DISPOSAL OF ELECTRICAL AND
ELECTRONIC EQUIPMENT

(Applies within the EC, and for other European countries with segregated waste collection systems)
This device contains electrical and/or electronic components and should therefore not be disposed of in general
household waste!
Instead it should be disposed of at a recycling collection point provided by the local authority. This costs you
nothing.
If the device itself contains removable batteries or rechargeable batteries, these should first be removed and,
if necessary, properly disposed of (refer to the specifications in the manual for your device).
Further information on this point is available at your local
administration, your local waste collection company, or
in the store where you purchased this device.

INSERTING AND CHANGING
THE BATTERY

Leica telescopic sights with illuminated reticle are fitted with a 3 Volt lithium button cell, type CR 2032 to
save energy.

Note:
The life of a battery depends not just on the usage profile but on many other factors and can therefore differ
widely.

Leica Magnus

1. Open the cover (3) on the battery compartment (3d)
by turning it anticlockwise (A).
2. Insert the battery with the positive contact pointing
upwards (B).
3. Close the cover again. To do this, turn it clockwise until
you feel resistance from the rubber sealing ring (3e).

Important:
Do not exert force when closing the
cover.

BATTERY CAPACITY DISPLAY

The illuminated dot from
the reticle is used for the
display. The display appears for the first 10 s after turning on:

Leica Magnus

Note:
• After the illuminated reticle is automatically turned off
and back on (see p. 30), the display is not repeated.
• With the factory default settings, i.e. when the
telescopic sight is delivered, this display is turned on.
However, you can turn it off (see below).

Turning the capacity display on and off

1. Set the rotary rocker switch (3) to day mode (“sun”
setting) (a).
2. Use the rotary rocker switch to set the minimum
brightness (see p. 29) and then release it (b).
3. Hold down the left of the rotary rocker switch for at
least 20s (c).
• The illuminated dot flashes to confirm your setting
(for the first 10s after adjustment):

Leica Magnus

Note:
Your setting is retained both after manually turning the
illuminated reticle off and on, and after changing the
battery.

MOUNTING

The first requirement for perfect targeting is proper
mounting of the telescopic sight on the weapon. There
are a variety of different fittings available in specialist retailers for this purpose.
We recommend consulting a specialist workshop for advice on mounting, making sure that they achieve a flush
and stress-free construction. The workshop should only
use high quality components from well-known manufacturers for mounting, which offer the same quality as your
Leica Magnus telescopic sight.

DIOPTER COMPENSATION

The diopter compensation allows you to adjust your Leica
Magnus telescopic sight to your eye. To do this, turn the
eye cup (1a) on the eyepiece (1) so that you can see the
reticle with the maximum sharpness. To achieve the most
accurate setting possible, we recommend
– pointing the telescopic sight at a neutral, light background, and
– first turning the eye cup all the way to the left, so that
you can then turn it back from this position to the right
until you find the best sharpness for the reticle. This
method takes into account the accommodative capacity
of the eye, thus ensuring an optimum setting.

CHANGING THE MAGNIFICATION

To change the magnification, turn the dial (8) – to the
right to reduce the magnification and to the left to increase it. The cam (8a) improves orientation in darkness:
If it is pointing upwards, approximately the middle magnification is set.

PARALLAX COMPENSATION

Leica Magnus telescopic sights up to a maximum magnification of 12x are calibrated to a range of 100 m without parallax, which means that you can simultaneously
see the reticle and a target with perfect sharpness at
this range.
Any variations in the point of impact due to the eye being not precisely centered are usually negligible.
At higher magnifications, however, these variations need
to be taken into account. Therefore, telescopic sights
with magnification ranges above 12x feature parallax
compensation.
To use this feature, on the corresponding dial (9) for
the tower on the left of the barrel until you can see the
target with absolute sharpness. To ensure that the setting is as accurate as possible, we recommend always
using the strongest magnification. An optimum setting
is achieved when the reticle and image do not move
against each other when you change the position of the
eye relative to the eyepiece. 

