6. An external power supply box is used along with the
unit. Customers may consult their dealers without
bringing the box.
7. You can't play your data with any HDD or product

exchange the digital units because your unit has
defects, remove IC3305: CXK2000EN from the defec-
tive unit and install it in the new unit for use.)
