QUICK SET-UP GUIDE 
 
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries. 
 

1.  Have the indoor weather station and remote temperature sensor 3 to 5 

apart. 

2.  Batteries should be out of both units for 10 minutes. 
3.  Place the batteries into the 

remote temperature sensor

 first then into 

the indoor weather station. 
(All remote temperature sensors must be started before the indoor 

weather station) 

4.  DO NOT PRESS ANY BUTTONS FOR 10 MINUTES. 

 
In this time the indoor weather station and remote temperature sensor will start to 
talk to each other and the indoor weather station will show both the indoor 
temperature and an outdoor temperature.  If the indoor weather station does not 
display both temperatures after the 10 minutes please retry the set up as stated above.  
After both indoor and outdoor temperatures are displayed for 10 minutes you can 
place your remote temperature sensor outdoors and set your time. 
 
The remote temperature sensor should be placed in a dry, shaded area.  The remote 
temperature sensor has a range of 80 feet.  Any walls that the signal will have to pass 
through will reduce distance.  An outdoor wall or window will have 20 to 30 feet of 
resistance and an interior wall will have 10 to 20 feet of resistance.  Your distance 
plus resistance should not exceed 80 ft. in a straight line. 
 

NOTE:

  Fog and mist will not harm your remote temperature sensor but direct rain 

must be avoided. 
 
To complete the set up of your indoor weather station after the 10 minutes have 
passed please follow the steps on pages 8 and 9. 

 

Note:  The remote temperature sensor transmits a signal every 3 minutes; 
after the batteries have been installed, the indoor weather station will 
search for the signal for a duration of 5 minutes.  If there is no temperature 
reading in the OUTDOOR LCD after 5 minutes, make sure the units are 
within range of each other or repeat the battery installation procedure.
