7. Charging units
If you leave a battery in the unit, it will be trickle charged so that the battery does not discharge. If you do not
use the unit for some time, remove the plug from the power supply.
Because of the unit's high charging current (950 mA for AA and 500 mA for AAA), it should be used only for high-
quality rechargeable batteries >1000 mAh (AA) and >500 mAh (AAA). The M2X quick charger has four charging
circuits, which enable 1, 2, 3 or 4 batteries to be charged simultaneously. Mignon (AA) micro (AAA), NiCd (nickel
cadmium) and NiMH (nickel metal hydride) batteries can be charged. The unit has overload protection.
7.2 TL 4+4 Ultrafast Charger
If you are using the TL 4+4 Ultrafast Charger or a structurally identical charging unit, you must observe the fol-
lowing instructions:
■
Before using the unit for the first time, remove the coloured adhesive strip beside the magazine (if avail-
able) and connect the power cable with the charging unit and a mains socket.
■
Place 1 to 4 rechargeable batteries individually into the upper charger (check their polarity!).
■
Note the signals of the upper red LEDs. They indicate the charging process and the completion of
charging.
■
Remove the charged batteries. (The red light in question must be flashing!)

Charging station
LED red light: Batteries are being charged (quick charge)
LED flashing red light: Batteries are charged (trickle charge)
Note:
when battery is correctly loaded, the light will flash
once per second. Fast flashing (5 times a sec-
ond) indicates a faulty rechargeable battery or a
non-rechargeable battery.
Dock (prevents self-discharge)
You can find further information in the operating instructions.
7.3 Operation with alkaline batteries
The Mobil-O-Graph
®
can also be operated with alkaline manganese batteries. These batteries are not recharge-
able and must therefore not be placed in the charging unit.
Two alkaline batteries at full capacity have a higher voltage (min. 3.1 V) than 2 NiMH batteries (min. 2.75 V).
The battery indicator on the recorder will therefore also show a higher voltage.
Place these batteries in the battery compartment in the same way as the rechargeables (check polarity). After
24 hours remove the batteries and dispose of them.
Remember that batteries are special waste and must be disposed of separately from domestic refuse.
