3Information concerning the (optional) Li-ion battery pack:The battery pack includes flammable objects such as organic solvent.Mishandling may cause the battery to rupture producing flames orextreme heat, deteriorate, or cause other forms of damage to thebattery. Please observe the following prohibitive matters.• Do not disassemble or reconstruct battery!The battery pack has a safety function and protection circuit toavoid danger. If they suffer serious damage, the battery maygenerate heat or smoke, rupture, or burst into flame.• Do not short-circuit the battery!Do not join the + and – terminals using any form of metal (suchas a paper clip or wire). Do not carry or store the battery pack incontainers holding metal objects (such as wires, chain-necklaceor hairpins). If the battery pack is short-circuited, excessivecurrent will flow and the battery may generate heat or smoke,rupture, or burst into flame. It will also cause metal objects toheat up.• Do not incinerate or apply heat to the battery!If the insulator is melted, the gas release vent or safety functionis damaged, or the electrolyte is ignited, the battery maygenerate heat or smoke, rupture, or burst into flame.• Do not use or leave the battery near fires, stoves, or otherheat generators (areas reaching over 80°C)!If the polymer separator is melted due to high temperature,an internal short-circuit may occur in the individual cells andthe battery may generate heat or smoke, rupture, or burst intoflame.• Do not immerse the battery in water or get it wet by othermeans!If the battery’s protection circuit is damaged, the batterymay charge at extreme current (or voltage) and an abnormalchemical reaction may occur. The battery may generate heat orsmoke, rupture, or burst into flame.DANGER
