Try taking out ALL batteries (including the little round one) and leave them out one whole night.

On the back of the calculator, there is a little "reset" hole. Use a pen and press it into that hole for a few seconds, then release. You should now be able to turn on your calculator as if it was brand new from factory without the "p".

Hello,

It may be due to the angle unit used. You can have angles in degrees, in radians, and in grads. You should set the default angle unit to waht you problem calls for.

To set degree as default SHIFT MODE 3

To set radians as default SHIFT MODE 4

To set grads as default SHIFT MODE 5

The values of angles calculated by the inverse trigonometric functions are in the default unit that is set . This may be the source of the wrong answers that you get.

Hope it helps.
