Caution!

• DO NOT use this device in an unstable situation.
• DO NOT disassemble or restructure the device. Otherwise, it may lead to laser emission resulting in unnecessary personal injury.

BASIC FUNCTION

COMMENT :

• When measuring distance within 10 m, measurement accuracy is ±2 mm. When measuring more than 10 m, measurement accuracy is calculated as follows: ±2 mm + 0.05 x (D–10). (D: Measuring Distance, Unit: m).
• When measuring too poorly reflecting targets or very rough surfaces, or if the ambient temperature is too high or too low or ambient brightness is too bright, such as under sunlight, the deviation will be unfavorable.

PROHIBITED

1. Do not attempt to disassemble or repair the device or modify it in any manner.
2. Immersing the device in water.
3. Cleaning the lens using alcohol or any other organic solvent.
4. Wiping the lens directly with fingers or other rough surfaces.
5. Powering the device beyond the rated DC voltage.

BATTERY INSTALLATION
Remove battery compartment cover and insert 2x AAA batteries (alkaline).

OPERATION

Also see figures AA to L on page 1 of this manual.

1. SWITCHING ON

   • Briefly press to switch on the device, screen will be as shown in fig. AA.
   • Then the device enters Single Measurement Mode and the laser point is opened (fig. A).
   • The laser point is automatically closed if there is no more operation after 30 seconds. Or briefly press to close the laser point (fig. B).
   • Briefly press again to open the laser point (fig. C).

2. CHANGING THE MEASUREMENT REFERENCE

   • Default measurement reference is the bottom of the device (fig. D).
   • Press and hold to change the measurement reference to the top of device (fig. E).

3. UNIT CONVERSION

   • Factory default unit is m (fig. F).
   • Press and hold to switch unit from m to ft (fig. G).
   • Press and hold once more to switch the unit from ft to in (fig. H).
     Note : Press and hold to change the unit of measurement, the value will change accordingly at the same time if there is a measurement value.  When the unit is m² , press and hold , and the unit will change from m to ft² , in. When the unit is m³ , press and hold , and the unit will change from m³ to ft³, in.When switching on the device at a later time, it will remember the last measurement unit you used.

4. CHANGING THE MEASUREMENT MODE

   • Default setting of measurement is Single Measurement Mode (fig. I).
   • Briefly press to switch to Area Measurement Mode (fig. J).
   • Briefly press once more to switch to Volume Measurement Mode (fig. K).
   • Briefly press once more to switch to Single Pythagorean Theorem Measurement Mode (fig. L).
   • Briefly press once more to switch to Dual Pythagorean Theorem Measurement Mode (fig. M).
   • Briefly press once more to switch to Historical Data Review Mode, the last measuring data will be displayed (fig. N).
     Note : At this Historical Data Review Mode, there will be some measuring data that result from factory tests. It does not mean this device has been used.

5. SWITCHING OFF

   • The device can be switched off at any time by pressing and holding .

FUNCTION DESCRIPTION

Also see figures O to X on page 1 of this manual.

1. SINGLE MEASUREMENT

   • At the Single Measurement Mode, aim the laser onto the target.
   • Briefly press . The measuring result will be displayed immediately (fig. O).

2. CONTINUOUS MEASUREMENT

   • At the Single Measurement Mode only, aim the laser onto the target.
