If your WeatherTRAK ET plus display screen is blank, you can go through the following steps to make the display screen visible again.

1.  Make sure your controller is connected to a working power source.

2.  Make sure the MAIN knob is turned to the RUN position. 

3.  If you still don’t see a display, try powering down the unit. Wait 30 seconds, then restart.

4.  Adjust the contrast on the screen to match the light conditions at the location of your controller.  

• Turn the MAIN knob to DISPLAY/ADJUST
  
  
• Turn the Upper Line knob to adjust the contrast. Turning the knob clockwise will make the lettering darker. Turning the knob counterclockwise will make it lighter.
  
  
• To finish, turn the MAIN knob back to the RUN position.
