Installing Digital Module on the Optical Device

1. Select the adapter (available separately) with the required diameter of insert depending on the outer diameter of the lens of your optical device (see the Table).

2. The designation 42mm / 50mm / 56mm in the title of the adapter refers to the optical diameter of the lens in the optical device.

3. Remove the cap (16) from the 42mm adapter (19) (SKU 79171) by turning it clockwise. To remove the cap from the 50mm (SKU 79172) or 56mm (SKU 79173) adapters, turn it anticlockwise.

4. Degreasing of the body of the optical device before mounting is recommended.

5. Mount the insert (18) onto the adapter (19) as far as it will go.

6. Move the lever (22) to the OPEN position.

7. Mount the adapter with the insert into the lens of the optical device (17).

8. Move the lever (22) from its initial OPEN position to the CLOSE position.

9. Ensure that the adapter fits snugly against the lens.

10. If there is any gap, do the following:

• Loosen the locking screw (20) with an Allen key (S=2mm).

• Tighten the screw (21) with an Allen key (S=4mm) with the force necessary to ensure that the adapter fits tightly against the lens. The clamping forces should be 1 Nm.

• Tighten the locking screw (20).

11. The effort can be tested with a torque screwdriver.

12. Insert the digital module firmly into the adapter so that the pins located in the adapter case fit into the grooves (23) of the digital module. Turn the digital module clockwise as far as it will go. The triangular mark on the digital module and the square on the adapter body must be aligned.

13. To align the digital module, turn the handle (22) to the OPEN position and align the digital module with the horizon.
