4. Operating Instructions
4.1 Power On/Off
The unit features an ON/OFF switch. Slide the switch to the 'ON' position to power the unit and connected motors. Slide to 'OFF' when not in use to conserve battery.
4.2 Motor Control
The integrated unit has two-position switches to control motor direction (forward/reverse) and speed. Each switch corresponds to a motor output.
- Switch 1 (Top): Controls the internal motor or the primary connected motor. Move the switch to one side for forward motion, the other side for reverse, and the center for stop.
- Switch 2 (Bottom): Controls the secondary connected motor. Similar to Switch 1, move it to control direction or stop.
You can control both motors together or independently using these switches.
4.3 Remote Control (Optional)
This unit supports control via a compatible remote control (sold separately). While the unit itself does not include a remote, it is designed to integrate with existing MOC Power Functions remote systems. Ensure your remote is compatible with the Power Functions standard.

7. User Tips
- Integrated Design: Take advantage of the integrated motor and lithium battery box. This compact design means you don't need a separate battery box, simplifying your MOC builds.
- Dual Functionality: Remember that the unit can act as a standalone motor and also as a power source for an additional motor. This allows for more complex movements and power distribution in your models.
- Independent Control: Utilize the two-position switches to control two motors (the internal one and an external one) either simultaneously or independently, providing fine-tuned control over your creations.
- Small Parts Warning: This product contains small parts. Exercise caution during assembly and operation, especially around younger children, to prevent choking hazards.
