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.

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.

New “TRAIT“ transistor
The new developed “TRAIT” transistor with extremely supe-
rior temperature characteristics is used in this amplifier‘s
amplification circuit. Through the use of this transistor, distor-
tion generated because of temperature change is kept to a
minimum resulting in “pure” sound reproduction.

advantage of convenient system control operations.
There are two KENWOOD system control modes.
Make connections according to the groups of terminal
symbols shown below.
• Some MD players are not system control compatible.
You cannot make system control connections to this
kind of equipment.
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-
nentsotherthanthosespecifiedbyKENWOOD. Itmay
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.

Tuning (non-RDS) radio stations
Radio stations can be classified into RDS (Radio Data System)
stations and other stations. To listen to or store RDS stations
in the preset memory, see the section entitled, “Using RDS”.
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.
