If the screen of your scale doesn't turn on, perform the following steps:
- Make sure you've removed the battery tab if it's the first time you're installing the scale.
- Make sure you're using alkaline, non-rechargeable batteries.
- Make sure the metallic contacts of the battery compartment are touching the batteries and that they are not dirty or corroded.
If they are, you can clean them with a cotton swab and some rubbing alcohol.
- Make sure the batteries work properly.
You can try using new batteries to see if that's where the issue comes from.
