Display „ERR" („ERROR") for one or several inserted batteries
• A non-rechargeable battery or impermissible battery was inserted accidentally.
• The wrong battery chemistry was selected
• The rechargeable battery is defective.
• If „ERR" is displayed at the same time for several cells, remove all cells from the charger
and charge the cells individually to detect the defective battery.
Immediate display „RDY" („READY") in programme „DIS" (DISCHARGE") or
immediate commencement of charging at programme „CHK") („CHECK")
• The inserted battery is deep-discharged. Therefore, the discharge process is cancelled
to protect the battery.
Low charge capacity (C) although the battery was discharged
• Process battery with the „ALV" („ALIVE") programme. If the charge capacity „C" is still too
low, the battery is defective.
No display in the device display and/or no reaction due to EMC impulses,
electrostatic discharge = ESD, surge impulses or line-conveyed interference
resistance
• Disconnect the charger from the mains for several seconds and reconnect it.
Significant warming on the casing
• The high performance of the device results in heating of the top and bottom of the
casing; this is no fault. Ensure good ventilation of the charger.
