how to use "keep out"？

As my pc set with English system,can't write with CH,I'm so sorry！

to PCB,I'm a fish,

can you give me the detail of keep out ?please

Keep out是一个闭合的区域，而不是一条线，so,

画keep out时，要画闭合。

PS：

English System can type and display Chinese,too...

Control Panel -->Regional and Language Options:

Regional Tab:

Chinese(PRC)

China

Advanced:

Chinese(PRC)

Finally,Installing a IME , such as freewb,and so on,or add Microsoft PinYin IME...
