The purpose of this section is to describe the layout of the EEPROM (IC5) for the KX-TG8125 Base Unit.

The EEPROM contains hardware, software, and user specific parameters. Some parameters are set during production of the
base unit, some are set by the user configuration, and some are set during normal use of the phone.

The base unit uses a 128k bit serial EEPROM (IC5) for storing volatile parameters. All parameters are set up before the base
unit 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.

F

The data initialized by only F command

0

The data initialized by F and 0 command

1

The data initialized by F, 0 and 1 command

2

The data initialized by F, 0, 1 and 2 command

3

The data initialized by all command (F, 0, 1, 2, 3)

x

Default - no specific country setting, so revert to default value.
