5. Safety information
The stroboscopic effect can entice untrained observers to approach or touch
the moving object. Such persons must be warned in sufficient time! The feeling
for the object speed can also be lost during prolonged periods of observation.
Therefore maintain concentration and take breaks from observation if necessary.

Warning!
Certain strobe frequencies may trigger epileptic seizures. Therefore epileptics or
persons susceptible to epilepsy should be warned in due time when a strobos-
cope is going to be used or they should be kept away from the stroboscopic area.

Risk of blinding:
- Do not look directly into the light source!
- Do not aim the light source directly into the eyes of another person!
