Batteries may leak or burst if they are used incor-
rectly. Please observe the following cautions (p. 
251).

 

1

 

• When inserting batteries, carefully observe the 

correct polarity (“+” and “-”).

 

2

 

• Do not mix new and partially used batteries, or 

batteries of different types.

 

3

 

• If you will not be using the device for an 

extended period of time, remove the batteries.

• If the batteries have leaked, use a soft dry cloth 

to carefully wipe the liquid off the battery 
compartment, and install new batteries. If liquid 
that leaks from a battery contacts your skin, it 
may cause skin irritation. Battery liquid that gets 
into your eye is dangerous; immediately wash 
out your eye with water.

• Do not carry or store batteries together with 

metallic objects such as pens, necklaces, or 
hairpins.
