• Once the camera has been aimed, tighten the Allen screws
at both sides of the lens mount (in a clockwise direction)
and the toothed ring
(in a clockwise direction) with the
supplied hook wrench. Do not use excessive force when
doing so as this may damage the camera.
•
Adjustment: Release the lock ring of the lens
and
adjust
the image focus by rotating the lens in its socket. Check the image on the computer
monitor. Make sure that you tighten the lock ring again once you are finished. To
avoid damaging the lens mount, never turn the lens too far or with force.
Caution (only for 160 mm Telephoto lens)
Image Focus
: Due to the lens effect of the dome, the focus of the 160 mm Telephoto
lens shifts slightly once the dome has been mounted. Before mounting the dome,
the Telephoto lens should be rotated by
90°-120° in a counter-clockwise direction
(against the direction in which the lens is screwed). Make sure that you check the
focus of the live image with the dome installed and re-adjust the lens, if required.
• Mount the dome. Use the supplied foil or a lint-free cot-
ton cloth to insert the dome into its seat and turn it in a
clockwise direction. Once again, check the focus of the
camera image on a computer monitor.
If required, gently clean the front of the lens using a soft
cotton cloth before installing the dome. Do not apply exces-
sive pressure to the surface of the glass when cleaning the
lens.

6. Attach the outer shell (IT/Secure models only): Replace
the outer shell and screw all four Allen screws tight using

is properly positioned.
