SELF-DIAGNOSTIC MODE
5 - 15
5.9 Assist Mode (3C)
5.9.1 Functions
This equipment has the Assist Mode to enable the following functions.
(1) Update error flag clearing (Clear Error Flag in Software Installation)
Even if the firmware downloading has been completed normally, the Recovery Mode may
accidentally start up when the power is turned ON again. In this case, clear the Update Error
flags used in the download process with this function. (Normally, the flags are automatically
cleared in the download process.)
Also in the case the Recovery Mode accidentally starts up after the replacement of SRAM on the
SYS board, the flags are cleared with this function.
(2) Data storage partition formatting (Format Root Partition)
When a defect occurs on the UI data, etc. which are stored in the HDD, the partition with the
stored UI data, etc. is formatted with this function.
Do not use this function since it is not normally necessary.
(3) HDD partition creation (Format HDD)
When the HDD is replaced or UI data, etc. are downloaded using the USB storage, it is
necessary to format a partition in the HDD before downloading. In this case, the partition is
created in the HDD with this function.
HDD data must be installed after performing this function.
• When downloading with a download jig, it is not necessary to format a partition in advance.
• Perform the HDD partition formatting only when a new HDD and scrambler board are installed
since all data in the current HDD are erased by this operation.
(4) SRAM data format (Clear SRAM)
When SRAM is replaced with a new one, abnormal values may be written in the new SRAM.
SRAM data must be formatted with this function for such case.
• This function is required only when a new SRAM is installed.
• Do not perform this function in cases other than the installation of a new SRAM because all
data in the SRAM will be deleted with this function.
