15 Screen saving (screen blanking).
The device is equipped with a feature that allows for turning off the backlight. This option is
marked with the SCr sign. With this feature, the display is turned off after about 60s (if the keys
of the device are not pressed). Of course, the device continues its operation without interfering
with other parameters. Press any key to restore the backlight.
16 Default settings and device errors.
If you have any difficulty accessing the device menu, e.g. it is not possible to enter a particular
menu level or it is necessary to restore the device to its default settings, follow the instructions
below.
In the first case, when a particular menu level cannot be accessed or menu items are displayed
incorrectly, this may indicate that a saving-inmemory error has occurred. In such a case, try to
restore the device to its default settings before sending the F6324265 to the service center. If,
after restoring to its default settings, the device still does not operate correctly, please send it
to our service center.
16.1 Restore default settings.
To restore the device to its default settings, press and hold the “previous” key while switching
on the device. One of the messages that will be displayed will say dFl, which means successful
restoring to default settings (the “previous” key has to be held down while powering on the
device, until the dFl message is displayed).
If this message is accepted by pressing “enter”, the default settings will be restored. The user
can also exit this menu level without restoring the default settings. In order to do this, press the
“escape” key.
