FAX SC CODES

2.2 FAX SC CODES

2.2.1 OVERVIEW

When the FCU detects a Fax SC Code condition other than SC1201, it resets itself
automatically (default setting). This initializes the FCU without erasing files in the
SAF memory or resetting the switches.
NOTE: For details on Fax SC Codes 1201, refer to the following sections.
If bit 7 of System Switch 1F is changed to "1", when the FCU detects a Fax SC
Code condition, it displays the code on the display and stops working until the fax
unit is initialized using one of the following methods:
• Hold down the "7" and "9" keys for more than 10 s.
• Turn off the main power switch and turn it back on.

2.2.2 SC1201

When the FCU detects an unrecoverable error in the SRAM, which requires a
complete SRAM initialization, the fax unit displays this SC Code and stops.
There is no way to recover from this error condition without a complete SRAM
initialization (all the user and service programmed data will be erased).
The possible causes are:
• SRAM backup battery defect, or CN1 on the MBU is at the "OFF" position
• SRAM on the MBU has a physical defect
