Pulsar Digex C50 Instruction Manual

• Pulsar Digex C50

The Digex C50 Digital riflescope is designed for round-the-clock use. These riflescopes are designed for hunting, target shooting and recreational shooting, observation, and orientation. The riflescope supports day and night observation modes and color and black and white images. In deep twilight, when the human eye is already unable to discern details of observed objects, the Digex C50 displays a bright image with correct color rendering, prolonging hunting time into the night. In night conditions (absence of starlight, moonlight), it is recommended to use an infrared illuminator with an 850 nm or 940 nm wavelength.

Mounting on the Rifle

Show device diagram

To ensure accurate shooting the Digex С50 riflescope should be properly mounted on the rifle.

1. The riflescope is fixed using the mount, which is purchased separately. Use only high-quality mounts and rings that are designed specifically for your rifle. Follow the mounting manufacturer’s recommendations on the installation procedure and use the proper tool.
2. When mounting the riflescope, adjust the position on the rifle so that proper (comfortable) holding of rifle ensures the distance between the riflescope and eye (eye relief) specified by the Technical Specifications. Failure to comply with this recommendation may result in injury to the shooter by the parts of the riflescope eyepiece when shooting.
3. It is recommended to install the riflescope as low as possible, at the same time it should not be in contact with barrel or receiver.
4. In order to avoid pinching the riflescope body, a tightening torque for the screws of the mounting rings must be not more than 2.5 Nm (22.1 Pound-force inches). A torque wrench is recommended to control the tightening torque.
5. Before using the riflescope when hunting, follow instructions in the Zeroing section.
6. Use of a removable eyecup is recommended (1) to eliminate backlight from the display.
7. It is recommended to use an eyecup while using the riflescope to increase camouflage and avoid detection. Mounting the eyecup on the riflescope eyepiece is carried out using built-in magnets.

How to Zero

Show device diagram

Zeroing at a temperature close to the riflescope’s operating temperature is recommended.

---

Step 1. Take a shot

1. Shooting from a benchrest is recommended.
2. Set a target at a known distance.
3. Adjust the riflescope according to the Powering on and Image Setting section.
4. Select the zeroing profile (see Reticle & Zeroing -> Zeroing Profile main menu item).
5. Point the rifle at the center of the target and shoot.

---

Step 2. Align the reticle with the point of impact

1. Press and hold the controller button (6) to enter the main menu.
2. Add the distance you are aiming at (e.g. 100 meters): Reticle & Zeroing -> Add New Distance . Select the value for each distance digit by rotating the controller ring (6). Press the controller button (6) briefly to switch between digits. After setting the required distance, press and hold the controller button (6) to save it.

3. After adding the distance, it will switch to the Zeroing parameters settings menu . An auxiliary cross will appear in the center of the display, and X and Y coordinates of the auxiliary cross will appear in the upper right corner.

4. Press the controller button (6) briefly to enter the Windage/Elevation submenu.

5. While holding the reticle at the aiming point, move the auxiliary cross until it is aligned with the impact point by rotating the controller ring (6).

6. To change the direction of the auxiliary cross movement from horizontal to vertical, press the controller button (6) briefly.

---

Zoom Zeroing function:

To improve the accuracy of zeroing, you can change the magnification in the menu . The larger the magnification, the smaller the step of shifting the reticle on the display relative to the image from the sensor.

Click value, [email protected] m – when magnifying, x

11.5 – 3.5х 5.75 – 7х 2.875 – 14х

One-shot “Freeze Zeroing” function:

Using the Freeze function allows you to make adjustments without the need to hold the rifle precisely at the initial aiming point – freezing the zeroing screen (refer to Reticle & Zeroing menu item => Distance
submenu => Zeroing Parameters Settings submenu => Freeze submenu or short pressing of the ON/OFF (3) button. The image will “freeze” and the icon will appear.

---

Step 3. Save the coordinates

1. Press and hold the controller button (6) to save a new position for the reticle. The reticle will be aligned with the impact point and it will exit the Windage/Elevation submenu.
