Checking the battery level of a Casio Graph 35+ calculator

Hello,

I own a Casio Graph 35+ (USB) calculator and I wanted to know if it is possible to check the battery level of my calculator?
At the beginning of the year, my calculator would say "low battery," but now it doesn't say anything despite not having changed the batteries..

Thank you in advance!

Configuration: iPhone / Safari 7.0

    Hello,
    There is a key combination that switches the calculator to "test" mode, I will see if I can find that.

      Can't find that on the internet...
      For my 35+ non usb, it's "F6" + "a+b/c" + "ON" and to return to normal mode it's "0" then "F6".
      For the 35+ usb, I can't remember the combination...

      For the Casio Raph 35+/75/85/95 SD or exam, it's
      OPTN + EXP(x10 next to exe) + ON
      Then F1 then 9
