1. SETTING OF THE MOUNTED MACHINE HEAD

(Caution) For the function setting procedure of any operation panel other than CP-18, refer to the Instruc- tion Manual for the operation panel to be used.

1) How to enter into the function setting

mode Turn ON the power with switch

held pressed. (The item which has been changed during the previous work is displayed.)

• If the screen display does not change, re-carry out operation described in step 1). (Caution) Be sure to re-turn ON the power switch when one or more seconds have passed after turning it OFF. If the power switch is re-turned ON immediately after turning it OFF, the sewing machine may fail to op- erate normally. In such a case, be sure to turn ON the power switch again properly.

to select the mounted head. Refer to Table 1 (p.2) for the relationship between the head type and the panel display.

, and turn the power OFF. (Caution) If the power is turned OFF before car- rying out this procedure, the changed content is not updated. When switch

is pressed, the display on the pan- el changes to the previous setting No. When switch

is pressed, the dis- play on the panel changes to the subse- quent setting No. After completion of the operation, the machine is returned to the normal sewing state by turning OFF the power and re-turning it ON.

• Apply the adjustment below to the models which are not pro- vided with built-in synchronizer.

• Besuretoconrmthatthestoppositionisproperbefore performing the thread trimming operation. Adjust the stop position in the state that the synchronizer is ac- tually installed to the sewing machine. At this time, remove the connector for the sewing machine for safety's sake. When you remove a connector, please be sure to turn OFF the power. When you adjust the UP position detecting plate

, and when you turn the joint of synchronizer, please be sure to turn OFF the power. Set the needle UP/needle DOWN position setting with function No. 10 (specifying the needle bar position when the sewing machine stops).

2) Remove the cover of synchronizer

of outside UP position detecting plate

to the position of scale of DOWN position detecting plate

accordance with the respective models. For the position of scale of the respective models, refer to the list 2 (p.3).
