SAFETY REMARKS

WARNING
Non-compliance with the following points may result in serious injury or death.

LASER

• The use of any operations not described in this manual or any alterations on the device may result in hazardous radiation exposure.
• The laser device is active and emitting an invisible laser beam as long as the display in the eyepiece is active. Never point the laser focusing optics at a person or animal.
• Do not depress any of the two buttons while aiming at a human eye or while looking into the optics from the lens side.
• Never aim the laser at an eye.
• Do not aim the laser at people or animals.

GENERAL INFORMATION

• Avoid looking directly at bright light sources with your Leica Rangemaster to prevent eye injury.

CAUTION
Non-compliance with the following points may result in personal injury or damage to the device.

LASER

• Avoid touching any of the two buttons while the distance measurement function is not in use to prevent an accidental activation of the laser beam.
• Do not attempt to disassemble, reassemble or repair the Leica Rangemaster yourself. Emitting laser radiation may pose a serious health risk. The manufacturer warranty is void, once a device was disassembled, reassembled or repaired.
• Remove the battery immediately and stop using the device if the device housing is damaged or if it emits a strange sound after being dropped or behaves unexpectedly for any other reason.

GENERAL INFORMATION

• Keep the device out of the reach of small children.
• Do not use the device while walking! You might trip and fall.
• Do not combine the operation of your Leica Rangemaster with other optical components, e.g. lenses or binoculars. Using the Leica Rangemaster in conjunction with another optical device increases the danger of damaging your eyes.
• Do not attempt to disassemble or modify the device; exposing the internal electronics may cause damage, injury or electric shock.

BATTERY

• Only the battery type stated in this manual must be used. Any improper use of the batteries or the use of unapproved battery types may result in an explosion!
• Do not expose the battery to sunlight, heat, humidity or moisture for prolonged periods of time. It must not be placed in a microwave oven or a high-pressure container as this would pose a fire or explosion hazard!
• Never dispose of batteries in fire and never attempt to heat, recharge, dismantle or break open a battery.
• Batteries must always be stored out of the reach of children. Do not leave batteries lying around, as they could be swallowed by children or pets.

CARRY STRAP

• Carry straps are usually made of very robust material. You should therefore keep it out of the reach of children. A carry strap is not a toy and poses a strangulation risk.
• Use the carry strap only for its intended purpose on a camera or on binoculars. Any other use poses the risk of injury and may possibly result in damage to the carry strap and is therefore not permitted.
• Carry straps should also not be used for cameras/binoculars during sports activities that pose a risk of entanglement (e.g. when mountain climbing and similar outdoor activities).

IMPORTANT INFORMATION

GENERAL INFORMATION

• Do not attempt to take the device apart yourself. Repairs must only be carried out in authorized workshops.
• Remove the battery from the housing if you will not be using the product for an extended period of time.
• Low temperatures impair battery performance. Carry the rangefinder close to the body in low ambient temperatures and insert a fresh battery.
• Make sure to store the batteries in a cool, dry place.
• Depleted batteries must never be disposed of in household waste as they contain toxic materials that are harmful to the environment. Battery collection points are provided at most large retail outlets; alternatively, you can dispose of old batteries at a local special waste collection point to ensure correct recycling.
• Do not touch the glass surfaces with your fingers, especially if you have previously applied hand cream, insect repellent, etc. These substances may contain chemicals that damage or destroy the coatings on the glass surfaces.
• Make a note of the serial number of your device, as this information will be extremely important in case of loss.

MEASURING VALUES

• The influence of all ballistically relevant influencing factors is greatly increased at longer ranges and considerable variations may occur. The ballistic values displayed should therefore only be viewed as a guideline.
• Regardless of whether this information is used, you are responsible for assessing the relevant hunting situation.
• Powerful electric fields, e.g. emanating from radar systems, may cause errors and/or faulty values.
• The geomagnetic field can similarly cause value deviations.

  • Object is not sufficiently reflective
• Note: The reticule remains lit for another 6 s after you release the main switch. The Leica Rangemaster shuts down automatically when the display disappears.

SCAN MODE
(OBJECT TRACKING)

• Press the main switch briefly
• Aim at the object while target mark is lit
• Press and hold main switch for approx. 2.5 seconds
• The device switches to scan mode and will then measure continuously. Scan mode is indicated by a change in the display. A new measured value appears after approx. 0.5 seconds.

Notes

• In scan mode, the EHr compensation value is shown only after the final measurement.
• Power consumption is much higher in scan mode than for single measurements.

METERING RANGE/ACCURACY
Maximum range is achieved in the following scenarios.

• Highly reflective target objects
• At a visual range of around 10 km
  Long ranges can be reliably measured or achieved by holding the rangefinder very steady and/or placing it on a solid surface.

The measuring range is influenced by the following factors:

tree)

The following range/accuracy applies in sunlight and with good visibility:

Range

(in meters)

| Accuracy (1 σ ) Normal Operation| Accuracy (1 σ ) Scan mode
---|---|---
10–200| ± 0.5 m| ± 1.5 m
200–400| ± 1 m| ± 2 m
400–800| ± 2 m| ± 3 m
Above 800| 0.5%| 0.5%

Note: Distances below 200 m are displayed with an accuracy of one decimal place, e.g. 164.5.

VIEWING SETTINGS
You can display values at any time to check your settings.

• Press the menu selection button 2x briefly
• The selected measurement system (EU or US) and EHr (only if the function is activated) will appear below the reticule (e.g. instead of the distance) alternating for 2 s each.

BALLISTICS

EQUIVALENT HORIZONTAL RANGE (EHr)
Shots at higher or lower elevation targets are subject to changed ballistic conditions. They require knowledge of the equivalent horizontal range, which is relevant for hunting. Knowledge of the equivalent horizontal range is important, for example when using ballistic reticles. EHr values are indicated by the additional EHr display.

• Press and hold the menu selection button

• Press the menu selection button 1x briefly

• EHr appears.

• Press the main switch several times briefly until the desired setting appears (ON, OFF)

• Press the menu selection button briefly
  Notes

• Horizontal EHr measurements can also result in values that differ from the “straight line” measured distance, e.g. if the temperature and/or the atmospheric pressure vary from pre-programmed values.

• EHr values are provided only between 10 m and 1100 m for safety reasons. Beyond that, only the actually measured, linear range is provided.

CARE/CLEANING

• Your Leica rangefinder requires no special care.
• Coarse dirt particles like sand should be removed with a soft brush or simply blown off.
• Do not use excessive force when cleaning a severely soiled lens surface. The coating is abrasion resistant, but not impervious to sand or salt crystals.
• Always rinse off any traces of salt water! Dried salt crystals could damage the surfaces.
• Fingerprints, etc. on front lenses and eyepiece lenses can be pre-cleaned with a damp cloth and then wiped dry with a clean leather or lint-free cloth.
• The rangefinder should be stored in a well-ventilated, dry and cool place to prevent fungal growth (particularly important in humid climates).
• Do not use alcohol or chemical cleaning solutions on the optics or housing.
