8.4.2 Troubleshooting at unpacking
This section describes the procedure needed to interrupt the unpacking procedures in order to inspect
or repair the equipment when trouble occurs during unpacking.
Turn ON the power of the equipment to start the unpacking operation by the software after No. 51of the
unpacking instructions.
This instruction prohibits any operation not described in the unpacking instruction, because the purpose
is to complete the setup of the equipment.
Therefore, if trouble of the equipment occurs during unpacking, it is necessary to forcibly shut down the
unpacking procedure.
When an error code or a service call is displayed after the unpacking procedure is interrupted, clear the
trouble referring to troubleshooting.
When the equipment has been shut down, starting the equipment with the setting code "08-9022"
allows you to know the completed status before the forced termination.
For example, if 6 is displayed for the code 08-9022, this status means that the gamma adjustment has
been completed.
When the error has been cleared, restart the unpacking procedures from the status in which you shut
down the equipment.
Additionally, setting the code 08-9022 to 5 enables you to perform the gamma adjustment again.
Also, setting the code 08-9022 to 99 allows you to release the unpacking operation and to start the
equipment normally.
