System messages
The device displays system messages to signal that certain program se-
quences were shortened. System messages inform the user about which
options are available for further operation.
Example:
Event messages in the display
The device displays event messages to signal that the device has deviated
from an intended state. Event messages inform the user about which op-
tions are available for further operation.
When the event message ‘Notice’ is displayed, you can continue working
with the device. These event messages signal that the device was not able
to execute a task as intended in the program. Example: battery is too weak.
When the event message ‘Error’ is displayed, a technical problem has
occurred. If this event message is displayed again after a restart and when
performing the same task, the accuracy and proper function of the device
can no longer be guaranteed. Example: motor is blocked.
If the same event messages are repeatedly displayed, please contact
BRAND.
