The screen is in a blank “sleep” state during most operation, even when the system is operating. 

This is a feature to increase battery life and prevent tampering. 

To enter the Menu options, press the Wakeup button on the unit. The large round button blinks to 

indicate it is awake. 

The display remains disabled until any LCD menu control button is pressed. The LCD menu control 

buttons are Up or Down as shown in the following.
