Handling precautions [Handling precautions]
    • Use only the genuine RICOH lithium-ion rechargeable batteries, DB-90, which our company supplies. There is the risk of explosion if the battery is replaced by an incorrect type.
    • Do not use the specialized electrical power cord with other products.
    • Do not subject the appliance to strong shock.
    • Do not use in a place which is extremely hot or cold or a place subject to strong vibrations.
    • Do not use in a place which receives direct sunlight and could reach high temperatures.
    • When you have finished charging the batteries, pull out the plug from the outlet. If you leave the plug in the household electrical outlet, it can cause fire.
