AOFAR HX-1100V Hunting Rangefinder User Manual

Introduction

This document provides comprehensive instructions for the AOFAR HX-1100V Hunting Rangefinder. It covers operation, specifications, safety guidelines, maintenance, and troubleshooting to ensure optimal use of the device.

Operation Instructions

Focus Adjustment

The HX-1100V rangefinder features an adjustable eyepiece with a range of +/-3 Diopters. This allows users with different vision prescriptions to observe the LCD display clearly without needing glasses. Rotate the eyepiece until the reticle and object display sharply in your vision.

Modes Memory Function

The device defaults to RANGE mode upon startup. Any operational mode selected will be remembered and retained for the next power-on after shutdown.

Functions of "MODE" Button

Units Switch

The HX-1100V can measure distances in yards or meters. The unit indicators are located in the lower right of the LCD. To switch between yards (Y) and meters (M), press and hold the "MODE" button for 3 seconds.

Modes Switch

To cycle through the available modes (Range, Speed, Scan), briefly press the "MODE" button.

Range Mode

Display

When in Range mode, the LCD displays a reticle, angle information, measured distance, and a battery indicator. Ensure the "Range" mode is active.

Operation Method

After selecting Range mode, press the "POWER" button to initiate a measurement. The laser rangefinder will automatically power off after 8 seconds of inactivity. To measure, align the aiming circle in the center of the view with a target more than 5 yards away, then quickly press and release the "POWER" button. The LCD will display the range and angle. The upper part of the LCD shows the angle of uphill/downhill shots, and the lower part displays the horizontal distance, which is the true distance.

Speed Mode

Display

In Speed mode, the "Spd" icon appears on the left side of the LCD. The display will also show speed units (e.g., m/s).

Operation Method

Aim the "POWER" button at target B and move slightly. The speed of the movement will be measured and displayed. The "Spd" indicator remains visible during measurement.

Notice: Align the aiming circle with the target until it stops flashing. The target's speed will then be obtained. The angle 'α' must be less than 10° for optimal speed accuracy; a smaller angle yields higher accuracy.

Scan Mode (Continuous Scan)

Display

In Scan mode, the "Scan" icon is displayed on the left side of the LCD. The center circle may flash during scanning.

Operation Method

To continuously scan, press and hold the "POWER" button while moving the device. The "Scan" indicator is always displayed. The angle and straight-line distance will update as the target is tracked. No compensation distance is displayed during scanning. Upon completion, the angle, horizontal distance, and straight-line distance of the last target are shown.

Tips: Scan mode is recommended for measuring targets in adverse hunting weather conditions.

Hunting Mode Instruction

This mode helps bowhunters determine the true horizontal distance to their target. For example, if the line-of-sight distance is 32 yards and the angle is -44 degrees, the true horizontal distance is 23 yards. Shooting based on the line-of-sight distance (32 yards) would result in missing the target (e.g., shooting over a deer).

Bowhunters rely on accurate horizontal distance for practice and making necessary adjustments. Understanding the difference between line-of-sight and horizontal distance is crucial for accuracy.

The perceived difference in performance for uphill vs. downhill shots is often due to the bow's sighting system, not gravity. The sighting pin on a bow is typically offset from the mechanical axis of the arrow, affecting the arrow's trajectory relative to the aiming point.

Product Specifications

Description of the Screen Display

The screen display features a central aiming reticle, distance readings (e.g., 18888), mode indicators (Scan, Spd), angle (e.g., 188.8°), and a battery status icon.

How it Works and Ranging Accuracy

The HX-1100V rangefinder emits invisible, eye-safe infrared energy pulses. Sophisticated digital technology instantaneously calculates distances by measuring the time it takes for each pulse to travel from the rangefinder to the target and back.

The reflectivity and range of a target are affected by its color, surface smoothness, size, and sharpness. Measurement accuracy can be challenging in conditions such as:

• Raining or fogging.
• Targets that are too small.
• Objects with low reflectivity (e.g., black surfaces, complex shapes, curved surfaces, water, glass, mirrors).
• Low battery power.

Components

The AOFAR HX-1100V rangefinder has the following components:

• 1. Laser transmitting objective lens: The lens that emits the laser pulse.
• 2. Laser receiving objective lens: The lens that receives the reflected laser pulse.
• 3. Modes/Units switch button: Used to switch between measurement modes (Range, Speed, Scan) and units (Meter/Yard).
• 4. Power/Reading button: Used to turn the device on/off and initiate measurements.
• 5. Rotary focusing: Allows adjustment of the eyepiece for clear vision.
• 6. Battery cap: Covers the battery compartment.

A diagram shows the device with these components labeled numerically.

Getting Started (Inserting the Battery)

To insert the battery:

1. Remove the battery cap by rotating it counter-clockwise.
2. Insert a CR2-3V battery, ensuring the negative pole (-) is placed into the battery compartment first.
3. Replace the battery cap by tightening it clockwise.

Note: It is recommended to replace the battery once every 12 months.

Notice: Replace the battery when the low battery indicator shows. If the " " symbol (representing low battery) displays and flashes on the LCD, the 3-volt lithium battery should be replaced.

Battery Indicator Levels:

• Full Bars: Sufficient power available.
• Partial Bars (e.g., 60%): 60% power left.
• Flashing Low Battery Icon: Low battery indicator flash: Replace the battery now!

⚠️ Warning

Attention!

• It is normal for the lens to become wet when temperature changes suddenly. In this situation, remove the battery and do not use the device until it is completely dry.
• Moving the device from a cold place to a warm room may cause condensation on the appearance and internal parts. To prevent this, place the device in a waterproof plastic bag and remove it only after its temperature has gradually increased.
• To avoid failures, do not store the product in:
  1. Unventilated and humid places.
  2. Cars or trunks exposed to the sun.
  3. Environments with humidity over 90%.

Please do not preserve or place the lens under the sun! Its radiation convergence function can harm the LCD.

Lithium Battery Precautions

• To prevent leakage, heat, and fire.
• Do not disassemble or modify the product yourself.
• Do not throw the battery into fire or store it in high temperatures.
• Avoid direct contact with metal objects such as coins or keys.
• If skin touches leaked liquid accidentally, rinse immediately with cool water. If eyes or mouth touch leaked liquid, do not rub; rinse with cool water and consult a doctor.
• Keep batteries out of reach of children.
• Observe local policies for the proper disposal of used lithium batteries.

Maintenance of the Instrument

Gently wipe the surface of the lens with a clean, soft cloth to remove stains that could cause damage. If stains are present on the lens surface, they may damage the lens. Avoid touching the lens with your fingers to protect its coating.
