Operating Instructions
Taking a Measurement
- Place the scale on a hard, flat surface.
- Press the central silver power button to activate the scale. The display will show '0.0 kg' (or '0.0 lb').
- Once '0.0' is displayed, step onto the scale barefoot and stand still. Distribute your weight evenly.
- Your weight will be displayed on the LCD screen. The reading will flash or stabilize to indicate the final measurement.
- Step off the scale. The scale will automatically turn off after a few seconds to conserve energy.
Unit Conversion (Kilograms/Pounds)
The Jata 499 scale can display measurements in both kilograms (kg) and pounds (lb). To switch between units, locate the unit conversion button, usually on the underside of the scale. Press this button while the scale is off or displaying '0.0' to toggle between kg and lb. The selected unit will be indicated on the LCD display.
Maintenance
- Cleaning: Clean the scale with a soft, damp cloth. Do not use abrasive cleaners, chemical solvents, or immerse the scale in water.
- Storage: Store the scale in a dry place at room temperature. Avoid extreme temperatures or direct sunlight.
- Handling: Handle the scale with care. The tempered glass platform, while durable, can break if subjected to severe impact.
