FIRMWARE UPGRADES
From time to time, COBY may release fiirmware updates to improve the perfor- mance of the MP-C841 or to add additional features. Please check the COBY web- site periodically at www.cobyusa.com to see if new fiirmware has been released for your player. If you are experiencing abnormal behavior with your player, you may choose to restore (format) your player before updating its fiirmware.
1.Download the latest fiirmware for your player from www.cobyusa.com. Save this fiile to the computer.
2.Connect your player to the computer. Double-click the Removable Icon that corresponds to your player, and then double-click the FIRMWARE folder to open it.
3.Double-click the downloaded fiirmware fiile (you may need a fiile compression utility installed on your computer). In the window that appears, select the fiile that ends with “.BIN” and copy it to your player’s root directory.
4.Disconnect your player from the computer.
5.Press and hold 
to turn the player on. The player will update its fiirmware automatically.
Always use a new battery before attempting to upgrade the firmware. Do not interrupt the fiirmware upgrade —doing so could damage your player and render it inoperable.
