2. Confirm that the rifle is empty, safe, and pointed in a safe direction, with no ammunition near the weapon.
3. Adjust the image and device settings following the steps in the Quick Start Guide on page 8, if you have not done so already.
4. Select the zeroing profile, A, B, or C. See Main Menu > Zeroing Profile on page 33.
5. Based on the distance to the target you wish to zero, select a preset zero distance, OR customize one of the preset zero distances to match. The TH50C V2 supports custom zeroing distances of 1 to 999 meters or 1 to 999 yards. See Reset Zeroing Distance Menu on page 34.
6. Ensure a stable platform and natural shooting position is achieved behind the rifle.
7. Load ammunition, aim, and take one good shot at the target.
8. Make your rifle safe and observe the location of impact on the target.
9. If the point of impact does not match the point of aim (the center of the reticle), adjust the X/Y position of the reticle. See Reset Zeroing Distance Menu > Reticle Zeroing on page 34.

10. In the submenu for the selected zero distance, center the reticle on the aiming point and long press the Photo 📄 and Palette Ⓧ Buttons at the same time to freeze the image. The image freeze ✦ icon appears at the bottom of the screen.

11. Select the axis (X or Y) along which to move the reticle by short pressing the Control Turret to toggle between X and Y.

12. Adjust the X/Y position of the reticle until the reticle matches the point of impact.

a. Rotate the Control Turret counterclockwise to move in the positive direction: X= Right and Y= Up.

b. Rotate the Control Turret clockwise to move in the negative direction: X= Left and Y= Down.

c. Upon moving the reticle, a white dot appears onscreen, representing the original position of the reticle.

1. Long press the Control Turret to save the reticle position.

2. Take a confirmation shot—the point of impact should now match the point of aim. If not, adjust the X/Y position of the reticle again.

For detailed Zeroing instructions, please see Reset Zeroing Distance Menu > Reticle Zeroing on page 34.

17. NON-UNIFORMITY CORRECTION

A non-uniformity correction (NUC) allows a thermal imager's sensors to correct its pixels and eliminate any image defects caused by pixel drift. A NUC will be performed automatically each time the BOLT TH50C V2 is powered on.

The TH50C V2 has three NUC modes, automatic (A), manual (M), and background (B). The selected NUC mode (A, M, or B) appears in the top status bar. For instructions on setting the NUC mode in the main menu, see Main Menu > Calibration on page 37.

Automatic Mode

In automatic mode (A), the TH50C V2 will perform a NUC automatically according to the internal software algorithm. There is no need to close the objective lens cap (15) as the TH50C V2's internal shutter covers the sensor.

A countdown timer will appear in the top status bar instead of the calibration mode when 5 seconds remain until an automatic NUC is performed. Short press the Power ⏻ Button before the countdown concludes to cancel the automatic NUC. The timer will appear only after the microbolometer temperature has stabilized—after approximately 10 minutes of continuous operation of the TH50C V2.

NOTE: A manual NUC (see below) may be performed at any time while in Automatic (A) mode.

Manual Mode

In manual mode (M), the user independently determines the need to perform a NUC based on the quality of the observed image. It is not necessary to close the objective lens cap (15) during a manual NUC, as the internal shutter covers the sensor.

To perform a manual NUC while in manual mode (or automatic mode):

1. From the home screen, short press the Power ⏻ Button.

2. A manual NUC is performed instantly.

Background Mode

In background mode (B), the user independently determines the need to perform a background NUC based on the quality of the observed image. A background NUC uses less power than an automatic or manual NUC because it does not use the imager shutter to cover the sensor; instead, the user must close the lens cap (15).

To perform a background NUC while in background mode:

1. Close the objective lens cap (15).

2. From the home screen, short press the Power ⏻ Button.

3. A prompt to close the lens cap appears onscreen. The background NUC starts after about 4 seconds.

NOTE: If the lens is not properly covered, a temporary “image burn” will remain in the image until the next non-uniformity correction. This “image burn” is temporary and is not a defect or sign of permanent damage.

18. PHOTOGRAPHY AND VIDEO RECORDING

The TH50C V2 is equipped with video recording and image capture. All videos and photos are automatically saved on the internal 32 GB memory storage.

27. BASIC INSPECTION

It is recommended to carry out a technical inspection before each use. Please check the following:

• The rifle scope appearance: there should be no cracks in the body or visible damage.
• The condition of the objective lens and eyepiece: there should be no cracks, greasy spots, dirt, or other deposits on the lens.
• The internal rechargeable battery pack should be fully charged.
• The control buttons and turret should be in working order.
• The mount should be tight and correctly installed on the rail.

28. BASIC MAINTENANCE

Always replace the objective lens cap (15) after use to avoid damaging or scratching the lens. Never touch the lens directly; oil from your skin can damage the lens coating and surface.

Basic maintenance should be carried out at least twice a year and includes the following steps:

• Wipe the surface of the external metal and plastic components with a clean, dry cotton cloth. Do not use chemical, corrosive, or abrasive cleaners. Canned air may also be used to clean the external components.
• Clean the electric contacts and battery slots on the rifle scope using a non-greasy organic solvent.
• Check the lens and eyepiece. If necessary, remove any dirt or sand from the optics; a non-contact cleaning method is preferred.

- Cleaning the exterior of the lens should only be done with the included microfiber lens cloth or a similar product. Only clean the lens when it is visibly soiled. Frequent wiping or cleaning can degrade the anti-reflective lens coating.

Turn on Ultra-clear mode. See Main Menu > Ultra-clear on page 31.

In warm-temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high temperature contrast. Accordingly, the image quality produced by the rifle scope will be higher. In low-temperature conditions, the background will cool down to roughly the same temperature, and thus the temperature contrast is substantially reduced and image detail can go down as there is less contrast in the scene. This is a normal function of a thermal imager and is no indicator of actual detector performance.
