[* blackicon_caution] '''If the screw is not turning avoid forcing it. '''Using the #00 screwdriver, unscrew the six, 6mm screws from the back cover of your calculator.
[* redicon_note] Place the six screws somewhere safe. They are small and can easily get lost. You will need them later.
[* black] Use your hand or the spudger to pry off the back cover.
