the scale will damage the internal sensor; so you must avoid actions such as shaking or
dropping the scale. This is a sensitive piece of electronic equipment and will be affected
by things such as moisture, extreme temperature changes, magnetic fields, careless
handling and misuse.

The scale will automatically shut-off after 60 seconds of inactivity this is to help conserve
the battery power. We recommend good quality AAA batteries.
