If an active collar or active ear tag is not being used, it should always be put to sleep in order to conserve the internal battery.

To put an active device to sleep:

HOLD the magnet over the magnet icon for 8 seconds.
The LED will emit a single flash to indicate that it has been put to sleep.

Tip: If an animal has left your farm, don't forget to use the Datamars Livestock web app to mark the animal as 'sold' or 'died' in order to keep the database up-to-date.
