Connection to the Receiver
Connect the three-pin plug (4) of the speed controller to the corresponding channel of the
receiver.
Make sure the assignment on the receiver is correct (see operating instructions of the receiver
as well as the information on the receiver).

The speed controller has a BEC (= „Battery Eliminator Circuit"; electronic circuit for
power supply to the receiver right from the drive battery).
If the BEC is used as power supply of the receiver, no separate receiver battery or
rechargeable battery must be used!
Important!
If a separate receiver power supply is to be used instead of the integrated BEC, the
middle, red, cable of the three-pin receiver plug of the speed controller must be
interrupted and isolated (e.g. with a piece of shrink hose). If this is not observed, the
speed controller will be destroyed! Loss of guarantee/warranty!
The speed controller has no undervoltage cut-off. If you do not stop driving in time,
deep discharge of the rechargeable battery and/or interferences of the receiver
system threaten due to fluctuating or too-low BEC voltage.
Deep discharge may destroy a battery over time as well. Therefore, we recommend
that you install a battery voltage monitor that signals undervoltage with LEDs. See our
catalogues or our website at www.conrad.com for matching accessories.
Programming
The indicator LED (5) at the front of the speed controller informs you of the respective switching
conditions of the speed controller during operation.
The speed controller should not be connected to the motor during programming. Connect the
speed controller to the corresponding receiver output. Switch on the transmitter and check the
throttle lever position. It should be set to „motor off" (centre). Now connect the rechargeable
battery to the speed controller.
Neutral point setting
In most cases, the throttle lever at the remote control is automatically put in the neutral position
(motor off) by spring force. For some remote controls, this neutral point can be relocated in the
direction of reverse driving to provide a longer setting path for fine control of forwards driving.
Release the throttle lever so that it is in the neutral position at your transmitter; do not move it.
Switch on the speed controller with the on/off switch (3). The neutral position is recognised and
determined at once by the speed controller. Programming is complete.
The neutral position settings are not saved. Every time the speed controller is switched
on, the current position of the throttle lever at the transmitter is recognised as the new
neutral point.
Set/Check full throttle position for forwards driving
The full throttle position for forwards driving is automatically calculated by the speed controller.
For verification, move the throttle lever into the full throttle position for forwards driving. If it
functions correctly, the indicator LED (5) will flash.
If the indicator LED does not flash but remains lit, this is the speed controller's reversing function.
In this case, operate the servo reverse function for the respective channel at your transmitter and
repeat programming.
Set/Check full throttle position for reverse driving
Push the throttle lever at the transmitter into the full throttle position for reverse driving. The
position of the throttle lever is automatically recognised by the controller. The indicator LED (5)
remains lit.
Reverse driving does not use the full output for the drive motor.
End of Operation
• First switch off the speed controller (put switch in the „OFF" position).
• Disconnect the battery from the speed controller.
• Now switch off the transmitter.
Disposal
Dispose of the product according to the applicable statutory provisions at the end of
