Introduction

These

series

products

adopt

diode

laser

beam

, 

the

waveform

length

of

which

is

635nm

. 

The

laser

level

can

generate

two

or

more

laser

sectors

and

one

plump

down

point

. 

The

sector

is

formed

by

one

horizontal

beam

and

one

or

more

vertical

beams

that

is

reflected

on

the

wall

. 

The

included

angle

of

every

two

vertical

beams

is

90

˚. 

The

focus

of

those

beams

is

called

Zenith

.

Automatic self-leveling

Indoor and outdoor(long distance) mode 

360˚ rotatable ; Adjustable structure for accurate targeting 

Water-proof, dirt-proof, sensitive buttons

Operation

instructions

1

. 

Place

the

device

on

a

tripod

or

a

flat

surface

. 

Ensure

the

device

is

approximately

on

horizontal

level

Note

: 

If

the

device

is

out

of

level

, 

the

laser

will

be

shut

down

automatically

with

audio

alert

.

2

. 

Rotate

the

power

switch

clockwise

to

turn

on

the

device

. 

Laser

beams

are

emitted

with

the

green

LED

ON

. 

3

. 

Rotate

the

device

to

make

the

laser

beam

pointing

at

the

    target

.

4

. 

Turn

the

thumb

screw

to

locate

the

exact

position

. 

5

. 

After

every

task

, 

turn

the

power

switch

anticlockwise

to

turn

off

the

device
