AFFIXING OF LABEL (SERIAL NUMBER)
When the front panel (SV) assy is replaced, it is necessary to affi x
the label (serial number).
2 labels (serial number) are included with a new front panel (SV)
assy. Affi x 1 label to the rear side of the front panel (SV) assy. Af-
fi x the other one to the bottom side of main unit.
Be sure to perform this procedure, as Bluetooth will not operate
correctly if the serial number of the front panel (SV) assy and main
unit do not match.
Also, since the serial number has changed, print page 13 and hand
the tear-off with the product to the customer when returning the
product after repairs are complete.
