2.2 FAX SC CODES

2.2.1 SC1201

SC1201 indicates an unrecoverable error. The fax unit does not operate until you
initialize the SRAM. When you initialize it, all user-specified data and SP settings
are lost. There is no way to recover these data. SC1201 can be generated under
any of the following conditions:
• The SRAM backup battery is dead.
• The switch of the SRAM backup battery is open.
• The SRAM on the MBU is physically defective.

2.2.2 OTHER SC CODES

The FCU resets itself automatically by default. The data in the SAF memory is
retained. When you want to prevent this automatic resetting, change Bit 7 of the
System Switch 1F (! 3.2.1). The FCU displays an SC code and does not operate
until you reset it. To reset it, perform as follows (either of them):
• Hold down the  and  keys until the FCU is reset (for about 10 seconds).
• Turn the main power switch off and on.
