Overview

Removable media (SD card or USB flash drive) are a precision device, so when you handle them, respect the following.
When the power is switched ON, do not insert or remove the removable media.
During installation, do not switch the power OFF.
Since the removable media is manufactured to high precision, do not store it in a hot or humid location, or in direct sunlight.
Do not bend the removable media, scratch it, or give it a strong shock.
Before downloading firmware to an SD card, check whether write-protection of the SD card is canceled. If write-protection is enabled, an error code (error code 44, etc.) will be displayed during download, and the download will fail.
Before updating the firmware, remove the network cable from this machine.
During software update, disconnect network cables and interface cables, remove wireless boards, etc., (so that they are not accessed during the update).
