 buttons. In the 

standby mode, the LCD will display all segments (helpful when troubleshooting display problems). Press 

the 

 button to begin the Quick Check™ test procedure. Within seconds, the system searches all 

stations in an effort to detect a high current path through the station terminals. When a field wiring 

short is detected, an ERR symbol preceded by the station number will momentarily flash on the 

controller LCD display. After the Hunter Quick Check™ completes running this circuit diagnostic 

procedure, the controller returns to the automatic watering mode.
