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.
