About the supplied remote control (RC-R0708) . . .
Compared to standard remote controls, the remote control supplied with this receiver has
several operation modes. These modes enable the remote control to control other audio
components. In order to effectively use the remote control it is important to read the operating
instructions and obtain a proper understanding of the remote control and how to switch its
operation modes (etc.).
Using the remote control without completely understanding its design and how to switch the
operation modes may result in incorrect operations.

How to use this manual
This manual is divided in to three sections, Preparations,
Operations, and Other.
Preparations
Shows you how to connect your audio components to the
receiver.
We've tried to make setting up your system as easy as
possible. However, since this receiver works with all of your
audio components, connecting the system can be fairly
complex.
Operations
Shows you how to operate the various functions available
from the receiver.
In regard to contact cleaner
Do not use contact cleaners because it could cause a
malfunction. Be specially careful not to use contact cleaners
containing oil, for they may deform the plastic component.
Other
Shows you additional information such as “In case of difficulty” (troubleshooting) and “Specifications.”

Special features
MONITOR
The TAPE2/MONITOR jacks of this unit accept the connection of a cassette deck, graphic equalizer, surround processor, etc. When a 3-head cassette deck is connected to the
TAPE2/MONITOR jacks, it is possible to monitor the sound
which has just been recorded during recording.
Station preset
This unit incorporates a function for storing received stations
in preset memory with a simple operation. It is very convenient to preset the stations you like. The preset stations can
be recalled also very easily.
RDS (Radio Data System) tuner
The receiver is equipped with a RDS tuner that provides several
convenient tuning functions: RDS Auto Memory to automatically preset up to 30 stations including RDS broadcasting
different programs and ordinary FM stations; station name
display to show you the name of the current broadcast station;
and PTY Search to let you tune stations by program type.
PTY (Program TYpe) search
Lets you tune stations by specifying the type of program
you want to hear.
EON (Enhanced Other Networks) reservation
The EON function lets you monitor information on other
stations so you can receive traffic or news programs as
soon as they are broadcast, even they are broadcast on a
station different from the one you are currently listening
to. When the broadcast ends, the receiver returns to the
original station. When listening to KENWOOD source
components connected with system control cords, the
input selector on the receiver automatically switches to
the tuner when a program you desire is broadcast.
Remote controllable audio function
By connecting KENWOOD source components such as a
cassette deck and CD player through system control connection, the basic operations of these components can be controlled from the remote control unit provided with this unit. A
single remote control unit can control the entire audio system
easily.
