Setup
1. Battery Installation:
The BLACK+DECKER BDSM100 requires batteries for operation (batteries are not included). Locate the battery compartment on the device, typically on the back or bottom. Open the compartment cover, insert the required batteries (e.g., 9V or AA, refer to the compartment label for exact type and quantity) ensuring correct polarity (+/-). Close the battery compartment securely.
2. Powering On/Off:
Press the power button (often integrated with a measurement button or a dedicated ON/OFF button) to turn the device on. The display should illuminate. To turn off, press and hold the power button, or the device may automatically shut off after a period of inactivity to conserve battery life.
Operating Instructions
1. Basic Distance Measurement:
- Turn on the device.
- Point the laser aperture towards the target surface from which you want to measure the distance. Ensure there are no obstructions between the device and the target.
- Press the measurement button (often labeled with a laser icon or a simple 'Measure'/'ON' button). The laser beam will activate.
- Hold the device steady until the measurement appears on the digital display.
- The measurement will typically be displayed in feet or meters, depending on the current unit setting.
2. Changing Measurement Units (FT/M):
To switch between feet and meters, press the FT/M button. The display will update to show the current unit of measurement.
3. Using the Pivoting Head:
The device features a pivoting head. Gently adjust the head to the desired angle to facilitate measurements in corners, around obstacles, or in other tight spaces. Ensure the head is securely positioned before taking a measurement.
4. Storing and Recalling Measurements:
- Storing: After taking a measurement, press the STORE button to save the reading to the device's memory.
- Recalling: To view previously stored measurements, press the RCL (Recall) button. Use the arrow or +/- buttons (if available) to navigate through the stored readings.
5. Calculation Functions (if applicable):
Some models may offer calculation functions such as area or volume. Refer to the specific instructions on the device's display or a more detailed manual for these advanced features. Typically, you would take multiple measurements and use the X (multiply), + (add), or - (subtract) buttons followed by the = button to perform calculations.
Maintenance
- Cleaning: Keep the device clean by wiping it with a soft, dry cloth. Do not use harsh chemicals or abrasive materials that could damage the casing or display.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Lens Care: The laser aperture and display screen should be kept clean and free of dust or smudges to ensure accurate readings. Use a lens cleaning cloth if necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Replace batteries with new ones, ensuring correct polarity. |
| Inaccurate or inconsistent readings. | Obstruction in laser path, dirty lens, or measuring highly reflective/absorbent surfaces. | Ensure clear path. Clean laser aperture. Measure against a non-reflective, solid surface. |
| Display shows "Error" or "Out of Range". | Measurement target is too close, too far, or the surface is unsuitable. | Ensure target is within the 40-foot measuring range. Try measuring a different surface. |
