No function or no display
• Has the round connector of the power adapter be inserted into the socket on the charger?
• Is the power adapter correctly inserted into the mains socket, is mains voltage available?
The inserted battery is not recognised ("null" on the display)
• The battery contacts are oxidised/highly resistive. Clean the battery contacts.
• The battery has discharged deeply or is faulty.
• Check whether the battery has been inserted correctly; try a different battery slot as a test.
After the charging process, the battery runs flat again quickly when used
• Use a lower charging current. Depending on the battery quality, the charger may end the
charging process at a high charging current, even though the battery is not full. Note the
battery manufacturer's instructions, if applicable.
• The battery has aged.
• With NiCd batteries, there may be a memory effect in partially discharged batteries. This
causes the battery to lose capacity. Use the "CHARGE TEST" operating mode for the battery.
Here, the battery is first charged, then discharged and finally recharged again.
The displayed capacity is too low.
• The battery was not completely empty before charging.
• Use a lower charging current. Depending on the battery quality, the charger may end the
charging process at a high charging current, even though the battery is not full.
The battery gets warm during charging or discharging
• This is normal, especially when using higher charging/discharging currents.
The display illumination is off
• The display illumination automatically goes out after several seconds. It comes back on when
a key is pressed.
