Setup
- Unpacking: Carefully remove the scales from their packaging.
- Placement: Place the scales on a hard, flat, and stable surface. Avoid carpets or uneven flooring, as this can affect accuracy.
- Initial Calibration: Before first use, ensure the pointer on the dial is aligned with the zero mark. If it is not, use the small adjustment wheel, usually located near the bottom of the dial, to manually set it to zero.

Operation
- Step On: Gently step onto the center of the scale platform with bare feet. Stand still and distribute your weight evenly.
- Read Measurement: Wait for the pointer to stabilize. Read your weight directly from the dial. The scales measure in pounds (lb) only.
- Step Off: Step off the scales. The pointer will return to zero.
Important Notes for Accurate Readings:
- Always use the scales on a firm, flat surface.
- For consistent results, weigh yourself at the same time each day, preferably in the morning before breakfast and after using the restroom.
- Avoid weighing yourself immediately after exercise or bathing.
- Ensure the pointer is at zero before each use.

Maintenance and Care
- Cleaning: Wipe the scales with a damp cloth and mild detergent. Do not use abrasive cleaners or immerse the scales in water.
- Storage: Store the scales in a dry place at room temperature. Avoid extreme temperatures or high humidity.
- Avoid Impact: Do not drop the scales or subject them to heavy impact, as this can damage the internal mechanism.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Scales on uneven surface; pointer not at zero; scales moved between uses. | Place scales on a hard, flat surface. Calibrate to zero before each use. Avoid moving scales frequently. |
| Pointer does not return to zero | Internal mechanism issue; scales not level. | Ensure scales are on a level surface. If issue persists, contact customer support. |
| Difficulty reading numbers | Lighting conditions; user's position. | Ensure adequate lighting. Stand directly over the scales to view the dial clearly. |
