Installing Digital Module on the Optical Device

  • Remove the eyepiece cover (2).
  • Select the Ring Adapter (18) (sold separately) with the insert (17) of the desired diameter depending on the outer diameter of the lens of your optical device (16) (see table). The designation 42 mm / 50 mm / 56 mm in the name of the adapter means the lens diameter of the optical device.

Selection Table for Optical Device Inserts

Ring Adapter modelThe internal diameter of the insert needs to match the outer
diameter of the objective lens housing of the daylight optical
device it is being installed on.
Insert internal diameter, mmSuitable for lens housing of daylight optical devices with an outer diameter of, mm
PSP Ring Adapter 42 mm45.545.5
PSP Ring Adapter 50 mm51.651.6
PSP Ring Adapter 56 mm6059.7-60.6
  • Screw together the Ring Adapter (18) and the digital module along the threads of the mounting area (23) until it stops. Then untighten a little (no more than one turn) so that the lever (22) is on the right side (see Figure).
  • Evenly tighten the screws (19) until the ball joint grips in the Ring Adapter (18).
  • Apply 2-3 strips of double-sided tape to the outer surface of the insert of your choice (14).

  • Push the insert (17) of your choice into the Ring Adapter (18) until it stops.
  • Move the lever (22) to the OPEN position.
  • Before installing the Ring Adapter (18) onto the optical device, it is recommended to degrease the lens body of the optical device (16).
  • Mount the Ring Adapter (18) with the insert (17) onto the lens of the daylight optical device (16) as far as it will go.
  • If the Ring Adaptor (18) with the insert (17) selected according to the table cannot be mounted onto the lens (16), follow the steps below:
    • Loosen the locking screw (20) with a 2mm Allen key.
    • Untighten the screw (21) with a hex wrench (S = 4mm) until the Ring Adaptor with the insert can be mounted onto the lens (16).
  • Move the lever (17) from its initial OPEN position to the CLOSE position.
  • Loosen the locking screw (20) with a 2mm Allen key, if it hasn’t been done before.
  • Tighten the screw (21) using a 4mm Allen key. The clamping force should be 1.5-2 Nm (use a torque screwdriver) to ensure the lever (22) is correctly tightened, while the Ring Adapter with the digital module should not move relative to the body of the optical device (16). If necessary, tighten or loosen the screw (21) to operate the lever (22) in the best way possible.
  • Tighten the locking screw (20) as far as it will go.
  • Turn on the digital module by briefly pressing the ON button (9).
  • Align the image centre on the Forward FN455S display with the image centre of the daylight optical device by carefully tilting the digital module.

  • Turn on the digital module by pressing the ON (9) button. An image will appear on the display after a few seconds.
  • Adjust the eyepiece dioptre ring of your daylight optical device until the symbols in the display are sharp. In future, it will not be necessary to adjust the eyepiece dioptre, regardless of the distance and other conditions.
  • Rotate the lens focus knob (10) to focus on the visual target.
  • Basic settings (brightness and contrast adjustment) can be altered by using the quick access menu.
  • Enter the quick menu with a short press of the M button (7).
  • A short press of the M button (7) enables you to switch between functions, as described below.

Brightness – by pressing the RIGHT (6) and LEFT (8) buttons and changing the display brightness value from 0 to 20.

Contrast – by pressing the RIGHT (6) and LEFT (8) buttons and changing the display contrast value from 0 to 20.

  • Power the digital module off after use with a long press of the ON button (9).

The “Sumlight” Function

  • The SumLight™ function substantially increases the sensitivity of the CMOS array in the event of a reduction in the light level, thus enabling observation in conditions of low light without using the IR illuminator.
  • To activate the SumLight™ function, press briefly the LEFT (8) button.
  • Press the LEFT button (8) once more to switch off.
  • The SumLight™ icon is displayed in the status bar.

Attention! When the SumLight™ function is activated, the noise level in the image increases, the frame rate decreases and the image slows down. Any sharp movement of the device may cause the image to become “blurred”. Such effects are not defects. Luminous white dots (pixels) may be visible on the device’s display. The number of dots may increase when the SumLight™ function is enabled. This is due to the peculiarities of this function and is also not a defect.

Display Calibration

The attachment is configured so that after fitting onto an optical sight that had been properly zeroed, no adjustment of the aiming point is required. Yet if point of impact change is observed after putting on the attachment, you can fix it with display calibration procedure.

  • To enter display calibration mode, first press and hold the M button (7) for 10 seconds.
  • The display coordinates X=0; Y=0 will appear.
  • Use the LEFT (8) and RIGHT (6) buttons to move the display horizontally (X axis) and vertically (Y axis) so that the point of impact moves to the centre of the aiming mark of your optical sight.
  • Press the M button (7) to toggle between the X and Y coordinates.
  • The image offset range is +/- 20 pixels horizontally (X axis), +/- 20 pixels vertically (Y axis).
  • To exit the menu and save the settings, press and hold the M button (7) for two seconds.
