2. Safety Information

Please read and understand all safety warnings before using the device.

• Laser Safety: This device uses a Class 1 laser product. Do not stare directly into the laser beam or aim it at others.
• Eye Protection: Avoid direct eye exposure to the laser.
• Environmental Factors: The device's accuracy can be affected by environmental conditions such as rain, fog, or glass. Do not attempt to measure through glass as it refracts the laser light.
• Battery Handling: Use only the specified CR2-3V battery. Ensure correct polarity when inserting. Dispose of used batteries responsibly.
• Maintenance: Do not attempt to disassemble or repair the device yourself. Refer to qualified service personnel for repairs.

5.2 Measurement Modes

The Nohawk Laser Range Finder offers several measurement modes. Press the "Mode" button to cycle through the available modes.

Figure 6: Overview of available measurement modes.

5.2.1 Single Ranging Mode

For basic distance measurement. Aim at the target and press the "Start/Measure" button. The distance will be displayed.

5.2.2 All-in-One Mode (Angle/Height/Horizontal Distance)

This mode provides angle, height, horizontal distance, and straight-line distance. Aim at the target and press the "Start/Measure" button.

Figure 7: All-in-one mode display.

5.2.3 Scan Mode

Allows continuous measurement of multiple targets by panning the device across the scene while holding down the "Start/Measure" button.

5.2.4 Two-Point Height Measurement Mode

Measures the height difference between two points. Follow on-screen prompts to measure the base and top of an object.

5.2.5 Speed Measurement Mode

Measures the speed of a moving object. Aim at the moving object and follow the instructions on the display.

5.2.6 Golf Mode (with Flagpole Lock, Slope Compensation, Vibration)

Designed for golf, this mode automatically calculates elevation and provides adjusted distances. It features flagpole locking with a vibration prompt when the flagpole is successfully locked (available on NKG models). Other models (NK, A2, NF) may have golf mode without vibration.

5.2.7 Data Storage Function (on applicable models)

Some models include a data storage function that can store previous measurements. If you are repeatedly checking stored information and it seems incorrect, ensure you are performing a new measurement rather than recalling old data.

6. Maintenance

• Cleaning: Use the provided cleaning cloth to gently wipe the lenses and exterior of the device. Do not use abrasive materials or harsh chemicals.
• Storage: When not in use, store the rangefinder in its carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery: Remove the battery if the device will not be used for an extended period to prevent leakage.
• Water Resistance: The device has an IP54 protection class, meaning it is protected against dust and splashing water. It is not designed for submersion.

7. Troubleshooting

• Inaccurate Measurements:
  • Ensure there are no obstructions (like glass) between the rangefinder and the target. Glass refracts laser light and affects accuracy.
  • Rainy, foggy, or cloudy conditions can affect maximum range and accuracy due to laser refraction.
  • Make sure the target is within the specified measurement range of your model.
• Device Not Powering On:
  • Check if the CR2-3V battery is correctly installed with proper polarity.
  • Replace the battery if it is depleted.
• Display Issues:
  • Adjust the eyepiece focus for clarity.
  • Ensure the lenses are clean.
• Memory Storage Confusion (on applicable models):
  • If your model has a memory storage function, it will store previous measurements. If you are repeatedly checking stored information and it seems incorrect, ensure you are performing a new measurement rather than recalling old data.

8. Specifications

Specifications may vary slightly depending on the specific model (NK, A2, NKG, NF) and measurement range (600m, 1000m, 1800m).

10. User Tips

• Optimal Accuracy: For the most accurate readings, ensure a clear line of sight to your target. Avoid measuring through glass or in heavy rain/fog.
• Battery Life: The smart energy-saving feature helps prolong battery life by automatically shutting down the device after 26 seconds of inactivity.
• Versatile Use: The rangefinder is suitable for various activities including golf, hunting, outdoor travel, electricity surveys, and building construction.
• Understanding Display: Familiarize yourself with the display icons and readings for different modes (e.g., angle, height, horizontal distance, adjusted distance in golf mode).
