6. Place the device in the area where you want to detect laser lines.
7. The device will detect laser lines up to a maximum distance of 50 meters away.
8. The LC display will show arrow symbols and a millimeter display to indicate the height difference between the laser beam and the marking level.
9. The sound ON/OFF feature can be used to enable or disable the audible signal when laser lines are detected.
10. The device can be used with a levelling staff by fixing it to the fastening screw provided.
11. After use, turn off the device and remove the batteries for storage.
    Note: Direct sunlight can reduce the receiving range of the laser receiver. This device is intended for use with green line lasers with GRX-READY technology only.

Completely read through the operating instructions, the „Warranty and Additional Information“ booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and if the device is passed on, this document must be passed on with it.

Intended use
This laser receiver is suitable for all green line lasers with an integrated hand receiver mode (GRX-READY technology). It quickly detects laser lines up to a maximum distance of 50 metres. Arrow symbols and a millimetre display inform users of the exact height difference between the laser beam and the marking level.

General safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• The measuring tools and accessories are not toys. Keep out of reach of children.
• The structure of the device must not be modified in any way.
• Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
• The device must no longer be used if one or more of its functions fail or the battery charge is weak.

Safety instructions
Dealing with electromagnetic radiation

• The measuring device complies with electromagnetic compatibility regulations and limit values in accordance with EMC-Directive 2014/30/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.

Danger – powerful magnetic fields
Powerful magnetic fields can adversely affect persons with active medical implants (e.g. pacemaker) as well as electromechanical devices (e.g. magnetic cards, mechanical clocks, precision mechanics, hard disks). With regard to the effect of powerful magnetic fields on persons, the applicable national stipulations and regulations must be complied with such as BGV B11 §14 „electromagnetic fields“ (occupational health and safety – electromagnetic fields) in the Federal Republic of Germany. To avoid interference/disruption, always keep the implant or device a safe distance of at least 30 cm away from the magnet.

Risk of pinching! Do not reach into the clamping bracket!

Special product features and functions

• The receiver speeds up response times – rapid detection accelerates work rates.
• For many measuring tools, the key to optimum working is magnetic adhesion. This leaves the hands free to complete other tasks.
• Protection against dust and water – The laser receiver is exceptionally well protected against dust and rain.

FUNCTION

• Precision range: Display with smaller tolerance for precision alignment (e.g. levelling staff)
• Free-hand range: Display with larger tolerance for alignment by hand.
• Approximate range: Display with maximum tolerance for rudimentary manual alignment.

Insertion of batteries
Open the battery compartment (14) and insert batteries according to the symbols. Be sure to pay attention to polarity.

Working with the laser receiver

• Use the laser receiver for levelling over great distances or in very bright conditions. Switch it on with button 4.
• Set the line laser to hand receiver mode. The laser lines will now pulsate with high frequency, making the laser lines darker. The laser receiver can detect these pulsating laser lines up to a maximum distance of 50 m.
• Now move the receive field (7) on the laser receiver up and down through the laser lines until the middle LED lights up. Now mark the reference dimension.
• Pay attention that the laser lines are not reflected by reflective surfaces.
  ! Such reflections can lead to false indications.

• The light intensity of the laser lines is greatest at the centre and diminishes toward the ends. This can reduce the maximum reception range of the laser receiver.
• The laser reception range may be reduced if exposed to direct sunlight.

Used with levelling staff
The laser receiver can be fitted on measuring staffs with the universal mount. The Flexi measuring staff is always recommended when measuring from floor heights. It also allows you to determine heights directly without any need for calculation.

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.
