14.4 Time function
Does not apply to ET-5x6-A-*:
When the ET-3x6-A-* and ET-4x6-A-* HMI devices are switched off, their clock function is
maintained by a battery and a capacitor. As long as the battery is intact, the clock function is
maintained. Once the battery fails, the capacitor takes over and maintains the clock function for
about four days. If the HMI device is switched on after a longer interval than that, the time and
date have to be re-set manually or via a connected system.
