Notes
• The supplied battery charging stand can be
used only with this recorder. Any other
models cannot be charged.
• Do not use the recorder to charge any other
battery besides the supplied one or the one
designated for it (NH-14WM(A)).
• Though the battery charging stand and the
battery may become hot during the charging
procedure, this poses no danger.
• Be sure to use the supplied AC power adaptor.
• When a rechargeable battery is charged for the
first time or charged after a long period of
disuse, battery life may be shorter than usual.
Repeat discharging and recharging a few

• When the battery life of a fully charged
rechargeable battery becomes about half the
normal life, replace it.
• Make sure to remove the recorder from the
battery charging stand and disconnect the AC
power adaptor from the wall outlet as soon as
charging is complete. Keeping it connected to
the power source for a long time may reduce
the operating efficiency of the battery.
• Please note the following points when
charging the battery directly with the supplied
AC power adaptor.
—If you press x/CHG immediately after
charging has completed, charging will
begin again. If this happens, press x/CHG
again to stop the charging operation since
the battery is already fully charged.
—Charging stops when you try to operate the
recorder during charging.
• If you remove the recorder from the battery
charging stand for more than 3 or 4 seconds
while it is charging, and then return it to the
stand, the CHARGE lamp will not go off until
approximately 6 hours later, no matter how
many hours the recorder had been on the stand
till then. Please note, however, that the
recorder will become full charged when the
total time on the stand (the time up until you
removed it and the time after you returned it to
the stand) reaches approximately 6 hours,
even if the CHARGE lamp does not go off.
