transmission range of up to 328 feet (100 meters). Ideally they should be placed 
within the line of sight of the main unit. 
• Transmission range may be affected by trees, metal structures and electronic
appliances.
• The effective operating range may be influenced by the surrounding building
materials and how the receiver (main unit) and transmitters (weather sensors) 
are positioned. 
• Place the remote thermo-hygrometer so that it faces the main unit (receiver),
minimizing obstructions such as doors, walls and furniture.
Note: When the temperature falls below freezing, the batteries in the outdoor 
remote thermo-hygrometers may have reduced voltage supply and a shorter 
effective range. We recommend using lithium batteries at temperatures of 32°F (0°C) 
and below.