ELEVATION AND LATERAL ADJUSTMENT

1. Mount the telescopic sight on the weapon
(see p. 24).
2. Point the reticle and the weapon’s running axis
with the two adjusting towers at the selected zeroing range
(e.g. 100 m). This can be done using a laser cartridge,
for example.
3. Fire a test shot to establish the point of impact. It is
beneficial to fix the weapon in position on a shooting
rest or sandbags.
4. Without changing the position of the weapon, adjust
the reticle using the two adjusting towers (4/5) precisely to the target.

Leica Magnus

This is done using the two adjusting towers – (4) for the
elevation, (5) for lateral, and in the same way in both
cases:
5. First unscrew the cover (4c/5c) anticlockwise. When
the cover is removed, the knurled dial (4d/5d) is visible, along with the associated scale ring (4e/5e) and
the corresponding index point (4a/5a).
6. Then make the settings with the knurled dial.
The dial has very fine graduations, and a click corresponds to a variation in the point of impact of around
10 mm/ 1/3 MOA at 100 m (not taking account of ballistic conditions).

If the point of impact is high (high shot), turn the knurled
dial (4d) anticlockwise,

Leica Magnus

Make the lateral adjustments in the same way:
If the point of impact is right (right shot), turn the
knurled dial (5d) anticlockwise,

Leica Magnus

“ZEROING” THE TOWER SCALES

(same procedure for both towers)
The process is initially the same as that described in the
previous section (points 1 and 2).
Then,
1. While holding the knurled dial (4d/5d), unscrew the
adjusting screw (4b/5b) with a coin (A), and
2. Turn the scale dial (4e/5e) until the zero is lined up
with the index point (4a/5a) (B).
3. Finally, the setting is fixed by tightening the adjusting
screw while holding the knurled dial (4d/5d)..
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.

USING THE ILLUMINATED RETICLE

The illuminated element of Leica Magnus telescopic sights
consists of a central illuminated dot for all reticle types.
Note:
Details of the different reticle types can be found at:
http://de.leica-camera.com/sport_optics/rifle_scopes_
magnus/Absehen/

Leica Magnus

You can use the rotary rocker switch (3) to choose between three modes, indicated by corresponding markings:
Central switch position = Off
“Moon” setting = Night mode
“Sun” setting = Day mode

Leica Magnus

Day and night mode differ in terms of the brightness adjusting ranges for the illuminated dot. In both modes,
you can adjust the brightness in 60 increments to the
conditions or use or your own preferences.
This is also done using the rotary rocker switch: Pressing
to the left reduces the brightness, pressing to the right
increases it. Press once for a single increment or hold
down to increment continuously.

Note:
Your settings are retained even after turning off and on
again.

AUTOMATIC SHUTDOWN

Regardless of the selected mode, the illuminated reticle
is deactivated automatically to conserve the battery in
various situations, which correspond to not being used
when hunting:
– If the telescopic sight is not moved for longer than 3
minutes (for example in a hide)
– If the telescopic sight is tilted to the side by more than
45° (for example when the weapon is laid down temporarily)
– If the telescopic sight is tilted more than around 80°
upwards or around 65° downwards or is vertical (for
example when shouldering the weapon). As soon as
these conditions no longer apply, the illuminated dot is
reactivated with the brightness set previously.

MAINTENANCE / CLEANING

Your Leica Magnus telescopic sight does not require any
special maintenance. Coarse dirt particles, such as sand,
should be removed with a fine hair brush or blown away.
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. 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.

Important:

• Make sure you protect your telescopic sight from impacts.
• Store your telescopic sight in a well ventilated, dry and
cool location, particularly to prevent the formation of
fungus in humid climates.
• Leica telescopic sights are water tight to a depth of
4m (0.4 bar). This is the case if the seals are perfect,
which is guaranteed if the covers on the elevation and
lateral adjustment and the battery compartment cover
(3/4c/5c) are screwed tightly against the respective seals (3e/4f/5f). Make sure that these seals are
undamaged. If they are damaged, they should be replaced immediately.
• Do not attempt to dismantle the product. Repairs
should be carried out exclusively by Leica Customer
Care centers.
• In addition to the type designation, every Leica telescopic sight has its “personal” serial number. Note
this number in your documentation for security.

SPARE PARTS

If you should require any spare parts for your Leica telescopic sight, e.g. screw-on cap, seals or covers, please
contact our Customer Care department (see p. 35 for
address) or the Leica office in your country (see warranty card for addresses).
