Frequently Asked Questions - RangeXtender G 30 Laserliner

How to install the battery in the RangeXtender G 30 laser receiver?

Open the compartment on the back of the housing and insert a 9V battery (type 6LR61) observing polarity. Close the cover.

What is the maximum range of the receiver?

The maximum range is 30 meters with a compatible GRX-READY laser. The minimum distance to the laser is approximately 3 meters.

How to use the receiver with a surveying rod?

Attach the receiver to a mireflexi (not supplied) using the universal bracket. The mireflexi allows direct reading of height differences without calculations.

What does the audible signal mean and how to activate/deactivate it?

The audible signal indicates the laser position. Press the F button (On/Off) to turn on the device; the G indicator lights up. The audible signal is enabled by default. To disable it, refer to the detailed manual.

What is the purpose of the tolerance range adjustment?

The H button switches between two modes: precision range (LED off) for fine leveling, and freehand range (red LED) for less demanding tasks. Adjust according to your needs.

How to interpret the position display LEDs?

The LEDs on the receiver indicate the laser position: center LED on = perfect alignment; top or bottom LED = offset. Move the receiver until the center LED lights up.

Does the device turn off automatically?

Yes, the receiver turns off automatically after 5 minutes if no display change is detected, to save battery.

What precautions should be taken with strong magnets?

Magnets can affect pacemakers and damage magnetic media. Maintain a distance of at least 30 cm from implants and sensitive devices.

How to clean the laser receiver?

Use a soft, dry cloth. Do not use solvents or water. Store the device in a clean, dry place (0°C to 70°C, max 80% RH).

What to do if the receiver does not detect the laser?

Check that the laser is in manual receiver mode (high-frequency pulses). Ensure the distance is between 3 and 30 meters and that the battery is sufficiently charged. Avoid reflective surfaces that can distort detection.

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 passed on together with the device.

Function / application

Laser receiver for all green line lasers with GRX-READY technology

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.

1 Insert battery

Open the battery compartment on the housing's rear side and insert a 9 V battery. Correct polarity must be observed.

2 GRX READY Working with the laser receiver GRX

Use the laser receiver GRX for levelling over longer distances or when the laser lines are no longer visible. Switch on with button F; control lamp G will light up.

Line lasers: This button switches hand receiver mode on and off.

GRX 30: This button is used to establish the tolerance range.

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 30 m. Minimum distance from the laser device about 3 m.

Now move the receiver field (B) of the laser receiver through the laser lines upwards and downwards (horizontal laser line) and/or sideways (vertical laser line) until the centre LED lights up. Now mark the horizontal and/or vertical reference dimension.

Laserliner

Minimum distance from the laser device about 3 m. 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.

Used with levelling staff

The laser receiver GRX 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.

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.
