1.3 Intended Use
This device only serves to check and adjust the alignment of vehicle headlights.
This device cannot be modified without the express, written consent of the
manufacturer. Any infringement renders the conformity declaration invalid.
1.4 Requirements on Operating and Service Personnel
WARNING
All persons employed in the operation, maintenance, installation, removal and disposal
of the device must
be at least 18 years old,
be mentally and physically suited for these activities,
be demonstrably trained and instructed in writing,
have read and understood the operating instructions, especially the instructions
what to do in the event of defects or malfunctions,
be on record as having been instructed in safety guidelines,
have practical experience in working with vehicle lifts and the hazards inherent in
such equipment.
1.5 Safety Instructions
NOTICE
This device must only ever be operated within its performance limits.
All parts of the electrical system must be protected against damp and humidity.
All service work must be performed by service technicians employed by the manu-
facturer or by authorized service partners.
Never expose the lens to direct sunlight. The bundling of light may cause fire dam-
age inside the housing.
Only ever clean the lens with a soft cloth and a glass cleaning agent.
CAUTION
Optional laser alignment unit: Never look into the laser beam (laser class 2M). Comply
with work safety and accident prevention directives (H&SW regulations) in respect of
laser radiation.

2.4 Electronic Levelling
This headlight tester comes standard with an electronic position sensor which
determines the inclination angle of the device. The software compensates possible
deviations in the X- and Z-axes while calculating the position of the headlights.
The headlight tester may be set up on uneven surfaces even if the ground unevenness
is outside the permissible tolerances, provided that the maximum unevenness does
not exceed the headlight tester’s self-levelling capacity of 3%.
After enabling the respective function, the compensation values can be checked using
a dot or cross hair laser. See section “Operation > Settings > Calibrating the Camera
according to Directive”.
NOTICE
This function must be enabled exclusively by authorised service technicians and is ap-
plicable for the respective test surface only.
