Warning
When updating from version r7.x
(version lower than r8.0
) to version e.g. r8.2
, you must first update to version r8.0
(click here to download). Only then can you update freely to any version. This intermediate step is crucial!
Upload the firmware file named
device.upd
to the USB drive.Connect the USB drive to the clock using the USB-C connector on the clock PCB.
Open the clock menu, go to the
SYSt
submenu and proceed to enter.Navigate to menu item
c2
(see Firmware update via USB process settings chapter).Setting the item
c2
to value1
will activate the firmware update process.Hint
First step of the Firmware update process is to load the USB device.
The display will show a flashing
FU:xx
, wherexx
represents the result of the process:0
:USB drive connected
-1
:USB drive not found
If the USB drive is not found, format the USB drive to NTFS format.
If
FU: 0
is displayed, the file transfer can be started by pressing OK button on IR remote controller or by pressing PB2L.If the file on the USB drive is OK, the message stops flashing and
FU:xx
is displayed with only flashing colons, wherexx
already repserents the percentage progress of the file transfer.If the file is invalid for the device,
FU:-3
will flash or if the file is not found,FU:-2
will flash.
When the file transfer is complete, the
dONE
message is displayed and the clock resets after 2 seconds to complete the update process.
Note
Until the file transfer starts, the menu can be exited by pressing the PB1L push-button or the ESC button on the IR remote control.
If the file transfer process fails and the copy process does not complete, the clock must be manually reset, as the clock control by the buttons or IR remote controller is ignored during the file transfer – see Factory Reset Using Push-Buttons chapter.
