Appendix
z This charger can be used only to charge
Canon AA-size NiMH batteries NB-2AH.
Please do not attempt to charge NB-2AH
batteries in any other type of charger.
z Never mix new batteries together with
batteries that have been used in other
devices.
z When recharging batteries from the
camera, always recharge both of them
at the same time.
z Do not mix batteries with different
purchase dates or different charge
states.
z Do not attempt to recharge fully charged
batteries, as doing so may reduce or
impair battery performance. Also, do not
charge batteries for more than 24
consecutive hours.
z Do not recharge batteries in enclosed
areas that tend to retain heat.
z Repeatedly recharging batteries before
they become fully depleted may cause
batteries to lose capacity. Do not
recharge the batteries until the LCD
monitor displays the "Change the
batteries" message.
z Wipe the battery terminals well with a
dry cloth in the following situations, as
the terminals may be soiled with oil from
one's skin or other dirt:
-If the battery usage time has
considerably diminished.
-If the number of recordable images has
considerably diminished.
-When charging the batteries (insert and
remove the batteries two or three times
before charging)
-When charging completes in a matter of
a few minutes (the battery charger
indicator remains lit)
z You may not be able to fully charge the
batteries due to their specifications right
after purchase or after long periods of
non-use. If this happens, use the
batteries until their charge is depleted
before charging them again. After doing
this several times, battery performance
will be restored.
