3. Safety Instructions
Transportable world receivers are used in a
wide range of climate zones. Particularly
when outdoors, make certain that ...
•the environmental limits are not excee-
ded (see Section 2).
•Electronic devices can be damaged by
moisture.
•Extremely dry air can cause static char-
ges that can lead to faulty functions.
•Excessive temperatures (e.g. direct sun-
light) or very low temperatures (e.g. out-
doors in winter) can permanently darken
the liquid crystal display.
Transportable devices are particularly at
risk to accidental damage. You can reduce
this risk by observing the following:
•Protect the device against heavy stres-
ses, such as impacts and falls.
•Select a location in your travel luggage
where it cannot be damaged or swit-
ched on by other hard objects.
•When in areas with elevated security
requirements (e.g. airplanes), it is best
to transport the device without the bat-
teries inserted because it cannot be
completely switched off (clock, timer
functions, ...).

b) External Power Supply
Connect an external power supply of
DC 6...7.5V / 300 mA to the power sup-
ply jack, as seen in the picture.
Note: The station memory described in
Section 7 will be deleted if the device is
without power for longer than about 30
seconds.
You should therefore leave an external
power supply connected while you change
the batteries – or finish changing them wit-
hin 30 seconds!
4. Power Supply
Important: Make certain that the polarity is
correct – both for the batteries as well as
for the external power supply. If the polarity
is reversed, the device will be damaged.
a) About the Batteries
•Open the battery compartment on the
back side of the device and insert four
batteries of type "1.5V AA" according to
the labels in the battery compartment.
Note: Used batteries may not be dispo-
sed of in household waste. Return these
to your retailer or to an appropriate col-
lection site for disposal.
