15. Troubleshooting
Even though the model and the remote control system were built with the latest available technology, malfunctions or
faults may still occur. We would, therefore, like to show you how to correct potential faults.
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 transmitter. This process is
known as "pairing". On this vehicle, pairing is carried out automatically after switching on the transmitter and the
vehicle. Manual pairing is not necessary.
Ensure, however, that multiple similar vehicles are not being operated at the same time as the transmitter will not
then know which vehicle belongs to the transmitter. First, switch on a transmitter, followed by the corresponding
vehicle so that pairing can take place (the LED on the transmitter lights up continuously). Only then can the next
transmitter/vehicle combination be operated.
•
Are the drive batteries in the vehicle or the batteries in the transmitter depleted? Replace the drive batteries or the
batteries in the transmitter. For safety reasons, we recommend using disposable batteries in the transmitter and
not rechargeable batteries.
•
Did you switch the transmitter on before switching the vehicle on?
• The LED on the transmitter flashes after the transmitter has been switched on. Then, switch the truck on. The
vehicle is now connected to the transmitter (also known as "pairing"). Only when the LED on the transmitter lights
up continuously can the vehicle be controlled with the transmitter.
•
Are the drive batteries fully charged?
•
If the vehicle remains stationary when driving, the low-voltage detection may have been activated as the voltage
of the batteries is too low (the motor is shut off if the battery voltage falls below approx. 3.2 V). Insert two new, fully
charged drive batteries into the vehicle (wait at least 5 - 10 minutes for the electronic system and the motor to cool).
•
Is the vehicle too far away? With a full drive battery and full batteries in the transmitter, a transmission range of 50 m
or more should be possible. However, this can be reduced by outside influences, 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 transmitter and receiver antennae relative to one other has a very strong impact on the range. Ide-
ally, both the transmitter and the receiver antennae should be vertical (and thus both antennae are parallel to one
another). Pointing the transmitter antenna at the vehicle significantly reduces the range!
•
If there is no transmitter signal, the receiver/control unit switches the motor off for safety reasons.
The vehicle does not stop when the throttle/brake lever is released
•
On the transmitter, correct the "THROTTLE TRIM" dial for the drive function so that the motor remains stationary
when the throttle/brake lever is in the centre (neutral) position.
The vehicle stops suddenly
•
The undervoltage protection has been activated, the drive batteries are depleted. Replace both drive batteries with
new, fully charged drive batteries (before inserting a new drive battery, wait at least 5 - 10 minutes so that the motor
and electronic system in the vehicle can cool).
•
The receiver has no valid signal from the transmitter; the drive mechanism has been deactivated for safety reasons.
The distance between the vehicle and transmitter is too large, the batteries in the transmitter are weak/depleted or
the transmitter has been switched off.
