13. Fail-safe function
If the receiver/control unit does not receive a correct signal from the transmitter, the motor switches off for safety
reasons (the servo for the steering function remains in its last position).
Reasons for the activation of the fail-safe function include:
• The receiver is too far away from the transmitter
• Interference at the 2.4 GHz frequency from other devices
• The transmitter is switched off
• Receiver is not paired to the transmitter (see section 12)
• Thebatteriesinthetransmitterareat

to protect the drive battery against a harmful deep discharge.
In this case, turn the vehicle off and disconnect the drive battery from the vehicle and then charge it again (before the
empty battery is charged, allow the battery to fully cool down).
