5.1.7 Troubleshooting
If your bike has been exposed to wet conditions for
an extended period, e.g. aer a trip in heavy rain, or
if there have been large dierences in temperature,
the screen of the display may steam up. This mois-
ture does not impair the nction of the display. It is
comparable with the steam on a pair of glasses when
you enter a warmer room having been outside. Aer
a short time in drier and warmer conditions, this con-
densation will vanish leaving no trace.
