Double Entry

"Double Entry" error message in a Binatone phone book is indicating that the number you are trying to add is already in the phone book. It could be a problem with the phone's memory, or a problem with the phone's software. Here are a few things you can try to rectify this issue:

1. Check the phone book: Make sure that the number you are trying to add is not already listed in the phone book. Look for duplicates and delete them.
2. Check the SIM card: Make sure that the number you are trying to add is not already saved on the SIM card. You can check this by going to the Contacts menu and selecting the SIM card option.
3. Reset the phone: Try resetting the phone to its factory settings. This will erase all data and settings on the phone, including the phone book.
4. Check if there is a software update available for your phone, and if so install it.
5. If none of the above steps resolves the issue, it may be a problem with the phone's memory or a problem with the phone's software. You may want to contact the manufacturer or an authorized service center for further assistance.

Please keep in mind that before trying to reset your phone, make sure you have a backup of your contacts and important data.
