IMPORTANT NOTE
In the event of power interruption, the MegaPower LT will lose current camera and monitor
selections and revert to its default settings upon reconnection of the supply.
All monitor and camera pairings must be re-entered if required. However, any tours or
views that were active do not need to be re-entered as they will restart.
If this recovery action is not sufficient for the application, it is recommended that the unit
and its associated equipment is supplied from a secure and uninterruptible power supply.
