TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE
TRANSMITTER
The transmitter uses 2 x AA, IEC LR6, 1.5V batteries. To install and
replace the batteries, please follow the steps below:
1. Remove the cover.
2. Insert the batteries, observing the correct polarity (see marking
inside battery compartment).
3. Replace the batterycover on the unit.
Alkaline batteries are recommended for use in both units. Avoid
using rechargable batteries.
SETTING UP:
1. Insert the 2 x AA, IEC LR6, 1.5V batteries into the transmitter (See “To install and
replace batteries in the Temperature Transmitter” above).
2. Within 3 minutes, insert 2 x AA, IEC LR6, 1.5V batteries into the Weather wall clock as
indicated above (see "To install and replace batteries in the Weather wall clock“
above).
3. Once the batteries are in place, all segments of the LCD will light up briefly and a brief
beep sound will be hear. Then the indoor temperature “OF” and outdoor temperature - - -,
the time as 0:00, the date as 1/1, and weekday will be displayed.
4. Do not press any buttons for 10 minutes
5. The Weather wall clock will start receiving data from the transmitter. The remote
temperature will then be displayed on the Weather wall clock. If the outdoor temperature
is not displayed 90 seconds after inserting the batteries into the receiver, all batteries are
needed to be removed and wait for at least 1 minute for reset from step 1.
6. The DCF time code reception will automatically start. This takes typicallybetween 3 - 5
minutes in good conditions. This time period is an excellent opportunity to locate the
transmitter in suitable location outdoors. In order to ensure sufficient 868MHz
transmission however, this should under good conditions be no more than 100 meters
from where the Weather wall clock will be finally positioned (see notes on “Positioning”
and “868MHz Reception”).
7. If after 10 minutes the DCF time has not been received, use the SET key to enter into the
set mode and change either the time or date in order to activate the DCF reception. The
clock will then automatically attempt to receive the DCF time. When this is successful,

22
the received time will override the manually set time. The date is also updated with the
received time (Please refers to notes on “DCF Radio controlled time” and “Manual time
setting”).
Note:
In the event of changing batteries of the unit ensure that the batteries do not spring free from
the contacts. Always wait at least 1 minute after removing the batteries before reinserting,
otherwise start up and transmission problems may occur.
RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Weather wall clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig, which has a time deviation of less than
one second in one million years. The time is coded and transmitted from Mainflingen near
Frankfurt via frequencysignal DCF-77 (77.5 kHz) and has a transmitting range of
approximately1,500 km. Your radio-controlled Weather Station receives this signal and
converts it to show the precise time in summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal cases, there
should be no reception problems within a 1500km radius of Frankfurt.
Once the outdoor temperature is displayed on the Weather station, the DCF tower icon in the
clock display will start flashing in the upper left corner. This indicates that the clock has
detected that there is a radio signal present and is trying to receive it. When the time code is
received, the DCF tower becomes permanently lit and the time will be displayed.
Daily DCF reception is done at 02:00 and 03:00 every day. If the reception at 03:00 is not
successful, then at 04:00 and 05:00 and 06:00 there are other tries, until one is successful. If
the reception at 06:00 is still not successful, then the next trytakes place at 02:00 next day.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all,
then please take note of the following:
• Recommended distance to any interfering sources like computer monitors or TV sets is a
minimum of 1.5 - 2 metres.
• Within ferro-concrete rooms (basements, superstructures), the received signal is
naturally weakened. In extreme cases, please place the unit close to a window and/ or
point its front or back towards the Frankfurt transmitter.

