Panasonic KX-TCD715EM Service Manual page 62

The base unit uses a 64k bit (8192 x 8) serial EEPROM (IC9) for storing volatile parameters. All
parameters are set up before the base leaves the factory. Some of these are vital for the
operation of the hardware so a set of default parameters is programmed before the actual
hardware fine-tuning can be initiated. This document lists all default settings with a short
description.
In the tables below values in a range that are similar are not repeated; i.e. Address 00 to 01
contains the value 00 simply means that the value 00 is repeated in all addresses in the range.
All values in this document are in hexadecimal notation.
