How to replace the z sensor batteries

Replacing z sensor batteries

1. To replace batteries in the z sensor, locate the panel and 4 screws on the front of the device. The yellow sticker remains adhered to the panel, but you may remove this panel when replacing batteries.

2. Using a Phillips head screwdriver or drill, unscrew all 4 screws and set them aside.

3. Remove the white plastic panel. The yellow sticker should remain on the panel during the battery replacement. 

4. Replace the z sensor's batteries (2 AA Energizer Lithium).

5. Replace the white panel and gently secure the screws back in. Screwing them in too tightly may crack the panel and compromise the device.

6. Press the power button one time to turn the device back on.

4. Carefully run the coin along the seam and pull up until the device splits into two.

5. Replace the screen's batteries (4 AAA Energizer Lithium) and snap the two pieces of the device back together.
