Sc-405 digital scale won't display after changed batteries

The HoMedics digital scale SC-300 uses a CR2032 lithium coin cell battery. This battery has a diameter of 20mm and a thickness of 3.2mm, which makes it a small, flat battery that can easily fit into the scale.

Hello,
It's not a battery problem. The LCD panel of the DIGITAL SCALE has been wrong. Reasons: water, vapour, connector oxidation.

If the batteries are good the hassle has to be with the electronics.

If the pressure sensor is in the on position when booting, that could result in the error message you are getting - make sure it is open when booting up the unit.

I have same problem with my scale. New batteries work for a few days. I'm throwing this thing out.

change new

You may download a copy of the manual at http://dl.owneriq.net/4/419c0462-e2f0-49ea-8643-61092be935c5.pdf

if the batteries are new and the battery terminals are clean and not corroded or broken, and the battery polarity is correct when they were installed. There must be a fault in the internal circuits of the scale, and a technician with the right tools, training, and experience will be needed to repair it.
Maybe time for a new scale.

Open it again and make sure the battery is in the correct angle..... I have made this mistake from time to time

Sounds like a warranty issue. I would try to return to place of purchase if not here is web address on manufactures site with instructions on warranty.
