5. CORRECT USE
5-1. Data initialization
When using the sewing machine for the first time, initialize the data by following the procedure below.
1. While pressing the RESET key (1), turn on the
power switch.
* While the data is being initialized, all LEDs will
illuminate and the buzzer will sound a series of
short beeps.
* All parameters, memory switches, cycle
programs and the production counter will be
initialized.
2. When the data writing is complete, the buzzer will
stop and the machine will go to the normal starting-
up condition.
Note: The data is retained for approximately one
month after the power supply is turned off. If
more than one month passes since the power
supply was last turned on, "E-59" may be
displayed the next time the power is turned on.
If this happens, you will need to re-initialize the
data.
