AKG Acoustics CU400 Battery Charger User Manual


 
4 Charging
1. You may safely remove the transmitter at any time before the charging cycle is com-
pleted.
2. You may safely charge the battery inside the transmitter at any time, even before the bat-
tery is completely discharged.
3. At ambient temperatures above +40°C, the charger may overheat. As a result, the charg-
ing cycle may take considerably longer or stop altogether (STATUS LED flashing red).
As soon as the ambient temperature drops below +40°C, the charging cycle will be re-
sumed automatically (STATUS LED will be lit red).
4. If the battery heats up to more than +60°C during a charging cycle (e.g., due to high
ambient temperature), the charging cycle will be stopped automatically (STATUS LED
flashing red). Most batteries will be unusable after being heated up to more than +60°C.
5. Excessive vibrations may cause the charging cycle to be stopped (STATUS LED flashing
red), restarted (STATUS LED is lit orange), or appear completed (STATUS LED lit green)
ahead of time. Make sure the charger will not be subjected to vibrations during the
charging cycle and will rest firmly on a hard surface.
6. Items 1 and 2 above notwithstanding, if you wish to extend the useful life of recharge-
able batteries be sure to
completely discharge the battery every time, i.e., not to charge the battery before the
battery warning appears on the transmitter display;
charge the battery fully every time, i.e., not to remove it from the charger before the
charging cycle is completed;
avoid charging batteries at temperatures below +5°C or above +40°C. At these
temperatures, the charging cycle will not start and the STATUS LED will be lit orange.
The charging cycle will be resumed automatically as soon as the battery tempera-
ture returns to the acceptable range.
use no batteries other than the rechargeable types recommended in section 7 Spec-
ifications.
7. Rechargeable batteries will only reach their full capacity after several charging cycles.
8. If you insert a transmitter with a dry battery into the charger, the charging cycle will be
stopped immediately after the battery test and a few minutes of charging. The STATUS
LED will start flashing red.
Although there is virtually no risk of damaging the transmitter or charger, it is good prac-
tice not to insert transmitters using dry batteries into the charger.
