Setup
- Battery Installation:
Locate the battery compartment on the underside of the scale. Open the compartment cover and insert the 2 AAA batteries, ensuring correct polarity (+/-). Close the cover securely.
- Initial Calibration:
Place the scale on a hard, flat, and stable surface. Step onto the scale briefly until a reading appears, then step off. The scale will display "0.0" or a similar indication, signifying it has calibrated. For the most accurate first reading after moving the scale, disregard the very first measurement and take a second measurement.

Operating Instructions
- Standard Weighing:
Once the scale is calibrated and on a stable surface, simply step onto the center of the scale. The StepOn Activation feature will automatically turn on the scale and display your weight. Remain still until the reading stabilizes.
- Changing Units (lbs/kg/st):
On the underside of the scale, locate the unit button. Press this button to cycle through the available units of measurement: pounds (lbs), kilograms (kg), and British stones (st). Select your preferred unit before weighing.
- Tare Function (for weighing infants, pets, or luggage):
The Tare button allows you to weigh an item while holding it. First, step onto the scale alone and note your weight. Step off. Then, press the Tare button. The display will reset to zero. Now, step back onto the scale while holding the item (e.g., infant, pet, luggage). The displayed weight will be the weight of the item only.
- Automatic Shut-off:
To conserve battery life, the scale will automatically turn off after approximately 10 seconds of inactivity.
Maintenance
- Clean the scale with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water.
- If the scale will not be used for an extended period, it is recommended to remove the batteries to prevent leakage.
- Store the scale in a dry, flat location at room temperature.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Scale on uneven or soft surface (e.g., carpet); initial calibration not performed correctly. | Ensure the scale is on a hard, flat surface. Perform initial calibration by stepping on and off the scale once before taking a measurement. |
| Display shows "Lo" | Low battery. | Replace the 2 AAA batteries. |
| Display shows "Err" | Overload or measurement error. | Ensure the weight does not exceed 440 lbs (200 kg). Step off the scale and try again. If the issue persists, contact customer support. |
| Scale does not turn on | Batteries incorrectly installed or depleted. | Check battery polarity. Replace batteries if necessary. |
