Before use
Setting up the devices
First install the batteries in the outdoor sensor.
Failure to observe the following warnings can result
in injuries or property damage.
When choosing where to position the weather station, make sure that it is not
exposed to direct sunlight, vibrations, dust, heat, cold or moisture. Do not place
the devices close to sources of heat, e.g. radiators. Otherwise they may be
damaged.
Do not place the devices on valuable or sensitive surfaces unless these are
appropriately protected. Otherwise they may be damaged.
Please ensure that neighboring devices are not operated at the same frequency
of 433 MHz. These types of devices may interfere with the radio connection.
Use the included drill template (shown on the fold-out page) intended for mark-
ing drill holes.
Preparing the weather station for use
Removing the battery insulation strip:
Open the battery compartment 40 on the back of the weather station.
Remove the battery insulation strip.
Then close the battery compartment.
As soon as the battery insulation strip has been removed the weather station will
start receiving radio signal.
Note: Do not move the weather station while it is receiving the signal. This may
disrupt reception.
Connecting the weather station with the outdoor sensor and the
WWVB radio signal:
After removing the battery insulation strip the weather station will attempt to establish
a connection with the outdoor sensor. This process can take a few minutes. The
symbol will keep flashing for a few minutes. After successfully connecting with the
outdoor sensor, the selected channel symbol
the channel of the outdoor sensor (if necessary you can change the channel of the
outdoor sensor as shown under “Setting the channel”). If the connection with the outdoor sensor is not established automatically, this can be done manually as follows:
1. Press the channel button (CH)
37
. The icon of the selected channel27 will flash
in the LC display.
2. Then press the sensor RESET button
43
.
As soon as the weather station has established a connection with the outdoor sensor
it automatically begins to receive the WWVB radio signal. This process takes several
minutes and is indicated in the LC display by a flashing radio tower symbol
5
.
When the WWVB radio signal is being successfully received, the radio tower symbol
is shown permanently in the display. If the product cannot synchronize with the atomic
clock during setup, you can also set the clock manually (“Setting the 12 / 24 Hour
mode / °C / °F / hPa / inHg / Time zone / time / date / language manually”).
Radio signal (WWVB):
The WWVB signal (time signal transmitter) consists of time pulses emitted by one of
the most accurate clocks in the world close to Fort Collins, Colorado.
Reception of the radio signal generally takes 3–10 minutes.
Reception can be considerably impaired by obstacles (e.g. concrete walls) or sources
of interference (e.g. other electrical devices). In the event of reception problems,
change the position of the weather station (e.g. to somewhere near a window).
After connecting with the outdoor sensor or 3 minutes after the battery insulation
strip is removed, the weather station automatically begins to search for the WWVB
radio signal. The LC display will show a flashing radio tower symbol
process.
Note: In buildings made of reinforced concrete the reception of the radio signal
may be severely impaired (see “Setting up the devices”).
In order to correct any deviations from the exact time, the clock is automatically
synchronized with the WWVB radio signal every day at 1:00, 2:00 and 3:00.
The weather station’s reception of the WWVB radio signal can also be initiated
manually.
Press the + and – button 35, 36 at the same time. The weather station attempts
to receive the WWVB radio signal. This process takes several minutes and is indicated in the LC display by a flashing radio tower symbol.
If the connection with the WWVB radio signal cannot be established, the search is
stopped.
Note: If the clock of the weather station cannot receive the WWVB radio signal due
to errors, the distance to the transmitter or similar reasons, the time may also be set
manually. If reception of the WWVB signal is successful, the manual settings are
overwritten.
Setting the 12 / 24 Hour Mode / °C / °F / hPa / inHg /
