pressure is i ncreasing and the weather is expected to i mprove, but when indicator p oints
downwards, the air-pre ssure is dropping and the weat her is expected to become wor se.
Taking this i nto account, one can see how the weat her has changed and is expected to
change. For exampl e, if the indicator is pointing dow nwards together with cloud a nd sun
icons, then the last noticeable change in the weat her was when it was sunny (the sun icon
only). Therefore, the next change in the weather wi ll be cloud with rain icons sinc e the
indicator is pointi ng downwards.
Note:
Once the weather te ndency indicator has regi stered a change in air pressure, it wil l remain
permanently visuali zed on the LCD.
AIR PRESSURE H ISTORY (ELEC TRONIC B AROMETER WI TH BAROMETR IC
PRESSURE TR END)
The right side of t he second section of the LCD s hows the air pressure history bar gr aph.
The bar graph indicat es the air pressure history tre nd over the last 12 hours in 7 i ntervals: 0h,
-3h, -6h, -9h and -12h. T he “0h” represents the c urrent full hour air pressure recordi ng. The
columns represent t he “hPa” (0, ±1, ±3, ±5) at speci fic time. The “0” in the mi ddle of this scale
is equal to the curre nt pressure and each change (±1, ± 3, ±5) represents how high or low in
“hPa“ the past press ure was compared to the curre nt pressure.
If the bars are risi ng it means that the weather is getti ng better due to t he increase of air
pressure. If the bars go dow n, it means the ai r pressure has dropped and the weat her is
expected to get worse from t he present time “0 h“.
Note:
For accurate barometri c pressure trends, the weat her station should operate at t he
same altitude for recordings (i.e. it should not be moved fr om the ground to t he second
floor of the house). W hen the unit is moved to a new location, discard readings f or the
next 12 hours.
The level of the press ure bar will be affected by t he temperature change a nd it is for
reference only.
INDOOR TEMPE RATURE/HUM IDITY DAT A
The indoor temperat ure and humidity data are a utomatically updated and displ ayed on the
first secti on of the LCD.
OUTDOOR TEM PERATURE /HUMIDITY DA TA
The last LCD secti on shows the outdoor temperat ure and humidity, and t he reception
indicator.
If outdoor temperat ure/humidity data shows “--,-“, a ma nual search of the tra nsmitter can be
done : press and hold the MOD E key for 3 seco nds. The station will then start to search for a
transmitter.

ABOUT THE THER MO-HYGR O TRANSM ITTER
The range of the t hermo-hygro transmitter may be affected by the
temperature. At col d temperatures the transmi tting distance may be
decreased. Please bear thi s in mind when posi tioning the transmitters. Also the ba tteries may
be reduced in power for t he thermo-hygro transmi tter.
CHECKING FOR 868MHz RECEP TION
If the outdoor temperat ure and humidity data are not being received within three mi nutes after
setting up (or outdoor di splay always shows “- -.-” i n the outdoor section of t he weather
station during normal oper ation), please check t he following points:
1. The distance of the weat her station or transmi tters should be at least 2 meters away
from any interferi ng sources such as computer mo nitors or TV sets.
2. Avoid placi ng the transmitters onto or in the i mmediate proximi ty of metal window
frames.
3. Using other electri cal products such as headpho nes or speakers operating on the
868MHz-signal freq uency may prevent correct si gnal transmission or reception.
Neighbors using electri cal devices operating on t he 868MHz-signal frequency can al so
cause interference.
Note:
When the 868MHz signal i s received correctl y, do not re-open the battery cover of ei ther the
transmitter or weat her station, as the batteri es may spring free from the contacts a nd force a
false reset. Should t his happen accidentally then reset al l units (see “Setting up ” ab ove)
otherwise transmissi on problems may occur.
The transmissi on range is around 100 meters from t he thermo-hygro transmitt er to the
weather station (i n open space). However, this depe nds on the surrounding enviro nment and
interference levels. If no rec eption is possibl e despite the observation of these factor s, all
system units have to be rese t (see “Setting up ” above) .
POSITIONING THE WEATHE R STATION
The weather statio n must be place on a tabl e.
POSITIONING THE THERMO -HYGRO TRANSMITTER
Mounting at a shelter ed place. Avoid di rect rain and sunshine.
The thermo-hygro tra nsmitter can be placed o nto any flat surface or wall mount using the
bracket which doubles as a sta nd or wall mount base.
To wall mount:
1. Secure the bracket onto a desired wall using the screws a nd plastic anc hors.
2. Clip the transmitter o nto the bracket.
Note:
Before permanently fi xing the thermo-hygro to t he wall base, pace all units in the desired
locations to check t hat the outdoor temperature a nd humidity readings are receivabl e. In
event that the sig nal is not received, relocate t he thermo-hygro transmitter or t he weather
station sli ghtly as this may help the signal recepti on.
CARE AND M AINTENANCE
Extreme temperat ures, vibration and shock should be avoi ded as these may cause
damage to the unit and give i naccurate forecasts a nd readings.
When cleaning the displ ay and casings, use a soft damp cl oth only. Do not use
solvents or scouri ng agents as they may mark t he LCD and casings.
Do not submerge t he unit in water.
Immediately remove all low powered batteri es to avoid leakage and damage. Repl ace
only with new batteri es of the recommended type.
Do not make any repair at tempts to the uni t. Return them to their ori ginal point of
purchase for repair by a qualified engineer. Ope ning and tampering with the unit may
invalidate their guarantee.
Do not expose the units to extreme and sudde n temperature changes, this may l ead to
rapid changes in forecasts and readings and thereby red uce their accuracy.
