After a few seconds the LEDs 25%/75% and 50%/100% are flashing alternately.
This indicates that no rechargeable battery is connected and that the charger is
ready.Four LEDs on the charger indicate the charging status (25%, 50%, 75%
and 100%).Once the LED “100%” lights up, the battery is fully charged. Discon-
nect the battery from the charger.
Connect the power socket to an appropriate mains socket via the supplied power
cable. The Power LED lights up green when the charger is ready for operation.
Connect the rechargeable battery to be charged via its XH balancer plug with the
relevant jack of the charger. At that, observe the correct polarity of the XH plug.
When connecting, do not use excessive force; always use a socket matching the
jack. Only connect a single battery to the charger at a time. Always use only one
of the XH sockets at a time.
