Thank you for buying this Pioneer product.
Please read through these operating instructions so you will know how to operate your model
properly. After you have finished reading the instructions, put them away in a safe place for
future reference.
In some countries or regions, the shape of the power plug may sometimes differ from that
shown in the explanatory drawings. However, the method of connecting and operating the
unit is the same.

CONNECTIONS
INDOOR VS. OUTDOOR ANTENNAS
lf FM reception is poor when using the accessory T-type
antenna, it means that you are not living in a good reception
area. In this case, setting up a good outdoor FM antenna will
solve this problem.
AM LOOP ANTENNA
NOTE:
Any contact of the loop antenna with metal objects will result
in impaired sensitivity and a deterioration in reception.
NOTE:
Consult your dealer as to the selection and actual installation
of the FM antenna.
Accessory FM T-type antenna
Use for FM reception until a
special-purpose FM antenna is
installed.
AM LOOP ANTENNA
¢ With wood screws the antenna can
easily be installed in a location
suitable for good reception (audio
rack, wall etc.).
¢ Turn the antenna so that optimum
reception is obtained.
¢ Do not install the antenna in
locations where it touches the
equipment or other metal objects,
=
or near a CD player, personal
computer or TV set.

Although grounding is not always necessary for ——
reception, it is recommended for protection against
damage from lightning if an outdoor FM antenna is
used. Grounding is recommended as well to help
reduce noise and hum.
Note:
Never make the ground connection to a gas pipe as
sparks could cause the gas to ignite.

CONNECTIONS
OUTDOOR AM ANTENNAS
The accessory AM loop antenna is quite sufficient if you live
in a strong-signal area. However, an outdoor AM antenna
should be erected if surrounding objects are interfering with
reception, or if the stations are distant and their signals are weak.
NOTE:
Do not detach the AM loop antenna when using an outdoor
AM antenna.
GROUNDING
Grounding is recommended if reception of FM programs is
impaired by noise. To ground, connect a thick polyvinyl wire
to the GND terminal and attach the other end to a metal water
pipe or grounding bar, or wind it around a copper plate and
bury it.
NOTE:
Never connect a wire to a gas pipe for grounding as there
is the danger of a explosion in case of lightning.

© MUTING switch
The muting circuit is designed to remove the typical FM
interstation noise generated when moving away from in-tune
frequencies, but it can also prevent reception of distant or weak
signal stations. In this case, press the MUTING switch off and
tune into the desired station. Normally, leave this switch on
(MUTING indicators lit).
This switch does not affect AM reception.
NOTE:
The setting of this switch is memorized together with the
station in the station memory.
