Assist Mode

4.3.1 Assist mode
This equipment has the Assist Mode to enable the following functions.
(1) Update Error flags clearing ("Clear update Error Flags.")
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 Loader Partition.")
When a defection 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 ("All Partition Delete and Create Loader Partition.")
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.
Notes:
1. When downloading with a download jig, it is not necessary to format a partition in advance.
2. Perform the HDD partition formatting only when a new HDD is installed since all data in the
current HDD are erased by this operation.
(4) SRAM data format
When SRAM board is replaced with a new one on the SYS board, abnormal values may be
written in the new SRAM. In such cases, SRAM data must be formatted with this function.
Notes:
1. This function is required only when a new SRAM board is installed.
2. Do not perform this function in cases other than the installation of a new SRAM board
because all data in the SRAM will be deleted as a result.
