How do I get my laser to show distances in the different modes?

Continuous Scan Mode - M1

Hold down the POWER button while scanning, the data on the LCD screen will change as you move and change target.

Golf Mode - M2
Press the POWER button once while aiming the laser at a target. The laser will vibrate when it has locked onto the target. If slope is enabled the slope adjusted distance will be shown at the bottom of the display.

Speed Mode - M3

Hold down the POWER button while scanning, the data on the LCD screen will show the speed that object is moving.
