The machine displays the "WSW0
0" on the LCD and becomes ready to accept a firmware
switch number.
(2) Enter the desired number from the firmware switch numbers (01 through 53).
The following appears on the LCD:

(3) Use the right and left arrow keys to move the cursor to the selector position to be modified.
(4) Enter the desired number using the 0 and 1 keys.
(5) Press the Menu/Set (OK) key. This operation saves the newly entered selector values onto the
EEPROM and readies the machine for accepting a firmware switch number.
(6) Repeat steps (2) through (5) until the modification for the desired firmware switches is
completed.
(7) Press the Menu/Set (OK) or Stop/Exit key to return the machine to the initial stage of the
maintenance mode.
NOTES: • To cancel this operation and return the machine to the initial stage of the maintenance
mode during the above procedure, press the Stop/Exit key.
• If there is a pause of more than one minute after a single-digit number is entered for
double-digit firmware switch numbers, the machine will automatically return to the
initial stage of the maintenance mode.
