FAQ■on■Installing■Firmware
No.1
Q:■ Is■it■also■possible■to■downgrade■firmware■with■using■CDS?
A:■Firmware■can■be■downgraded■in■some■methods■shown■in■the■table■below.
If■download■and■update■are■performed■consecutively,■firmware■can’t■be■downgraded.
Distribution■Method
Downgrade■Possibility
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■User■mode,■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.
No.6
Q:■ How■is■an■individual■response■edition■of■firmware■distributed?
A:■Any■individual■response■edition■of■firmware■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.7
Q:■ If■the■device■is■down■during■firmware■update,■can■the■device■be■started■using■the■older■
firmware■version?
A:■No,■it■is■impossible■to■start■the■device■using■older■versions.■If■this■occurs,■the■service■
technician■in■charge■should■reinstall■the■firmware■via■SST.■See■"Troubleshooting■on■
Firmware■Installation"■in■chapter■6■of■this■manual■for■details.
No.8
Q:■ If■the■device■is■down■during■firmware■download,■is■it■possible■to■download■the■firmware■
again?
A:■Firmware■cannot■be■downloaded■again■automatically.■Instead,■the■error■is■notified■in■E-mail.■
The■user■should■register■the■firmware■distribution■schedule■again■accordingly.
