SELF-DIAGNOSTIC MODE
5 - 28
5.12 SRAM Clear Mode (6C)
5.12.1 Overview
This is a mode in which you can clear particular errors such as F800 or F900 without entering a Service
Technician password.
For example, when SYS-SRAM is in an abnormal status or needs replacement but service technicians
cannot log into the 3C mode, SRAM can be initialized by entering the SRAM clear mode (6C) and
selecting item 1 below.
The content of item 1 in this mode is the same as that of item 4 in the 3C mode (Clear SRAM).
Use this mode to clear the SRAM data when a particular error occurs or service technicians cannot log
in with their password and therefore cannot use the 3C mode.
Functions:
• Sets the serial number of this equipment.
• Clears SRAM data when the 3C mode cannot be used.
• Clears F800 error.
• Clears F900 error.
