Selecting and adjusting light effects on the Velleman VM120 12V Light Effect Generator is straightforward. Here's a guide:
Choosing Light Patterns: Use the 'Effect select' pushbutton switch (SW1) to cycle through the ten pre-programmed light patterns. Press and hold SW1 to view the currently selected effect; the corresponding will illuminate. Release SW1 to activate the chosen effect. Briefly press SW1 again to move to the next effect. You can also use SW2 to activate or deactivate all channels simultaneously. Remember that pressing SW1 will restart the selected light effect.
Adjusting Speed: Fine-tune the speed of the light effects using the RV1 control. This allows you to customize the pace of the light patterns to your preference.
Effect Memory: The Velleman VM120 conveniently saves your last selected effect in its internal memory. This means that if there's a power interruption, your preferred setting will be retained.
Random Effect Selection: For a random light display, press and hold SW2 while powering on the device. Note that this feature will disable the standard pre-programmed patterns.
