To turn on the Mevo Boost, press and hold the button on the back of the unit under the outer ring lock until the white LEDs start rotating on and off from left to right.
You will know that it's on when the LEDs stay solid for a moment and the LED ring by the Mevo's battery indicator lights up, showing that it is charging.
To power on your Mevo camera, simply press and hold the power button on the top of the camera for a moment. You will hear a pair of pings and the LED ring will show a white light rotating clockwise, after which you can remove your finger.
After a moment, the Mevo will complete its startup; you should see a pulsing blue LED over the Wi-Fi indicator on the back of the Mevo.
