The polarity is incorrect if the red LED on
the mains adapter is off and
• the charge indicator is not working on
terminal devices with a charging
function (i.e. rechargeable batteries or
terminal devices with built-in
rechargeable battery) or
• the terminal device is not working
(terminal devices without charge
function).
In the above-mentioned cases the
polarity must be changed over
immediately.
CAUTION: The red LED of terminal
devices with an extremely low short-circuit
current (e.g. MP3 players) may also
illuminate if the polarity is incorrect! If the
connected terminal device is not working
properly, unplug mains adapter
immediately, check the polarity setting and
change it over if necessary.
