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
rear 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 disposed
of in household waste. Return these to
your retailer or to an appropriate collection
site for disposal. Remove all batteries from
the battery compartment if you are not
planning to use the device for a longer
period. The device can be irreparably
damaged by leaking battery acids.
Transportable devices are particularly
at risk of accidental damage. You can
reduce this risk by paying attention to
the following:
ƽ Protect the device against heavy
stresses, such as impacts and falls.
ƽ Select a location in your travel luggage
where it cannot be damaged or switched
on by other hard objects.
ƽ When in areas with elevated security
requirements (e.g. airplanes), it is best
to transport the device without the
batteries inserted because it cannot be
completely switched off (clock, timer
functions, ...).
