In CF-3200/3400 and CF-3200J/3400J models manufactured between 1998 and 1999, a phenomenon has been observed where, if the built-in backup battery (the battery that maintains the calendar function and BIOS) runs out, the BIOS settings switch to an external display, and the main unit's LCD screen stops displaying anything.
The applicable model numbers and serial numbers are listed in the table below. Customers using the applicable product should download the appropriate program from the "Compatible BIOS Change Program" column in the table and change the BIOS. For download and installation instructions, please refer to "CF-3000 Series BIOS Setup Program Installation Method".
Note
Please download the BIOS modification program corresponding to your serial number. Running a different BIOS modification program will prevent your CF-3000 series from booting.
The BIOS update will allow the device to operate normally when powered on. However, because the internal backup battery is dead, the battery calendar function will not work, and the date files were saved to memory will not be reflected. Other functions, such as saving to memory, will work normally. For information on replacing the backup battery, please see here.
This issue has not occurred with any products other than those listed in the table below. For further details, please contact your nearest sales office or customer service center.
