If your unit should not perform as expected, consult the table below to see if the problem can be corrected before seeking help
from your dealer or service representative.
If a malfunction occurs, such as no sound output, when a digital signal source (such as a CD player or DAT deck con-
nected via the digital jacks) is selected using the DIGITAL INPUT SELECTOR switches and the DIGITAL switch, the
digital source component, such as a CD player or DAT deck may be defective instead of this amplifier. Therefore, in
such a case, please consult a KENWOOD service station with the CD player or DAT deck having digital output, together
with this unit.
