Note: It is critical to power up and test communication
between the remote sensor and the main unit BEFORE
permanently mounting them outside.
Before you begin
• We recommend using alkaline batteries for the remote
thermo-hygrometer when temperatures are above 32ºF
(0ºC) and lithium batteries when temperatures are below
32ºF (0ºC).
• Avoid using rechargeable batteries. (Rechargeable batteries
cannot maintain correct power requirements).
• Insert batteries before first use, matching the polarity in the
battery compartment
• Remove protective plastic screen from LCD display (if
any).
• During an initial setup, place the main unit close to the
remote sensor.
• After reception is established (the 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 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
32ºF (0ºC) and below.
