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.
