Problem 
Solution 
Wireless remote (thermo-hygrometer) not 
reporting in to console. 
The temperature and humidity are blank 
the display console. 
The maximum line of sight communication range is 
300’. Move the sensor assembly closer to the display 
console. 
If the sensor assembly is too close (less than 10’), move 
the sensor assembly away from the display console. 
Cycle power on the console. The console may have 
exited the search mode. 
Install a fresh set of batteries in the remote 
thermo-hygrometer. 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.
