This means that you do not have to worry about them getting wet - they are absolutely waterproof to a depth of 5 m and there is no fogging in the internal optical system thanks to a nitrogen filling. Attaching the carrying strap and the eyepiece cover If you want to attach the eyepiece cover to the carrying strap, you must thread the strap through the eyelet on the eyepiece cover before you attach the carrying strap to the left-hand side of the bino- culars. Attaching the lens covers To fit the two lens covers, place the rubber rings of the covers over the binocular tubes from the lens side so that the covers open downwards.18 Inserting and changing the battery The Leica Geovid BRF binoculars are supplied with power by one 3 Volt lithium cell (e.g. Duracell DL CR 2, Ucar CR 2, Varta CR 2, or other- CR 2 types). p. 27

1. Open the battery compartment (9) cover (10) by

turning it anticlockwise, with a coin for example.

2. Insert the battery with its positive contact

facing forwards (as marked in the battery compartment).

3. Close the cover again by turning it clockwise.

• Batteries should be stored in a cool dry place.

• If the binoculars are not going to be used for a long time, the battery should be removed.

• Batteries should never be put in a fire, heated, recharged, disassembled, or broken apart.

• Used batteries may not be disposed of as normal, household waste as they contain hazar- dous materials that are harmful to the environ- ment. To ensure that they are properly recycled, they should be returned to the dealer or dispo- sed of as special waste (at a collection point).19 english Battery charge level A new battery is sufficient for more than 500 measurements at 20°C. Depending on the conditions of use, the battery life can be significantly shorter or longer than this. Low temperatures and frequent use of the scan mode (see p. 23) shorten the battery life. A flat battery is indicated by a flashing measured value and target display. Once this flashing starts, around 50 more measurements are possible, but with a continuously reduced range.

Warning: Cold conditions impair the battery

performance. At low temperatures, the Leica Geo- vid BRF should therefore be carried close to the body and used with a fresh battery.20 Adjusting the eyepiece cups / Using with and without glasses The eyepiece cups (1) can easily be adjusted by turning them and lock securely into the selected position. They can also be completely removed for thorough cleaning. For viewing with glasses (Figure A), they remain in their fully screwed in position. For viewing without glasses, they are unscrewed by turning them anticlockwise. Two positions are available for optimum adjustment (Figures B, C). If the eyepieces are very dirty, it is recommended that the eyepiece cups are removed for clea- ning (Figure D). To do this, they are removed by pulling them slightly when in their fully unscrewed position. Adjusting the eyebase The individual eyebase is adjusted by bending the binoculars around the hinged axis (8). The right and left fields of view must merge into a circular field. A B C D21 english Setting the focus / Dioptre compensation On the Leica Geovid BRF binoculars, the focus is set for objects different distances using the central focusing dial (2). The two dioptre compensation dials (3/7) are used to compensate for individual vision defects for viewing without glasses and for focusing on the target mark. Run carefully through the steps described below. You will then be able to fully utilize the optical capabilities of the binoculars.

1. Turn both dioptre compensation dials to their

2. While viewing with both eyes, focus on a distant

object using the central focusing dial.

4. Once the target appears, while continuing to

view with both eyes adjust the right-hand diop- tre compensation dial (7, red index) so that the target is in focus in the right-hand optical field.

5. Then, with the target still activated but now

viewing with the right eye only, use the central focusing dial for fine focusing of the image in the right-hand tube.

6. Then adjust the image in the left-hand tube to opti-

Note: When looking through the binoculars with the right or left eye only, the other eye should be kept tightly shut, or simply place your hand in front of the lens on the other side of the binoculars. Distance metering To measure the distance to an object, you must lock onto it precisely. To do this, activate the tar- get mark by pressing the release button (5) once. Once the button is released, the target mark remains illuminated for around another 4 s. If the button is held down, the target marker is illuminat- ed continuously. While it is illuminated, lock onto the object and carry out the distance metering by pressing the release button again. The measured value is then displayed. The target mark disap- pears briefly during metering. You can start a new measurement at any time by pressing the release button again, as long as the target mark is illuminated. If the object distance is less than 10 meters / yards or if the range is exceeded or the object does not reflect sufficient light, the display shows

When the display goes out, the distance meter is automatically deactivated. Notes:

• Depending on the angle of the optical systems to each other, i.e. the set interpupillary distance, the displays may appear slightly slanted.

• The Leica Geovid BRF binoculars are available in different versions displaying the distance in meters or yards. Externally, the different ver- sions can be recognised by the information on the cover of the central focusing dial.23 english Scan mode The Leica Geovid BRF binoculars can also be used for continuous metering. If you hold down the release button (5) after the second press, after approx. 0.5 s the binoculars switch to this scan mode and then perform constant metering. This can be identified by the changing display: A new measured value is output approx. every 1.5 s. Scan mode is particularly practical when metering small targets. Notes:

• Scan mode consumes more power than individ ual metering due to the constant metering.

• Scan mode automatically shuts down after 10 s, to preserve the battery in case the button is pressed accidentally. Metering range and accuracy The Leica Geovid BRF binoculars have a metering accuracy of up to ±1 meter / yard. The maximum range is achieved with highly reflec- tive target objects and visibility of 10 km. The metering range is influenced by the following factors: Range Higher Lower Colour of object White Black Angle to object Vertical Acute Object size Large Small General brightness Low High (cloudy) (midday sun) Atmospheric Clear Hazy conditions Homogeneous Inhomogeneous Object structure (building wall) (bush, tree) With sunshine and good visibility, the ranges and accuracies are as follows: Range 10m/yds up to approx. 1200 m/1300 yds Accuracy ±1 m/yd up to 350 m/380 yds ±2 m/yds up to 700 m/763 yds ±0.5 % above 700 m/763 yds24 Maintenance / Cleaning Your Leica Geovid BRF binoculars do not require any special maintenance. Coarse dirt particles, such as sand, should be removed with a fine hair brush or blown away. Fingerprints etc. on lenses or eyepieces can be wiped off with a soft, clean leather or dust-free cloth. For heavy soiling, e.g. to the rotating eyepiece cups, the binoculars can be cleaned by simply rinsing them under running water. Saltwater can be rinsed off in the same way.

Warning: Do not exert excessive pressure when

wiping heavily soiled lens surfaces. Although the coating is highly resistant to abrasion, sand or salt crystals can still damage it. As well as its type designation, each set of Leica Geovid BRF binoculars have their „personal“ serial number. Make a note of this number in your docu- ments for security. Accessories Order no.
