Introduction

If your back case is cracked or broken this guide will show you how it is removed and replaced.

    • Remove the battery cover.

    • Remove the AAA batteries from the calculator.

  2. UusD1DCUSQ1FZSQP
    • Remove the 5mm Philips #00 screw holding backup battery cover.

    • Remove the backup battery cover.

    • Use plastic opening tool to remove the backup battery. Place the tool in the small cut-out next to the battery and pry the battery out.

    • Be careful, the backup battery is spring loaded and may shoot up when you remove it.

    Can confirm. The battery has a tendency to launch itself out of the bay!

    • Unscrew the six 7.5mm T6 screws on the back case. You will need to use a screwdriver with a long and skinny head.

    • Pry back case off. Insert the plastic opening tool in the track for the protective cover and pry the halves of the case apart.

    I had to apply quite a bit of pressure to split the halves. I almost thought the sides would break, but they didn't.

    I'm sure this is assumed, but this guide also worked on the Silver Edition of the 83-Plus -- just in case anyone was curious.
