Introduction
The Bosch LR 6 Line Laser Receiver is designed to enhance the functionality of the GCL 2-160 Self-Leveling Cross-Line Laser by extending its detection range and improving visibility in various conditions. This receiver facilitates line laser detection up to 165 feet, making it suitable for outdoor use, bright environments, or when the laser beam is not directly visible on a surface.
Key features of the LR 6 receiver include dual-sided LED arrow indicators for clear visual feedback, a volume-adjustable audio signal for precise on-grade positioning, and an accuracy button for fine or coarse adjustments. For versatile mounting, the unit incorporates built-in heavy-duty magnets for attachment to metal surfaces and includes a quick-release mounting bracket for secure assembly, particularly on leveling rods.

Setup
1. Battery Installation
The BOSCH LR 6 receiver requires two (2) AAA batteries for operation. These batteries are typically included with the product.
- Locate the battery compartment cover on the rear of the receiver.
- Open the battery compartment cover.
- Insert two AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
2. Mounting the Receiver
The LR 6 receiver offers multiple mounting options for various applications:
- Using the Quick-Release Mounting Bracket:
The included quick-release mounting bracket allows for easy and secure attachment to a leveling rod or similar support. Simply slide the receiver into the bracket until it clicks into place. The bracket can then be clamped onto the desired surface.
- Using Built-in Magnets:
The receiver features heavy-duty magnets on its side, enabling direct attachment to metal surfaces. This is particularly useful for applications such as suspended-ceiling installations or attaching to metal studs.

Operating Instructions
1. Powering On/Off
Press the red power button (marked with an 'I' inside a circle) located on the front of the receiver to turn the unit on or off.
2. Detecting the Laser Line
Position the LR 6 receiver in the path of the laser line from your compatible Bosch GCL 2-160 laser. The receiver can detect the laser line up to 165 feet away.
- Visual Indication: The dual-sided LED indicators will guide you to the laser line.
- An upward-pointing red arrow indicates the receiver is below the laser line; move the receiver up.
- A downward-pointing red arrow indicates the receiver is above the laser line; move the receiver down.
- A green LED light indicates the receiver is precisely on the laser line.
- Audio Indication: The receiver provides an audible signal to assist in locating the laser line.
- A slow beeping sound indicates the receiver is approaching the laser line.
- A continuous tone indicates the receiver is precisely on the laser line.
- A fast beeping sound indicates the receiver is moving away from the laser line.
3. Adjusting Audio Volume
Press the speaker icon button on the front of the receiver to cycle through different audio volume levels or to mute the audio signal. Adjust the volume to suit your worksite environment.
4. Adjusting Accuracy (Fine/Coarse)
Press the accuracy button (marked with two horizontal lines and arrows) to switch between fine and coarse detection modes. The fine mode provides higher precision for critical alignment tasks, while the coarse mode allows for quicker detection over larger tolerances.

Maintenance
Proper maintenance ensures the longevity and accuracy of your BOSCH LR 6 Laser Receiver.
- Cleaning: Regularly wipe the receiver with a soft, damp cloth. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the plastic housing and display.
- Storage: When not in use, store the receiver in its original packaging or a protective case in a dry, dust-free environment. Remove batteries if the device will not be used for an extended period to prevent leakage.
- Avoid Extreme Conditions: While the LR 6 is IP54 rated for splash water and dust protection, avoid prolonged exposure to extreme temperatures, direct sunlight, or excessive moisture.
- Handle with Care: Despite its robust construction, avoid dropping the receiver or subjecting it to strong impacts, which could affect its internal components and calibration.
