TROUBLESHOOTING:  
ß
At times, the main unit may display ì---ì in the remote  
temperature screen if outside interference is occurring. Most  
of the time the unit will re-sync the signal on itís own.  
However, if this should continue to occur, the following may  
also be the reason:  
A. Low battery indicator(s).  
3. On the main unit, select between Celsius and Fahrenheit  
temperature readings by pressing the + C/F button.  
B. The sensor has been placed outside of the effective  
transmission range (more than 100 feet). Move the  
sensor closer to the main unit.  
4. To add an additional sensor make sure batteries are in the  
main unit first, then place batteries in the additional sensor and  
press the reset or Tx button. The main unit automatically  
searches for an open channel to register the signal for the new  
sensor.  
C. Sensor units may have outside interference that is  
preventing proper transmission. Sources of interference  
include but are not limited to metal surfaces, electrical  
devices, etc. The sensor may need to be relocated if  
interference continues.  
Low Battery Indicator:  
The low battery indicator will appear on the LCD displays of both  
the main and sensor units. To replace the batteries, follow the set-  
up procedure above.
