WEATHER FORECAST AND WEATHER
TENDENCY:
WEATHER FORECASTING ICONS:
The weather icons in the second section of LCD can be
displayed in any of the following combinations:
Sunny Cloudy with sunny intervals Rainy
For every sudden or significant change in the air pressure,
the weather icons will update accordingly to represent the
change in weather. If the icons do not change, then it
means either the air pressure has not changed or the
change has been too slow for the Weather station to
register. However, if the icon displayed is a sun or raining
cloud, there will be no change of icon if the weather gets
any better (with sunny icon) or worse (with rainy icon)
since the icons are already at their extremes.
The icons displayed forecasts the weather in terms of
getting better or worse and not necessarily sunny or rainy
as each icon indicates. For example, if the current weather
is cloudy and the rainy icon is displayed, it does not mean
that the product is faulty because it is not raining. It simply
means that the air pressure has dropped and the weather
is expected to get worse but not necessarily rainy.
Note:
After setting up, readings for weather forecasts should be
disregarded for the next 12-24 hours. This will allow
sufficient time for the Weather station to collect air
pressure data at a constant altitude and therefore result in
a more accurate forecast.
Common to weather forecasting, absolute accuracy
cannot be guaranteed. The weather forecasting feature is
estimated to have an accuracy level of about 75% due to
the varying areas the Weather station has been designed
for use. In areas that experience sudden changes in
weather (for example from sunny to rain), the Weather
station will be more accurate compared to use in areas
where the weather is stagnant most of the time (for
example mostly sunny).

If the weather station is moved to another location
significantly higher or lower than its initial standing point
(for example from the ground floor to the upper floors of a
house), discard the weather forecast for the next 12-24
hours. By 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 indicators (located on the left and right sides of
the weather icons). When the indicator points upwards, it
means that the air-pressure is increasing and the weather
is expected to improve, but when indicator 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.
INDOOR TEMPERATURE/HUMIDITY DATA
The indoor temperature and humidity data are
automatically updated and displayed on the fourth section
of the LCD.
OUTDOOR TEMPERATURE/HUMIDITY DATA
The last LCD section shows the outdoor temperature and
humidity, and the reception indicator.

LOW BATTERY INDICATOR
Low battery indicator is displayed on the LCD when the
batteries require changing.
ABOUT THE THERMO-HYGRO TRANSMITTER
The range of the thermo-hygro transmitter may be affected
by the temperature. At cold temperatures the transmitting
distance may be decreased. Please bear this in mind
when positioning the transmitters. Also the batteries may
be reduced in power for the thermo-hygro transmitter.
CHECKING FOR 915MHz RECEPTION
If the outdoor temperature and humidity data are not being
received within three minutes after setting up (or outdoor
display always show “- -.-” in the outdoor section of the
Weather station during normal operation), please check
the following points:
1. The distance of the weather station or transmitters
should be at least 5 to 6.5 feet (1.5 -2 meters) away
from any interfering sources such as computer
monitors or TV sets.
2. Avoid placing the transmitters onto or in the
immediate proximity of metal window frames.
3. Using other electrical products such as headphones
or speakers operating on the 915MHz-signal
Low battery
indicator
(transmitter)
11
frequency may prevent correct signal transmission
or reception.
4. Neighbors using electrical devices operating on the
915MHz-signal frequency can also cause
interference.
Note:
When the 915MHz 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 “Setting up” above) otherwise
transmission problems may occur.
The transmission range is around 330 feet (100 meters)
from the thermo-hygro 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 “Setting
up” above).
POSITIONING THE WEATHER STATION
The weather station provides the option of table standing
or wall mounting the unit. Before wall mounting, please
check that the outdoor data can be received from the
desired locations.
To wall mount:
1. Fix a screw (not supplied) into the
desired wall, leaving the head
extended out by about 5mm.
2. Place the weather station onto
the screw, using the hanging hole
on the backside. Gently pull the
weather station down to lock the
screw into place.
Foldout table stand:
The foldout table stand leg is located
on the backside. Pull the stand out
from the bottom center edge of the
weather station, below the battery
compartment. Once the foldout table
stand is extended, place the weather
station in an appropriate location.
12
POSITIONING THE THERMO-HYGRO
TRANSMITTER
Mounting at a sheltered place. Avoid direct
rain and sunshine.
The thermo-hygro transmitter can be placed
onto any flat surface or wall mount using the
bracket which doubles as a stand or wall
mount base.
To wall mount:
1. Secure the bracket onto a desired wall
using the screws and plastic anchors.
2. Clip the transmitter onto the bracket.
Note:
Before permanently fixing the thermo-hygro to
the wall base, pace all units in the desired
locations to check that the outdoor temperature
and humidity readings are receivable. In event that the
signal is not received, relocate the thermo-hygro
transmitter or the weather station slightly as this may help
the signal reception.
CARE AND MAINTENANCE:
Extreme temperatures, vibration and shock should
be avoided as these may cause damage to the units
and give inaccurate forecasts and readings.
When cleaning the display and casings, use a soft
damp cloth only. Do not use solvents or scouring
agents as they may mark the LCD and casings.
Do not submerge the units in water.
Immediately remove all low powered batteries to
avoid leakage and damage. Replace only with new
batteries of the recommended type.
Do not make any repair attempts to the units. Return
it to their original point of purchase for repair by a
qualified engineer. Opening and tampering with the
units may invalidate their guarantee.
Do not expose the units to extreme and sudden
temperature changes, this may lead to rapid
changes in forecasts and readings and thereby
reduce their accuracy.
