Disposal a nd Recycling Informati on 23 Conve rting Weight Units Press t he scale and do not measure weight until t he scale turns on and returns t o zero. Moving or bumping the scale may affect t he accuracy, i n which case you should weight again to make sure the measured data i s accurate. Auto power on when the scale i s stepped-on, with a minimum weight of 3 kg for turning i t on, and auto power off i n 10s with no measurement. Weighing Items When weighing, a flashing "Lo" i ndicates a l ow battery l evel, and you should replace the batteries as soon as possible. When weighing, a flashing "Err" i ndicates the weight being measured exceeds 200 kg, which i s bey ond the l imit of t he scale.
