2. Safety Information

Observe the following safety precautions to prevent injury or damage to the device:

• Always place the scale on a firm, level, and stable surface to ensure accurate measurements.
• Do not exceed the maximum weight capacity of 200 kg (440 lbs).
• Keep the scale away from strong electromagnetic fields.
• Avoid exposing the scale to extreme temperatures, direct sunlight, or high humidity.
• Do not disassemble or attempt to repair the scale yourself. Contact qualified service personnel.
• Keep the weighing platform clean and dry to prevent slips.

3. Package Contents

Verify that all items are present and undamaged upon unpacking:

• Seca 874 Medical Floor Scale
• Operating Instructions Manual
• Batteries (typically included, check packaging)

4. Setup

1. Unpacking: Carefully remove the scale and all components from the packaging. Retain packaging for future transport or storage.
2. Battery Installation:
   • Locate the battery compartment on the underside of the scale.
   • Open the compartment cover.
   • Insert the required batteries (e.g., 4 x AA) according to the polarity markings (+/-).
   • Close the battery compartment cover securely.
3. Placement: Place the Seca 874 scale on a hard, flat, and stable surface. Uneven or soft surfaces (like carpet) can affect measurement accuracy. Ensure there is sufficient space around the scale for safe use.

5. Operation

5.1 Basic Weighing

1. Power On: Briefly tap the center of the weighing platform with your foot or press the power button (if present) to turn on the scale. The display will show "0.00 kg" (or lbs).
2. Step On: Carefully step onto the center of the weighing platform with bare feet. Stand still and distribute your weight evenly.
3. Read Measurement: The display will show your weight. Wait for the reading to stabilize.
4. Step Off: Step off the scale. The scale will typically hold the last measurement for a few seconds before automatically switching off (Auto-OFF function).

5.2 Mother/Child Function

This function allows for the precise weighing of infants or small children while held by an adult.

1. Weigh Adult: First, the adult steps onto the scale alone and waits for their weight to be displayed and stabilized.
2. Activate Function: While the adult is still on the scale, press the dedicated Mother/Child button (refer to scale interface for exact button, if applicable, or assume automatic detection). The scale will tare the adult's weight to zero.
3. Weigh Child: The adult then steps off the scale, picks up the child, and steps back onto the scale. The display will now show only the child's weight.
4. Complete: Step off the scale. The scale will return to normal operation or switch off.

5.3 Auto-HOLD Function

The Auto-HOLD function automatically freezes the weight display once a stable measurement is achieved, allowing the user to step off the scale and read the result comfortably.

• This function is typically activated automatically.
• Step onto the scale and stand still.
• Once the weight stabilizes, the display will indicate that the reading is held (e.g., by flashing or a specific symbol).
• You can then step off the scale, and the weight will remain displayed for a few seconds before the scale powers off.

6. Maintenance and Care

• Cleaning: Clean the scale regularly with a damp cloth and a mild detergent. Do not use abrasive cleaners, solvents, or immerse the scale in water.
• Storage: Store the scale in a dry, cool place, away from direct sunlight and extreme temperatures.
• Battery Replacement: When the battery indicator appears on the display (e.g., "Lo"), replace all batteries with new ones of the same type. Dispose of old batteries according to local regulations.
• Calibration: The Seca 874 is factory-calibrated. If you suspect inaccuracies, contact Seca customer service or an authorized service center for recalibration.
