How To Change Ringtone

1. Pick up the receiver: Lift the handset or press the SP-PHONE (Speakerphone) button to start.
2. Access the main menu: Press the "Menu" soft key, which is located just below the display screen.
3. Navigate to "Basic Setting": Use the arrow keys (up and down) on the navigation cluster to scroll through the options on the display. Look for "Basic Setting" and select it by pressing the "Select" soft key.
4. Enter the admin password: If the phone requires a password to access the settings, you'll be prompted to enter it. The default password is usually "1234" or "0000." If this doesn't work, consult your system administrator or the phone's user manual to get the correct password.
5. Select "Ring Tone": Once you are in the Basic Setting menu, use the arrow keys to navigate and find the "Ring Tone" option. Select it by pressing the "Select" soft key.
6. Choose a new ringtone: You'll see a list of available ringtones. Use the arrow keys to scroll through the options and listen to the different tones. When you find the one you like, select it by pressing the "Select" soft key.
7. Save the changes: After selecting the desired ringtone, press the "Save" soft key to save your changes. The phone will confirm that the new ringtone has been set.
8. Exit the menu: To exit the menu and return to the main screen, press the "Exit" or "Back" button several times until you are back at the home screen.

That's it! Your Panasonic KX-DT543 telephone should now have a new ringtone. If you encounter any issues or variations in the menu options, please refer to the user manual or contact your system administrator for further assistance.
