Handling Precautions
• Keepthe battery pack terminals(_C_) dean at all times. Dirty
terminals may cause poor contact between the battery pack and
camera. Polishthe terminals with a tissue or a dry cloth before charging
or usingthe battery pack.
• Do not rapidly overturn or wave the battery charger around when it
contains the battery pack.The battery pack could fly out.
• At low temperatures, battery pack performance may be reduced and the
low battery icon may appear earlierthan usual. Under these conditions,
resuscitatethe battery pack by warming it in a pocket immediately
before use. However,ensurethat there are no metallic items in the
pocket that could causea short circuit, such as a key holdel, etc.
• Do not place anything, such astablecloths, carpets,bedding or cushions,
on top of the batterycharger while it is charging. Heat will build up and
could result in a fire.
• Do not charge batteries other than Battery PackNB-1LHor NB-1L(sold
separately)in this charger.
• The battery pack continues to dischargea minimal portion of its power
while installedin the camera, even with the power off, or in the charger.
This will shorten battery life.
• Do not allow any metal objects suchaskeyringsto touch the "+" and "-"
terminals(Fig. A), asthis can damage the battery pack.Tocarrythe
battery pack or store it during
periods of disuse,always Fig. A _ Fig. B
replacethe terminal cover
(Fig.B)or placeit inthe
supplied caseand storeit in a
cool, dry place. Rechargeit
fully before using it again.
• Evencharged battery packs continue to discharge naturally. You are
advised to charge the battery on the day of use, or one day before,
to ensure a full charge.
• Since storing a fully charged battery pack for long periods of time
(about 1 year) can shorten its life cycle or affect performance, you are
recommended to use the battery pack in the camera until it is
completely discharged and to store it at normal temperature (23_C/
732) or lower. If you do not use the battery pack for long periods of
time, charge it fully and discharge it fully in the camera at least once
a year before returning it to storage.
• If the performance of the batterypack diminishessubstantially even when
it is fullycharged, its life has beenexceededand it should be replaced.
