• Insert the battery correctly. If the battery is incorrectly oriented,
malfunction may result.
• Do not open the battery cover or remove the battery when the
camera is turned on.
• If you do not intend to use the camera for a long time, remove the
1
battery to avoid the risk of leakage.
• If the camera is left without the battery for a long time, the date and
time may be reset. If this happens, follow the procedure in "Setting
the Date and Time" (p.30).
• Image Storage Capacity, Recording Time and Playback Time
(at 23°C, LCD monitor on with fully charged D-LI7 battery)
Image Storage Capacity
(using the flash for 50% of shots)
Approx. 180 pictures
The still picture storage capacity is based on measuring conditions in
accordance with CIPA standards and the movie recording time and playback
time are based on PENTAX measuring conditions. Some deviation from the
above figures may occur in actual use depending on shooting mode and
shooting conditions.
• In general, battery performance temporarily deteriorates as the
temperature decreases. When using the camera in a cold
environment, keep it warm by putting it in your pocket or inside
your coat. Battery performance that has deteriorated due to low
temperature will be restored when the battery is returned to room
temperature.
• Be sure to take a spare battery with you when traveling abroad or
to a cold region, or if you intend to take a lot of pictures.
• Battery Level Indicator
You can check the battery level by the # symbol on the LCD monitor.
