
Mount at least 6 feet in the air for a strong RF (radio frequency) signal.

Do not mount the remote sensor on a metal fence. This significantly reduces the
effective range .

Remote sensors are water resistant, not waterproof.
Indoor:

Mount the Remote Sensor indoors to monitor high mold risk areas like in a crawl space
or a basement.
Indoor or Outdoor:

Mount remote temperature sensor vertically.

Avoid more than one wall between the remote sensor and the weather station.

The maximum transmitting range in open air is over 200 feet (60 meters).

Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce
the range.

Do not mount near electrical wires, transmitting antennas or other items that will
interfere with the signal.

RF (radio frequency) signals do not travel well through moisture or dirt.
MOUNT
Option 1:

Install one mounting screw (not included) into a wall.

Place the remote sensor onto the screw (hanging hole on the backside).

Gently pull down to lock the screw in place.
Option 2:

Insert the mounting screw through the front of the remote sensor and into the wall.

Tighten the screw to snug (do not over tighten).
Position Weather Station

The weather station has a pull out stand to sit on a desk or table or can be wall
mounted.

Place within range of the remote sensor.

The maximum transmitting range in open air is 200 feet (60 meters).

Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce
the range.

Choose a location 6 feet or more from electronics such as cordless phones, wireless
gaming systems, televisions, microwaves, routers, baby monitors, etc., which can
prevent signal reception.

Be aware of electrical wires and plumbing within a wall. This will interfere with RF (radio
frequency) signal reception.
Distance/Resistance/Interference
Distance:

The maximum transmitting range in open air is over 200 feet (60 meters) between the
remote sensor and the weather station. This range is in open air with ideal conditions.

Consider what is in the signal path between the weather station and the remote sensor.

Avoid placing electronics in the signal path between the weather station and the remote
sensor.
