How do I fix the error message CMOS checksum error defaults loaded?

It has come to our attention that a number of JB-199 players that are 3 years or older have experienced a reset of the BIOS settings. This problem presents in the form of the players inability to boot up and the following message is displayed in a VGA monitor "CMOS checksum error defaults loaded" (you will only see this error in a VGA monitor not in a RCA input monitor). We have identify the cause of the problem to be the BIOS battery running low. To quickly correct this problem (if you are in a show) you will need to connect a PS/2 keyboard and press F1 (please note that a USB keyboard will not allow you to do this) however the problem will come back in the very near future. To permanently correct the problem the BIOS battery has to be replaced. This battery (model CR2032) is widely available at all electronic stores and watch repair centers and it costs around $5 Duracell or Energizer recommended. The battery which is located in the motherboard behind the front panel can be replaced by following this instructions.
