Problem 

Solution 

Wireless remote (probe thermometer) not 
reporting in to console. 
 
There are dashes (--.-) on the display 
console. 

If  any  of  the  sensor  communication  is  lost,  dashes  (--.-) 
will be displayed on the screen. To reacquire the signal, 
press  and  hold  the 

C

  button  for  3  seconds, 

and  the  remote  search  icon 

  will  be  constantly 

displayed.  Once  the  signal  is  reacquired,  the  remote 
search  icon 

  will  turn  off,  and  the  current  values 

will be displayed. 
 
The maximum line of sight communication range is 300’ 
and 100’ under most conditions. Move the sensor 
assembly closer to the display console. 
 
If the sensor assembly is too close (less than 5’), move 
the sensor assembly away from the display console. 
 
Make sure the remote sensor LCD display is working 
and the transmitter light is flashing once per 60 seconds. 
 
Install a fresh set of batteries in the remote probe 
thermometer. For cold weather environments, install 
lithium batteries. 
 
Make sure the remote sensors are not transmitting 
through solid metal (acts as an RF shield), or earth 
barrier (down a hill). 
 
Move the display console around electrical noise 
generating devices, such as computers, TVs and other 
wireless transmitters or receivers.
