* All 5 LEDs ash quickly: The battery is empty and is be-
ing switched o, or is overloaded.
› If the battery is overloaded, it will switch back
on aer a short idle period and can then be used
normally.
› If the battery is empty, it will work once again
briey following a short period of rejuvenation and
will then switch back o. It must now be charged.
** The 1st LED ashes quickly: A charging fault is present.
› If this occurs, put the battery in the docking station
for a short period of time or insert the plug of the
charger into the battery. The charger performs a re-
adjustment. If the LED still ashes, take the battery
to your specialist cycle shop and have it checked.
