5. Setup
5.1. Charging the Battery
The Mileseey PF3H comes with a built-in rechargeable lithium battery. Before first use, or when the battery indicator shows low power, charge the device using the provided USB cable.
- Locate the USB charging port on the device.
- Connect the small end of the USB cable to the rangefinder's charging port.
- Connect the larger end of the USB cable to a standard USB power adapter (not included) or a computer's USB port.
- The battery indicator will show charging status. Once fully charged, disconnect the cable.
5.2. Initial Power On
Press the 'SCREEN ON/OFF' button to power on the device. The display will light up, indicating it's ready for use.
6. Operating Instructions
6.1. Basic Distance Measurement
- Power on the device.
- Look through the eyepiece and aim the crosshairs at your target.
- Press the measurement button (usually the power button or a dedicated 'M' button) once.
- The distance to the target will be displayed on the screen.
6.2. Slope Compensation (PF280 Pro / PF3H)
The PF3H model features a special angle switch design to enable or disable slope compensation. This is crucial for golf tournaments where slope-adjusted distances are not permitted.
- To enable slope compensation, slide the switch to the 'SLOPE ON' position. The device will calculate and display the slope-adjusted distance.
- To disable slope compensation, slide the switch to the 'SLOPE OFF' position. The device will display the actual linear distance, making it legal for tournament play.
6.3. Golf Scanning & Flagpole Lock
This mode helps you quickly and accurately measure the distance to the flagpole, even with background objects.
- Activate Golf Scanning mode (refer to your device's specific button layout for mode switching).
- Scan the area around the flagpole. The device will automatically identify and lock onto the flag, excluding other objects.
- A vibration alert (PF280 Pro only) will confirm the lock, and the distance will be displayed.
6.4. Other Measurement Modes
The PF3H supports various measurement modes. Cycle through modes using the 'MODE' button (if available) or by following the specific instructions for your model variant.
- Speed Measuring Mode: For measuring the speed of moving objects.
- Point-to-Point Ranging Mode: For measuring distances between two points.
- Distance Height Angle Measurement: For calculating height and angle to a target.
