3. Potentially explosive atmosphere
Turn off your electronic device when in any area with a potentially
explosive atmosphere. It is rare, but your electronic device could
generate sparks. Sparks in such areas could cause an explosion or fire
resulting in bodily injury or even death. Areas with a potentially explosive
atmosphere are often, but not always, clearly marked.
4. Battery information
A rechargeable battery has a long service life if treated properly. A new
battery or one that has not been used for a long period of time could have
reduced capacity the first few times it is used. Do not expose the battery
to extreme temperatures, never above +50° or below -10°. For maximum
battery capacity, use the battery in room temperature. If the battery
is used in low temperatures, the battery capacity will be reduced. The
battery can only be charged in temperatures between 0° and +45°.
