MicroSD Card Slot Cover
You must use the microSD card slot cover to protect the microSD card in hazardous locations.
Do not remove a microSD card while the SD IN USE LED is flashing or solid because file
corruption may result.
Note Screw the slot cover closed completely. Tighten the captive screws to a
maximum torque of 0.75 N · m (6.7 lb · in.) using a #1 Phillips screwdriver. Do not
overtighten.
