follow the operation with the button or display messages for easy programming.
If you use a large display telephone (e.g., KX-T7735), you can follow the displayed messages to use the
features. If your telephone does not have feature buttons and/or a display, you may operate the PBX by
entering a feature number instead. Follow the operation for your type of telephone.
If you use a Console, you can use the buttons on the Console as the buttons on the connected proprietary
telephone.

changed the feature number. Write the new number in "Feature Number Table" (Appendix).
•If you use a Panasonic proprietary
telephone which does not have feature
buttons, you may change one of the unused
flexible buttons to a feature button. Refer to
