6. Betjeningsvejledning
Follow these steps for basic operation of your RL-SV1S laser.
6.1 Tænding og selvnivellering
- Press the power button on the laser unit or the RC-50 remote control.
- The laser will begin its automatic self-leveling process. Wait for the laser to stabilize and emit a continuous rotating beam.
6.2 Single Slope Operation
- After self-leveling, use the slope adjustment buttons on the laser unit or RC-50 remote to set the desired slope percentage for the X-axis.
- The display will show the current slope value.
- Ensure the sensor (LS-100D or LS-80L) is correctly positioned to detect the laser beam at the desired grade.
6.3 Using the Remote Control (RC-50)
The RC-50 remote control allows for convenient adjustment of settings from a distance, including power on/off, slope adjustments, and rotation speed.
- Point the remote control towards the laser unit.
- Press the corresponding buttons for the desired function (e.g., ‘X’ or ‘Y’ for slope, ‘RPM’ for rotation speed).
7. Vedligeholdelse
Regular maintenance ensures the longevity and accuracy of your RL-SV1S.
7.1 Rengøring
- Wipe the exterior of the laser unit with a soft, damp klæde.
- Brug ikke hårde kemikalier eller slibende rengøringsmidler.
- Keep the laser aperture clean and free from dust or debris.
7.2 Opbevaring
- Store the laser in its carry case when not in use to protect it from impacts and environmental elements.
- Fjern batterierne, hvis enheden ikke skal bruges i længere tid, for at forhindre lækage.
7.3 Pleje af batterier
- If using rechargeable batteries, follow the manufacturer’s instructions for charging.
- Replace alkaline batteries promptly when the low battery indicator appears.
