Remove conductive articles such as watches, bracelets, and rings.
● Do not use a metal to simultaneously touch two or more battery terminals or
simultaneously touch a battery terminal and a grounded object (such as the
battery compartment). Otherwise, short circuits will occur, causing sparks or
explosion.
