2.4 FAX SC CODES
2.4.1 OVERVIEW
When the FCU detects a Fax SC Code condition, it resets itself automatically
(default setting). This initializes the FCU without erasing files in the SAF memory or
resetting the switches.
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.
2.4.2 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 SW1 on the MBU is at the “OFF” position.
•
The SRAM on the MBU has a physical defect.
•
SD card connection was loose.
