B1900D checklist,

In the checklist for the B1900D under before engine starting I'mtold to switch on anti ice and beacon and then check anti ice annunciators is illuminated.As far as I can see this is not possible if the battery switch is not turned on. That is next step in the checklist. Also here you are again told to switch on beacon.At takeoff you are supposed to set power levers to 100% torque. Thisis not possible with anti ice on. Does this mean I should switch offanti ice before takeoff?During normal landing I'm told to set 30% torque and set power level to idle. But I need to set the powerlever little over idle to get 30% torque. Which should I do?RegardsJan Friberg
