temperatures), deviation may be more important (worst case: - 14 seconds per 48
hours).
If the terminal is used in an application requiring high time precision, we recommend
synchronizing regularly your terminal time with an external clock (using NTP). Every 24
hours is usually enough for most applications.
Please note that the date/time of the terminal is protected from power failure during
at least 24 hours. If the duration of the power failure or power down is longer, the
date/time of the terminal will be lost.
Cleaning precautions
The use of a dry cloth is recommended to clean the terminal, especially the biometric
sensor. Acid liquids, alcohol or abrasive materials are prohibited.
