• Use the MODE button (1) to select a charging mode. Press the button until the LED/LEDs indicate the desired
function (6 V or 12 V mode). For details on individual charging modes, refer to the next section ("b) Charging
modes and functions").
Connect the adapter cable to the battery. Never connect the cable directly to other devices!
• Connect the charger to the battery. Ensure that the battery is connected in the correct polarity. The red adapter ca-
ble must be connected to the positive terminal, and the black adapter cable must be connected to the negative ter-
minal. Connect the cables on the red and black clamps to the battery terminals. Screw the eyelet connector to the
terminal contacts (red and black terminal and eyelet connector: black = negative terminal, red = positive terminal).
For built-in batteries connected to an on-board system, connect the positive terminal and then connect the
black terminal to an earth potential (chassis) that is positioned at a slight distance from the battery and the
fuel pipe. Check that the clamps are connected properly.
• Disconnect all devices from the battery. If the battery is mounted inside a vehicle, switch off the ignition and other
connected devices.
For more information on charging vehicle batteries, follow the instructions and safety information in the
owner's manual. Modern vehicles are equipped with sensitive electronic components and sensors which
may be damaged if you do not exercise caution.
• The LED (5) will turn on if the polarity is incorrect. Check the polarity and connect the terminals in the correct
polarity.
• If the charging circuit is short-circuited, the defective LED indicator (5) will turn on.
• The charger can automatically detect defective batteries. If the battery is defective, the selected charging program
will not be started and the defective LED indicator (5) will turn on. Ask a technician to inspect the battery, or
purchase a replacement.
• Disconnect the battery and the charger from the power supply after the battery has nished charging. Disconnect
the mains plug (6) from the mains socket. Remove the black and then the red clamp from the battery.
b) Charging modes and functions
11. 6 V motorcycle mode (7.2 V ±0.25 V)
• This mode is designed for 6 V batteries with capacity of less than 24 Ah, e.g. 6 V motorcycle batteries.
• To select this mode, press the MODE button (5) until the 6 V LED indicator (4) turns on. The charging process will
start automatically (1 A ±10 %). The charging LED (2) will start to ash.
• The charging indicator (2) will stay constant when the battery is fully charged (7.2 V ±0.25 V). The device will
switch off automatically.
22. 12 V car mode (14.4 ±0.25 V)
• This mode is designed for 12 V batteries with capacity of less than 24 Ah, e.g. 12 V car batteries.
• To select this mode, press the MODE button (5) until the 12 V LED indicator (3) turns on. The charging process
will start automatically (1 A ±10 %). The charging LED (2) will start to ash.
• The charging indicator (2) will stay constant when the battery is fully charged (14.4 V ±0.25 V). The device
automatically switches to trickle charge mode.
