Resizing the Battery Compartment.
To resolve internal battery issues, follow these steps:
- Use a Phillips head screwdriver to loosen the three screws on the bottom side of the device (next to the battery) by half a turn.
- Lightly tap the device on your palm to allow the battery to fall out.
- When replacing the batteries, make sure to tighten the screws back by about 75%.
Possible reasons for this issue:
- AA batteries vary in thickness and length, which can cause rattling inside the device. We have designed a somewhat restricted space to minimize this problem.
