1. Measuring inaccuracy will increase by ± 0.25 mm in the distance measurement distance of 10-25 m. At a distance over 25 m, the inaccuracy will increase by a further ± 0.25 mm. Intensive sunlight, transparent materials (clean water or colorless glass), small reflectivity of the measured surface or large temperature differences may reduce measurement accuracy. When the temperature of the measured surface is high, inaccuracy may increase by ± 1.5-2 mm.
2. The battery lifetime depends on the quality of the batteries used, the storage/operating conditions of the device and the operating time of the device.

Safety warnings and information

• Before using this device, please read the safety instructions and the user’s manual.
• Before use, please read all operating instructions and safety directives in this user’s manual. Incorrect use and not adhering to the instructions contained in this manual may result in damage to the device, affect the measurement results or cause injury to the user.
• This device must under no condition be disassembled or modified. Any unauthorised modifications or power output changes are forbidden on laser beam transmitters. Keep this device our of children’s reach and prevent its use by any unauthorised person, including children.
• Pointing the laser beam into eyes or at other parts of the body is strictly forbidden. Pointing the laser beam at any highly reflective surfaces is not permitted. The beam may be reflected from such a surface and enter somebody’s eye. Do not view the beam using optical equipment, e.g. binoculars.
• Due to the device’s interference with electromagnetic transmissions and other equipment and devices, please do not use this device inside aircraft or in the vicinity of medical equipment. Do not use it in an environment with an explosive or flammable atmosphere.
• Do not point the laser beam at easily flammable materials and liquids.

Inserting batteries / Display / Buttons

INSERTING AND REPLACING BATTERIES

• Remove the battery compartment cover on the rear side of the device and insert the batteries so that their correct polarity is maintained. Then close the battery compartment cover.
• Only type AAA batteries with a supply voltage of 1.5 V may be used in this device.
• When not using the device for an extended period of time, remove the batteries to prevent corrosion.

DISPLAY

BUTTONS

Turning on / turning off / setting a reference point

TURNING THE DEVICE ON AND OFF

• In the off mode, press button . The device and laser will turn on simultaneously and will be ready for measurement.
• In the on mode, hold down button for 3 seconds to turn off the device. The device will automati-cally turn off after 150 seconds of inactivity.

SETTING UNITS
Press button  to reset the current units. Default value: 0.000 m
There are 6 types of units available.

SETTING A REFERENCE POINT
Press button to set the position of the reference point, i.e. define whether the measured length will include the length of the device or not. Including the length of the device when measuring distance has significance when measuring the distance between two walls. The default reference point of this device is the rear point.

Measurement modes

Note: To increase the measurement range in daylight or when the surface has poor reflective qualities, use the reflective target plate or white paper.

SINGLE LENGTH MEASUREMENT
Turn on the laser beam by pressing button in the measurement mode. Press button  again to measure a single length. The result is displayed on the main row of the display.

CONTINUOUS MEASUREMENT
Hold down button in the measuring mode to enter the continuous measurement mode. In this mode, the device continuously measures distance, whilst, in addition to the currently measured value on the main row of the display, it also displays the min./max. on the other rows. If you wish to leave the continuous measurement mode, press button .

MEASURING AREA

Press button and symbol will appear on the display. One side of the rectangle will flash on the display. When measuring area, proceed according to the instructions below:

• Press button once to measure the length of one side and then press button  again to measure the second side.
• The device calculates and displays the results on the main row of the display.
• The current length measurement is shown on the auxiliary row of the display.
• It is necessary to press button  to delete the result and to start a new measurement.
• Press button    to exit this mode.

MEASURING VOLUME
Press button twice and symbol will be shown at the top of the display. One edge of the cube will flash on the display. When measuring volume, please proceed according to the instructions below: Press button once to measure length. Press button again to measure width. Press button for a third time to measure height.
The device calculates and displays the results on the main row of the display. It is necessary to press button to delete the result and to start a new measurement. Press button to exit this mode.

PYTHAGOREAN THEOREM
The Pythagorean theorem function serves to calculate unmeasurable dimensions from measured dimensions using a mathematical algorithm in the examples provided below. On the images of each of the sub-functions the measured and calculated sides are displayed. To achieve accurate measurements and calculations, it is recommended to mount the device on a tripod.
Press button to select a mode.

1. Press button , the hypotenuse on symbol will flash. The device will calculate the second cathetus by measuring the hypotenuse and the other cathetus. Press button , measure the length of the hypotenuse (a) according to the flashing on the display. Press button , measure the length of one cathetus (b).
   The device will calculate the other cathetus (x).

2. Press button when one cathetus of symbol  is flashing. The device will calculate the hypotenuse from the measurement of two catheti. Press button  , measure the length of one cathetus (a). Press button  , measure the length of the second cathetus(b).

3. The device will calculate the length of the hypotenuse (x).

4. Press button  until the hypotenuse is flashing on the symbol  on the display. Press button , measure the length of one hypotenuse (a). Press button , measure the length of the other hypotenuse (b). Press button , measure the length of one cathetus (c). The device will calculate the cathetus length of the full line (x).

5. Press button  until one side of the hypotenuse is flashing on the symbol on the display. Press button  , measure the length of one side (a). Press button , measure the length of the middle line (b). Press button , measure the length of the other side (c). The device will calculate the cathetus length of the full line (x).

The catheti must be shorter than the hypotenuse. Otherwise, “err” will appear on the display. To ensure accuracy, make sure that all the measure-ments are made from the same point.

ADDITION/SUBTRACTION
In the single length measurement mode, this device can be used to add or subtract lengths.
Press button , the “+” symbol will appear on the main row of the display, meaning that you are entering the addition mode.
The display will show the value of the last measure-ment and the resulting sum.
Press button , the “-” symbol will appear on the main row of the display, meaning that you are entering the subtraction mode.
The display will show the value of the last measure-ment and the subtraction result.

Saving and viewing

The Save function can be used in the single length measurement mode.
SAVING MEASUREMENT RESULTS
Press button for 3 seconds, the result will automatically be saved to the internal memory of the device.

VIEWING MEASUREMENT RESULTS
Press button to view the saved data. Use button or to scroll forwards and backward. Holding down button will delete old entries.

ATTENTION
The spirit level on the device is only for indicative
(rough) measurement and any measurement inaccuracy or reduced functionality of the spirit level is not grounds for complaint. For accurate measurement, use a standard spirit level.

Error signals on the display

Some of the warning messages listed below may appear on the display:
