1.) Put the monitor back on its charger to reset the monitor and charge it --> Band flashing Red, charge for 2 hrs until it no longer flashes Red.
2.) Try resetting the bluetooth --> swipe down on your tablet home screen and click the bluetooth button off and then back on (so that it is lit up yellow)
3.) Is the band on right? --> the band should be worn on the non-playing arm with lights DIRECTLY AGAINST THE SKIN.
...Still not working...?
1.) Try turning the band off and back on
2.) Double check that the protection sticker that covers the sensors has been removed
