If no accumulator is inserted, you can turn on the POWER mode. The display contrast can be
changed at any time (also during charging).
Charge Programs
- CHARGE = charge respectively recharge once only .
CHAR (CHARGE) means that the inserted accumulator is charged.
- DISCHARGE = discharge only once
DISCHARGE means that the inserted accumulator is discharged only.
- CHK (CHECK) = discharge once and recharge
- CHECK means that the inserted accumulator is discharged and charged again.
- CYC (CYCLE) = charge / discharge / charge
CYCLE means that the inserted accumulator is first charged, then discharged and finally
charged again.
- ALV (ALIVE) = charge / discharge / charge / discharge / charge
The ALIVE program serves to revive new accumulators stored over a longer period of time.
If an accumulator is already treated in slot 1, the selection starts with the same program as this
accumulator (SAME AS SLOT 1); otherwise the selection starts with CHARGE.
Please note that new and possibly improperly treated accumulators may at first only take up
30% of their capacity. This bad degree of effectiveness is indicated by a high charge capacity
(C)and a very low discharge capacity (D). Charge these accumulators with the ALIVE program.
After some cycles, the usable capacity (D) increases.
NiCd and NiMH accumulators should be charged with C/3 up to 1C.
Accumulator Voltage
The accumulator voltage is stated in the deactivated state (and can therefore not be measured
during operation). If no voltage U is displayed, the charger hasn't determined it yet.
Accumulator Status
In order to obtain a fast overview of the status of the accumulator to be charged respectively
discharged, this device displays a battery symbol. This symbol merely serves to be able to tell
at a quick glance how far the charge respectively discharge process has already advanced.
Here, the battery symbol is filled from the bottom to the top during charging, while it is emptied
from the top to the bottom when discharging. This does not allow any conclusions about the
time remaining until the end of the program. When the charge status of the accumulator was
not determined yet, a question mark appears in place of the battery symbol (in this manual, the
battery symbol is generally portrayed with a "?".
Charge and Discharge Current
The current I flowing through the accumulator during charging and discharging is displayed. If
no current was determined at the start of a program or if there is no current running after the
end of the program (READY/ERROR), I = 0.000 A appears.
Times
The complete time in which the accumulator was charged and discharged is displayed in hours
and minutes (TIME hh:mm). The time during trickle charge (TRICKLE) and during breaks
(BREAK) is not added.
If an accumulator exceeds approx. 80% of its maximum capacity during charging, a part of the
charge current is converted to heat. This may cause the accumulator to heat up.

Now you can take out the accumulator.
If you leave the accumulator in the charger and if required for the accumulator, the trickle
charge program TRICKLE (TRI) is started automatically. This means that the accumulator is
recharged (this naturally does not apply if the accumulator was merely discharged with the pro-
gram DISCHARGE). The capacity (C) of the trickle charge and the time required for this
(hh:mm) is not displayed or added. Only the voltage and the current are constantly updated.
Therefore, the charge capacity, the discharge capacity and time only always refers to the
processed program.

If the 16 A total charge current were already reached, each additional accumulator is set to

ished.

This charger has a memory backup, meaning that the program and the added capacity values
of the accumulator are saved in case of a power failure. Therefore never change the accumula-
tor when the charger is off, as it otherwise takes over the no longer valid values and would thus
determine wrong values for the new accumulator!
If the charger is turned off during program selection, selection starts anew.
The programs can only be continued if the integrated gold cap was previously charged (this
requires that the charger was turned on for at least two hours).
ATTENTION!
All inserted round cell accumulators must be fast-charge capable in POWER mode.
Please note that the inserted micro accumulators have to have a minimum nominal
capacity of 700 mAh, MIGNON min. 2000 mAh and BABY accumulators at least 4000 mAh
in POWER MODE!
