2 Functions and features
The units of design O3D3xx are installed directly behind a pane as protection
against weather conditions� To ensure that the units operate without any
restrictions behind a pane, one of the light seals E3D306 and E3D307 has to
be used� The light seals prevent scattered light and thus impaired measurement
accuracy�
The E3D306 light seal is self-adhesive and is directly applied to the O3D3xx�
The E3D307 light seal is not self-adhesive and is inserted in a corresponding
groove in the pane�
