Question: How to plot the Bode plot of this transfer function with Maple 15?

> restart:
with(DynamicSystems):
> sys := TransferFunction(1/((1+0.1*s)(1+0.002*s+0.0001*s^2)));
> BodePlot(sys,range=10^(-1)..10^(3));

I get the following warning:
 
             Warning, transfer-function(s) are not rational-polynomial(s) in s



Why?.. How can I make it work without any warning?

Thanks everybody for help!
