To turn off your mounted tablet, hold the power button down until you see a small menu pop up in the top-right corner of the screen. Choose "Power off" to turn off the tablet.
Depending on which model tablet you have your power button could be a red button on the back side of the tablet, or it could be on the front bottom center of the tablet.
You can turn off the tablet and the equipment all at once by simply unplugging the equipment from the wall outlet. Turning the screen off just puts it in sleep mode but doesn't turn your equipment off.
Depending on which equipment you have your equipment could come with a power switch on it. If it does then no need to unplug it from the wall unless you want to. We do recommend that the whole unit be turned off and or unplugged from power when not in use. This is for safety reasons and to prolong the life of the bike.
The tablet will also go to sleep automatically after a set time. To adjust this time, go to the Me tab, select the gear/cog icon in the top right, then select Preferences, then Screen Sleep Timeout.
