Q: How can we conrm that the rmware is properly updated after “UGW-linked download
and update” done?
A: You can conrm this in E-mail or the Device List on UGW-linked screen.

destinations at the time of distribution setting to notify update completion.
On UGW-linked screen, search the device of your interest on [Select Device] screen to nd

Q: In the course of “UGW-linked download”, what will happen if the user downloads the
rmware before the service technician update the rmware downloaded with “UGW-linked
download” before?
A: The previously downloaded rmware in the method of “UGW-linked download” will be
overridden by the subsequently downloaded one.
This is because only one downloaded rmware can be held on the device.
The rmware downloaded in the method of “Service mode-linked download” and “UGW-
linked download” can be checked/deleted from User mode, but cannot be updated, so it
cannot be updated by the user unnoticed by the service technician.
No.4
Q: How is an individual response edition of rmware distributed?
A: Any individual response edition of rmware can be installed in all the methods provided by
service technicians. Before installing the individual response edition, ensure to obtain the
ID and password separately.
No.5
Q: If the device is down during rmware update, can the device be started using the older
rmware version?
A: No, it is impossible to start the device using older versions. If this occurs, the service
technician in charge should reinstall the rmware via SST. See "Troubleshooting on
Firmware Installation" in chapter 6 of this manual for details.
No.6
Q: If the device is down during rmware download, is it possible to download the rmware
again?
A: Firmware cannot be downloaded again automatically. Instead, the error is notied in E-mail.
The user should register the rmware distribution schedule again accordingly.
