Operation
Wall mounting
The charger can be used either free-standing (for use on a
desktop) or mounted on the wall.
When affixing to the wall: Drill two holes, leaving a clearance
as specified in the image.
To secure it, use round-head screws with a diameter of 5 mm
to max. 6.5 mm.
72 mm
Start-up
Note the mains voltage! The voltage of the power source
u
must match the voltage specified on the rating plate of
the charger. Chargers marked with 230 V can also be op-
erated with 220 V.
Charging process
The charging process begins as soon as the mains plug for
the charger is inserted into the mains socket and the battery
(1) is inserted into the charging slot (2).
Thanks to the intelligent charging process, the charge condi-
tion of the battery is automatically detected and then
charged up with the optimal charge current depending on
battery temperature and voltage.
In this way, the battery is treated with care and remains per-
manently fully charged when it is stored in the charger.
What the display elements mean
Flashing green battery charge level indicator (4)
The rapid-charging procedure is indicated by
flashing of the green battery charge level in-
dicator (4). The battery can be removed at any
time and used.
Note: The charging process is only possible when the tem-
perature of the battery is within the permitted charging tem-
perature range, see section "Technical data".
Once approx. 80% of the battery capacity has
been reached, the flashing of the green battery
80 %
charge indicator slows down. The rapid-char-
ging process is now completed. If the battery
1 609 92A 48Y | (02.05.2018)
remains in the charger, the charging process will be com-
pleted in the Long Life charging mode.
Continuously illuminated green battery charge level
indicator (4)
The continuous light of the green battery
charge level indicator (4) signals that the bat-
tery is fully charged.
The battery can then be removed for immediate use.
When there is no battery connected, the continuous light of
the battery charge level indicator (4) indicates that the
mains plug is plugged into the mains socket and that the
charger is ready to be used.
Continuously illuminated red battery charge level
indicator (3)
The continuous light of the red battery charge
level indicator (3) shows that the temperature
of the battery is outside of the permitted char-
ging temperature range, see section "Technical
data". The charging process begins as soon as the permitted
temperature range has been reached.
Flashing red battery charge level indicator (3)
The flashing light of the red battery charge
level indicator (3) signals that the charging
process has been interrupted by a different
fault, see section "Errors – causes and correct-
ive measures".

Practical advice
When the charger is used continuously, or for several con-
secutive charge cycles without interruption, the charger may
heat up. This is, however, harmless and does not indicate
that the charger has a technical defect.
