I'm not sure if there is a way to do it with SyncML but you may be able to set it up with your bluetooth config on your PC, there is a setup feature with the bluetooth to power on and off but I am not sure if I have mine on a schedular. I know you can set it up to autosync whenever the phone comes into range of the bluetooth, but as far as time schedule I am not sure. Basically what I am saying is check your bluetooth manager software.
