Usage cautions and notes
●
Do not peel off or scratch the battery covering.
• Do not use commercially available batteries that are entirely or partly uncovered. Do
not use batteries with flat poles. Using such batteries may cause leakage, heat
generation or explosion.
●
Take spare batteries when going out.
• Be aware that the recording time is reduced in low temperature conditions such as
at a ski slope. Battery performance deteriorates when the ambient temperature is
low (10 °C or less) and the recording/playback time may become extremely short. In
particular, when using alkaline batteries, warm them in your pocket etc. before using
them. Make sure that pocket heaters or metal objects such as lighters do not come
into contact with the batteries when warming them in your pocket etc. The battery
performance will recover when the temperature returns to normal.
• Battery performance may vary greatly depending on the brand used, the storage life
from the date of manufacture, and the storage conditions of the batteries.
• Depending on the temperature and the conditions of use, the camera may not
operate properly or the batteries may run out (the remaining battery power may not
be accurately displayed). This is not a malfunction.
• Expended batteries may temporarily recover some performance if they are left for
a period of time. However, they cannot be used for an extended period. Be sure to
replace them with new batteries.
Rechargeable Ni-MH batteries
●
You can use Ni-MH batteries after charging them with a dedicated battery charger.
However, improper handling of the batteries may cause leakage, heat generation, fire
or an explosion. Observe the following.
• If there is dirt on the battery poles, you may not be able to charge the batteries
normally. Carefully clean the battery poles and battery charger terminals with a soft
dry cloth.
• Do not peel off or scratch the covering on Ni-MH batteries.
• When the batteries are used for the first time, or after having not been used for a long
period of time, they may not fully charge. This is a characteristic of Ni-MH batteries
and is not a malfunction. Battery performance will return to normal after a few
charges and discharges.
• We recommend charging the batteries after they are fully discharged. If you repeat
charging before they are fully discharged, battery performance may be reduced. (This
is called “memory effect.”)
If a “memory effect” occurs, continue using the batteries until the camera can no
longer perform recording or playback and then charge them fully. Battery performance
will be restored after a few charges and discharges.
• Once the Ni-MH batteries have reached full charge, do not continue to charge them.
• Over time, Ni-MH batteries naturally discharge and their performance lowers even if
they are not used. If the batteries are left in the camera in this condition, they will be
drained excessively and may become unusable even if they are charged again.
• When storing the batteries for a long period of time, we recommend charging them
once a year. Remove the batteries from the camera and store them again after they
have been completely expended.
