INSTRUCTION MANUAL
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.

Factory fitted moulded mains plug
1. The mains plug contains a fuse. For replacement, use only
a 13-Amp ASTA-approved (BS1362) fuse.
2. The fuse cover must be refitted when replacing the fuse in
the moulded plug.
3. Do not cut off the mains plug from this equipment. If the
Other
plug fitted is not suitable for the power points in your home
or the cable is too short to reach a power point, then obtain
an appropriate safety approved extension lead or adapter, or
consult your dealer.
If nonetheless the mains plug is cut off, remove the fuse and
dispose of the plug immediately, to avoid a possible shock
hazard by inadvertent connection to the mains supply.
IMPORTANT: The wires in the mains lead are coloured in
accordance with the following code:
Blue : Neutral
Brown : Live
Do not connect those leads to the earth terminal of a three-pin
plug.
Maintenance of the set
When the front panel or case becomes dirty, wipe with a soft,
dry cloth. Do not use thinner, benzine, alcohol, etc. for these
agents may cause discoloration.

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.

Notes:
1. [SL16] equipment cannot be combined with [XR],
[XS], and [XS8] equipment for system operations. If
your equipment consists of this kind of combination,
please do not connect any system control cords. Even
without system control cords, normal operations can
be carried out without effecting performance.
2. Do not connect system control cords to any compo-
nents other than those specified by KENWOOD. It may
cause a malfunction and damage your equipment.
3. Be sure the system control plugs are inserted all the
way in to the system control terminals.
Do not connect a system control cord to a cassette
deck connected to the TAPE2/MONITOR jacks.
SYSTEM CONTROL operations
Remote Control
Lets you operate this unit with the system remote supplied with the receiver.
Automatic Operation (except [XR] equipment)
When you start playback from a source component, the
input selector on this unit switches to that component
automatically.
Synchronized Recording (except [XR] equipment)
Lets you synchronize recording with the start of playback
when recording from CD, MD or analog discs.
Switching from [SL16] to [XS8]
You can easily change the system control mode by adjusting the position of the SYSTEM CONTROL switch on the
rear panel.
Do this operation after completing all connections.
For [SL16] For [XS8]
• In order to take advantage of the system control operations, the components must be connected to the correct
jacks. To use a CD player it must be connected to the CD
jacks. To use a cassette deck (or MD recorder) it must be
connected to the MD/TAPE1 jacks. When using more
than one CD player (etc.) only the one connected to the
specified jacks may be connected for system control.
• Some CD players and cassette decks are not compatible
with the[SL16] system control mode. Be sure to use the
[XS8] system control mode when making system connections with equipment that is not [SL16] compatible.

Using RDS (Radio Data System)
RDS is a system that transmits useful information (in the form
of digital data) for FM broadcasts along with the broadcast
signal. Tuners and receivers designed for RDS reception can
extract the information from the broadcast signal for use with
various functions, such as automatic display of the station
name.
RDS functions:
PTY (Program TYpe identification) Search ^
Automatically tunes to a station that is currently broadcasting the specified program type (genre).
EON (Enhanced Other Network) reservation
Sets the tuner to automatically switch to stations broadcasting one of two types of programs, even though you are
listening to another station. The tuner returns to the
original station when the broadcast of the selected program ends.
PS (Program Service name) Display
Automatically displays the station name transmitted by
the RDS station.
RDS Auto Memory function
Automatically selects and stores up to 30 RDS stations in
the preset memory.
If fewer than 30 RDS stations have been stored in the
preset memory, regular FM stations will be stored in the
remaining places.
Radio Text function
Displays the radio text data transmitted by some RDS
stations when you press the DISPLAY key. There is no
display if no text data was transmitted.
TI volume
If you preset the volume level, you can listen to the
information of your choice at that volume level automatically. After the information has been received, the volume
returns to the previous level.
The ”RDS“ indicator lights up when an RDS broadcast (signal)
is received.

To listen sources other than the tuner:
1. Tune in a station which that displays both the “EON”
and “RDS” indicators, then use the INPUT SELECTOR
to switch the input to the source you desire.
2. Even when the INPUT SELECTOR is set to a source
other than tuner, it will automatically switch to tuner
when the desired EON program starts to broadcast.
During this period, the source selected in step 1 continues playing, but will not be heard.
3. When reception of the desired EON program is com-
plete, the INPUT SELECTOR returns to the previous
input source.
•If a reserved EON program starts to broadcast during
recording, the INPUT SELECTOR switches to the tuner
and the station broadcasting the EON program is recorded.
•Do not use the EON function during recording.
