Congratulations on your purchase of this universal power supply
unit for notebooks and netbooks. This unit is distinguished by its
reliability, compact, lightweight design, uncompromising focus
on safety and superior effi ciency. Please read these instructions
carefully before use to ensure proper and safe operation. This
power supply unit has a series of integrated protection mea-
sures that ensure maximum safety. For example:
• Input overvoltage protection
• Input undervoltage protection
• Shutdown in case of short circuit
• Shutdown in case of overheating
• Overcurrent fuse
The following items are included:
• 1 x Power supply unit
• 1 x Power cable
• 7 x Notebook adapter plugs
• 1 x Operating instructions
Getting started
1. a)
Ensure that your notebook/netbook requires a power
supply of 19 volts (+/- 1 V).
The voltage specifi cations can usually be found on the original
power supply unit or in the user manual of your notebook/net-
book. If in doubt, consult the manufacturer.
Warning:
Your notebook/netbook may be damaged if it requires a different
voltage then that specifi ed. Do not connect the power supply
unit to your notebook if you have any doubts as to the required
voltage.
b)
Ensure that the total power consumption of the notebook/
netbook does not exceed the power supply unit’s rated output
capacity of 74 W. The required maximum current may not
exceed 3.9 A.
2.
The adaptor plugs included with the power supply unit cover
most common notebooks/netbooks from well-known manufac-
turers.
Please select the correct adapter using the plug on the original
power supply unit. You may want to check whether the adapter
fi ts into the notebook’s socket while the notebook is switched off
and the power supply unit is NOT connected. The plug should
slide into the socket easily and fi t securely without too much
play.
Warning:
Do not use force under any circumstances. This may damage
the notebook’s power socket or the adapter. You can fi nd a
comprehensive and current compatibility list at

3.
Connect the correct adapter to the power cable’s DC
connection line. This connection is protected against polarity
reversal; i.e. the adapter fi ts easily into the connection cable in
one position only. Therefore, it is extremely important that you
never attempt to forcibly insert the adaptor plug in the wrong
position, as this can lead to the polarity being reversed.
Warning:
If the polarity is reversed then the notebook may be damaged.
4.
First connect the power supply unit with the notebook/net-
book. Finally, plug the mains plug of the power cable into the
power outlet. Turn on the power supply unit using the sliding
switch on the side of the device by moving the switch into the
“ON”
position.
If you are not using the device, switch the ON / OFF switch to the
“OFF”
position. Doing so saves on energy costs and protects the
environment.
