finish leveling.
(2) If the instrument is placed improperly, or the slope of instrument exceeds the
range from -5° to +5°, the mode indicator and the laser beam will wink at the
same time. Then place the instrument properly.
2.3.3 Spinning
(1) Change speed
Press the rotating speed button to control the spinning speed of the laser head.
If press the key repeatedly, the spinning speed of the laser head will
continuously change as follows: 0-60-120-300-600-0 r.p.m.
(2) Stepping spinning
Locate the Key Speeding-up at 0 r.p.m., The laser head will stop spinning.
And press the Key Right- spinning, the laser head will step-move clockwise.If

then press the key Left-spinning, the laser head will step-move
counter-clockwise.
2.3.4 Directional scanning
(1) Press the Key Directional scanning: the laser head will scan directionally. If
press the key repeatedly, the angle of scanning of laser head will continuously
changes as follows: 0, -10°, -45°, -90°, -180°, -0°
(2) Press the Key Left-spinning or the key Right-spinning to change the direction
of scanning.
2.3.5 Slope Adjustment
Press the remote Key Manual/Automatic when mode indicator lights, the instrument
enters the mode of manual leveling.
(1) Slope of X-axis

Aim the X1-beam to the direction of the slope required to adjust, as depicted
below.
Press the key ← or → to move the laser beam up or down.
(2) Slope of Y-axis
Aim the Y1-beam to the direction of the slope required to adjust.
Press the key ↑ or ↓ to move the laser beam up or down.
(3) Press the key Manual/Automatic again
when mode indicator goes out, the
instrument will enter mode of
automatic leveling.

3. Recharge battery
(1) When the batteries needs to be charged, connecting the charger with AC.
Insert the plug of charger into the plug hole at the bottom of the instrument
(As depicted below).
(2) If the indicator of charger lights, it shows the batteries are being charged.
(3) If the indicator light of the charger winks, it shows the course of recharging
has ended.
Notices:
1. Using the standard rechargeable batteries of the instrument, recharging will be

finished within 7 hours.
2. Power required for the charger: Frequency: 50-60HZ; Voltage: 85-265V.
3. Charging and using of the instrument can progress simultaneously.
4. If keeping the instrument in storage (or Leave the instrument unused for a long
time), the batteries (dry battery or rechargeable battery) needs to be taken out.
5. Brand-new rechargeable batteries or long-time unused rechargeable batteries
need to be recharged and discharged three times to attain the capacity required.

4. Accuracy Checking
4.1 Horizontal-surface Checking
(1) Place the instrument at the point of 50m in front of wall (or set a scale plate at
the point of 50m away from the instrument), and then adjust the level of the
base approximately to aim the X1 to the wall (or scale plate), as depicted
below:

(2) After switching on the power, use the laser detector measuring the h1 of
X1-beam on the wall or scale plate.
(3) Loose the screw of the tripod, and then turn around the instrument 180° to
measure the h2 of X2-beam on the wall or scale plate.
D-value between h1 and h2 ought to be less than 10mm
(4) Check the Y-beam in the same way.
4.2 Horizontal-line Checking
(1) Place the instrument between two walls with the distance of 30m (or two scale
plates with the distance of 30m)
(2) Place the instrument according to horizontal setting and then adjust the
instrument.

(3) Switch on the power, and then measure the middle point of the laser beam on
the wall (or scale plate):hA, hB and hA’ , hB’
(4) △1=hA-hA’ , △2=hB-hB’
D-value between △1 and △2 ought to be less than 6mm

Diameter: 500m (Using the laser detector)
Remote controlling Distance
DC 4.8-6V (NI-MH rechargeable)
-20°C~+50°C (-4°F~+122°F)

6. Detector
The Universal Laser Detector
aids in locating and targeting a
visible or invisible beam emitted
by a rotary laser; perfect for use
in outdoor conditions, where
sunlight and distance may make
locating the beam more difficult.
The laser detector includes a rod
clamp which allows to mount the
detector onto square, round or
oval sighting rods.

6.1 Operation instrument
(1) Mount the instrument onto a sighting rod if you are using one. Turn on the
instrument by pressing the ON/OFF pad. The LCD symbols will momentarily
flash and the “coarse” beam indicator symbol will remain lit and the audio
signal will be on.
(2) Expose the beam capture window of the laser detector towards the direction of
the rotating laser.
(3) Slowly move the laser detector in an upward and downward direction until the
LCD beam indicator arrows appear and/or a pulsing audio signal is heard. Use
the Beam Resolution feature to choose between the coarse/low setting, used
for approximating level or for initial locating of the center level point, the
medium setting, used for greater accuracy, and the fine/high setting, used for

the most accurate pinpointing of level. (to see the available Resolutions,
please refer to the Specs Table).
(4) Move the detector upward when the low beam indicator light is lit (with
volume on, a short pulsing audio tone is heard). Move the detector downward
when the high beam indicator arrow is lit (with volume on, a long pulsing
audio tone is heard). When the beam is level, the level beam indicator line will
be lit and a solid audio tone will be heard.
(5) If the detector is not struck by a laser beam after 5-8 minutes, the detector will
automatically shut itself off to preserve battery life. Turn the instrument back
on using the power button.

7. Remote
The remote of the instrument adopts the infrared technique.
Aim the aperture of infrared ray to the instrument (as
depicted below) to bring remote controlling into function
(Available distance: 20M).
The tele controlling panel includes 9 keys; the indicator on
the device will wink to show the operating signal has been
sent out once pressing any key.
Functions fulfilled by the remote as follows:
(1) Spinning: Operating method referring to 2.3.3.
(2) Directional scanning: Operating method referring to 2.3.4.
(3) Slope adjustment: Operating method referring to 2.3.5.
