The standard power cord for the SI units and some of the more sofisticated non-SI units is the PC-11.
It has the built-in choke and larger conductors.
The other power cord is the PC-10.
Either one works fine for in-home Simulator use.
The Demo mode is worthless for learning, Turn that off and use Simulator.
You need a power supply that has 1 1/2 amp capacity it seems for newer units. Someone posted on another site that a 1A would not start up his 898.
I use 1A converters at home and doing demos, with my 1198 units and 798.
