15 Getting Started
4. Charge the Battery
You can charge a battery in the camera (explained here) or
in the extra battery bay of the camera dock or in the
HP Photosmart quick recharger (see Purchasing Camera
Accessories on page 175).
1. Plug the power cord into the HP AC power adapter. If
more than one power cord is in the box, use the cord that
is appropriate for power outlets in your country or region.
Plug the other end of the power cord into an electrical
outlet.
2. Attach the thin cord from the
HP AC power adapter to the
cradle as shown.
3. Place the camera in the
cradle. The Power light on the
back of the camera starts
blinking to show that the
battery is charging.
When the Power light stops blinking, the battery is fully
charged. Recharging usually takes 4-6 hours in the camera.
You can continue using the camera while the battery is
recharging.
NOTE: The camera may get warm while the battery is
charging, as well as after prolonged use under battery
power. This is normal.
