DETAILED DESCRIPTION OF MAINTENANCE-MODE FUNCTIONS

3.1

EEPROM Parameter Initialization (Maintenance mode 01/91)

< 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.
Data item
Maintenance-mode functions
User switches
Firmware switches
Remote activation code
Station ID data
Outside line number
Telephone function registration
One-touch dialing
Speed dialing
Group dialing
NOTE:
If you replace the main PCB with one used for any other machine, carry out this procedure and
then customize the EEPROM
< 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.
(3) Be sure to turn the machine power off. If you press the 9 key twice to exit from the
maintenance mode without turning the power off, then the machine will not fully initialize
the EEPROM.
