Cause/Remedy
• The rechargeable battery has been inserted incorrectly or the AC
power adaptor has been connected incorrectly.
, Insert the rechargeable battery correctly or connect the AC
power adaptor correctly.
• Because of the battery's characteristics, the capacity of the
rechargeable battery may be smaller than normal when it is used for
the first time or after a long period of disuse.
, Charge and discharge the battery several times. The normal
battery life will be restored.
• The rechargeable battery is drained (nothing appears in the display
window).
, Charge the rechargeable battery. It takes one minute after placing
the recorder on the battery charging stand for an indication to
appear and charging to start. If charging does not start even after
a minute, replace the recorder on the battery charging stand
again.
• The surrounding temperature is too high or too low ("CHARGE
5 C–35 C 41F–95F" appears in the display).
, Charge the battery at a temperature of +5 C (+41 F) to +35 C
(+95 F).
• The quick mode was set to "Quick On".
, If you set the quick mode to "Quick On", the power stays on
inside recorder even when there is no operation, causing the
rechargeable battery life to shorten (page 69). If the rechargeable
battery is not fully charged, the battery may become drained
after a while. If this happens, charge the rechargeable battery
again (page 17).
• The useful life of the rechargeable battery may be ending.
, Replace the rechargeable battery with the new one.
• This is normal and poses no danger.
