NOTES:
· Missing number is allowed.
Missing number may occur in production (e.g. appearance inspection, etc).
· To identify ID data programmed, please do reading operation.
This device will be shipped in tray or other packing forms. ID cannot be identified visually (e.g. by position in
tray, marking, etc). Therefore, please do reading operation to identify ID.
· About additional ID programming charge and lead-time, please contact our sales.
