influences range. It is best when both the
transmitter and receiver aerial are vertical. If you point the transmitter aerial at the vehicle, the range will be very
short!
The vehicle slows down or the steering servo shows only slight or no reaction; the range between transmitter
and vehicle is very short
• The rechargeable batteries in the vehicle are weak or empty.
The receiver power supply and thus also the power supply of the steering servo is achieved through the recharge-
able batteries in the vehicle. Therefore, weak or discharged rechargeable batteries will cause the receiver to no
longer work properly.
Replace the rechargeable batteries by two new, fully charged ones (before inserting a new drive battery, wait at least
5 - 10 minutes until motor and speed controller have cooled down sufficiently).
• Check the batteries/rechargeable batteries in the transmitter.
