doing this, the Weather Station will not mistake the new location as being a possible change in air-pressure when really 
it is due to the slight change of altitude. 

 

WEATHER TENDENCY INDICATOR 

Working together with the weather icons is the weather tendency indicator (located on the left of the weather icons). 
When the arrow points upwards, it means that the air pressure is increasing and the weather is expected to improve, 
but when arrow points downwards, the air pressure is dropping and the weather is expected to become worse. 
Taking this into account, one can see how the weather has changed and is expected to change. For example, if the 
indicator is pointing downwards together with cloud and sun icons, then the last noticeable change in the weather was 
when it was sunny (the sun icon only). Therefore, the next change in the weather will be cloud with rain icons since the 
indicator is pointing downwards. 

 

Note:  

Once the weather tendency indicator has registered a change in air pressure, it will remain permanently 

visualized on the LCD. 

 
 
 

AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC PRESSURE TREND) 

The bottom right section of the LCD shows the air pressure history bar graph. 

 

 
 
 
 
 
 

 
 
 
 
 

The bar graph indicates the air pressure history trend over the last 12 hours in 5 intervals: 0h,      -3h, -6h, -9h and -

12h. The “0h” represents the current full hour air pressure recording. The left column shows the unit in “inHg” (0, ±0.03, 
±0.09, ±0.15). The “0” in the middle of this scale is equal to th

e current pressure and each change (±0.03, ±0.09, ±0.15) 

represents how high or low, in “inHg” scale, the past pre

ssure was compared to the current pressure. 

If the bars are rising it means that the weather is getting better due to the increase of air pressure. If the bars go down, 

it means the air pressure has dropped and the weather is expected to get worse from the present time “0h“.

 

 

 

Note: 

x

 

The level of the pressure bars will be affected by the temperature change. The reading is for the reference only.

 

x

 

For accurate barometric pressure trends, the weather station should operate at the same altitude for recordings 
(i.e. it should not be moved from the ground to the second floor of the house). When the unit is moved to a new 
location, discard readings for the next 48 hours. 

 
DISPLAY OF INDOOR TEMPERATURE 

The indoor temperature is measured automatically and displayed on the upper left corner of the LCD. 

 

 
 
 

 

 
 
DISPLAY OF OUTDOOR TEMPERATURE 

The upper right of the LCD section shows the outdoor temperature and a reception symbol.

 

 
 
 
 
 

 

 
DISPLAY OF INDOOR/OUTDOOR MAXIMUM AND MINIMUM RECORDS 

Press the 

MIN/MAX 

key several times to view the MIN/MAX indoor temperature, and MIN/MAX outdoor temperature 

sequentially. Date and time of recordings will be shown for outdoor data. 

 

 
RESETTING THE MAXIMUM/MINIMUM RECORDS 

To reset the MIN/MAX records, press and hold the 

MIN/MAX

 key for 2 seconds. This will reset 

ALL 

minimum and 

maximum temperature records to current readings. 

DISPLAY OF SUN DURATION TIME  

1. In 

normal 

date 

mode, 

press 

the 

SUN

 key twice to display the sun duration time (total number of hours of sunlight 

on the day).

 

2. Press 

the 

SUN

 

key again will display the selected city. (See “

LOCATION SETTNG FOR SUNRISE/SUNSET 

TIME”)

 

3. Press 

the 

SUN

 key again to go back to normal date display.  

 

THE MOON PHASE ICONS  

The weather station displays 8 different moon phase icons. The current moon phase is indicated with a bar segment 
according to the set calendar.  

 
 
 
 
 
 

 

LOW BATTERY INDICATORS  

Low battery indicator will show on the LCD when the batteries of weather station or transmitter require changing. 

 

TEMPERATURE TRANSMITTER 

The reception distance of the temperature transmitter may be affected by the temperature. At cold temperatures the 
transmitting distance may be decreased. Please bear this in mind when placing the transmitter. 

 

915 MHz RECEPTION 

The weather station should receive the temperature data within 80 seconds after set-up.

 

If the temperature data is not 

received 80 seconds after setting up (the outdoor tempe

rature shows “

- - -

”)

, please check the following points: 

1. 

The distance of the weather station or transmitter should be at least 5 to 6.5 feet (2 

3 meters) away from any 

interfering sources such as computer monitors or TV sets. 

2. 

Avoid positioning the weather station onto or in the immediate proximity of metal window frames. 

3. 

Using other electrical products such as headphones or speakers operating on the same signal frequency (915 
MHz) may prevent correct signal transmission and reception. 

4. 

Neighbors using electrical devices operating on the 915 MHz signal frequency can also cause interference. 

 

 

 

Note:

 

When the 915 MHz signal is received correctly, do not re-open the battery cover of either the transmitter or weather 
station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then 
reset all units (see 

Initial set up

 above) otherwise transmission problems may occur. 

The transmission range is about 330 feet / 100 meters from the transmitter to the weather station (in open space). 
However, this depends on the surrounding environment and interference levels. If no reception is possible despite the 
observation of these factors, all system units have to be reset (see 

Initial set up

). 

 

 

 

POSITIONING 

 

WEATHER STATION: 

 

The weather station comes complete with a foldout stand that gives the option of table standing or 
wall mounting. 

 
 
 
 
 
 
 

 

To wall mount: 

1. 

Fix a screw into the desired wall, leaving the head extended out by about 0.2” (5mm).

 

2. 

Using the weather station hanging hole, carefully hang it onto the screw. 

 

Note:

 

Always ensures that the unit locks onto the screw head before releasing.
