Operating Instructions
1. Power On/Off
Press the power button once to turn on the rangefinder. The device will automatically power off after 20 seconds of inactivity to conserve battery life.
2. Basic Distance Measurement
To measure distance, look through the eyepiece and aim the crosshairs at your desired target. Press the power button once to activate the laser. The measured distance will be displayed on the internal LCD. For continuous scanning, hold down the power button while sweeping across multiple targets.

3. Switching Modes
The rangefinder offers multiple operating modes. To cycle through the modes, press the 'MODE' button (typically located on the side or top of the device). The current mode will be indicated on the display.

Modes of Operation
The Jiehome P81148 Golf Rangefinder features four distinct modes to cater to different measurement needs:
- Mode 1: Continuous Scan & Flag-Lock (Tournament Legal)
In this mode, the device continuously scans for targets. When the crosshairs are held over a flag, the Flag-Lock feature will activate, providing a vibration feedback and displaying the distance to the flag. This mode is legal for tournament play as it does not include slope compensation.
- Mode 2: Slope Technology + Angle + Flag-Lock
This mode calculates and displays the compensated distance, taking into account the incline or decline of the terrain. It also shows the angle of the slope. The Flag-Lock feature is active. This mode is generally not permitted in official tournaments.

- Mode 3: Horizontal Distance Measurement + Vertical Distance Measurement
This mode provides both the horizontal distance to a target and its vertical height difference relative to the user's position.
- Mode 4: Speed Mode
Utilize this mode to measure the speed of a moving object. Aim at the object and activate the laser; the speed will be displayed.
Maintenance
- Cleaning: Use the provided cleaning cloth to gently wipe the lenses and the body of the rangefinder. Do not use abrasive materials or chemical cleaners.
- Storage: Store the rangefinder in its protective case when not in use. Avoid exposing it to extreme temperatures or direct sunlight for prolonged periods.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Charge the battery using the provided USB-C cable. |
| Inaccurate distance readings. | Dirty lens, unstable aiming, or target too far/small. | Clean the lenses with the cleaning cloth. Ensure stable aiming. Target larger objects or use Flag-Lock for small targets. |
| Display is blurry. | Eyepiece diopter not adjusted correctly. | Rotate the diopter adjustment ring until the display is clear. |
| No vibration feedback. | Flag-Lock feature not activated or target not detected. | Ensure you are in a mode that supports Flag-Lock. Aim steadily at the flag. |
