should be changed soon.

Always remember to put the cap back on. Make sure that no brake fluid residue re-
mains on the test probe or the tester.
Self-test
Press the button briefly to begin a self-test. All of the Berner
Easy DOT's LEDs will illuminate and then go out. Only a
white and a green LED remain on.
Automatic power-off
The Berner Easy DOT features an automatic shut-off which activates after approximately 1 minute.
LED fluid illumination
The Berner Easy DOT has a special LED that can be used for illuminating the test probe and also
for illuminating the fluid so that dirt particles are visible.
This high-power LED can stay illuminated for up to 80 hours! The LED has a life expectancy of
over 100,000 hours.
