3.3. REC 300 Digital Receiver
The REC 300 Digital Receiver extends the working range of the laser up to 2624.67 feet (800m) in diameter, providing precise digital readouts for accurate height determination.
4. Setup
4.1. Battery Installation
The LAR350 laser unit requires 2 x D 1.5 V batteries. The REC 300 receiver and RC-LAR350 remote control require 4 x AA 1.5 V batteries. Ensure correct polarity when inserting batteries.
4.2. Mounting the Laser
Mount the LAR350 laser unit securely onto the provided Stabila 07498 Fixed Head Tripod using the 5/8" - 1 tripod thread. Ensure the tripod is stable on a firm, level surface.
4.3. Power On and Self-Leveling
Press the power button on the LAR350 unit. The laser will automatically begin its self-leveling process. The unit can self-level on surfaces up to +/-5 degrees out of level. LED indicators will assist in confirming the leveling status. Wait for the laser to stabilize before beginning operations.
5. Operating Instructions
5.1. Horizontal Leveling
For horizontal leveling, place the LAR350 unit on a stable surface or tripod. Power on the unit. Once self-leveled, the rotating laser beam will provide a precise horizontal reference plane.
5.2. Vertical Leveling and Plumb Lines
To achieve vertical leveling or plumb lines, position the laser unit on its side or use the vertical mounting accessory (if applicable). The laser will project a vertical plane and/or plumb points.
5.3. DUAL SLOPE Function
The DUAL SLOPE function allows for controlled inclination settings of up to 5 degrees on two axes. This is ideal for applications requiring a specific grade, such as driveways or drainage lines.

5.4. SECTION MODE
SECTION MODE allows you to limit the working area in rotation mode. The laser beam will only be emitted in a defined area, preventing interference with other equipment or personnel.
5.5. MOTION CONTROL
The innovative MOTION CONTROL feature enables intuitive control of the laser's functions by rotating the RC-LAR350 remote control. The built-in sensor detects your hand movements and transmits them to the laser, simplifying adjustments and alignment.
5.6. Using the REC 300 Digital Receiver
For extended range and precise height readings, use the REC 300 Digital Receiver. Hold the receiver in the path of the laser beam. The digital display will indicate the exact position relative to the laser plane, and audible signals will guide you to the desired level.
5.7. MANUAL ALIGNMENT
The MANUAL ALIGNMENT function allows you to pivot an axis in vertical operation, providing flexibility for specific alignment tasks.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your Stabila LAR350.
- Cleaning: Clean the laser unit, receiver, and remote control with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the laser exit window is clean for optimal beam clarity.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears. Always use fresh, high-quality batteries of the specified type. Remove batteries if the device will not be used for an extended period.
- Storage: Store the LAR350 and its accessories in the provided carrying case in a dry, cool place, away from direct sunlight and extreme temperatures.
- Protection: The integrated PROTECTOR system provides excellent protection against dust and water (IP65 rating). However, avoid unnecessary exposure to harsh conditions.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser not powering on. | Dead or incorrectly installed batteries. | Check battery polarity and replace batteries if necessary. |
| Laser not self-leveling. | Unit is outside its self-leveling range (+/-5 degrees). | Place the unit on a more level surface. |
| Laser beam is weak or intermittent. | Low batteries; dirty laser exit window. | Replace batteries; clean the laser exit window. |
| Remote control not responding. | Remote batteries are low or dead; obstruction between remote and laser. | Replace remote batteries; ensure clear line of sight. |
| Inaccurate measurements. | Unit not properly leveled; environmental factors (vibration, extreme temperature changes). | Ensure unit is stable and self-leveled; avoid strong vibrations or rapid temperature changes. If issues persist, contact Stabila service. |
