SETTING UP:
Note: this temperature station can only receive one transmitter only.
1. First, insert the batteries to the transmitter (see “How to install and replace
batteries in the Temperature transmitter”below).
2. Within 30 seconds of powering up the transmitter, insert the batteries to 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. Following the indoor temperature, the time as 0:00 will be
displayed. If they are not shown in LCD after 60 seconds, remove the batteries and
wait for at least 60 seconds before reinserting them. Once the indoor data is
displayed user may proceed to the next step.

22
3. After the batteries are inserted, the Temperature Station will start receiving data
signal from the transmitter. The outdoor temperature should then be displayed on
the Temperature station. If this does not happen after 2 minutes, the batteries will
need to be removed from both units and reset from step 1.
4. In order to ensure sufficient 868 MHz transmission however, this should under
good conditions be a distance no more than 80 meters between the final position of
the Temperature Station and the transmitter (see notes on “Positioning” and “868
MHz Reception”).
HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION
The Temperature Station uses 2 x AA, IEC LR6, 1.5V
batteries. When batteries will need to be replaced, the
low battery icon will appear on the LCD. To install and
replace the batteries, please follow the steps below:
1. Lift up the battery compartment cover.
2. Insert batteries observing the correct polarity (see
marking).
3. Replace compartment cover.
NOTE: During a reset or battery change, it is
recommended to leave the station and sensor without powerfor 10 minutes.

23
HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE
TRANSMITTER The Temperature transmitter uses 2 x AAA, IEC LR3, 1.5V batteries.
When batteries will need to be replaced, the low battery icon will
appear on the LCD of the Temperature Station. To install and replace
the batteries, please follow the steps below:
1. Remove the battery compartment cover.
2. Insert the batteries, observing the correct polarity (see
marking).
3. Replace the battery holder to the unit.
Note:
In the event of changing batteries in any of the units, all units need to be reset by
following the setup procedures. This is because a random security code is assigned by
the transmitter at start-up and this code must be received and stored bythe Temperature
Station in the first few minutes of power supplying.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure
optimum accuracy of these units. (Battery life –see Specifications)

24
Please participate in the preservation of the environment. Return used batteries to
an authorized depot.

868 MHz RECEPTION CHECK
The Temperature Station should receive the outdoor temperature data within a few
minutes after setup. If the temperature data are not received about 2 minutes after setup
(the signal reception icon does not appear), 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.

29
2. Avoid positioning the Temperature 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 (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 868MHz signal is received correctly, do not re-open the battery cover of either
the transmitter or the Temperature Station, as the batteries may spring free from the
contacts and force a false reset. If this happens accidentally, all units must be reset (see
Setting up above) otherwise transmission problems may occur.
The transmission range is about 80 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 theobservation of these factors, all system units
have to be reset (see Setting up above).
POSITIONING THE TEMPERATURE STATION:
Table standing

30
The Temperature Station comes attached with a table stand, which
provides the option of table standing the unit in addition to wall
mounting.
To wall mount:
Before wall mounting, please check that the outdoor temperature values
can be received from the desired locations:
1. Fix a screw (not supplied) into the desired wall, leaving the head
extended out by about 5mm.
2. Hang the Temperature Station onto the screw. Remember to
ensure that it locks into place before releasing.
POSITIONING THE REMOTE 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.

31
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 anyposition 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:

32
•Extreme temperatures, vibrations and shocks should be avoided as these may
cause damage to the unit 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. Furthermore, fix all parts in place where the
units are adequatelyprotected against moisture and rain.
•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 them to their original point of
purchase for repair by a qualified engineer. Opening and tampering with the unit
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.
