Operation
Start-up
u
Note the mains voltage!
The voltage of the power source
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 (3)
The rapid-charging procedure is indicated by
flashing
of the
green
battery charge level in-
dicator
(3)
. 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".
Continuously illuminated green battery charge level
indicator (3)
Continuous lighting
of the battery charge in-
dicator
(3)
indicates that the battery is fully
charged or that the temperature of the battery
is not within the permitted charging temperat-
ure range, and cannot be charged for this reason. The bat-
tery is charged as soon as the permitted charging temperat-
ure range is reached.
When the battery is not inserted,
continuous lighting
of the
battery charge indicator
(3)
indicates that the mains plug is
inserted in the socket and that the battery charger is ready
for 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.
