Formatting the MicroSD Card
“The Memory card formatting is the process of preparing the MicroSD Card for data storage. It cleans the SD Card by removing previously existing files on the card and creating a new file system.
Unlike erasing, formatting improves the overall performance of the SD Card. Due to the constant overwriting cycles with your Acumen Dash Cam, we recommend formatting regularly to extend the lifespan of your MicroSD Card.
If you don’t format the card regularly, a bad block may result in a corrupt file.”

The hardwire kit will automatically detect the battery voltage, and if the voltage is lower than 12V,it will automatically cut off the power supply to protect the battery from running out of power.
