Outdoor sports enthusiasts can get the precise measurements they need to connect with their target with the Alpen 7×24 OLED Rangefinder. This compact device, which has an easy-to-grip dual-barrel design, quickly and accurately measures distances up to 2000 yards for hard targets and 700 yards for soft targets. The measurements, which can be given in yards or meters, are shown on an OLED display with a red readout and adjustable brightness.

SET UP

Installing Battery
Remove the battery cap by turning the cap in a counter-clockwise direction. Insert (1) CR2 lithium battery (-) terminal side first. The (+) terminal should be facing out, Fig.1. Place the cap onto the (+) battery terminal and reinstall the battery cap by turning the cap in the clockwise direction.
CAUTION – Be careful to not cross-thread the cap or overtighten.

Diopter Adjustment
The diopter adjustment is used to bring the OLED display into sharp focus along with the target image. The diopter adjustment can turn clockwise (+) or counter-clockwise (-) from the eyecup and adjusted depending upon the user’s prescription, Fig.2.

OLED DISPLAY INFORMATION

• A. Degrees Display
• B. Circle Center Reticle
• C. Range Display
• D. Meters and Yards Unit
• E. Battery Status
• F. Brightness Display 0-6
• G. Horizontal Component Distance Mode (HCD)
• H. Line of Sight Mode (LOS)

When the MEASURE button is pressed, the OLED display will power on and show the circle center reticle, unit of measure (Y or M), LOS angle degree or HCD measurement, and battery status. The display will remain active for up to 10 seconds. The first press will power on and display the scan mode and unit of measure. Second press will start scanning. If you press and hold the MEASURE button, you will noticed a blinking “S” and it will continuously scan objects until the button is released.

SETTINGS

To change display settings, press the MEASURE button to power on and press and hold the MODE button for 3 seconds until you see the screen below, Fig.3. Depress the MODE button and the first setting menu will be brightness, then unit of measure, then mode conversions.

Use the MODE button to change the setting menu and the MEASURE button to select the options.

Once you have the desired settings, press and hold the MODE button for 3 seconds until you see the power on screen again. At this point the rangefinder is ready for scanning objects.

LOS AND HCD MODES

• Line of Sight Mode (LOS): In the LOS Mode, the following information is displayed: Horizontal distance to the object and the angle that the device is being held in relation to the target.
• Angle Measurement: The angle of measurement between your position and any target can be displayed in the upper area of the display.
• Horizontal Component Distance Mode (HCD): The HCD mode shows you the horizontal and straight distance to the target.

Example: A LOS range of 500 yards at a 30° decline equals to a HCD of 433 yards.

CLEANING & STORAGE

Blow away any dust or debris on the lens (or use a soft lens brush). To remove fingerprints or other smears, clean with a soft cotton cloth rubbing in a circular motion. A “microfiber” cleaning cloth (available from camera or computer retailers) is ideal for the routine cleaning of your optics. For a more thorough cleaning, photographic lens tissue and photographic-type lens cleaning fluid or isopropyl alcohol may be used. Always apply the fluid to the cleaning cloth – never directly on the lens. For extended periods of storage, store in a cool and dry environment to avoid any damage to the device.
