Reset / Resetting the device to factory settings
In a number of particular cases, the Reset button can be used to fully reset the MB
panel and restore the factory default settings.
When could this function be of use?
If, for example, you have copied the local file required for an FTP connection
with the local server into the wrong directory or have unintentionally deleted data
which is necessary for displaying the Setup menu. The most common error is the
appearance of the message
"uBTerminal not found”
, while the content on screen
remains unchanged. In such a case, proceed as follows:
1.
Switch off the MB panel with OFF
2.
Activate the Reset button, at the top of the device’s rear cover, by holding down
the button(see "1.2 Definition of the connectors" on page 1-2
and "6.1.2 Secure
Firmware Download via USB" on page 6-1
.
Simultaneously switch on the MB panel at the same time. After approx. 30 sec.,
the panel goes to the reset mode.
3.
Release the Reset button when the display show the message "Booting Up" and
wait.
4.
You may have to wait to 1 to 2 minutes. During this time, the FW is reconstruct
-
ing the whole organisation of the memory and recreating all the files which are
required for the default settings. Finally, the MB panel reboots automatically, and
you will be asked to recalibrate the touchscreen. Once you have calibrated it, the
system has been fully restored.
6.3 Backlight
The period for which the backlight remains on can be set manually. This function
helps to save energy. If the backlight is deactivated, you will save approx. 3/4
watts, which is a non-negligible value. This will also extend the
service life
of the
backlight.
Service life of the backlight
The
normal
service life of the backlight (at 25°C) is defined as approx. 50 Kh. This
corresponds to 5 years of continuous use. However, this value is
quickly reduced
(to half or less) if the operating temperature is 10°C or less. It makes sense for
the user to take this into account and to adapt the standby period of the backlight
accordingly.
