The "REINIT" message on your Casio Digital Diary SF-3990 is an indication that the device is asking you to initialize or reset it. This could be caused by various issues, such as a low battery or a system malfunction.
To try and resolve this issue, you can try the following steps:
- Replace the batteries: The first thing you should try is replacing the batteries with new ones. Low batteries can cause errors and malfunctions, and replacing them may fix the problem.
- Perform a soft reset: If replacing the batteries doesn't help, you can perform a soft reset by pressing the reset button located at the back of the device with a pointed object such as a pen or paperclip. This will reset the device without erasing any data.
- Perform a hard reset: If the soft reset doesn't work, you can try a hard reset. This will erase all data on the device, so make sure you have a backup of your important information. To perform a hard reset, press and hold the "ON" button and the "SCHEDULE" button simultaneously for about 5 seconds until the screen displays "INIT".
- Check for software updates: If the issue persists after a hard reset, it may be due to a software malfunction. Check if there are any available software updates for your device and install them.
If none of the above steps work, you may need to contact Casio customer support for further assistance.
Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
