PRECAUTIONS
Lithium Batterywarning notice; Please revise as follows:

Safety Instructions for Lithium Batteries.

Lithium batteries contain inflammable materials such as
lithium, organic solvent and other chemical. Incorrect
handling of lithium batteries may result in HEAT GEN-
ERATION, EXPLOSION or FIRE which may lead to per-
sonal injuries. To prevent accidents, strict observance of
the following precautions is essential.

1. Do not stack the batteries.
When the positive and minus terminals of the batter-
ies touch each other or other metal surfaces, large
currents will flow resulting in heat generation, explo-
sions or fire. To prevent short circuits. be sure to use
the correct packing material for storage and ship-
ment. Should a fire occur, do not use water to extin-
guish. Chemical reaction between lithium and water
may accelerate the chemical reaction andthefi re. Use
dry sand for extinguishing the fire.

2. Do not dispose the batteries in fire.
Disposing batteries in fire, is verydangerous because
an explosion or violent flames will occur.

3. Do not heat the batteries or solder directly to the
batteries.

These specifications are service target specs.

Specifications and components are subject to change without notice.
Overall periormance will be maintained or improved.

When heat in excess of 100 rC (212 Fl is applied, the
resin at the sealing sections, separator and other
areas becomes damaged.

Internal short circuits or leakage of electrolyte may
cause explosion or fire.

4. Do not recharge the batteries.

Recharging may result in gas generation inside the
battery and cause swelling, explosion or fire.

5. Do not disassemble the batteries.
internal gas is irritating to the throat. Exposed lithium
may generate heat and fire.

6. Do not apply pressure to or deform the batteries.
When pressure is applied to the batteries, electrolyte
may leak or internal short circuit may occur. As result
there can be heat generation, leading to explosion or
fire.

7. Do not mix different types of batteries.

Mixing different types of batteries or new with old
batteries can cause some batteries to overcharge,
resulting in swelling or explosion.

8. Observe proper polarity.
improper assembly of the batteries into the product
may result in shortvcircuit conditions causing heat
generation, explosion or fire.
