My OH1 won't start, what can I do?

Applies to: OH1+

If your OH1 won't turn on, it's probably because the battery is empty.

To charge your OH1:

  1. Place the sensor into the USB adapter with the lens facing up so that the contacts on the sensor and USB adapter meet.
  2. Plug the USB adapter into a computer USB port.

You'll know the battery is charging when the yellow LED blinks slowly. Note that it may take a while for LED to start blinking if the battery is completely empty.
