Important Battery Information
Caution Use and replace only with AA (LR6) Alkaline, Zinc-Carbon, or Zinc-Chloride Batteries.
General Precautions
● Keep batteries out of reach of children.
● Insert the batteries in the proper direction as indicated by the positive (+) and negative (-) markings on
the battery and battery compartment.
● Do not mix old and new batteries or batteries of different types (for example, carbon and alkaline
batteries).
● Always remove old, weak, or worn-out batteries promptly and recycle or dispose of them in accordance
with Local and National Disposal Regulations.
● If a battery leaks, remove all batteries and recycle or dispose of them in accordance with the battery
manufacturer’s instructions and Local and National Disposal Regulations. Before inserting new
batteries, thoroughly clean the battery compartment with a damp paper towel, or follow the battery
manufacturer’s recommendations for cleanup. If fluid from the battery comes into contact with skin or
clothes, flush skin with water immediately.
● Remove the batteries if your device is to be stored for an extended period of time without being used.
Special Precautions
The precautions below are to prevent the sudden release of electrolytes, which these prohibited actions can cause:
● Do not install the batteries incorrectly. Carefully observe the positive (+) and negative (-) markings on
the battery for proper installation.
● Do not open, puncture, or mutilate the batteries.
● Do not heat batteries.
● Do not use a fire to dispose of batteries.
Released battery electrolyte is corrosive, can cause damage to the eyes and skin, and may be toxic if swallowed
