Could not compile stylesheet for timeless. Using last compiled stylesheet.

I am using Bumblebee radar, I adjust the potentiometer to extend the detection range to 6 meters. As I read in user manual, I can ground the J1-4 pin to maximize the detection range, and I connected J1-4 to U2B, but It does not work.
Hope someone can tell me how to solve the problem.

By: Nathan StohsIf all you want to do is maximize range using the potentiometer is the recommended method. Simply turn it fully clock-wise and leave J1-4 floating.
J1-4 is for automated range control from a DAC (e.g. from a microcontroller). If this is what you want to do I will need more information. I don't understand what you mean exactly by "U2B", that is a part, not a net. Can you connect a ground from your power supply to J1-4? Secondly, when it doesn't work, what happens instead? Does the whole radar fail or it works but you think the range is not correct? -

By: Nathan StohsIt occurs to me that by "U2B" you meant U28 on a Tmote Sky, and hopefully one of the DAC pins. Can you verify that the DAC is pushing 0v, and if its not working, what is happening instead?
