•Mounting at a sheltered place. Avoid direct rain and
sunshine
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.

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.

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)
