The Panasonic KX-T30810BE-2 is a stored program control (SPC) analogue key telephone system utilising Microprocessor control techniques. it comprises a unit incorporating a 240 volt power supply and uses three types of proprietary telephone instrument.

All power requirements are provided from the AC mains.  Visual indication of call arrival and status is given by LEDs (Light Emitting Diodes), at each telephone instrument.  Interconnection between the main unit and the extension telephone is by way of an external distribution frame (MDF), via the terminal block using 2 pair cable.

A power-fail enables one or more standard telephones to be connected to the system.  In the event of a mains power -failure the system automatically switches to basic facilities enabling users to make and receive PSTN calls only.

The apparatus must be connected to the PSTN by the connection of the incoming PTO cables to the Test Jack Frame (TJF) which is separately mounted from the main unit.

To default the system

Set the programming switch to PROGRAM and from extn 21 enter 99, then press the NEXT ( button, then press MEMORY (auto.memory) and then the END (hold) button.  Afterwards return the program switch to SET.
