Operating Instructions
Powering On/Off
To power on the device, press the main power/measurement button briefly. The display will illuminate. The device will automatically power off after a period of inactivity to conserve battery.
Taking a Measurement
Single Measurement: Aim the reticle at the target and press the power/measurement button. The distance will be displayed instantly.
Scan Mode: Press and hold the power/measurement button. The device will continuously measure distances as you pan across multiple targets. Release the button to stop scanning.
Display Settings
The Helia Mono LRF 7x25 features a premium-quality OLED display.
Brightness Adjustment: Use the mode/menu button to cycle through five manual brightness settings to suit ambient light conditions.
Unit Selection: The display can show measurements in meters or yards. Refer to the device's menu system (accessed via the mode/menu button) to switch between units.
Enhanced Angle Compensation (EAC)
The patented EAC function provides angle-corrected distance measurements, which is crucial for accurate targeting in varied terrain. This function is automatically applied or can be toggled via the menu, depending on the specific firmware version. Consult the on-screen prompts or menu options for details.
Maintenance and Care
Cleaning
Lenses: Use a soft, lint-free cloth specifically designed for optics. Gently wipe the lens surfaces. For stubborn dirt, use a small amount of lens cleaning fluid applied to the cloth, not directly to the lens.
Body: Wipe the device body with a soft, damp cloth. Avoid abrasive cleaners or solvents.
Storage
Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
Battery Replacement
Replace the CR2 battery when the low battery indicator appears on the display or when the device fails to power on. Follow the battery installation steps outlined in the Setup section.
