The Pearl contains a switch inside that puts the unit to sleep when a magnet is in proximity. I've been trying to find the location of this switch for several days with no success.
I'm including a high-resolution image of the rear side of the Pearl. If the switch is on the front side, please let me know and I'll post a front image.
If you know where the elusive switch is, please post a marked copy of the image. Thanks in advance!
Most browsers will shrink the image to fit the window, you may need to zoom.
