• Place the unit in a horizontal position.
• Make sure the receiving window (on front of detector) is facing

the laser and is receiving the laser signal.

- If the LCD shows a “left” arrow and emits rapid

sounds, this indicates that the laser signal is
located to the right of the detector (Fig. 14).

- If the LCD shows a “right” arrow and emits

slow sounds, this indicates that the laser signal
is located to the left of the detector (Fig. 15).

- If the LCD show the “center” mark and emits a

continuous sound, this indicates that the laser
signal is located in the center position on the
detector.
