Please carefully read the safety instructions and the user manual before using this product. Keep away from children. Use the device only as specified in the user manual. The kit includes a laser receiver, bracket, lanyard, user manual, and warranty.

Getting started

Open the battery compartment cover (13) and insert the battery according to the correct polarity.
Close the cover.
Press (8) to turn the device on or off.

Usage

Place the device opposite the laser level so that the reception window (2) of the receiver is in front of the laser beam. If the LEDs in any group of three colour LED indicators (front, rear, and side) that are used for the correct installation of the device are on, the buzzer (10) will produce a sound. When the beam above the centerline indicator (3) (red LED) is on, a short pulsing sound will be heard. When the beam below the centerline indicator (5) (blue LED) is on, a long pulsing sound will be heard. Move the device downwards/upwards according to the arrow direction.

Use the bubble levels (1, 11) to level the device so that the laser beam precisely hits the reception window (2). When the laser beam is aligned with the reference centerline (6), the centerline indicator (4) (yellow LED) will be on and a steady sound will be heard. Press (9) to change the sound settings: normal → off → loud (default). The device can be mounted on a tripod or placed on a vertical or horizontal surface
