Tilting the projection plane
In the manual control mode, you can tilt the projection plane within the laser pointer self-levelling range. This can be useful when
determining low slopes/downgrades, like on driveways or ramps.
Start the product, wait for it to self-level, and then switch to the manual control mode. Use the positioning control buttons to set
the desired tilt angle.
If the tilt angle exceeds the laser pointer self-levelling range, the laser pointer stops spinning and the projected laser spots fl ash.
Press the positioning control button with the arrow in the opposite direction until the laser pointer starts spinning again.
Caution! Restarting the product after operation with a tilted projection plane may take much longer than normally. The product
needs more time to level the laser pointer.
Shock protection control
Pressing this button will switch on the shock protection feature which prevents measurement errors induced by accidental shocks
of the product. If the shock protection control fl ashes slowly, the shock protection feature has been activated and monitors the
product. When the light starts fl ashing quickly, the shock protection feature has detected a shock. The laser pointer stops spinning.
Press the shock protection control button and repeat the measurement with the reference laser lines.
Remote control
Your product includes with a remote control. Before the fi rst use, batteries must be installed in the remote control. Mind the proper
polarity of the batteries. The maximum operating range of the remote control 20 m and can be signifi cantly reduced when work-
ing outdoors. The remote control has the following control buttons: Work Mode, ROtational Speed Control, Pan Angle, Rotation
Sense Control, and Positioning Control. The remote control buttons work just the same as their counterparts on the control panel.
Laser beam receiver
The product features a laser beam receiver which detects the laser beam projected by the product, even if the laser beam is poorly
discernible with a naked eye. Before the fi rst use, batteries must be installed in the laser beam receiver. Mind the proper polarity
of the batteries. The laser beam receiver features a control panel with the following controls and indicators.
POWER: turns the laser beam receiver on and off . When powering on, the buzzer sounds and symbols appear on the control
panel display.
VOLUME: enables and disables the buzzer. The buzzer on/off status is shown on the control panel display.
BEAM: cycles between the coarse and fi ne levels of laser beam detection. Start with the laser beam coarse detection level; when
the laser beam is acquired by the receiver, switch to the fi ne level to precisely locate where the laser post is projected. The active
laser beam detection lever is shown on the control panel display.
Laser beam detector: the sensor fi eld which detects laser radiation. A line passes the middle of the sensor fi eld which shows the
highest detection precision.
Control panel display: shows the parameter settings, the battery charge status, and aids in detection of the laser beam. A display
with the same readings is also on the back panel of the laser beam receiver.
Turn on the laser beam receiver, switch on the coarse detection level and aim the laser beam receiver to have the laser beam pro-
jected on the detector. If the detector senses a laser beam, an arrow appears on the control panel display. Move the laser beam re-
ceiver in the direction shown by the arrow. When the laser beam is detected in the centre of the sensor fi eld, the arrows disappear
and the coarse detection level icon is displayed. Switch to the fi ne detection level and align the laser beam receiver slowly. If the
fi ne detection level icon appears on the control panel display, the laser beam passes right through the sensor fi eld of the detector.
The laser beam receiver features a clamp with a spirit level on the grip. The clamp facilitates fi tting the laser beam receiver to a
structure and the spirit level — to verify the level of the receiver. The laser beam receiver is mounted on the holder with a bolt
threaded directly into the threaded nut on the back panel of the laser beam detector.
Target panel
The target panel helps transfer the measured values on the wall on which a laser beam is projected and verify the measurement
accuracy of the product.
Laser goggles
Your product includes a pair of laser goggles which help fi nding the laser beams by eye. The laser goggles DO NOT protect the
eyes against laser radiation. The laser goggles DO NOT protect the eyes from foreign bodies or heat. The laser goggles may
change the perception of colours. Do not use them when driving vehicles.
Verifi cation of measurement accuracy
A verifi cation of the accuracy of the product is recommended before each use. Re-verify the product whenever it suff ers a strong
shock or falls down. Before the verifi cation, fi nd a measured distance 20 m long, free from obstructions to laser light, and located
between two parallel walls.
Mount the product on a tripod or put it on a stable, level base near one of the walls. Turn on the product and wait until the laser
pointer is automatically levelled. When the laser pointer starts to spin, mark out location "A" of the projected laser beam on the
wall closer to the product (II) or on the target panel attached to the wall.
Rotate the product 180 degrees around the vertical pivot axis on the tripod, wait until the laser pointer self-levelling is complete,
