Using Your Digital Camera, Charging the battery

3 Using Your Digital Camera

Charging the battery

Long battery life is one of the key benefits of this camera compared to other digital cameras. On a full charge, the camera will capture hundreds of images. Your camera battery has already been charged prior to shipment. So, you should be able to take pictures without recharging it. However, just to be safe, you may want to follow the instructions below to make sure that your camera is fully charged before leaving home

The lithium-polymer battery used in the camera recharges automatically when the camera is plugged into a PC via the USB cable. In order to charge the battery the first time, first install the included software (see Installing the Software in section 4) and then plug the camera into your computer using the provided USB cable. When the battery is charging, the green LED will blink. When charging is complete, the green LED will be steady on.

Lithium-polymer battery tips:

oSafety note: Always observe the precautions described in Section 8. o It takes approximately 3 hours to fully charge a depleted battery.

o The camera can be charged at ambient temperatures between 0°C (32°F) and +40°C (104°F).

o The battery does not need to be fully discharged or exhausted before being recharged.

o Lithium-polymer batteries lose their charge even when not used. So, be sure to charge the battery before taking pictures.

o To ensure that your battery lasts as long as possible, switch the camera off when you are not using it.

o The number of available shots will be lower at low temperatures. You can increase the amount of power produced by putting the camera in your pocket or another warm place to heat it just before taking pictures. If you are using a heating pad, take care not to place the camera directly against the pad.
