Sony D-NE820LS User Manual

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 the OPR lamp 
goes off and then use the player until 
the battery is completely depleted (“Lo 
Batt” appears on the display).  Repeat this 
procedure several times.
When the battery life is still 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.

When using a dry battery

You can extend the power available by using 
a dry battery, together with a rechargeable 
battery by attaching the external battery case.
Make sure to remove the AC power adaptor 
when attaching the external battery case.
The battery in the player and that in 
the external battery case are discharged 
simultaneously.
When using the rechargeable battery and dry 
battery together to extend power, use a fully 
charged rechargeable battery and new dry 
battery.
