Important Safety Information
- Always place the scale on a hard, flat, and stable surface to ensure accurate measurements. Avoid carpets or uneven floors.
- Do not use the scale on wet or slippery surfaces, such as in a bathroom immediately after showering, to prevent accidents.
- The maximum weight capacity for this scale is 150 kg (330 lbs). Do not exceed this limit.
- Clean the scale with a damp cloth. Do not use abrasive cleaners or immerse the scale in water.
- Individuals with pacemakers or other electronic medical implants should not use the body fat/water analysis function, as the electrical current used for measurement may interfere with these devices.
- Keep the scale out of reach of children.
Setup
1. Unpacking
Carefully remove the scale from its packaging. Inspect the scale for any signs of damage. If damaged, do not use and contact customer support.
2. Battery Installation
The Soehnle S63168 scale requires batteries for operation. Locate the battery compartment on the underside of the scale. Open the compartment cover, insert the required batteries (typically AAA, check markings inside the compartment) ensuring correct polarity (+/-), and then close the cover securely.
3. Initial Placement
Place the scale on a firm, level, and dry surface. Avoid placing it on soft surfaces like carpets, which can affect accuracy.

4. Unit Selection (if applicable)
Some scales allow you to switch between measurement units (e.g., kilograms, pounds, stones). Look for a small button on the underside or near the battery compartment, often labeled "UNIT" or "kg/lb". Press this button to select your preferred unit of measurement.
Operating Instructions
1. Power On/Off
The Soehnle S63168 scale features an automatic On/Off function. Simply step onto the scale to turn it on. It will automatically turn off after a short period of inactivity to conserve battery life.
2. User Profile Setup (for Body Analysis)
To utilize the body fat and body water content measurement features, you must first set up a user profile. The scale supports automatic recognition for up to 8 persons.
- Activate Setup Mode: With the scale off, press one of the control buttons (usually indicated by arrows or a 'SET' button) located near the display. The display will typically show a user number (e.g., P1).
- Select User Number: Use the arrow buttons to select an empty user profile number (P1-P8).
- Enter Personal Data:
- Height: Use arrow buttons to adjust your height, then confirm.
- Age: Use arrow buttons to adjust your age, then confirm.
- Gender: Select male or female, then confirm.
- Save Profile: The scale will usually save the profile automatically after the last input or by pressing a 'SET' or 'MEM' button.

3. Taking a Measurement (Weight Only)
- Gently step onto the scale with bare feet, ensuring your feet are positioned on the metallic electrodes for body analysis, or anywhere on the glass for weight only.
- Stand still and wait for the display to stabilize. Your weight will be shown.
- The scale will automatically turn off after a few seconds.
4. Taking a Measurement (Body Fat & Water Content)
- Ensure your feet are clean and dry. Step onto the scale with bare feet, placing them directly on the two metallic electrodes.
- Stand still. The scale will first display your weight.
- After a few moments, it will automatically display your body fat percentage, followed by your body water percentage.
- The scale will attempt to recognize your profile based on your current weight and stored data. If multiple profiles match, it may prompt you to select your profile using the arrow buttons.
Maintenance
1. Cleaning
Wipe the scale surface with a slightly damp cloth. For stubborn marks, a mild glass cleaner can be used sparingly. Do not use abrasive cleaning agents, harsh chemicals, or immerse the scale in water.
2. Battery Replacement
When the display shows a "Lo" indicator, it is time to replace the batteries. Open the battery compartment on the underside of the scale, remove the old batteries, and insert new ones of the correct type (e.g., AAA), observing polarity. Dispose of old batteries responsibly.
3. Storage
Store the scale in a dry place at room temperature. Avoid extreme temperatures or high humidity.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scale does not turn on. | Dead or incorrectly installed batteries. | Check battery polarity or replace batteries. |
| "Lo" displayed. | Low battery power. | Replace batteries. |
| "Err" displayed. | Overload or measurement error. | Ensure weight is within 150 kg limit. Step off and on again. Ensure feet are properly placed on electrodes for body analysis. |
| Inaccurate or inconsistent readings. | Scale on uneven surface, movement during measurement, or dirty electrodes. | Place scale on a hard, flat surface. Stand still. Clean electrodes with a damp cloth. |
| Body analysis (fat/water) not working. | Feet not bare or dry, incorrect profile setup, or user has medical implant. | Ensure bare, dry feet are on electrodes. Verify profile data. Consult a doctor if you have medical implants. |
