Most common causes for issues with consumer scales are:

1. The device is not placed on a completely flat and solid surface. 

Try to place your device on a hard and flat floor (no carpet) and see if the device works.

2. The batteries are running low

Taking batteries out and putting them back in will reset the device which might solve the issue. When batteries are running low this can result in issues with measuring. Please replace the batteries and see if that solves the issue. Please make sure not to use rechargeable batteries and replace all batteries at once.

3. The electrodes can't make skin contact

Step on the device with bare, clean and dry feet (and hands, if applicable). Ensure that there are no shoes, socks, tights, plasters or physiotherapy tape that might prevent the skin from making proper contact with the electrodes.

4. The scale has been humid or wet

If the scale is kept in a bathroom or another damp room, or has been exposed to moisture, this may cause internal faults. Place the scale in a dry room for a few days, with the batteries removed and the battery compartment open. Try using the scale again after a few days.

If the solutions suggested above don't solve the issue, please send an email to info@tanita.eu with the following information:

• The model number of your scale.
  
• Proof of purchase
• LOT-number (6 or 7-digits, found on a sticker on the back of the device)
• Clear description of the issue, if possible add a video
• Picture of the full top and full bottom of the device

Then we can try to help you solve the problem, or assess the validity of the warranty if the issue can't be solved.
