What Kind of Telephone Can Be Used?
You can use a single line telephone (SLT), such as a rotary pulse telephone or a Panasonic proprietary
telephone (PT) such as the KX-T7737. You can also use a Panasonic Portable Station (PS), e.g., KX-

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.
Portable Station (PS) Registration
You must register your PS in the PBX and determine its extension number before initial use. For PS
registration, refer to the Feature Manual.
Feature Numbers
To use certain features, you need to enter specified feature numbers (and an additional parameter, if

for easier use. If you want to change the numbers, refer to the Feature Manual. In this manual, the default
numbers (factory installed) are used for operations.
A flexible number is shown as (half-shaded key). Use the new programmed number if you have
changed the feature number. Write the new number in the "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
