From your quote I understand that it depends on whether you have a KD-1902 (=> no) or a KD-2902 (=> yes).
Added - RM:
You do not say what country you are in or what your mains voltage is.
The two main choices are "around 100 VAC" and "around 230 VAC".
The KD2902 machine will operate on voltages around 230 VAC.
The KD1902 machine will operate on voltages around 110 VAC.
The two are not interchangeable by simply changing the plug.
IF your local power supply is in the 210 VAC to 240 VAC range then you can probably use the machine in Europe.
IF your local power supply is in the 110 VAC to 120 VAC range then you can probably NOT use the machine in Europe.
A 110VAC rate machine can be used on 230 VAC with a suitably rated 230 to 110 VAC transformer but the cost of this may make it not worthwhile.
What country are you in?
What is your local mains voltage.
