INITIAL SET UP 
 

DO NOT MIX OLD AND NEW BATTERIES. 
 
DO NOT MIX ALKALINE, STANDARD, OR RECHARGEABLE BATTERIES 

 

1. 

Insert the batteries into the Temperature transmitter. Keep the transmitter 5-10 feet from the Weather 
Station during set up. 

2. 

Within 45 seconds, insert batteries into the Weather Station. Once the batteries are in place all 
segments will light up briefly. The time will be displayed as 12:00.  If this is not displayed within 80 
seconds, remove the batteries from both units for 2 minutes and start again from step 1. 

3. 

The weather station will start receiving data from the transmitter. The outdoor temperature and signal 
reception icon will be displayed.  If this is not displayed within 80 seconds, remove the batteries from 
both units for 2 minutes and start again from step 1. 

4. 

Allow the weather station and the transmitter to remain 5-10 feet apart for 15 minutes after set up to 
establish a strong connection. 

5. 

To ensure sufficient 915 MHz transmission after set up, the distance between the transmitter mounted 
outside and the weather station inside should not exceed 330 feet (100 meters) distance (open air, no 
obstructions).   

6. 

Test the weather station and the transmitter in the positions they will be located for one hour before 
permanently mounting. If the outdoor temperature signal goes to dashes restart from step 1 and try a 
new location.
