the serial number can be found on the sticker on the bottom of the original paper foam case and is displayed in the format TE002/T9Y/T9Z/T9X######
(it is not TE002AS001A, that is the general product code.)
it can also be found underneath the back panel on the bottom side of the unit.
note: be careful when removing the panel not to scratch the coating of the synth.

this will take you to the "te-boot" screen. - hold [shift] and press [1].
- connect OP-1 to computer using the usb cable.
OP-1 will appear as a removable disk on your computer. - open the OP-1 folder and find the file: OP_DATA.TXT
- drag and drop OP_DATA.TXT to your desktop.
- eject the OP-1 removable disk and turn OP-1 off.
- attach OP_DATA.TXT in a support request.
- we will get back to you with your serial number.
