Handling instructions
For the hub generator light system and battery powered
light systems on pedelecs and Scorpion fs 26 S-Pedelec,
there is an integrated switch at the front light to turn
the lights on and of.
You switch on the tire dynamo by pressing the red but-
ton. To switch off the dynamo move it away from the
wheel.
Hub dynamo
The lighting system with a hub dynamo is
switched on electrically. For this purpose you
will find a switch on the back of the rear light
with three labelled switch positions. With the
switch you can turn the lighting system ON,
OFF or set it to SENSOR. In the SENSOR po-
sition a twilight sensor in the lamp turns the
lighting system on and off automatically de-
pending on the brightness of the environment.
The SON hub dynamo is highly efficient and
works silently. When the dynamo is turned off
it has a very low turning resistance. Although
you can feel the single poles of the used per-
manent magnets very distinctly when turning
it by hand the real rolling resistance is minute.
(The loss is below 1 W at 15 km/h / 9,5 mph.)
