● Low Temperature Precautions
• Your digital camera requires large amounts of current for
proper operation. The amount of operation provided by its
lithium ion rechargeable batteries is greatly reduced by use
at temperatures that are colder than 25
°
C. The following
steps are recommended when using the camera under low
temperatures (below 10
°
C).
• Keep the battery, with its cap in place, inside your pocket
and load it in the camera until just before you plan to use
it. Keep the battery away from direct contact with pocket
heaters or other sources of heat.
• Turn off the monitor screen and use the optical viewfinder
to compose images.
• Prepare extra sets of charged lithium batteries for re-
placement.
• Use the AC adapter to power the camera.
• Use a CompactFlash card to store images instead of a
microdrive.
Intermittent Operation
• Intermittent operation dramatically reduces battery ca-
pacity. You can expect about one hour of operation
(about 55 images) under room temperature (25
°
C)
when repeating a cycle during which you spend 10
minutes recording one image per minute (with flash),
followed by one minute of playback, and then nine
minutes of power off.
• The same sequence as described above results in
about 12 minutes of operation (about 11 images)
when performed at 0
°
C.
Low Battery Indicator
The following shows how the battery capacity indicator on
the monitor screen and the indicator display changes as bat-
tery power is used. Replace all four batteries as soon as pos-
sible after they go dead. If you continue to use the camera
while the battery level is
or , camera power will au-
tomatically turn off.
