INTRODUCTION

STEINER is one of the largest manufacturers of high-quality optics in the world. STEINER products meet the highest standards in precision and technology. The riflescopes were developed in cooperation with international weapons experts for the particularly strict requirements of military missions all around the globe. They have been tested in harshest operating conditions by special forces in the field and proven highly successful in combats. The riflescopes from STEINER set new standards in terms of performance, quality, and reliability. They are perfectly suitable both for military missions and official operational purposes.

The latest generation of STEINER riflescopes are optionally equipped with Intelligent Firing Solution (IFS). The IFS provides all relevant data in real time at any given time. The integrated ballistics calculator with environmental sensor system (temperature, atmospheric pressure, inclination, wind drift) determines the projectile's point of impact. The display provides information about leveling and the current turret setting in the field of view.

The display can be customized to user needs. Every information can be moved freely or can be deactivated if needed via app for mobile terminals. To do so, the riflescopes with IFS are equipped with a Bluetooth interface.

This user manual contains all the information you need for the use of the Intelligent Firing Solution (IFS).

Any references in the text to figures and item numbers in the images are indicated in parentheses. Example: (3/4) means fig. 3, item 4.

The definitions "on the right" and "on the left" in the text are always related to the direction of fire.

Important instructions concerning safe handling of the riflescope are emphasized by the warning signs IMPORTANT, or NOTE.

IMPORTANT: Observe these notes to avoid any damage to the riflescope.

DESCRIPTION AND CONTROLS

The operating buttons (1/2) for the Intelligent Firing Solution are located on top of the electronics block. The integrated sensor (1/1) measures ambient temperature, atmospheric pressure, roll, and pitch. The incorporated ballistics calculator determines the target distance as function of the sensor values and the adjusted elevation. The battery compartment (1/3) is fitted to the bottom left of the electronics block.

NOTE: The integrated sensor (1/1) must not be covered during use. Otherwise, the IFS will not be able to detect any correct measurement values.

OPERATION

Operating the IFS is done via the following controls:

• On/Off button (2/1)
• Button "to the right" (2/2)
• Button "downwards" (2/3)
• Button "to the left" (2/4)
• Button "upwards" (2/5)

NOTE: A video with an exhaustive description of the Intelligent Firing Solution is available at https://youtu.be/Ff5A_tz96pE.

If the IFS has been switched on, the ON/Off button (2/1) can be used to go to the next menu or to confirm the selection carried out.

By pressing the buttons (2/2, 2/3, 2/4, and 2/5), you can navigate the menus and change previously set values.

NOTE: All values and settings shown in the following menus are only examples.
NOTE: The IFS is not equipped with a rangefinder. The displayed distance is based on the settings of the rifle-scope.

Abb. 3

1. Press and hold On/Off button (2/1) for at least three seconds.
   NOTE: The menu can be individually configured by the user. This is done directly via the operating buttons of the IFS or via the STEINER IFS app.

IFS is switched on. The first menu appears in the riflescope and shows the following information based on the factory settings:

• pitch angle (3/1)
  • distance to the point of impact (3/2)
• current position of the windage adjustment (3/3)
  • recommended position of the windage adjustment (3/4)
  • wind speed and wind direction (3/5)
• current position of the elevation adjustment (3/6)
  • currently selected ammunition (3/7)
• default target size in m and calculated target size in mil (3/8) at the selected distance (3/2)

Instead of the target size (3/8), the time of flight of the cartridge or the impact energy can be displayed.
