Note when using the R-07 on batteries

5

If you handle batteries improperly, you risk explosion and fluid 

leakage. Make sure that you carefully observe all of the items 

related to batteries that are listed in “USING THE UNIT SAFELY” 

and “IMPORTANT NOTES” (leaflet “USING THE UNIT SAFELY).

5

Do not mix fresh batteries with used batteries, and do not mix 

batteries of different types.

5

If you won’t be using the R-07 for an extended period of time, 

we recommend that you remove the batteries to prevent them 

from leaking electrolyte.

5

If electrolyte should leak from the batteries, use a soft cloth 

to wipe the battery compartment clean, and then install new 

batteries. Electrolyte that contacts your skin might cause 

irritation. Electrolyte that enters your eyes is dangerous; if this 

occurs, immediately flush your eyes thoroughly with water.

5

Do not carry or store batteries together with metallic objects 

such as pens, necklaces, or hairpins.

Power conservation function

The power to this unit will be turned off automatically after a 

predetermined amount of time has passed since it was last used

Off function).
If you do not want the power to be turned off automatically, 

disengage the Auto Off function. For details, refer to the “Auto Off” 

(p. 40).
