5.3 DETAILED DESCRIPTION OF

MAINTENANCE-MODE FUNCTIONS

5.3.1 EEPROM Parameter Initialization

Function
The machine initializes the parameters, user switches, and firmware switches registered in the
EEPROM, to the initial values. Entering the function code 01 initializes all of the EEPROM areas,
but entering 91 does not initialize some areas, as listed below.

procedure and then customize the EEPROM (maintenance-mode function code 74 in Subsection
5.3.11).
Operating Procedure
(1) Press the 0 and 1 keys (or the 9 and 1 keys according to your need) in this order in the initial
stage of the maintenance mode.
The "PARAMETER INIT" will appear on the LCD.
(2) Upon completion of parameter initialization, the machine returns to the initial stage of the
maintenance mode.

Function code

(Note that the first digit of the 4-digit customizing
code will be initialized to "0." If the code is 1001, for
example, it will be initialized to 0001.)
