Frequently Asked Questions - ERi 312x50 LEICA

What type of battery does the Leica ERi 312x50 scope use and how to install it?

It uses a CR2032 battery. To install, unscrew the battery compartment cap and insert the battery observing polarity.

How to adjust the diopter on the Leica ERi 312x50 scope?

Turn the eyepiece (1a) until the reticle is optimally sharp. For precise adjustment, aim the scope at a bright background, first turn fully to the right (minus sign) then back to the left (plus sign) until perfect sharpness.

How to change magnification on the Leica ERi 312x50 scope?

Turn the adjustment ring (4): to the right to reduce magnification, to the left to increase it. The lug (4a) helps orientation in the dark.

How to adjust elevation and windage?

Unscrew the protective caps, then turn the turrets: for elevation (5), counterclockwise if impact is high, clockwise if impact is low. For windage (6), counterclockwise if impact is to the right, clockwise if impact is to the left. One click corresponds to 1 cm at 100 m.

How to reset the turret scales?

After adjustment, loosen the fixing screw with a cross-head screwdriver (PH 00) while holding the turret, turn the scale to align zero with the index mark, then retighten the screw.

How to turn on and adjust reticle brightness?

Use the adjustment ring (7) to turn the illumination on/off and set brightness in 9 levels. Automatic shut-off occurs at ±70° of the shooting angle.

How to clean the scope lenses?

First remove coarse particles with a soft brush or by blowing. For stubborn dirt (fingerprints), use a damp cloth then a clean chamois or lint-free cloth. Avoid alcohol and any chemicals.

What to do in case of impact or technical problem?

Protect the scope from impacts not related to shooting. Never attempt to disassemble the scope; repairs are reserved for authorized workshops. Contact Leica customer service.

Where to find spare parts?

Contact Leica customer service ([e-mail]) or your national Leica representative. Available parts include caps, seals and protective caps.

What are storage precautions?

Store the scope in a dry, cool and well-ventilated place, especially in humid climates, to prevent mold.

Dear Customer,

Throughout the world, the name Leica stands for premium quality, accurate precision mechanics, optimum reliability and long service life. We wish you a great deal of enjoyment and every success with your new Leica riflescope.

Your Leica riflescope is equipped with an outstanding optical system and an illuminated dot reticle. This delivers a clear, bright image even in difficult conditions and lighting situations, providing a reliable reticle and a reliable shot every time. It is also easy to operate and functional.

To enable you to make the best possible use of this high performance riflescope features, we recommend that you read these instructions before use.

Inserting the Battery

Mounting

The first requirement for a stable point of impact is proper mounting of the riflescope on the weapon. There are a variety of different fittings available in specialist retailers for this purpose.

We recommending using only high quality components from well-known manufacturers for mounting, which offer the same quality as your Leica riflescope itself.

You can mount the sight yourself, making sure that it is flush and free of tension, but Leica recommends using a specialist workshop.

Dlopter coMpensation

The diopter compensation allows you to adjust your Leica riflescope to your eye. To do this, turn the eye cup (1a) on the eyepiece (1) so that you can see the reticle with optimum sharpness. To achieve the most accurate setting possible, we recommend

pointing the riflescope at a neutral, light background, and
- first turning the rotating eye cup all the way to the right (minus direction, see index point 2), so that you can then turn it back in a positive direction from this position to locate the best sharpness for the reticle.
- This method takes into account the accommodative capacity of the eye, thus ensuring an optimum setting.

elevation anD lateral aDjustMent

In case of variations in the point of impact, adjustment of the reticle to the weapon is required. This is done using the two adjusting towers - (5) for the elevation, (6) for lateral, with both adjusted in the same way:

First unscrew the cap (5.a/6.a) counter clockwise. Once the cap is removed, the knurled dial 5.b/6.b is visible, along with the associated scale 5.c/6.c and the corresponding index point 5.d/6.d. The knurled dials are very precisely graduated, with one click corresponding to 1cm at 100m .

If the point of impact is high, requiring downward correction, turn the knurled dial 5.b counter clockwise, or clockwise to correct upwards if the point of impact is low.

Make the lateral adjustments in the same way: If the point of impact is right, requiring correction to the left, turn the knurled dial 6.b counter clockwise, or clockwise to correct to the right if the point of impact is left.

"zeroling" the tower scales

(same procedure for both towers)

The process is initially the same as that described in the previous section.

Then,

1. unscrew the clamping screw with a Phillips head screwdriver (size PH 00), and

2. hold the knurled dial 5b / 6b in the relevant position while simultaneously turning the scale 5c / 6c so that the zero is aligned with the index point 5d / 6d .

3. Finally, this setting is fixed by tightening the clamping screw.

Once you have done this for both scale dials, you can reliably make the initial setting at the zeroing range after any kind of adjustment by returning to the 0 positions, without the need to remember or make a note of anything.

changing the Magnificatlon

To change the magnification, turn the dial (4) - to the right to reduce the magnification and to the left to increase it. The cam 4.1 improves orientation in darkness: If it is pointing upwards, the middle magnification is set, e.g. on the Leica ER 3 - 12 × 50 this is 6.

IIIuMInateD retIcle aDjustMent

The illumination of the reticle is turned on or off using the setting dial (7):

The same dial can be used to change the brightness of the illuminated dot to 9 levels to avoid any impairment when aiming with different ambient light levels:

MAINTENANCE / CLEANING

Your Leica riflescope does not require any special maintenance. Coarse dirt particles, e.g. sand should be removed with a hairbrush or blown off. Marks such as fingerprints on the front lens and eyepiece lenses can be cleaned with a damp cloth and then wiped off with a soft, clean leather or dust-free cloth (recommend: Leica Anti Fog Solution).

Important:

• Make sure your riflescope is protected from impacts not caused by the weapon.
• Do not exert heavy pressure when wiping highly soiled lens surfaces. Although the coating is highly abrasion resistant, it can be damaged by sand or salt crystals.
• The housing should only be cleaned with a moist leather cloth. Using dry cloths brings a risk of static charge.
• Alcohol and other chemical solutions must not be used to clean the optical system or the housing.

• In addition to the type designation, every Leica rifle scope has its "personal" serial number. Note this number in your documentation for security.

• Do not attempt to dismantle the product. Repairs may only be carried out by authorized workshops.

• Store your riflescope in a well ventilated, dry and cool location, particularly to prevent the formation of fungus in humid climates.

spare parts

If you ever require spare parts for your Leica riflescope, e. e. screw-on covers, seals or caps, contact our Customer Care department (see p. 20 for address) or the Leica agent in your country (see Warranty Card for addresses).
