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
pressing x • CANCEL/CHG for an indication to appear and
charging to start. If charging does not start even after a minute,
disconnect the AC power adaptor from the recorder, connect it
again and press x • CANCEL/CHG.
• 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 71). 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 15).
• 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.
