2. Initial Setup
2.1 Charging the Device
The SW-S50 is equipped with a built-in 3.7V 1000mA Li-battery. Before first use, ensure the device is fully charged.
- Locate the USB charging port on the side of the device.
- Connect the provided USB cable to the device and then to a compatible USB power adapter or a computer's USB port.
- The battery indicator on the display will show the charging status. A full charge typically takes a few hours.
- Disconnect the cable once charging is complete.

2.2 Powering On/Off
- To Power On: Press the 'READ' button. The display will illuminate.
- To Power Off: Press and hold the 'OFF/CLEAR' button for approximately 2 seconds. The device also features an auto-power-off function, which will turn off the device after 150 seconds of inactivity (adjustable).
3. Operating Instructions
3.1 Basic Measurement Modes
3.1.1 Single Distance Measurement
This mode measures the direct distance between the device and a target.
- Aim the laser beam at the desired target.
- Press the 'READ' button. The measured distance will be displayed instantly.

3.1.2 Continuous Measurement (Tracking)
This mode continuously measures and displays the distance as the device moves, showing maximum and minimum values.
- From single measurement mode, press and hold the 'READ' button.
- Move the device slowly. The display will update in real-time, showing the current, maximum, and minimum distances.
- Press the 'READ' button again to stop continuous measurement.
3.2 Advanced Measurement Functions
Press the 'MENU' button to cycle through various measurement functions.
3.2.1 Area Measurement
Calculates the area of a rectangular surface.
- Select the Area measurement function from the menu.
- Measure the first side (e.g., length) by aiming the laser and pressing 'READ'.
- Measure the second side (e.g., width) by aiming the laser and pressing 'READ'.
- The calculated area will be displayed.

3.2.2 Volume Measurement
Calculates the volume of a rectangular space.
- Select the Volume measurement function.
- Measure the length, width, and height sequentially by aiming the laser and pressing 'READ' after each measurement.
- The calculated volume will be displayed.
3.2.3 Pythagorean Measurement
Used for indirect measurement of heights or distances where direct measurement is not possible.
- Select the desired Pythagorean function (e.g., two-point or three-point).
- Follow the on-screen prompts to take the required measurements (e.g., hypotenuse and one leg) by aiming the laser and pressing 'READ'.
- The device will calculate and display the unknown dimension.

3.2.4 Staking-Out Function
Helps to find positions that match a setting distance.
- Select the Staking-Out function.
- Enter the desired staking-out distance.
- Move the device along the measurement line. The display will indicate when you are approaching or have reached the set distance.
3.3 Other Functions
3.3.1 Unit Selection
Press the 'UNIT' button to cycle through available measurement units: meters (m), inches (in), and feet (ft).
3.3.2 Reference Point Setting
The device allows setting four reference points: front, middle, rear, and extension benchmark. This ensures accurate measurements from different starting points. Consult the on-screen icons to select the appropriate reference point for your measurement.
3.3.3 Electronic Level Bubble
The integrated electronic level bubble assists in ensuring the device is held level for more accurate measurements, particularly for angle-related functions.
3.3.4 Data Storage and Recall
The device can store up to 100 sets of measurement data.
- After a measurement, the result is automatically saved.
- To recall stored data, press the 'MENU' button until the data storage icon appears.
- Use the arrow buttons to navigate through the stored measurements.

4. Maintenance
4.1 Care and Cleaning
- Keep the device dry. Wipe it with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Clean the laser lens regularly with a soft, lint-free cloth to ensure accurate measurements.
- Avoid exposing the device to extreme temperatures or direct sunlight for extended periods.
4.2 Storage
When not in use, store the device in its portable bag in a cool, dry place. If storing for an extended period, ensure the battery is partially charged (around 50%) to prolong its lifespan.
