• Target priority switching system, which can be chosen according to the target, is employed
• Sustained pressing of the POWER ON/Measurement button enables continuous measurement function
• Automatic power shut-off (after approx. 8 sec. unoperated)

The Nikon Laser Rangefinder uses an invisible laser beam for measuring. It measures the time the laser beam takes to travel from the rangefinder to the target and back. Laser reflectivity and measurement results may vary according to climatic and environmental conditions, as well as the color, surface finish, size, shape and other characteristics of the target.

The following conditions facilitate measuring:

• Cloudy weather
• Bright-colored target
• Large-size target
• When laser incidence to the target surface is straight

Measurement may be inaccurate or fail in the following cases:

Internal display

: Aim at the target you want to measure. Position the target at the center of the reticle.

: Appears while the laser is being irradiated for a measurement.
Do not look towards the objective lens side while this mark is shown.

: Now measuring

: "Failure to measure" or "Unable to measure"

* Because the internal display of this product is enlarged by the eyepiece, dust may sometimes be seen.
This will not, however, affect the measurement accuracy.

Measurement display mode

1. Turn on the power.
2. Press and hold the MODE button, then immediately press the POWER ON/ Measurement button.
3. Release your finger from the POWER ON/ Measurement button within 2 seconds to switch the Measurement display mode.
4. Repeat steps 2 and 3 to switch measurement display mode in rotation.

* If the buttons are not pressed in the correct order, switching will not take place.

Target priority mode

This Nikon Laser Rangefinder employs the First Target Priority/Distant Target Priority switching system (Factory default setting is First Target Priority mode).

1. Turn on the power.
2. Press and hold the MODE button, then press and hold the POWER ON/Measurement button. Continue to press and hold both buttons (for more than two seconds) until Target Priority modes are switched.
3. Release both buttons after the mode has switched.

* If the buttons are not pressed in the correct order, switching will not take place.

[First Target Priority mode/Distant Target Priority mode]

When measuring overlapping subjects, First Target Priority mode displays the distance of the closest subject and Distant Target Priority mode displays that of the farthest subject.

Distance display units

Measurement results are displayed in yards/meters. (Factory default setting is yard.)

1. Turn on the power.
2. Press and hold the MODE button for more than two seconds. After the display unit has switched, release the button.

Battery

1. Type of battery
   3V CR2 lithium battery x1
2. Inserting/replacing battery
   1. Open the battery chamber cover
      Rotate the battery chamber cover counterclockwise and remove it. It may not open easily due to its rubber packing for water resistance.
   2. Insert the battery/Replace the old battery with a new one
      Insert a new battery correctly positioned following the indication seal inside the chamber. The [+] pole should be positioned toward the inside of the chamber. If the battery is not inserted correctly, the Nikon Laser Rangefinder will not operate. When replacing the battery, remove the old battery then insert a new one.
   3. Close the battery chamber cover
      Rotate the battery chamber cover clockwise to screw it into the body. It may not close easily due to the rubber packing for water resistance, but continue to turn it all the way until it stops. Confirm that the cover is securely closed.
3. Battery level indicator
   * The battery condition mark in the internal display warns when the battery needs to be replaced.

4. Battery life

Continuous operation: Approx. 10,000 times (at approx. 20°C)
This figure may differ according to conditions, temperature, and other factors such as target shape, color, etc. Use only as a guide.

* The battery supplied with this Nikon Laser Rangefinder is for operation checking. Due to natural electrical discharge, the life of this battery will likely be shorter than that noted above.

* If water enters the battery chamber due to submersion, dry the battery chamber well, then replace the battery.

Measurement

Preparing

Install a battery in the battery chamber. (See "Battery")

Diopter adjustment