THE WEATHER FORECASTING ICONS:
There are 3 weather icons on the middle section of LCD 2, which 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 icons 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 rain.
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. 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 first floor of a house), remove the
batteries and re-insert them after about 30 seconds. By doing this, the Weather Station will not

29
mistake the new location as being a possible change in air-pressure when really it is due to the
slight change of altitude. Again, disregard weather forecasts for the next 12 to 24 hours, as this
will allow time for operation at a constant altitude.
THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendency indicators (located on the
left and right hand side 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.
OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the weather wall clock every 4 seconds. The
weather wall clock will update the temperature display every 4 seconds.
The range of the outdoor temperature transmitter may be affected by the temperature. At cold
temperatures the transmitting distance may be decreased. Please bear this in mind when
positioning the transmitter. Also the batteries may be reduced in power during periods of
extreme cold temperatures.
868MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE
TRANSMITTER
The Weather wall clock will receive the temperature data within 4 seconds. If the temperature
data is not being received 2 minutes after setting up (or the display shows “- - -”), then please
check the following points:
1. The distance of the Weather wall clock or outdoor temperature transmitter should be at
least 2 meters away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.

30
3. Using other electrical products such as headphones or speakers operating on the same
signal frequency (868MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 868MHz signal frequency can also
cause interference.
Note:
When the 868 MHz signal is received correctly, do not re-open the battery cover of either the
outdoor temperature transmitter or Weather wall clock, 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 maximum transmission range is 100 meters from the outdoor temperature transmitter to
the Weather wall clock (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).
CHANGING THE DISPLAY UNIT (DATE, ALARM TIME AND SECONDS)
There are three possibe display units to view the date, alarm time and seconds. (Default unit :
Date)
To change the display unit:
1. Press the + key. The display should now show the alarm time.
2. Press the + key a second time and the displaywill now show the seconds.
3. Press the + key third time and the displaywill now show the date again.
POSITIONING
Before permanently mounting ensure that the weather wall clock is able to receive DCF signals
from the desired location. Also, extreme and sudden changes in temperature will decrease the
accuracy of the weather wall clock.
To achieve a true temperature reading, avoid mounting where direct sunlight can reach the
outdoor temperature transmitter. It is recommended to mount the outdoor temperature
transmitter on a North-facing wall or in any well shaded area. The maximum transmitting range
is 100 meters obstacles such as walls, concrete, and large metal objects can reduce the range.
Place both units in their desired location, and wait approximately 10 minutes before
permanently mounting to ensure that there is proper reception. The outdoor temperature

31
transmitter is not waterproof and should not be placed anywhere it will become submerged in
water or be directly in the rain.
POSITIONING THE WEATHER WALL CLOCK:
There are two possible ways to mount the weather wall clock:
• use of the foldout table stand, or
• wall mounting
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 wall clock, below the battery
compartment. Once the foldout table stand is extended, place the weather wall
clock in an appropriate location.
WALL MOUNTING
1) Using a straightedge, horizontally space at 70 mm three screw
positions on a wall.
2) Install three mounting screws (not included) into a wall within
transmission range—leaving approximately 5mm extended from the
wall.
3) Place the Weather wall clock onto the screws, using the hanging holes
on the backside. Gently pull the weather wall clock down to lock the
screws into place.
Note: Always ensure that the Weather wall clock locks onto the screws
before releasing.

32
POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER
The remote temperature transmitter can be placed onto any flat surface
or wall mounted 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 remote temperature transmitter onto the bracket.
Note:
The mounting surface can affect the transmission range. If, for instance,
the unit is attached to a piece of metal, it may then either reduce or
increase the transmitting range. For this reason, we recommend not to
place the unit on any metal surfaces
or in any position where a large metal or highly polished surface is in the immediate vicinity
(garage doors, double glazing, etc.). Before securing in place, please ensure that the
Temperature Station can receive the 868MHz signal from the temperature transmitter at the
positions that you wish to place them.
CARE AND MAINTENANCE:
• Avoid placing the units in areas prone to vibration and shock as these may cause
damage.
• Avoid areas where the units can be exposed to sudden changes in temperature, i.e.
direct sunlight, extreme cold and wet/moist conditions as these will lead to rapid changes
which reduces the accuracy of readings.
• When cleaning the LCD and casing, use a soft damp cloth only. Do not use solvents or
scouring agents.
• Do not submerge the units into water.

33
• Immediately remove all low powered batteries to avoid leakage and damage. Replace
only with new batteries of the recommended size.
• Do not make any repairs to the units. Please return it to the original point of purchase.
Opening and tampering with the units may invalidate the warranty.
