I just bought the ntt docomo casio f-02d recently but I find it a bit difficult to handle.
I managed to switch on the wifi but now I do not know how to switch it back off.
I read the manual but it would not say anything.
Can you please help me with that? Because the wifi causes a lot of battery lose.
To turn off wi-fi you need to find the page where you choose connection type (Whether FOMA or wi-fi). Go to tools menu > wi-fi > client mode > common setting > priority connection settings > connection mode setting > choose single mode (FOMA).
Also try this, but I wonder if it will work. Keep holding the camera button for a while. It might open the connection mode setting page directly. If not, just follow the steps above
