During diving :
When the red indicator, placed at the rear, begins to flash
the light is ending and the internal electronic protective
circuit shuts off automatically the light to prevent any
damage to the batteries. It is recommended to turn the
light off immediately in order to preserve the batteries.
It is possible, after this event, to turn on the light inter-
mittently during a few seconds.
CAUTION :
An electronic control system avoids total discharge;
however, when the red indicator is flashing it is not
recommended to activate too often the light before
a new charge.
