Instruction Manual
BATTERY INSTALLATION
NOTE: When the temperature falls below freezing point 
32°F (0°C), battery voltage will drop which may result in 
reduced the transmission range. For optimum in cold 
conditions, we recommend using lithium batteries.
NOTE: Install the batteries and select the channel before 
mounting the remote sensor.
• Remove the screws from the battery compartment with a small 
 Phillips screwdriver (not included).
• Set the channel 1 through 3. The switch is located in the battery 
 compartment. Channel 1 is typically selected if only one 
 remote sensor is being used.
• Install 2 “AA” size alkaline batteries (not included) matching 
 polarity as shown in the battery compartment.
• Replace the battery compartment door and secure the screws.
• Secure the remote sensor in the desired location.
MOUNTING
• The remote sensor can be mounted either horizontally or 
 vertically.
• Use a screw, rather than a nail, to securely mount the sensor.
• When mounting the main unit on a vertical surface, fold the 
 built-in table stand back into the unit, allowing the main unit to 
 lie flush with the surface.
PLACEMENT
• The remote sensor should be placed under eaves or a similar 
 location with free air circulation sheltered from direct sunlight 
 and extreme weather.
• Ideally, place the remote sensor over soil, rather than asphalt 
 which would cause false readings.
• Avoid placing the remote sensor near sources of heat, such as 
 chimneys and heating elements
• Avoid areas that collect heat from the sun and radiate heat, 
 such as metal, brick or concrete structures, paving, and patios
• The international standard for the valid air temperature 
 measurements is 4 feet (1.25meters) above the ground
OPERATION
Immediately after batteries are installed, the remote sensor will 
start transmitting a temperature data to the main unit.
