MOON PHASE
Our weather station is equipped with 8 moon phases display (i.e. from new moon to waning crescent) on the screen.
WEATHER FORECAST
Our weather station is capable of detecting local barometric pressure changes, and based on the data collected, can
predict the weather for the next 12 to 24 hours.
Note
1. The accuracy of a general pressure-based weather forecast is about 70 to 75%, and therefore, we
cannot be held responsible for any inconveniences so caused by an inaccurate one.
2. The weather forecast is meant for the next 12 to 24 hours. It may not necessarily reflect the
current situation.

Snowfall Indicator
The snowfall indicator is consisted of the cloud and snowflake icons (positioned over the raining icon) when the air
pressure goes to predict rainy or stormy weather & the temperature falls less than 30.2°F(-1°C)
Note: This snowfall indicator feature only applies to “sensor 1” which should be positioned outdoors
in an appropriate place but away from direct sunlight and rain to avoid inaccurate data
measurements.
HOW TO CHECK THE BAROMETRIC PRESSURE
The current and historical barometric pressure is shown on the atmospheric pressure window.
For monitoring the Sea Level barometric pressure reading at certain altitude, the user needs to select the local altitude
(-100 to 2500 meters or -330 to 8250 feet) for the altitude setting. Our weather station requires entry of elevation in
meters and in feet separately. Therefore, to convert feet to meters, multiply feet by 0.3048. To determine your
location elevation, please either contact your local library, TV/radio weather forecaster, or via Internet at
http://www.worldatlas.com/aatlas/infopage/elvation.htm.
1. To enter the altitude compensation setting mode, press ALT/PRESSURE button to switch from Barometric
Pressure to Altitude mode for 5 seconds.
