Battery Insertion and Removal

DON'T INSERT THE BATTERY UPSIDE DOWN!!! There is a printout on the white face of the battery stating that "this side is down". So you should see the blue face when inserting the battery.

Don't force under any circunstance!

Insert the battery in the device. Make sure the white side faces the bottom of the device. Make also sure that you insert the blue handle in the device. Push until you hear a click. The battery is then secure.

To remove the battery, push on the battery in the device. The spring/clip will release the battery and the battery will eject.

Attach to the blue L-attachment, the side of the band that has only one hole.

Tip: Leave the band attached to the L-attachment in the ball enclosure.

To unscrew the device, you don't need to force but you need to snap and rotate the device in the counter-clokwise direction. See this video:
