Remove the battery.
Use a thin flat blade screwdriver or knife (use extra caution with the knife) to gently pry the bottom cover open starting at the battery compartment. There are small delicate tabs at the front near the camera. Slowly pry the bottom cover open working toward the camera.
Once opened flip Breeze on its back and look at the rear where the power button is. Underneath the power button you will find a small black circuit with wires leading to the circuit board. Use a toothpick (nonconductive material) to insure the board is in its mounting and doesn’t move around. It is the Compass module.
