Power Supply

- AAA Batteries: For backup power or when a USB power source is unavailable, insert 2 AAA batteries (included) into the battery compartment on the underside of the scale. Ensure the batteries are inserted with the correct polarity (+/-). If not in use for an extended period, remove the AAA batteries to prevent leakage.
