Safety instructions

Using class 2 lasers

Attention: Do not look into the direct or reflected beam.

If a person‘s eyes are exposed to class 2 laser radiation, they should shut their eyes and immediately move away from the beam.
Tampering with (making changes to) the laser device is not permitted.
Under no circumstances should optical instruments (magnifying glass, microscope, binoculars)

Dealing with electromagnetic radiation

The measuring device complies with electromagnetic compatibility regulations and limits in accordance with the EMC Directive 2014/30/EU which is covered by the Radio Equipment Directive 2014/53/EU.
Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference.
The measuring accuracy may be affected when working close to high voltages or high electromagnetic alternating fields.

Dealing with RF radiation

The measuring device is equipped with a wireless interface.
The measuring device complies with electromagnetic compatibility and wireless radiation regulations and limits in accordance with the RED 2014/53/EU.
Umarex GmbH & Co. KG hereby declares that the CompactCross Laser Pro radio equipment complies with the essential requirements and other provisions of the European Radio Equipment Directive 2014/53/EU (RED). The EU Declaration of Conformity can be found in its entirety at the following address: http://laserliner.com/info?an=AHV

When transporting always switch off all lasers, secure pendulum and push the ON/OFF switch (4) to the right.

Special product features

Automatic alignment of the device with a magnetically dampened pendulum system. The device is brought into initial position and aligns itself autonomously.

Transport LOCK: The device is protected with a pendelum lock during transport.

GRX-READY technology enables line lasers to be used even in unfavourable light conditions. The laser lines pulsate at a high frequency and this can be picked up by special laser receiversover long distances.

Green laser technology

Devices with PowerGreen technology feature bright green high-performance diodes that allow very good visibility of laser lines at great distances, on dark surfaces and in bright ambient light conditions.

Approx. 6 times brighter than a typical red laser with 630 – 660 nm

Overview

Laser line selection button / Hand receiver mode
LED levelling red: levelling off green: levelling on
Battery compartment (backside)
ON / OFF switch, transport retainer
Laser output windows
1/4″ tripod threads (bottom)
LED hand receiver mode

Inserting batteries

Open the battery compartment and insert batteries (2 x 1,5V LR6 (AA)) according to the symbols. Be sure to pay attention to polarity.

Horizontal and vertical levelling

Release the transport restraint, move the ON/OFF switch (4) to the left.
The laser cross will appear. The laser lines can be switched individually with the selection button.

Horizontal and vertical levelling

The transport restraint must be released for horizontal and vertical levelling. The LED (2) shows a permanent green light. The laser lines flash, the LED (2) lights red and a signal sounds when the device is outside the automatic levelling range of 4°. Position the device such that it is within the levelling range. The LED (2) switches back to green and the laser lines stop flashing (steady light).

Slope mode

Do not release transport safety, push ON/OFF switch (4) to the right. Select and switch on the laser with the selection button. Sloping planes can now be measured. This mode cannot be used to perform horizontal or vertical levelling as the laser lines are no longer aligned automatically. The LED lights constantly red.

Slope mode

Hand receiver mode
Optional: Working with the laser receiver GRX

Use an GRX laser receiver (optional) to carry out levelling at great distances or when the laser lines are no longer visible. To work with a laser receiver, switch the line laser to hand-held receiver mode by keeping button 1 (handheld receiver mode on / off) pressed. The laser lines will now pulsate with high frequency, making the laser lines darker. The laser receiver can detect these pulsating laser lines.

Hand receiver mode

Observe the laser receiver‘s operating instructions for line lasers. !

Preparing the calibration check

It is possible for you to check the calibration of the laser. To do this, position the device midway between 2 walls, which must be at least 5 metres apart.
Switch the device on (LASER CROSS ON). The best calibration results are achieved if the device is mounted on a tripod.

Mark point A1 on the wall.
Turn the device through 180° and mark point A2. You now have a horizontal reference between points A1 and A2.

Performing the calibration check
Position the device as near as possible to the wall at the height of point A1.
Turn the device through 180° and mark point A3. The difference between points A2 and A3 is the tolerance.

When A2 and A3 are more than 0.35 mm / m apart, an adjustment is necessary. Contact your authoriseddealer or else the UMAREXLASERLINER Service Department.

Checking the vertical line

Position the device about 5 m from a wall. Fix a plumb bob with a line of 2.5 m length on the wall, making sure that the bob can swing freely. Switch on the device and align the vertical laser to the plumb line. The precision is within the specified tolerance if the deviation between the laser line and the plumb line is not greater than ± 1.75 mm.

Checking the horizontal line

Position the device about 5 m from a wall and switch on the cross laser. Mark point B on the wall. Turn the laser cross approx. 2.5 m to the right and mark point C. Check whether the horizontal line from point C is level with point B to within ± 1.75 mm. Repeat the process by turning the laser to the left.

Regularly check the calibration before use, after transport and after extended periods of storage.

Data transfer

This device has digital connectivity which allows wireless data transfer to mobile devices such as smart phones or tablets with a wireless interface.
The system prerequisites for a digital connection are specified at
http://laserliner.com/info?an=ble
This device can generate a wireless connection to devices which are compatible with the wireless standard IEEE 802.15.4. The wireless standard IEEE 802.15.4 is a transfer protocol for Wireless Personal Area Networks (WPAN). The range is set to a maximum distance of 10 m from the terminal device and greatly depends on the ambient conditions such as the thickness and composition of walls, sources of interference as well as the transmit / receive properties of the terminal device.

The digital connection is activated as soon as the device is switched on as the wireless system is designed to use very little electricity. A mobile device can link up to the active measuring device via an app.

Application (app)

An app is required to use the digital connection. You can download the app from the corresponding stores for the specific type of terminal device:

Make sure that the wireless interface of the mobile device is activated.

After starting the app and activating the digital connection, a connection can be set up between a mobile device and the measuring device.
If the app detects several active measuring devices, select the matching device.
This measuring device can be connected automatically the next time it is switched on.

Additional functions via the app

The app offers a range of additional functions. If it is not possible to control your device via the app for technical reasons, reset the device to the factory settings by switching it off and back on again so that you can continue to use the regular functions without problems.

Information on maintenance and care

Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.

Calibration

The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year.
