Abhijeet, I've looked at the RF230 manual, and 0xF is the lowest power setting. If this transmission range is not low enough, then the only thing I can think of that you can do is attenuate the signal at the antenna. You could try either covering the antenna in tin foil, or removing the antenna altogether.
