FAQ
■ FAQ on Installing Firmware
No.1
Q: Is it also possible to downgrade firmware with using CDS?

If download and update are performed consecutively, firmware can’t be downgraded.

UGW-linked Download and Update No
UGW-linked Download Yes
Manual Download and Update(Timing to Apply : Manual) Yes
Manual Download and Update(Timing to Apply : Automatic) No
No.2
Q: When installing firmware, does it take less time in “manual download and update” compared to “update via SST”?
A: It depends on the number of devices to update firmware.
When updating the firmware on a device, it takes more time in “manual download and update” compared to “update via SST” (It
depend on network environment.).
As for the time to update firmware to multiple devices, “manual download and update” takes less time compared to “update via
SST” because updating the firmware to multiple devices can be executed simultaneously.
No.3
Q: How can we confirm that the firmware is properly updated after “UGW-linked download and update” done?
A: You can confirm this in E-mail or the Device List on UGW-linked screen.
E-mail to notify firmware update will be sent from CDS server to the addresses set as 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 find the distribution status per device as
shown in the search result.
No.4
Q: In the course of “UGW-linked download”, what will happen if the user downloads the firmware before the service technician
update the firmware downloaded with “UGW-linked download” before?
A: The previously downloaded firmware in the method of “UGW-linked download” will be overridden by the subsequently
downloaded one.
This is because only one downloaded firmware can be held on the device.
The firmware downloaded in the method of “Service mode-linked download” and “UGW-linked download” can be checked/deleted
from [Settings/Registration] screen, but cannot be updated, so it cannot be updated by the user unnoticed by the service
technician.
No.5
Q: What happens if the user registers another distribution schedule when the distribution schedule has been set in “manual
download and update”?
A: The distribution schedule subsequently registered by the user will override the existing schedule. This is because only one
distribution schedule can be held. Any existing distribution schedule is deleted and the newly registered distribution schedule is
made valid.
