manual before operation. Improper operations without complying with this
manual guide could cause damage to the device, influence measurement results,
or bodily injury to the user.  
The Instrument is not allowed to be disassembled or repaired on anyways. It is
forbidden to do any illegal modification or performance change for laser
emitters. Please keep it out of reach of children and avoid **use** by any
irrelevant personnel.

It is strictly prohibited to shoot eyes or other parts of the body with the
laser; it is not allowed to take the laser to shoot any objects’ surface with
strong reflecting.

####  Operation instructions

##### Tum on & off

Long press to turn on  
Long press to turn off.

##### Single measurement

Pressure turn on the laser and Press again, the result will display on the
screen.

#####  **Continuous measurement**

Long press 2s to go in, the MAX & MIN will show. Press or to quit. Besides, it
will stop if no operation after 3mins.

#####  **Area measurement**

Press to go in when the testing mode is in Single measurement and Press to get
the length & width, then it will work out the area on the screen.

#####  **Volume measurement**

Press to go in when the testing mode in Area measurement, and Press to get the
length & width & height values, then it will work out the volume on the
screen.

#####  **Pythagorean measurement**

Press to go in when the testing mode in Volume measurement, then press to get
the 0 & 0 values, it will work out the height “L” on the screen.

#####  **Secondary Pythagorean measurement** “ ****

Press to go in when the testing mode in Pythagorean measurement, then press to
get the ® & 0 & 0 values, it will work out the height “L” on the screen.

##### Secondary Pythagorean measurement “ **** “

Press to go in when the testing mode in Pythagorean measurement, then press to
get the 1 & 2 & 3 values, it will work out the height “L” on the screen.

##### Level measurement (Except NE-271)

Pres to go in when the testing mode in Pythagorean measurement 2, then press
to get the 1, it will automatically calculate the angle degree between the
hypotenuse and the horizontal edge, vertical Length “H” and horizontal length
“L”.

##### Vertical measurement (Except NF-271)

Pres to go in when the testing mode in Level measurement, then press to go in,
then press to get the 1 & 2 lengths, it will work out the degree “0” and
length “L”.

##### Addition & subtraction measurement

Under the Single, Area, Volume measurement mode, press to get a result “A”,
then press “(+)” or ” (-)”, press again to get another result “B”, then it
will automatically calculate the value (“A+B “or “A-B”).

##### Unit switching

Long press 2s to switch the unit, optional from (0.000m—)0.00m—0.00ft—)
0’00″%—0.0in-00%in)

##### Benchmark switching

Press to go in, you can set the benchmark to measure from the front side 1, or
from the end side 2.  
Unit switching

Press to go in, you can query the data measured before. Then press or to quit.

##### Setting
