Voice-Based Measurement Methods

• Press the power/measurement button to turn on the device ensuring the device is powered on by checking the viewfinder and giving the voice commands according to the measurement content.
• You can use voice commands to initiate measurements, helping to reduce hand movement and ensure smoother measurements.

Voice Commands for Measurements:

The voice instructions for measurement are as follows:

Note:
After ensuring the device is powered on (by checking the viewfinder), take a moment and clearly speak the voice command for smooth measurement.

Turning Height Difference Measurement O N /O FF

Height Difference Measurement OFF
When participating in competitions or events where slope measurement is not allowed, you can turn this feature off. To do so, while the device is powered on, press and hold the mode button for approximately 3 seconds. The slope and reference distance display will be hidden.

Note: The LED indicator will turn on when slope measurement is OFF, signaling that slope is not being measured.

Height Difference Measurement ON
To turn the slope measurement back on, press and hold the mode button for about 3 seconds while the device is powered on. The slope and reference distance markers will be displayed again.

Note: The device is set to have slope measurement ON by default when shipped. When slope measurement is ON, the LED indicator will be off.

Reference Distances
When hitting uphill or downhill shots, the distance you need to hit will differ from the straight-line distance to the pin due to elevation changes. This product automatically calculates and displays both the straight-line distance (AC) and the reference distance to the shot (AB) based on the slope.

Uphill Example:

• If you hit based on the straight-line distance (AC = 148 yards), your ball won’t reach the pin because of the uphill slope. To reach the pin, you’ll need to hit based on the horizontal distance (AB = 159 yards). The product will automatically display both AC (straight-line distance) and AB (reference distance to hit).

Downhill Example:

• If you hit based on the straight-line distance (AC = 148 yards), your ball will overshoot the pin due to the downhill slope. To reach the pin,
• you’ll need to hit based on the horizontal distance (AB = 141 yards). The product will automatically display both AC (straight-line distance) and AB (reference distance to hit).

Note: When slope measurement is OFF, reference distance and slope markers will not be displayed.
