Olympus VN-180 VN-180 Instructions (English) - Page 23

BATTERY PRECAUTIONS 1 Always use the batteries correctly. Fluid leakage, heat generation or explosion may occur if the batteries are used incorrectly. When the batteries are replaced, be sure the + and - polarity positions are correct. 2 Some batteries are of the same sizes but have different voltages. 3 Note the difference between dry type and rechargeable batteries. Use LR03 or R03 dry type batteries. 4 When there is fluid leakage, carefully wipe off the fluid from the battery compartment and then insert the batteries. 5 Remove the batteries when the unit is not used for more than one month. 6 If a battery is short-circuited, disassembled, charged or thrown into a fire, damage or ignition may occur. 7 Poor contact may occur if + or - polarity symbols are obscured with oil or sweat. Wipe off the batteries with a clean cloth before use. 8 Be sure to bring extra batteries if the unit will be used for long periods of time, i.e. lengthy speeches or lectures. 23
