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 eect 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.

5. Attach the rubber seal (IT/Secure models only): Place

the rubber seal with the groove around the edge of the

black mounting ring of the camera.

Attach the outer shell (IT/Secure models only): Replace

the outer shell and screw all four Allen screws tight using

the supplied Allen wrench. Ensure that the rubber seal

is properly positioned.
