Defines the SR2's behaviour in the event of a network or mains power failure.

Set on DIP switch 1.

ON

(default)

In the event of a mains power failure, the SR2 will switch to Fallback Mode.

The Receiver will only be powered up for 5 minutes in every 20.

This will prolong the power of the on-board battery, but may cause gaps in the logged data.

In the event of a network communications failure lasting 60 minutes, the SR2 will switch to Fallback Mode.

The Receiver will only be powered up for 5 minutes in every 20.

This will increase the amount of time data can be logged before the System wraps-around and starts to overwrite older data.

OFF

In the event of a network communications or mains power failure, the SR2 will continue to log all data received until its on-board back up power is depleted.

If network communications are not restored when the memory becomes full, older data will be overwritten.
