How to switch to private browse mode

From calculator mode to browse mode

When Calculator-R starts, only calculator is displayed.  To switch to the private browse mode, you need to enter your PIN on the calculator.
However, you cannot open the browser by inputting just the registered password (four digits) into the calculator.

How to enter your PIN

For example, if you have registered the password as 9999, enter “0.9999.” on the calculator mode.  Please note that a decimal point is required at two places before and after the password.  The last decimal point is not displayed even if it is pressed.
