2Flip up the battery cover and insert 4 AA batteries, either alkaline or rechargeable nickel metal
hydride (NiMH) .
3Close and slide back the battery cover to the original
position and rotate the lock lever to the “LOCK” position.
1Turn the lock lever to the position “UNLOCK”.
Then, slide the battery cover to the front side of the camera.
Installing batteries
The battery slot is on the bottom side of the camera. Gently turn the camera upside down to install the batteries.
Note
• Make sure to rotate the lock lever to the “LOCK”
position to avoid dropping the batteries.
• Use only nickel metal hydride batteries (NiMH) or
alkaline batteries. Never use manganese batteries or
nickel cadmium batteries.
• Never use batteries of different types or different
manufacturers together or mix old and new batteries.
• Rechargeable nickel metal hydride batteries (NiMH) may be inert and consequently they might not supply
power immediately after purchase or if they are left unused for a longer period of time. Recharge and
discharge the batteries fully about 2-3 times to restore the full function of the batteries.
• Performance time of alkaline batteries might become shorter if they have been left unused for a longer
period of time since their manufacturing date.
• Avoid using batteries in extremely cold environment as low temperatures dramatically reduce the number of
pictures you can take.

●Storagecapacities(numberofpictures)
Approximately 350 shots can be taken with a fully charged rechargeable nickel metal hydride battery
(NiMH; cell capacity 1,900 mAh).
Approximately 250 shots can be taken when using new alkaline batteries (based on in-house test results).
The numbers above are just rough estimates and your results may vary. Extensive operation of the camera
settings or viewing photographs may reduce the number of shots.
●NoteforWi-FiSDmemorycards
Use rechargeable
nickel metal hydride batteries (NiMH ) for the camera when using a Wi-Fi SD memory
card. Alkaline batteries might not be able to supply enough energy to operate the camera properly.
Also, Wi-Fi SD memory cards consume more energy to operate than regular memory cards. The number
of pictures that can be taken and stored are less than the above mentioned number.
●Write-protectiontab
The SD memory card has a write-protection tab. Slide down the
tab to prevent valuable data from being accidentally erased from
the memory card. To save, edit or erase data on a SD memory
card, unlock the card.
●Storagecapacityofmemorycard
The maximum number of photos you can store on the provided 16 GB SDHC memory card is approximately
9,999. After exceeding 5,000 shots, the left message appears on the screen when switching on the camera.
When reaching 9,999 shots, the right message appears and you can no longer take photos with this
memory card with no remaining capacity. Thus, when the rst message appears you should transfer
and back-up the stored data to other storage media and erase the data stored on the SD memory card
in use.
The number of photos you can store on the provided 16 GB SDHC memory card varies depending on the
image size and quality you selected. The following numbers are just an example for your reference.
Photo: 9,680 shots (image quality: Fine, image size: 3M)
Movie: 340 min (maximum time duration for one movie is 10 min)
