Note on the useful life of the rechargeable 

battery and when to replace it

If the battery is new or has not been used for a 
long time, it may not charge completely. 
In that case, charge it until “Charging” 
disappears from the display and then use the 
player until the battery is completely depleted 
(“Low Battery” appears on the display).  
Repeat this procedure several times.
If the battery life is shorter by about half of 
a normal charge after trying this procedure, 
replace the battery with a new rechargeable 
battery.

Note on carrying the rechargeable battery

Use the supplied battery carrying case to 
protect against unexpected heat.  If the 
rechargeable battery comes into contact with 
the metallic objects, heat or fire may occur 
due to a short circuit.

Checking the remaining 

power of the battery

The remaining power of the battery is 
indicated in the display as shown below.  As 
the black indicator section decreases, the 
remaining power is depleted further.

Notes on rechargeable batteries and dry 

batteries

•  Do not charge dry batteries.
•  Do not throw the batteries into a fire.
•  Do not carry batteries in a pocket, etc. with coins 

or other metallic objects.  The battery can generate 
heat if its positive and negative terminals are 
accidentally allowed to come into contact with a 
metallic object.

•  Do not mix rechargeable batteries with dry 

batteries.

•  Do not mix new batteries with old ones.
•  Do not use different types of batteries together.
•  When the batteries are not to be used for a long 

time, remove them.

•  If battery leakage occurs, wipe off any deposit 

left in the battery compartment, and install new 
batteries.  If the deposit adheres to your skin, wash 
it off thoroughly.
