All the Philips KEY cameras support USB Mass Storage Class. When you first connect the camera to a PC running on Windows ME, 2000 or XP via the USB connector, an application will launch to recognize the camera as a USB Mass Storage Class Device. Your camera is detected as “New Hardware” and will be listed automatically as a “Removable Disk” in Windows Explorer, so there is no need for you to actually install a separate driver. For MAC OS9-X users, once the camera is connected via the USB on your computer, the camera is detected and shown as a disk drive icon named KEYRING xxx on your desktop (xxx is the model number). Important: For PCs running on Windows 98 SE, a separate driver has to be installed before hooking up the camera with your PC. Please install your driver by following the steps below: 1. Insert the installation CD into the CD-ROM drive. 2. An application will run automatically in the background checking whether a driver has been previously installed on your computer. Driver installation for your camera will start automatically if no previous driver is detected. (If the application fails to launch automatically, try opening and closing the CD-ROM tray to kick-start the application.) 3. Once the driver is installed, you can hook up the camera to your computer for downloading of JPEG files via Windows Explorer or Photo Manager.
