басыңыз Кубат/Старт баскычы once to power on the device. The device will automatically power off after a period of inactivity to conserve battery.
Switching Measurement Units (Yards/Meters)

Өлчөө режимдери
басыңыз Режим баскычы repeatedly to cycle through the available measurement modes:
- Straight Distance Mode (Mode 1): Бутага чейинки түз көрүнүү сызыгындагы аралыкты өлчөйт.
- Golf Flag Locking Mode (Mode 2) with Vibration: Designed for golf, this mode helps lock onto the flagpole. Once locked, the device will vibrate to confirm the measurement. Supports distances up to 150 yards for flagpole locking and 300 yards for general flag distance.
- Slope Compensation Mode (Mode 3): When the slope switch is ON, this mode calculates and displays the adjusted distance, taking into account the incline or decline to the target. This provides a more accurate 'plays like' distance for golf.
- Horizontal and Height Ranging Mode (Mode 4): Measures both the horizontal distance and the vertical height difference to the target.
- Speed Measuring Mode (Mode 5): Кыймылдуу объекттин ылдамдыгын өлчөйт.
- Continuous Scan Measurement Mode (Mode 6): Allows for continuous scanning of multiple targets to get distances quickly.
Using Slope Compensation
The FR20 features a physical slope switch. Slide the switch to the ON position to enable slope compensation. When enabled, the device will provide an adjusted distance that accounts for elevation changes, which is crucial for accurate club selection in golf. For tournament play, ensure the slope switch is in the OFF position to comply with rules.

Flag-Lock with Vibration
In Golf Flag Locking Mode (Mode 2), aim the crosshairs at the flag. The device will intelligently lock onto the flag, ignoring background objects, and provide a short vibration to confirm the measurement. This ensures you get the precise distance to the pin.
