The right probe button is used for different functions depending on the current
operating mode the Ecotec E3000 is set to.
The probe handle also offers some LEDs in the flange of the sniffer tip in order to
illuminate the location currently being leak tested.
The LEDs offer some bundled light. The intentional starring suspends the lid closing
reflex and also the eyes do not move anymore which may lead to overheating of the
retina.
When looking into the LEDs „incidentally“ the eye is protected by the lid closing
reflex. Also the permanent movement of the eyes prevents overheating and
consequent damage of the retina.

Warning
Do not stare into the LEDs intentionally for extended times or at a close distance as
this may cause permanent damage to the eye.
