Mounting

1. Remove the protective cover from the eyepiece of the front lens mounted module.

2. Select the Ring Adapter (1) with the insert (4) of the desired diameter depending on the outer diameter of the lens of your optical device (5) (see Table). The designation 42 mm / 50 mm / 56 mm in the name of the adapter means the lens diameter of the optical device.

3. Screw together the Ring Adapter (1) and the front lens mounted module along the threads of the mounting area (2) until it stops. Then untighten a little (no more than one turn) so that the lever (6) is on the right side (see Figure).

4. Evenly tighten the screws (3) until the ball joint grips in the Ring Adapter (1).

5. Apply 2-3 strips of double-sided tape to the outer surface of the insert of your choice (4).

6. Push the insert (4) of your choice into the Ring Adapter (1) until it stops.

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

8. Before installing the Ring Adapter (1) onto the optical device, it is recommended to degrease the lens body of the optical device (5).

9. Mount the Ring Adapter with the insert onto the lens of the daylight optical device (5) as far as it will go.

10. If the Ring Adapter (1) with the insert (4) selected according to the table cannot be mounted onto the lens (5), follow the steps below:

• Loosen the locking screw (7) with a 2mm Allen key.
• Untighten the screw (8) with a hex wrench (S = 4mm) until the Ring Adaptor with the insert can be mounted onto the lens (5).

11. Move the lever (6) from its initial OPEN position to the CLOSE position.

12. Loosen the locking screw (7) with a 2mm Allen key, if it hasn’t been done before.

13. Tighten the screw (8) with an Allen key (S = 4mm). The clamping force should be 1.5-2 Nm (use a torque screwdriver) to ensure the lever is correctly tightened (6), while the Ring Adapter with the front lens mounted module should not move relative to the body of the optical device (5). If necessary, tighten or loosen the screw (8) to operate the lever (6) in the best way possible.

14. Tighten the locking screw (7) as far as it will go.

15. Turn on the front lens mounted module.

16. Align the image center on the display with the image center of the optical scope by carefully tilting the front lens mounted module.

17. Align top and bottom display boundaries parallel to the horizontal axis by turning the front lens mounted module clockwise or counterclockwise.

18. Having reached the best possible position of the front lens mounted module, tighten the two screws (3). The clamping force should be 6.5-7.5 N·m (use a torque screwdriver to check).
