Adjust the trimmer slowly, in the preset brightness
conditions, until the warning light next to the
trimmer turns on. Once you pass the threshold (LED
on), turn slightly back in the opposite direction.
After making the adjustments make sure
that the plug is closed tight to ensure
perfect sealing.
7.1.5.2 Disabling the photocell
To disable the illuminator (photocell) activation,
fully rotate the photocell adjusting trimmer
counterclockwise (Fig. 9, page 9). This way the
illuminator is activated. To deactivate the illuminator,
act on the external command.
7.1.6 Adjusting the power of the
infrared illuminators
The illuminator is set in the factory to
provide maximum power. If long distances
should not be reached or if the image is
over-exposed for excessive brightness,
decrease the power, so that energy saving is
also obtained.
