QUICK SETUP
Step 1: Power up your weather station
Insert the AC/DC adaptor to any 120V AC household outlet. Then insert the DC jack to the back case of your
unit.
Take out the stand at the back case and insert it horizontally to the back case, then rotate it by 90 degree to
secure it to the back case.
Step 2: install batteries to your outdoor transmitter
Keep your weather station and wireless outdoor transmitter next to each other. Slide open the battery cover at
the back of your wireless outdoor transmitter, then insert 2 x AAA alkaline batteries to the battery compartment.
Make sure the Channel selector is at 1position. Replace the battery cover.
Remark : Make sure (Channel 1) is displayed under the outdoor temperature and humidity. You could
press / CHANNEL to select Channel 1.
Your weather station will receive data signal from the outdoor transmitter in few seconds. Then place your
outdoor transmitter in a dry and shaded area.

P. 3
Installing backup batteries to your weather station
Your weather station requires 3 “AAA” alkaline batteries to provide backup power to it in the event of a
temporary power interruption.
1. Place your unit face down on a flat surface.

settings of your unit. Press once to turn on the backlight for 5 seconds.
Remarks:
Keep in mind that your outdoor transmitter has a 180-ft open air transmission with no obstructions.
Actual transmission range will vary depending on what is in the path of the signal. Each obstruction (roof,
walls, floors, ceilings, thick trees, etc.) will effectively cut signal range in half.
Insert the holder to the bottom of the outdoor transmitter for desktop or insert it to the back of the
transmitter for wall mount purpose.

WEATHER FORECAST AND PRESSURE TREND INDICATOR
Your weather station has a built-in barometric sensor which measures the change of the air pressure over time.
Your weather station takes around 12 hours to gather and average air-pressure readings to provide a weather
forecast for next 12 hours.
WEATHER ICONS
There are five possible types of weather icons that will be displayed:
SUNNY
SUNNY AND CLOUDY
(PARTLY SUNNY)
CLOUDY

P. 6
RAINY
STORMY
FROST ALERT
Frost Alert Icon appears when outdoor
temperature is below +3°C
AIR PRESSURE TENDENCY INDICAOTRS
When the arrow appears, the air pressure is increasing, the weather is expected to improve.
When the arrow appears, the air pressure is decreasing, the weather is expected to become worse.
When the arrow appears, the air pressure change is stable.
Remarks: Moving your weather station from one floor of a building to another floor will affect the accuracy
of your weather station, which should operate at the same altitude all the time. If you move it to a new
location, it will take 12 hours to get stable and accurate again.
Our weather station provides next 12-hour weather forecast. It may not match with the current weather
condition outside.
TO DISPLAY AIR PRESSURE READOUT
Press and hold until the calendar display shows the air pressure readout in inHg. Press and hold
again to revert back to calendar display.
