Detecting Laser Level Signals

While detecting laser signals, the LCD will display as follows: (take
the set-up state of high sound and fine detection as an example)

When the laser signal is near the on-grade mark, the displayed up

and down arrows will decrease as the distance to the on-grade
mark decreases.

1. When detecting a horizontal laser signal, it is

important to have the bubble vial centered, as the
deflection of the receiver will influence its receiving
accuracy.

2. When detecting a vertical laser signal, it is

important to have the bubble vial centered, as the
deflection of the receiver will influence its receiving
accuracy.
