BATTERY CAUTIONARY INSTRUCTIONS

BATTERIES: CAUTION

vUse only 1.5 volt, AA-size batteries, (15A) carbon-zinc or alkaline batteries. (batteries not included.)

vDo not dispose of the batteries in a fire. The cells may explode. Check with local codes for possible special disposal instructions.

vDo not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.

vExercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.

vDo not attempt to recharge the batteries identified for use with this product. The batteries may leak corrosive electrolyte or explode.

vDo not attempt to rejuvenate the batteries identified for use with this product by heating them. Sud- den release of the battery electrolyte may occur causing burns or irritation to eyes or skin.

vWhen replacing batteries, all batteries should be replaced at the same time. Mixing fresh and dis- charged batteries could increase internal cell pressure and rupture the discharged batteries.

vWhen inserting batteries into this product, the proper polarity or direction must be observed. Re- verse insertion of batteries can cause charging, and that may result in leakage or explosion.

vRemove the batteries from this product if the product will not be used for a long period of time (several months or more) since during this time the battery could leak in the product.

vDiscard “dead” batteries as soon as possible since “dead” batteries are more likely to leak in a prod- uct.

vDo not store this product, or the batteries identified for use with this product, in high temperature areas. Batteries that are stored in a freezer or refrigerator for the purpose of extending shelf life should be protected from condensation during storage and defrosting. Batteries should be stabilized at room temperature prior to use after cold storage.
