Notice on Using the Battery
❏
When the AC adapter is not connected and the scanner is connected by USB 2.0 or Wi-Fi to the computer, the
scanner runs on the battery. If the battery becomes runs out and the battery light turns off, you cannot scan. We
recommend connecting the AC adapter to the scanner when the battery lamp starts flashing.

When the scanner is run on USB 3.0 bus power, the scanning speed may become slower when the battery is
running low and the battery light starts flashing fast.
