Questions about this item

How do I install the scale and what step do people often miss?

Place the scale on a hard, flat floor, insert the four supplied AAA alkaline batteries, then step on barefoot; the common miss is putting it on carpet or an uneven tile, which throws off the 13 body-composition readings.

What maintenance or replacement will the scale need later?

The four AAA alkaline batteries power 600-plus weigh-ins; when readings drift or the display dims, replace all four cells at once to restore full accuracy.

What limit appears first during sustained daily use?

Battery life is the first limit — after roughly 600 weigh-ins of 30 seconds each the AAA cells need changing, while the 400 lb capacity and 13-metric sensing remain unchanged.
