3.7 Lens Replacement

There is an extra 3.6 mm lens supplied with the unit and one

extra focusing hex key.

To replace the standard 2.5 mm lens with the supplied 3.6 mm

replacement, follow the steps below:

1. Open the front facia using the supplied hex key.

2. Remove the camera sub-assembly from the housing.

– For EX36MNXxxx models, use the supplied hex key to

loosen the set screw that fixes the lens to its holder.

– For EX36C7xxx models, use a Phillips screw driver to

loosen the screw that fixes the lens to its holder.

3. Thread the 2.5mm lens out. Thread the 3.6mm lens in.

4. Power up the whole sub-assembly.

5. Connect video to a monitor.

6. Adjust the back focus. Ensure that the focus is balanced on

both day and night mode. The camera can be forced to

night-mode by covering the photocell.

7. Tighten the lens.

8. Disconnect the power.

9. Mount the whole camera sub-assembly back into the

housing.

10. Adjust the camera sub-assembly mounting position so that

when you mount the sub-assembly to the housing, the lens

will not touch the window.

11. Close the front facia.
