When the FDC-250 screen is not charged in time, it will switch off. 

When you subsequently place it on the charging station, it will not switch back on by itself as you would normally do. 

By pressing and holding the red horn button (no. 8) for at least 10 seconds, your display will turn on again when it is fully charged. You can now use your FDC-250.

If you have any additional questions, you can always contact us via this website.

Please state the question or complaint clearly so that we can serve you well.
