1 Brief Description

Your digital camera with color LCD display is roughly the size of a credit card - only 13 mm thick. The camera’s portability and convenience are enabled by its “worry free” rechargeable battery, simple user interface, and easy image download when you connect the camera to a PC with the supplied USB cable.

Package Contents

Be sure to check that the package contains all the items listed below:

Camera

USB cable

User Manual

CD-ROM

Wrist Strap

Pouch

If any items are missing, please contact the store where you purchased the camera. Keep the camera packaging in a safe place as it will be needed if you return the camera for repairs, etc.

2 Before Using Your Camera

To ensure that you use your camera correctly, read the Safety Notes in section 8 and the rest of this user’s manual carefully.

Holding the camera correctly

Due to the extremely compact size and light weight of the camera, it is critical that you hold the camera securely in order to avoid “camera shake”. The camera is particularly sensitive to “shake” in low light environments. Taking a picture in low light requires a longer exposure time for the image to be captured and any movement during this time might cause a blurred image.

When taking a photo in low light the flash may trigger. Before this happens, try to avoid gripping the camera with your fingers placed on the front face of the camera. Instead, hold the camera on its edges so that the light of the flash does not reflect off your finger(s) and cause lens flare.

Test photos

Before you capture your first images, we recommend you take some test photos to make sure that the camera is working properly. This will also help you become comfortable holding the camera in order to capture satisfactory images.
