Notes
• Do not charge any rechargeable battery other than
an NH-14WM (supplied) using this AC power
adaptor.
• If you press  during charging, charging stops
and playback of CD starts.
• If you connect the AC power adaptor to player
during playback, play stops.
• During charging, the player and the rechargeable
battery become hot. This poses no danger.
• Connect the AC power adaptor securely. Make
sure that the OPR lamp on the player lights up.
Unsecure connection interrupts charging or play.
• Take out the rechargeable battery when the player
is not to be used for a long time.
To remove the rechargeable battery

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 in 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.
