a full charge. The clamp icon and battery icon with four bars light solid, and the arrow icons will gradually and repeatedly move
downward to the battery icon. In this mode, the unit monitors the battery voltage and charges as necessary to assure the battery
maintains full capacity. The unit remains in float charge mode as long as the charger is connected to the battery and plugged into a
functioning AC outlet.
When disconnecting charger, disconnect the AC cord, remove clamp from vehicle chassis, and then remove clamp from battery terminal.
Checking the Battery Voltage
TO CHECK THE BATTERY VOLTAGE IN STANDBY MODE
1. Set up the battery charger and connect to the battery following steps 1 through 2 in the “Charging the Battery” section.
2. Press the battery voltage check button. The LCD screen will display the following:
The digital display shows the current voltage of the connected battery for 10 seconds. During this period, pressing the battery voltage
check button again will return the unit to standby mode. The gage without the pointer will light solid. The unit will automatically
return to standby mode after 10 seconds.
TO CHECK THE BATTERY VOLTAGE IN CHARGING MODE:
Press the battery voltage check button and the LCD screen will display the following:
The digital display shows the current voltage of the connected battery for 10 seconds. During this period, pressing the battery voltage
check button again will return the unit to charging mode. Pressing the alternator check button or the battery recondition button will

Unplug the charger; then remove the clamps. Reconnect the clamps properly.
3. When the unit is properly connected, press the battery charge button on the control panel. The LCD screen will display the following:
The digital display shows the output current that is charging the battery. The gauge indicates the charge status of the battery. The
clamp icons and the battery icon light solid, the bars on the battery icon will change from empty to solid (bottom to top) repeatedly
and the arrow icons will gradually and repeatedly move downward to the battery icon.
Notes: The “ ” icon will appear at the top right of the gauge section if the surrounding ambient temperature is higher than
approximate 40°C. The “ ” icon will appear at the top left of the gauge section if the surrounding ambient temperature is lower
than 0°C. This is not a fault code, but indicates that the unit’s temperature compensation feature is operating.
The charging process will start automatically approximately one minute after the unit is properly connected.
Important: If the unit is overheated, the LCD screen will display the following (the overheat alarm icon, fault icon and the battery
icon will flash; and the clamp icons, arrow icons and the gage without the pointer will light):

display the fault indication icon (the fault icon and the battery icon will flash; and the clamp icons, arrow icons and the gage without
the pointer will light):
Disconnect the charger. Have the battery checked by a qualified technician.
IMPORTANT: If the battery is not fully charged (the battery charge gauge does not reach 100%) after 18 hours of continuous
charging, the battery may have internal damage and will not accept a charge. After 18 hours, the charging process will automatically
