Make your HDX vault even faster with Liberty’s DC adapter that
fits a vehicle’s 12V outlet. The DC adapter for HDX models keeps your
vault “awake” and ready to go! With the DC adapter plugged into the
unit, access to your vault is under 1-second. Without the DC adapter,
HDX vaults require an additional second to “wakeup” (less than 2-seconds
total).

CAUTION:
Use only Liberty’s DC Adapter on HDX Smart Vaults. Using any another DC
adapter could damage the circuit board inside the HDX vault and
void the warranty.
