First, insert the batteries into the Temperature Station (see “How to install
and replace batteries in the Temperature Station” below). Once the
batteries are in place, all segments of the LCD will light up briefly and a short
signal tone will sound. Then the indoor temperature, the time as 0:00 and the
date as 1.1. will be displayed. If the indoor temperature is not displayed after
a few seconds, remove the batteries and wait for at least 10 seconds before
reinserting them. Once the indoor data is displayed proceed to step 2.
Within 3 minutes of activating the Temperature Station, place the batteries
into the Temperature Transmitter (see “How to install and replace batteries
in the Temperature Transmitter” below).
After inserting the batteries into the transmitter, the Temperature Station will
start receiving transmissions from the transmitter. The outdoor temperature
should then be displayed on the Temperature Station. If this does not
happen within 15 minutes, the batteries will need to be removed from both
units and reset from step 1.
The Temperature Station can take up to 3 remote transmitters. If you have
purchased additional transmitters, follow step 2 for all extra transmitters.
However, ensure that you leave 10 seconds in between the reception of the
last transmitter and the set-up of the following transmitter. The Temperature
Station will number the transmitters in the order of set-up, i.e. the first
transmitter will have the temperature displayed with the number 1 against it
and so on.
When all the transmitters are set up, there is a testing period, during which
the display switches quickly between all the received transmitters at random,
according to which random transmission it receives. Pressing any key will
stop this process and the display will show the temperature for the first
transmitter. The process also stops automatically if no keys are pressed for a
few minutes.
Once the remote temperature has been received and is displayed on the
Temperature Station, the DCF-77 time code reception is automatically

7.

started. This takes typically between 3-5 minutes in good conditions. This
time period is an excellent opportunity to locate the transmitter(s) in suitable
location(s) outdoors. In order to ensure sufficient 433 MHz transmission
however, this should under good conditions be no more than 20 - 25 metres
from where the Temperature Station will be finally positioned (see notes on
“Positioning” and “433 MHz Reception check”).
If after 10 minutes the DCF time has not been received, use the SET key to
manually enter a time initially. The clock will automatically attempt each hour
to receive the DCF time. When this is successful, the received time will
override the manually set time. The date is also updated with the received
time (Please refer also to notes on “Radio controlled time” and “Manual
time setting”).

HOW TO INSTALL AND REPLACE BATTERIES IN THE
TEMPERATURE STATION
The Temperature Station uses 2 x AA, IEC LR6,
1.5V batteries. When batteries need to be replaced,
the battery symbol will appear on the LCD. To install
and replace the batteries, please follow the steps
below:
1. Insert finger or other solid object in the space at
the bottom centre of the battery compartment
and lift up to remove the cover.
2. Insert batteries observing the correct polarity
(see marking).
3. Replace compartment cover.

HOW TO INSTALL AND REPLACE BATTERIES IN THE
TEMPERATURE TRANSMITTER
The transmitter uses 2 x AAA, IEC, LR3, 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).
3.
Replace the battery cover on the unit.
Note:
In the event of changing batteries in any of the units, all units need to be reset by
following the setting up procedures. This is because a random security code is
assigned by the transmitter at start-up and this code must be received and stored
by the Temperature station in the first 3 minutes of power being supplied to it.

BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure
optimum accuracy of these units.
Please participate in the preservation of the environment. Return
used batteries to an authorised depot.

LCD SCREEN AND SETTINGS
DCF Tower Icon (for
time reception)

Time

For better distinctness the LCD screen is split into 4 sections displaying the
informations for time, date, indoors and outdoors.

LCD 1 RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Atomic 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 frequency signal DCF-77 (77.5 kHz)
and has a transmitting range of approximately 1,500 km. Your radio-controlled
Temperature 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 Temperature 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.
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.
During nighttime, the atmospheric disturbances are usually less severe - the
reception is possible in most cases. A single daily reception is adequate to
keep the accuracy deviation below 1 second.

MANUAL TIME SETTING:

TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the Temperature Station
approximately every 60 seconds.

The range 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 positioning the transmitter. Also the batteries may be reduced in power.

433 MHz RECEPTION CHECK
The Temperature station will receive the temperature data within 15 minutes. If the
temperature data is not being received 15 minutes after setting up (the display
shows “- - -”), then please check the following points:
1.
The distance of the Temperature Station or transmitter should be at least 1.5
to 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.
3.
Using other electrical products such as headphones or speakers operating
on the same signal frequency (433MHz) may prevent correct signal
transmission and reception.
4.
Neighbours using electrical devices operating on the 433MHz signal
frequency can also cause interference.
Note:
When the 433 MHz signal is received correctly, do not re-open the battery cover of
either the transmitter or Temperature 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 20 - 25 m from the transmitter to the
Temperature 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).

POSITIONING THE TEMPERATURE STATION:
The Temperature station comes attached with a removable table stand, which
provides the option of table standing or wall mounting the unit.
Before wall mounting, please check that the outdoor
temperature(s) can be received from the desired location(s). To
wall mount:
1.
Fix a screw (not supplied) into the desired wall, leaving the
head extended out the by about 5mm.
2.
Remove the stand from the Temperature station by pulling it
away from the base and hang the station onto the screw.
Remember to ensure that it locks into place before releasing.

POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER
The Temperature Transmitter is supplied with a holder that may
be attached to a wall with the three screws supplied. To attach
to the wall, please follow the steps below:
1.
Mark the wall using a pen through the holes in the holder
to obtain the exact drilling position.
2.
Drill holes in the wall at the points marked.
3.
Screw holder onto wall.
There is also double sided tape included with the wall mount. On smooth surfaces
this can be used instead of drilling holes. The mounting surface can, however,
affect the transmission range. If for example 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 placing the unit on any metal surfaces or in any position where a
large metal or highly polished surface is in the immediate proximity (garage doors,
double glazing, etc.). Before securing in place, please ensure that the Temperature
Station can receive the 433 MHz signal from the Temperature Transmitter at the
positions that you wish to situate them.
The Temperature Transmitter simply clicks in or out of the holder. When inserting or
removing the Temperature Transmitter to or from the wall holder please hold both
units securely.

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 displays and casings, use a soft damp cloth only. Do not
use solvents or scouring agents as they may mark the LCD and casing.
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 unit. Return it to its original point of
purchase for repair by a qualified engineer. Opening and tampering with the
unit may invalidate its guarantee.
Do not expose the unit to extreme and sudden temperature changes, as this
may lead to rapid changes in forecasts and readings and thereby reduce its
accuracy.
