Just like the previous CN X models, it can display Chinese and English, so the following photos will present as a English interface.
But let's look at the front panel first, you would find it's very different from the CW series in other counties, all the keys own a SHIFT function, and are translated to Chinese, including the FORMAT key. Also the x key is not own a QR as SHIFT function, it means CN CW series do not own a QR function, and actually the ClassPad.net is not reachable in China yet.
Let's do a compare with the fx-880BTG, a product from Vietnam:
You should see the differences between the two, and you would also find no Math Box mode on 999CN CW. And when I press SETTINGS key on HOME screen, it would display a Calculator ID screen, also no QR on the left, and the items in SETTINGS menu are only three, the Get Started option is missing.
(Now you know it's a EY028 model.)
So many new things for CW series are missing! However, one thing is still remained on the CN CW series, which is the Multi-Statement colon character and the variable store character. It is hidden in the CATALOG screen:
In addition, it owns the Verify and Simplify function.
For other functions are almost same with the globle model 991CW. So anything else you want to know about the functions? You can make a comment.
When I try to remove the battery and use solar power only, it displays a icon that indicated the battery is dead.
Here are the back panel and the insider PCB things, you would find it's made in China, not Thailand.
