zactrack systems do not have a specific shut down routine. The Trackers don't have a power button. If you don't need them store them in the charger. In a case of a long term storage, please be sure to charge them every 6 months to refresh the battery.

The pucks have a normal power button at the bottom.

The zactrack MINI anchors and also the Main Anchor have power buttons. If you don't need them just perform a long press on this button to shut them down. The MINI Anchors and the Master, stores their power state. When you plug them into the charger they will be on. With the unplugging of the charger the device will fall back to the state before charging.
