1. Plug the battery charger’s power cord into an AC outlet. The LCD screen will display the following (the clamp
icon will flash, the empty battery icon and the gage without the pointer will light):
2. The charger’s battery clamps are color-coded. Red is positive; black is negative. Connect the battery
clamps correctly to the corresponding connectors on the battery posts following the steps outlined in the
“IMPORTANT SAFETY INSTRUCTION” section at the front of this manual.
Notes:
If the clamps are correctly connected with regard to polarity and the unit is properly connected to
the AC outlet, the unit will be in Standby mode and the LCD screen will display the following (the clamp
icons, arrow icons, the battery icon and the gage without the pointer light solid):
If the clamps are INCORRECTLY connected with regard to polarity, the LCD screen will display the following
(the “+” and “–” inside the battery icon and the fault icon will flash and the clamp icons, the battery icon and
the gage without the pointer will light) and a warning will sound until the clamps are disconnected:
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):
Disconnect the charger and allow the charger to cool for several minutes. Make sure there is adequate
ventilation around the unit before attempting to charge again.
IMPORTANT:
The charger will automatically detect the battery condition. If it detects a problem with the
battery, the LCD screen will display the following (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 cut-off, the LCD screen will display the following (the digital
readout shows “F04”, the clamp icons, arrow icons, battery icon and the gage without the pointer will light
solid):
Disconnect the charger. Have the battery checked by a qualified technician.
4. When the battery is completely charged, the unit automatically goes into float charge mode and the LCD
screen displays the following:
The digital display shows “FLO” to indicate that the unit is in float charge mode. The battery charge gauge
points to 100%, indicating 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.
