mode, the LED indicator "Battery Dead" lights when the intelligent
battery charger one of the following battery fail conditions ascertains:
a)

c)
d)
The battery charger now stops charging. In a, b and c the battery may
be defective and we advise you to consult your nearest battery service
centre. If the problem is attributable to d, all you have to do is select the
appropriate voltage and proceed to charge the battery.
3. WHEN THE BATTERY IS COMPLETELY
When the LED light "full" lights, the battery is completely charged.
The battery charger now switches to the floating operation mode and
doesn't require your attention until the next time it is used.
When the alternating current plug is removed from the power supply
connection, the battery charger switches off.
The battery charger automatically switches back to the "Stand By"
mode if the direct current cable clamps are removed from the battery
while the alternating current plug is still connected to the power supply.
