7.5 DETAILED DESCRIPTION OF

MAINTENANCE-MODE FUNCTIONS

7.5.1 EEPROM Parameter Initialization (Function code 01, 91)

Function
The equipment initializes the parameters, user switches, and firmware switches registered in the
EEPROM, to the initial values. Entering the function code 01 initializes almost 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
Activity report
Station ID data
Outside line number
Telephone function registration
One-touch dialing
Speed dialing
Group dialing
EEPROM customizing code
(4-digit)
NOTE: If you replace the driver PCB with one used for any other facsimile equipment, carry out
this procedure and then customize the EEPROM (maintenance-mode function code 74 in Section
7.5.17).
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 equipment returns to the initial stage of the
maintenance mode.

Function code

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