20 Function settings
Functional characters such as current date and time or lot are based on the system clock of the laser
marking system ("System settings" > "System clock configuration"). It may happen that the system
clock deviates from the accurate time due to errors of internal parts or low battery level.
Therefore, check the system clock in the laser marking system regularly to ensure that the date and
time are correct.
