IMPORTANT Information
Warning! – Substitution of Components May Impair Intrinsic Safety
Warning! – To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing.
Warning! – To reduce risk of ignition of a flammable or explosive atmosphere, batteries must be changed only in a location
known to be non-hazardous.
Warning!
– To reduce the risk of explosion, do not mix old batteries with used batteries, or mix batteries from different
manufacturers.
Caution! – Replace batteries only with two of each (3V total):
1. Duracell MN1500 LR6 1.5 volt AA alkaline batteries
2. Energizer 2012 L91 1.5volt AA lithium batteries
3. Novacell AM3 LR6 1.5V AA Alkaline Batteries.
The following additional precautions should be observed:
1. Use only the type and size batteries specified in the user manual.
2. Do not dispose of the batteries in fire. They may explode. Check with local codes for possible special disposal instructions.
3. Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes, skin. It may be
toxic if swallowed.
4. Exercise 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.
5. Do not attempt to recharge the batteries identified for use with this product. The batteries may leak corrosive electrolyte or
explode.
6. Do not attempt to rejuvenate the batteries identified for use with this product by heating them. Sudden release of the battery
electrolyte may occur causing burns or irritation to eyes or skin.
7. When replacing batteries, all batteries should be replaced at the same time. Mixing fresh and discharged batteries could
increase internal cell pressure and rupture the discharged batteries.
8. When inserting batteries into this product, the proper polarity or direction must be observed. Reverse insertion of the
batteries can cause charging, and that may result in leakage or explosion.
9. Remove 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.
10. Discard “dead” batteries as soon as possible since “dead” batteries are more likely to leak in the product.
11. Do 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.
