4. Possible sources of interference
I
nterferences as with a radio transmitter can occur and could be
caused by the following influences:
• In buildings with a lot of concrete, metal parts and electrical
systems, reception problems can occur (e.g. Mall).
• Electrical devices such as television, computer, house-hold
devices, etc. or transformers, land lines, radio transmitters
and railways are possible direct sources of interference.
• Atmospheric influences and geographical features (moun-
tains, etc.) can affect the propagation of the radio waves.
• The distance from the transmitter does also influence the
reception. Areas such as Southern Italy or Northern Scandi-
navia are also critical areas because of the great distances
from the transmitter.
• In all regions, so-called “dead spots” can occur making
reception impossible.
• Weak batteries in the device decrease the quality of recep-
tion.
5. Commissioning and configuration
Inserting batteries/Changing batteries
• Open the battery compartment at the rear of the weather
station and insert the three batteries (LR6/ Mignon/ AA),
ensuring proper polarity, into the battery compartment.
When disposing of dead batteries, see note on the disposal
information.
Note!
All internal data is deleted when you change the batteries. The
configuration parameters (weather region, time zone and contrast)
must be entered again (see the following chapter). Receiving all
weather data requires a period of at least 24 hours.
Calling up the configuration menu
• Press the <SET> button for at least three seconds. The first
point in the configuration menu (weather region) is called
up.
