15 First Steps : Putting Batteries in Your Camera
First Steps
This section guides you through the steps you will take when using your
COOLPIX 300 for the first time, from inserting the batteries or plugging in
the optional AC adaptor to making your first photographs, memos, and
recordings.
Putting Batteries in Your Camera
When putting new batteries in your camera, first make sure that the camera
is off (if you are using the optional AC adaptor, you should also unplug the
camera). You may then slide the battery cover off as illustrated below.
Insert the batteries with the positive (+) and negative (-) poles aligned as
shown in the illustration on the following page. Use only AA alkaline
batteries and be sure that all batteries are of the same model; do not mix
batteries of different types or use new batteries together with old. Avoid
using old batteries, as this may prevent the battery-level indicator from
functioning properly.
