For best results:  
SETUP SENSOR  
Insert the batteries and select the channel and  
temperature unit before you mount the sensor.  
Open the remote sensor battery compartment with a  
small Phillips screwdriver.  
Place the sensor out of direct sunlight and  
moisture.  
1. Insert the batteries, matching the polarity as shown  
in the battery compartment.  
Do not place the sensor more than 30 meters  
(98 feet) from the main (indoor) unit.  
2. Set the channel. The switch is located in the battery  
compartment.  
Position the sensor so that it faces the main  
(indoor) unit, minimizing obstructions such as  
doors, walls, and furniture.  
SWITCH  
Channel  
OPTION  
Place the sensor in a location with a clear view  
to the sky, away from metallic or electronic  
objects.  
Channel 1 - 3. If you are using  
more than one sensor, select a  
different channel for each sensor.  
Position the sensor close to the main unit  
during cold winter months as below-freezing  
temperatures may affect battery performance and  
signal transmission.  
3. Place the sensor near the main unit. Press RESET  
on the sensor to initiate signal sending between the  
sensor and the main unit. The reception icon on  
the main unit will blink for approximately 3 minutes  
while it is searching for the sensor. (Refer to the  
Sensor Data Transmission section for more  
information.)  
You may need to experiment with various locations to  
get the best results.  
4. Close the remote sensor battery compartment.  
5. Secure the sensor in the desired location using the  
wall mount or table stand.
