TRANSMITTER SETTINGS
Setup the following basic functions on your transmitter (if available):
If your transmitter doesn‘t offer any of above functions, it‘s already in „basic setup“ mode.
• Ensure that the speed-control is not connected to the drive battery and is switched off.
• Remove motor pinion or ensure that the wheels of the model are free to rotate.
• Switch the transmitter on and set the transmitter throttle stick to neutral.
• Connect the speed-control to the battery and switch the unit on.
• Hold the SET button pressed for at least 3sec using the supplied plastic screwdriver.
You entered setup mode and the LED flashes green (it will flash until the setup is completed).
• Leave transmitter in neutral position and press the SET button once.
Neutral setting is stored , LED flashes green and the motor beeps.
• Hold full throttle on transmitter and press the SET button once.
Full-throttle setting is stored, LED flashes green.
• Hold full brake on transmitter and press the SET button once.
Brake setting is stored, LED glows green.
• This completes the setup procedure and your LRP IPC GEN series speed-control is ready
to use.
• If you have made a mistake so far, don’t worry: Switch off the speed-control for about 10 seconds
and start over again.
• After the run, first switch off the speed-control, unplug the battery and then switch off the transmit-
ter. When you start again, first switch on the transmitter, then plug in the battery and switch on the
speed-control.
• Always disconnect the drive battery from the speed-control, if you are not using your model.

7. SPECIAL FEATURES
APC Adjustable Power Control
It is very easy to loose control of a model car on a slippery track surface if you are running a powerful
motor. The adjustable power control provides the solution. The unique LRP APC (Adjustable Power
Control) effectively prevents unwanted spins and slides, improves vehicle control and thus improves
your lap times and extends running times.
Adjusting the APC system:
• For maximum power - rotate the power potentiometer carefully to the right-hand stop using the
plastic screwdriver supplied.
• If your car tends to spin - you need slightly less power when accelerating. Rotate the power poten-
tiometer to the left until you can control your car during acceleration.
• If your car has a powerful motor and your speed control switches into temperature protection (over-
load protection) - rotate the power potentiometer about 1/3 of a turn to the left.
Note:
The APC function has no effect on the car’s maximum speed.
Multi-Protection System, 3-way protection
The perfect protection against short-circuits (motor), overload and overheating. If your speed-control
faces one of these problems, the motor function will be shut-off for protection and the LED will flash.
The steering function will be maintained. Let everything cool down for a few minutes.
If the speed-control switches off frequently, either the used motor is too strong, the motor pinion is
too big or you are using full brake too often. You can improve this if you make additional cooling slots
in the body.
Improved Brake Feel
All the LRP IPC GEN series speed controls feature a fully proportional EMF brake which can
be applied very smoothly to maintain good grip on slippery surfaces. Thanks to the Advanced Digital
technology, it was possible to improve the brake feel of the LRP IPC GEN series speed con-
trols even more.
Advantages:
• Smooth, proportional braking
• Superior braking power
• Battery recharge during braking
If the braking power is too strong for your driving style and conditions, you can reduce it by adjusting
servo travel at the transmitter.
