Once you receive your OMbra, charging your OMbox for 20 minutes should do the trick for a quick run, and a full charge should take no more than 2 hours.
To charge your OMbox, make sure you use the micro USB charging cable provided by OMsignal in a laptop or iPhone wall charger.
Once your OMbox is paired to OMrun, you can check battery life by tapping on the box icon in the top righthand corner of the screen. If it doesn’t connect, the box might be in sleep mode. Double tap it or plug it into the charger to wake it up.
