Your wireless z screen displays the last z sensor readings for any active ports every five minutes (24-hour minimum/maximum) as well as the battery life and signal strength of the device. Below is an example of what you will see on the screen:
If you notice that the z screen has turned off, there could be a connection loss, missed broadcast, or another interference with the z sensor, and the z screen will enter sleep mode. The z screen will try to re-sync on its own in a continual sequence but will eventually enter "eternal sleep," denoted by the home screen with the SmartSense logo.
When a z screen sleeps, you can press the power button to force the screen to enter searching mode to try and re-sync to the z sensor.
If this does not work, contact the SmartSense Support team to reset the device.
