Installing Thermal Imaging Module on the Optical Device

1. Remove the eyepiece cover (2).

2. Select the Ring Adapter (15) (sold separately) with the insert (14) of the desired diameter depending on the outer diameter of the lens of your optical device (13) (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 (15) and the thermal imaging module along the threads of the mounting area (20) until it stops. Then untighten a little (no more than one turn) so that the lever (19) is on the right side (see Figure).

4. Evenly tighten the screws (16) until the ball joint grips in the Ring Adapter (15).

5. Apply 2-3 strips of double-sided tape to the outer surface of the insert of your choice (14).

6. Push the insert (14) of your choice into the Ring Adapter (15) until it stops.

7. Move the lever (19) to the OPEN position.

8. Before installing the Ring Adapter (15) onto the optical device, it is recommended to degrease the lens body of the optical device (13).

9. Mount the Ring Adapter (15) with the insert (14) onto the lens of the daylight optical device (13) as far as it will go.

10. If the Ring Adaptor (15) with the insert (14) selected according to the table cannot be mounted onto the lens (10), follow the steps below:

• Loosen the locking screw (17) with a 2mm Allen key.
• Untighten the screw (18) with a hex wrench (S = 4mm) until the Ring Adaptor with the insert can be mounted onto the lens (13).

11. Move the lever (19) from its initial OPEN position to the CLOSE position.

12. Loosen the locking screw (17) with a 2mm Allen key, if it hasn’t been done before.

13. Tighten the screw (18) using a 4mm Allen key. The clamping force should be 1.5-2 Nm (use a torque screwdriver) to ensure the lever is correctly tightened (19), while the Ring Adapter with the thermal imaging module should not move relative to the body of the optical device (13). If necessary, tighten or loosen the screw (18) to operate the lever (19) in the best way possible.

14. Tighten the locking screw (17) as far as it will go.

15. Turn on the thermal imaging module by briefly pressing the ON/OFF (9) button.

16. Align the image centre on the Krypton XG50 display with the image centre of the daylight optical device by carefully tilting the thermal imaging module.

17. Align the top and bottom display boundaries of the Krypton XG50 parallel to the horizontal line of the daylight optical device’s reticle.

18. Having reached the best possible position of the thermal imaging module, tighten the two screws (16) until stop. The clamping force should be 6.5-7.5 N·m (use a torque screwdriver to check).
