1Functions
This instrument is equipped with the semiconductor diode with wavelength of 635nm, which the laser
beam has supreme visibility. And also this instrument adopts the electric self–leveling technology,
so it has large leveling range and high accuracy.
The instrument can emit four crossed vertical lasers, four horizontal laser(in the same surface) and
a down point, the cross point of four vertical lasers over the instrument is the zenith point, which
stays in the same plumb line as the down point. Emitting directions of the laser depicted as follows:

3. Directions
3.1 Battery Installation
Place 4 sections of rechargeable batteries into the battery box , then put the battery box cover onto the
battery box as the above illustration.
5
3.1.1 Charging
One battery box with 4 sections of rechargeable batteries and a charger are included in the
accessories of the instrument.
3.1.2 Charger
When the power indicator on the panel winks, the batteries need to be charged immediately. Connect
the input plug of charger with AC, and then insert the output plug of charger into the plughole of charger
box.
When the indicator on the charger lights, charging are progressing.
When the indicator on the charger winks quickly, charging has finished.
Notices:(1) Causes for charger indicator winking slowly
A: Having not inserted the output plug of charger into the plughole of the charger box completely.
B: Troubles in the connection of the output plug with the plughole of charger box, or the troubles inside the
batteries.

(2) Using the standard rechargeable batteries of the instrument, the whole course of charging
will be finished in 4 hours approximately.
(3)Power required for the charger Frequency :50-60HZ；Voltage: 85V-265V。
(4) If keeping the instrument in storage (not using for a long time), please take out the batteries
(alkaline batteries or rechargeable batteries).
(5) The brand-new or unused batteries need to be recharged or discharged for three times to acquire
the standard capacity.
3.2 Operation
3.2.1 ON/OFF
Press the key ON/OFF to make the instrument power on, and then the automatic self-leveling starts
up when the power indicator lights. At the same time the horizontal laser will be emitted.
When the power indicator winks to show the voltage of the batteries is too low. On this occasion,
7
the batteries need to be renewed.
Press the key ON/OFF again to make the instrument power off.
3.2.2 Panel Controlling
1. Press the key H after instrument is power on, and then the horizontal laser II will be emitted.
At this moment, press the key H again, all the horizontal laser go out.
2. Press the key V1 after the instrument is power on, and then the two vertical lasers of V1 direction
will be emitted; At this moment, press the key V1 again, the two vertical lasers will go out.
3. Press the key V2 after the instrument is power on, and then the two vertical lasers of V2 direction
will be emitted; At this moment, press the key V2 again ,the two vertical lasers will go out.
4. Press the key V1 or V2,the down point will light simultaneously.
5. Press the key OUTDOOR to choose the modulation of the laser. Press the key OUTDOOR after the instrument
is power on, then the lasers of the instrument will be able to be located outdoors with the detector.
Press the key OUTDOOR again to shut off the modulation of the lasers.

3.2.3 Leveling
When the instrument is placed improper or the slope of the instrument exceed the leveling range ±
4°permitted due to some other reasons, all the lasers will go out ,which show the instrument is out
of level. On this occasion, please turn around the screw of the foot under the base to adjust the slop
so that the instrument will resume the state of leveling.
