How to Use
Measuring
Switching mode
1. Once the laser measure is turned on, press the power/measure button to
continuously emit laser light for constant measurements. The display will show
the measuring values in real-time.
2. Press the power/measure button again to stop emitting laser light and the display
will show the final measuring value. Once the laser measure is connected to the app,
this measuring value will be synchronized to the measurement list in the app.
3. The laser measure is generally used indoors. It is not suitable for outdoor use
because the sunlight interferes greatly with the laser light, and the measurement
accuracy will decrease significantly if you cannot see the red dot of the laser
light clearly.
4. This laser measure has two measuring modes based on different original points of
the measurement. When using the front-based mode, the measurement range doesn't
include the length of this laser measure. When using the rear-based mode, the length of
the laser measure, which is 80 mm, will be included in the measurement range.
Turning on/off
Turning on: When the laser measure is off, press
and hold the power/measure button for at least 2
seconds to turn it on. The display will light up,
which indicates the laser measure is ready to
take a measurement.
Turning off: When the laser measure is on, press
and hold the power/measure button for 3 seconds
to turn it off.
If no operation is made to the laser measure
within 180 seconds, it will automatically turn off.

Each time the laser measure is turned on, it will be reset to the rear-based mode "
".
The default mode for this laser measure is the rear-based mode " ", which means
the original point of the measurement is the rear end of the laser measure.
To switch to the front-based mode " ", double press the power/measure button.

measure. Properly store the laser measure and keep it out of reach of children and
unrelated people.
Do not point the laser light at your eyes and other body parts or those of other
people. Never aim the laser light at the surfaces of highly reflective objects.
Do not use the laser measure near aircraft or medical equipment, or use it in a
flammable or explosive environment, because the electromagnetic radiation of this
laser measure may interfere with other devices.

waste. Dispose of them per national or local laws and regulations.
Warnings
Warnings!
Resetting
When the laser measure is on/off, press and hold the power/measure button for 7
seconds. The display will blink twice and the laser measure will be restored to the
factory settings.
Read the safety and operating instructions carefully before using the laser
measure for the first time.
Charging
A type-C charging cable is provided.
If the laser measure hasn't been used for an extended period, fully charge it
before use.
The laser measure cannot be used for measurement during charging.

Do not store or use the laser measure for a long time in places where the
temperature or humidity is high. When planning not to use the laser measure for a
long time, store it in environments with normal ambient temperatures and
humidity, and charge the laser measure every 6 months.
Keep the surface of the laser measure clean. Dust can be wiped away from the
surface with a soft, damp cloth, and do not use corrosive liquids to clean the laser
measure. You can wipe the laser emitting lens and the laser reception lens clean in
the same way as you wipe the optical devices.

*To measure the minimum value of the measurement range, use the front-based mode.
* "D" refers to the actual distance in an indoor environment with standard reflective
surfaces.
The measuring values may be inaccurate if the laser measure is used in the following
conditions: extremely strong sunlight, erratic fluctuation of ambient temperature,
weak reflection effect of the target surface, and low battery level. In this case, you
can use the laser measure with a reflective board for a more accurate result. Besides,
the following situations may also affect the measurement accuracy: object lenses or
the laser tube are blocked; the measurement target is not clear, such as when
measuring water surface, glass, or mirror; the laser light jitters during measurement
and so on.
