All you need to know to start using Shell
Inside the box, there are two Keycards and one Keycard Shell. Make sure the security sticker at the opening is intact to ensure the devices are not tampered with.
a. Open back cover
Gently press the back cover and slide it downward to remove.
b. Insert battery
Insert the battery into the slot. Slide the back cover upward to close.
c. Insert Keycard
Insert the Keycard with the chip facing up and push it in all the way. The Shell powers on automatically.
If the screen stays off, charge the Shell with a USB-C cable and try again later. Check out FAQ for more tips.
