Distance/Resistance/Interference
Distance:
•
The transmitting range in the open air is over 300 feet (91 meters) between the outdoor
sensor and the weather station. This range is in the open air with ideal conditions.
•
Consider what is in the signal path between the weather station and the outdoor sensor.
•
Avoid placing electronics in the signal path between the weather station and the outdoor
sensor.
Resistance:
•
Obstacles such as walls, floors, windows, stucco, concrete, and large metal objects can
reduce the range.
•
When considering the distance between the outdoor sensor and the weather station (300
feet open air), cut that distance in half for each wall, window, tree, bush, or other
obstruction in the signal path.
•
Closer is better.
•
Windows reflect the RF (radio frequency) signal.
•
Metal absorbs the signal and reduces the range.
•
Stucco has a metal mesh that absorbs the signal.
•
Do not mount the outdoor sensor on a metal fence. This significantly reduces the effective
range.
Interference:
•
Consider items in the signal path between the outdoor sensor and the weather station.
•
Sometimes a simple relocation of the outdoor sensor or the weather station will correct the
interference.
•
Windows can reflect the radio signal.
•
Metal will absorb the RF (radio frequency) signal.
•
Stucco has a metal mesh that absorbs signal.
•
Avoid transmitting antennas: (ham radios, emergency dispatch centers, airports, military
bases, etc.)
•
Electrical wires (utilities, cable, etc.)
•
Vegetation is full of moisture and reduces signal.
•
It is difficult for RF (radio frequency) signal to travel through a hill.
Temperature Alerts
Explanation:
The outdoor and indoor temperature alerts are set in two separate steps.
•
Set the alert value.
•
Arm/Disarm the alert.
Select Temperature Alert Values:
1. Hold 2 seconds, then release the
ALERTS
button to enter alert set mode.
2. Outdoor HI TEMP will flash OFF or ON.
3. Press and release the
+ (PLUS)/-
buttons to select ON.
(If disarmed (OFF) skip the alert value and move to the next alert)
4. Press and release the ALERTS button and the alarm value will flash.
