- When the batteries run out, or if the product is not to be
used for a long time, remove the batteries from the
product.
- Do not attempt to recharge batteries that are not
designed to be charged.
• If the batteries do leak, avoid contact with the leaked fluid.
If the battery fluid should come in contact with your eyes,
mouth, or skin, wash immediately with water and consult a
doctor. Battery fluid is corrosive and may possibly cause
loss of sight or chemical burns.
• When using rechargeable batteries, follow the instructions
that came with the batteries. Use only the specified charger
device and within the specified charging temperature
range when charging.
Charging with an unspecified charger or at a temperature
outside the range may cause leakage, overheating,
explosion, or malfunction.
• Keep batteries away from children. A child could
accidentally swallow a battery. Failure to observe this may
also cause inflammation due to battery fluid leaks.
• Do not put batteries in a pocket or bag, or carry or store
them together with pieces of metal. Batteries kept in such
condition could short, burst, or leak, causing a fire or injury.
