... the lamp pairs are not
dimmed synchronously?
Only applicable to light LC*/D
Note: Owing to production-related
dispersions in the ballast units,
the two lamps pairs may become
asynchronous under unfavour-
able conditions (one ballast unit
increases while the other one al-
ready decreases in light intensity).
To resynchronize the two ballast
units, the touch switch [27 .1] must
be pressed for 10 seconds.

flicker?

use them for a certain time (about
100 h) in undimmed condition
(see information provided by the
ma nufacturer).
