If you're seeing strange artifacts on your RepOne Sensor screen, including erroneous pixels during startup, lines of pixels, a screen full of white fuzz, or upside-down text, don't be alarmed! Your device is just low on battery, it's not broken.


  1. Make sure to use the included cable when charging. Many phone and computer chargers from big brands don't like to power the RepOne sensor. USB ports on computers or other smart devices can be picky as well. A regular 5v wall adapter works well.
  2. Update your firmware. Newer firmware versions have a battery gauge and will alert you when the battery is dead rather than displaying screen artifacts.
