B. HIDDEN PARAMETERS
The parameters in this section are separated from the Direct Access parameters because they are
infrequently changed and should not be changed by the operator. The parameters are listed in
table 5-2.
1. Turn power off, if it is on, then wait until the display goes blank.
2. Press the key and the key simultaneously. Keep pressed then,
3. Turn power on. A series of "***" will appear on the display. They will slowly dissapear.
4. Release the keys then press the key before all the stars dissapear.
5. Press the key repeatedly, until the first hidden parameter group (****SPEEDS) is
diplayed. Note that 4 stars (*) as described in section "A" above.

C. MASTER RESET
In some cases it may be necessary to reset all parameters to their default values. This is done as
follows:
1. Turn power off, if it is on, then wait until the display goes blank.
2. Press the key, key and key simultaneously. Keep pressed then,
3. Turn power on. The display alternates between "Push Set" and "For Reset".
4. Push the key within 10 cycles.
5. The word "Programming" is displayed. The parameters will be reset to their default values
after a few seconds.
D. PULLEY RATIO (RATIO BETWEEN MOTOR AND MACHINE PULLEYS)
During the initial setup and after power is first turned on. The pulley ratio must be calculated. The
pedal must be moved to the maximum forward position to do this. While the ratio is being taken,
the machine speed is limited for several stitches. After the ratio is taken, the machine will then
accelerate to maximum speed.
Each time power is turned off then back on, the ratio is checked when the pedal is moved forward
the first time. If the ratio has changed, because of a pulley change, then the ratio will be recalcu-
lated. The ratio can be displayed by pressing the and keys simultaneously. If the ratio is
correct, a star (*) will be displayed after the ratio number.
