instructions for the proper handling, storage, and disposal of batteries. Do not store the PRODUCT with

batteries installed.

BATTERY HAZARD WARNING

Battery manufacturers warn against mixing new and used batteries or different brand batteries
together as this may increase the risk of leakage, fire or explosion. Do not, puncture, short-circuit,
disassemble or heat batteries above 212°F (100°C). Do not recharge the batteries unless they are
specifically designed as rechargeable batteries and then only in accordance with manufacturer’s
directions.
Lithium Batteries: Industry wide there have been reported incidents of off-brand Lithium
batteries exploding or catching fire creating serious consequences. SIGTac includes batteries from
Duracell® and other well-known battery manufacturers with its products, and strongly urges you to
only purchase replacement batteries from Duracell®, or other well-known battery manufacturers like
Panasonic® and Rayovac®. These batteries are designed for use in high performance, high-drain
devices, and their designs incorporate fault and heat protection for added safety. Use of inferior
batteries may cause an explosion or fire, creating risk of damage to your device that will void the
SIGTac warranty, cause damage to other property, and potentially serious injury or death.
