As long as the proper voltage is maintained, there are no special maintenance concerns apart from the following care:

• To meet limited warranty requirements and to ensure the longevity of the PDLC film within the glass it is important that Switchable Privacy Glass is switched off for a minimum of 4 hours out of every 24 hours.
• Timer: A 24-hour timer is highly recommended to be installed for each power supply/transformer or group of power supplies/transformers to ensure that the privacy glass is turned ‘off’ for the minimal 4 hour period. If a timer is not used, switching ON and OFF daily is encouraged to ensure that the panels remain functional.
