All Series 3 and 4 players have a real-time clock (RTC); however, the LS424 does not have a supercapacitor to keep the clock running when there is no other power source. If you power cycle an LS424, the player will lose its configured time settings, and (unless the player can reach a local/remote timeserver) it will not be able to play day-parted presentations at scheduled times or communicate with SSL servers (including the BrightSign Network).
Player Security
XTx44/XDx34 players don't accept "{A|A}" AES encryption keys (i.e. where the top and bottom 64 bits of the key are identical).
