7.4. LEVAL calibration and restart

The headlight must be correctly aligned for initial startup (see „7.2. Initial headlight alignment“). 
Everything else works automatically as the LEVAL uses various sensors for support when cycling 
along curves and automatically calibrates itself within a few moments when stationary.
As soon as the calibration is complete, the LEVAL starts to adjust the fixture for optimal alignment.

!

 If the LEVAL is started in motion, calibration may take a little longer.

If it is impossible to reach the optimum LEVAL position, e.g. because LEVAL is blocked, two attempts 
are made to move to the optimum position. The LEVAL then stops the attempts, moves back to the 
centre position and indicates something is wrong by swivelling back and forth briefly and quickly 
three times.
After that, the LEVAL remains in the centre position to protect the technique.

If the centre position is blocked as well, the LEVAL will attempt to move to this position twice anyway. 
Since this is impossible, the LEVAL will position itself as close as possible to the centre position. 
In this case, however, the LEVAL cannot indicate the error by swivelling back and forth briefly and 
quickly.
As soon as the interfering factor has been eliminated, the LEVAL can be restarted using the switch 

3

, i.e. first set to „OFF“ and then back to „ON“.

NOTICE

 If the LEVAL no longer aligns the headlight properly, this may indicate that the power sup-

ply is no longer sufficient. Check the power source and, as a precaution, switch the LEVAL to „OFF“ 
via switch 

3

 so that it is fixed in the centre position.

CAUTION:

 In rare cases, external influences such as electromagnetic interference fields may prevent 

the LEVAL from detecting the correct position and aligning the light field accordingly. Should such a 
disturbance occur, stop cycling immediately to avoid accidents and recalibrate LEVAL via the switch  

3

 by setting the LEVAL briefly to „OFF, then back to „ON“.

!

 Electromagnetic interference fields are rare incidents and mostly confined to small areas.

If malfunctions persist even after several calibration attempts and, if necessary, a change of location, 
please contact your specialist dealer. As a precaution, deactivate the LEVAL by setting the switch 

3

 to „OFF“.

7.5. Adjustment of (headlight) position

If the cut-off line of the headlight 

1

 is too high or too low when cycling along curves (see drawing), 

the LEVAL must be adjusted in its inclination.
The ideal starting position is a 45° angle of inclination to the road.

If the cut-off line is too low when cycling along curves, the illuminated area becomes smaller and 
the LEVAL must be tilted slightly downwards.
If the cut-off line is too high when cycling along curves so that other road users might be dazzled, 
the LEVAL must be slightly raised.
For this purpose, loosen the LEVAL retaining screw 

6.2

, adjust the LEVAL inclination and fasten 

the retaining screw 

6.2

 again to ensure the LEVAL cannot come off or shift all by itself.

Once the LEVAL has been readjusted, also check the setting of the headlight 

1

 and align accor-

dingly, if necessary, as described in “7.2. Initial headlight alignment“.

 WARNING

 Never adjust the LEVAL setting or the headlight range while cycling! This may 

cause severe falls and injuries. 

Do not use the bicycle if the light beam of your headlight is misaligned or attachment compo-
nents are too loose. Blinding oncoming traffic can lead to accidents. To align the bicycle headlight 
or the LEVAL, loosen the headlight retaining screws 

6.1

 and the LEVAL retaining screw 

6.2

. 

Make sure to retighten all screws so that neither the screws nor the headlight or the LEVAL can 
come loose or move all by themselves.

7.6. Additional product/assembly information

!

 All screws required for assembly are 

black

. These can be loosened and screwed on again 

without hesitation.

CAUTION:

 Loosening silver screws renders the warranty null and void (as this would jeopardise 

proper function).
Silver screws are additionally coated with sealing wax. A damaged sealing wax automatically 
leads to the loss of our warranty.
