Instruction Manual
INSTALLATION
Communications between the main unit (receiver) and the 
remote sensor (transmitter) is wireless. This allows you to 
greater flexibility in choosing the location of remote sensor. The 
remote transmits data up to 100 feet (30 meters) over an open, 
unobstructed area.
The remote sensor can be located either indoors or outdoors, 
allowing you chose where your data is obtained.
NOTE:
• It is critical to power the remote sensor BEFORE setting up the 
 main unit. 
• It is critical to power up and test communication between the 
 remote sensor and the main unit BEFORE permanently 
 mounting the remote. 
BEFORE YOU BEGIN
• We recommend using alkaline batteries for the remote sensor 
 and the main unit. If outdoor temperatures regularly fall below 
 32°F (0°C), we recommend using lithium batteries.
• Avoid using rechargeable batteries. (Rechargeable batteries 
 cannot maintain correct power requirements.)
• ALWAYS install batteries in the remote sensor before the 
 main unit.
• Insert batteries before first use, matching the polarity as shown 
 in the battery compartment.
• Press RESET after each battery change with a paper clip or 
 similar tool.
• During initial set up, place the remote sensor close to the main 
 unit. 
• After reception is established (remote readings will appear on 
 the main unit’s display), position the remote sensor and the 
 main unit within the effective transmission range of up to 100 
 feet (30 meters).
• The main unit must be placed indoors.
NOTE:
• Avoid pressing any buttons on the main unit before the remote 
 readings are displayed.
• Transmission or reception range may be affected by trees, 
 metal structures, electronic appliances, surrounding building 
 materials and how the main unit and transmitter are positioned.
• Place the remote sensor so that it faces the main unit (receiver), 
 minimizing obstructions such as doors, walls and furniture.
