Avoid Contact with Refrigerant
STATIC DISCHARGE: Climates in some parts of the world are conducive to creating static electric build up (ESD). Your
scale has been designed to eliminate the damaging effects of ESD. In some extreme cases, ESD will be apparent on your
scale by a lack of response or an inability to turn off the unit. In the rare case that this occurs, simply disconnect the
battery, wait 1 minute and reconnect the battery. The scale will "reboot" itself and operate normally once the unit is
turned on.
